Hyundai Damper

A damper is a device which reduces vibration.
Hyundai Dashboard This may refer to the unit found between the front driver & passenger seat that contains the automatic transmission shifter, cupholders & a storage compartment. But it can also refer to the section of the instrument panel that includes the controls for the sound system & climate-control system, particularly if the panel flows down the center of the car & includes the automatic-transmission shifter. Called a Console in USA.
Hyundai Daytime Running Lights (Drl) These lights come on whenever the car is turned on; they make the car more visible to other drivers. Mandatory in Canada & standard equipment on many vehicles sold in the United States.
Hyundai Dealer Invoice Price Also called dealer cost. The amount the dealer pays for a car or truck. Deducted from this price may be a dealer incentive, which is a set discount offered for a limited period of time, or a dealer holdback, which is a percentage of the vehicle's wholesale price.
Hyundai Decked the process of removing the body trim or contour lines from the hood or trunk of a car, usually as part of a customized design.
Hyundai Depreciation The decrease in a vehicle's market value over time. The amount of yearly depreciation is affected by car condition; resale-marketplace supply & demand; & make & model reputation. Convertibles, high-performance cars, trucks & vans tend to depreciate less than other vehicles.
Hyundai Diesel An internal combustion engine in which the air-gas mixture is ignited by compression in the cylinder rather than by a spark. Diesel engines use diesel gas rather than gasoline & tend to be more gas-efficient & require less maintenance than gasoline engines, but it is more complicated to get them to run cleanly. Also used as a slang term: after turning off the ignition, the engine continues to run for a short period.
Hyundai Diesel Engine A very high-compression combustion engine that burns diesel gas instead of gasoline. Diesel engines are known for oustanding gas efficiency.
Hyundai Diesel Engine A diesel engine uses heavier weight parts than gas engines to handle higher compression ratios. Typically, diesel engines run with greater efficiency & higher torque than similar size gas engines. These attributes lead to better gas economy & towing performance. Diesel engines do not have spark plugs or carburetors. Instead glow plugs are used to preheat air in the cylinders to ensure easy starts. Once the engine is started, compression heats the gas in the cylinders for combustion.
Hyundai Diesel Fuel Diesel gas is a heavier fuel than gasoline. Its almost an oil. Used in heavier trucks, planes, & certain cars. It has a slower evaporation rate & is cheaper than gasoline.
Hyundai Dieseling A condition in which gasoline continues to fire after the car has been shut off. In late-model engines, dieseling is caused by heat & the high manifold pressure that result from retarding the spark at idle. In gas-injected cars, gas is automatically shut off, eliminating it.
Hyundai Differential A mechanical gearbox or fluid coupling that allows wheels to rotate at different speeds. Usually located on an axle, it allows the outside wheels to turn faster than the inside wheels during cornering. Four-wheel-drive & all-wheel drive vehicles have two differentials, one for the rear axle & one for the front. all-wheel drive vehicles also may have a third or center differential on the drive shaft that runs between the front & rear axles.
Hyundai Differential A box of gears between at least two wheels that allow your engine to send power to the wheels.
Hyundai Differential The gear assembly connected to the drive shaft that permits the wheels to turn at different speeds when going around a corner, while transmitting power from the drive shaft to the wheel axles.

Hyundai Diffuser A diffuser is a rear outlet for expelling engine noise.
Hyundai Ding A small dent or scrape in the body of the vehicle.
Hyundai Direct Injection Engine An engine that used Direct Injection allows the gas to be injected directly into the combustion chamber, above the piston. Smaller diesel engines have just recently begun utilizing this technology, but large diesels have been using it for a long time. The process allows for cleaner emissions, less burn-off on operation, & increased full-throttle power.
Hyundai Directional Stability A vehicle's ability to maintain a true course of travel despite bumps, crosswinds, uneven road surfaces.
Hyundai Disc Brakes This system uses a rotor that rotates at the same speed as the wheel, & a caliper lined with brake pads straddles it. Small pistons that squeeze against the disc to slow it down & stop it operate these. These are more efficient than drum brakes during high temperatures & in wet conditions.
Hyundai Disc Brakes Properly called caliper disc brakes, a type of brake that consists of a rotor that rotates at wheel speed, straddled by a caliper that can squeeze the surfaces of the rotor with brake pads near its edge. Disc brakes provide a more linear response & operate more efficiently at high temperatures & during wet weather than drum brakes.
Hyundai Displacement The volume displaced by an engine's cylinders. Formerly measured in cubic inches, now, in liters.
Hyundai Displacement In an engine, the total volume of air or air-gas mixture an engine is theoretically capable of drawing into all cylinders during one operating cycle. Generally expressed in liters or cubic inches. Engine displacement is equal to (bore) x (bore) x (stroke) x (number of pistons) x (.785).
Hyundai Distributor Part of the ignition (electrical) system. Delivers electricity from the ignition coil to the distributor cap & the spark plug wires in the correct firing order. (The firing order is that sequence in which each cylinder begins its power stroke.) The spark plugs ignite the gas & air mixture in each cylinder thousands of times a minute, producing the explosion that pushes the piston down in the cylinder to power the vehicle.
Hyundai Distributor The part of the ignition system that distributes the current to the spark plugs. These typically do not "wear"--they either work, or they don't.
Hyundai Distributor A part of the ignition system, usually driven by the camshaft that directs high-voltage surges to the spark plugs in the proper sequence.
Hyundai Distributor Assembly Central to an ignition system on gasoline engines, an electro-mechanical device which receives a high voltage spark via an ignition coil & transmits that spark, in a firing order, to each of the engines’ spark plugs.
Hyundai Distributor Cap The phenolic cover on the top of a distributor assembly, whose job it is to send fire to each spark plug via a set of spark plug cables, according to the in a sequential firing order.
Hyundai Distributor Rotor A phenolic part which sits just underneath the distributor cap & whose duty it is to receive a spark from the ignition coil via a cable usually connected to center of the cap & transmit that spark according to the vehicles’ firing order, to the terminals located inside the distributor cap & on to the spark plugs via the spark plug wires.

Hyundai Drivetrain This is often referred to by manufacturers, especially in regards to warranty coverage. Though definitions can vary, it mainly refers to primary engine & transmission parts that make the car "go."
Hyundai Drivetrain The power-transmitting parts in a car, including clutch, gearbox (or automatic transmission), driveshaft, universal joints, differential & axle shafts.
Hyundai Drum Brakes A drum brake uses cylindrical, cast iron housing that contains curved brake shoes that are forced into contact with an inner drum to provide braking to stop a vehicle. They are simple & effective, but less effective than disc brakes under harsher conditions. Many times drum brakes will be used on the rear brakes & disc brakes on the front.
Hyundai Dual Exhaust System With a dual exhaust system, there is “breathing” capacity in the engine, & there are less exhaust gases in the engine at the end of each exhaust stroke. This lowers the back pressure, & there is a sizable increase in horsepower above a traditional engine.
Hyundai Dual Overhead Camshafts (Dohc) A DOHC engine has two camshafts in each cylinder head; one camshaft actuates intake valves & the other actuates exhaust valves. The camshafts act directly on the valves, eliminating pushrods & rocker arms. This reduced reciprocating mass of the valve train enables the engine to build RPM more quickly. DOHC designs are typically high-performance, four valve per cylinder engines. (A four valve per cylinder two intake & two exhaust design helps the engine "breathe" more freely for increased performance.)
Hyundai Dynamometer A device which absorbs & measures the power derived by an internal combustion engine.
Hyundai EBD Electronic Brake Distribution is a part used with ABS an usually a brake assist mechanism, for small powerful cars, like the new Mini of 1998.

Hyundai Electronic Mufflers In an electronic muffler system, sensors & microphones in the exhaust system sense the pattern of exhaust pressure waves. This information is sent to an on-board computer that manages loudspeakers in the muffler. The computer operates the loudspeakers to generate sound waves that oppose & cancel the original exhaust sound waves produced by the engine.
Hyundai Electronic Sensor Any number of devices that measures some engine factor & transmits a signal (i.e. reading) to the engine's computer. These can & do fail, & can muck up the way your engine runs in any number of ways, though thankfully they can often be tested with an ohmeter before you start--to great expense--replacing parts.
Hyundai Electronic Stabilization Program (ESP) increases car control in situations near the vehicle's limits. It reduces the risk of skidding & helps to keep the car on course. ESP recognizes the course desired & the car's reactions. Through brake application at individual wheels, it generates one-sided forces which help the car to move in the desired direction. The ESP program uses other driving aids & is permanently engaged.

Hyundai Emblems Any of a number of insignias on a car which represent the vehicles’ make or model.
Hyundai Emergency Brake Shoes The parts which, when the emergency brake is applied, push outward against the interior of the rear brake rotor, so as to prevent the car from moving.
Hyundai Engine The basic job of an engine is to take gas & convert its energy to some usable mechanical form (burn gasoline to spin a shaft and, ultimately, the wheels). Usually made from alloy & block. Its Cubic Capacity number [cc] represents the interior gas space within it. The higher cc# the greater power it generates. Most vehicles today are fitted with what is known as a 4-cycle internal combustion engine. The four cycles are: Intake, Compression, Power, Exhaust.
Hyundai Engine Computer Different manufacturers refer to these on-board "computers" by unique initialisms--ECM, ECU, etc.--but fundamentally most are the same: they use inputs from various engine sensors to control the engine's operation.

Center of the fifth wheel should always be located ahead of the centerline of the rear axle.
Hyundai Final Drive Ratio The reduction ratio of the transmission gear set furthest from the engine. In other words, the ratio of the number of rotations of the drive shaft for one rotation of a wheel. In general, a low final drive ratio results in better gas efficiency, & higher final drive ratio results in better performance.
Hyundai Final Drive Ratio A fluid coupling consists of two fan-like impellers in a sealed, oil-filled housing. The input "fan" churns the oil, & the churning oil, in turn, twirls the output "fan." Such a coupling allows some speed difference between its input & output shafts. The automatic transmission's torque converter is based on the fluid coupling principle.
Hyundai Firewall The metal panel that separates the engine compartment from the passenger compartment. It also often includes sound & heat insulation.
Hyundai Firing Order The sequence in which spark plugs fire & combustion takes place in the engine cylinders.

Hyundai Formula Racing The most popular, sophisticated, & expensive of all the forms of auto racing is Formula 1 [F1]. It tends to be dominated by European drivers, who race through non-ovular circuits around the globe. The parallels to Indy Car racing have lead to the defections of drivers like Nigel Mansell, who sought the greater spoils of victory in the US, even though the technical expertise an racing challenge are lower their. Formula 2, 3, an 4 are lesser versions of F1, in terms of finance, spectacle, an Skillman-ship. Since 1970, F2 cars have tended to succeed in the Le Mans 24hr race. Of the 3 cars from left of the picture below, they represent F1, F2, & F3. Next is a rally car, then a vintage racer, & right-most is a touring-car racer.
Hyundai Four Wheel On a car equipped with Four-Wheel Anti-Lock Brakes, all four wheels are equipped with speed sensors. When these sensors determine that the wheels are decelerating so rapidly that lockup may occur, the Electro-Hydraulic Control Unit (EHCU) is activated. The EHCU then modulates the brake pressure in the appropriate brake lines by means of the solenoid-operated valves. This is intended to prevent wheel lockup & help the car maintain directional stability during potentially hazardous braking situations
Hyundai Four Wheel Drive (4WD) In a Four Wheel Drive system, a secondary transmission assembly, called a transfer case, is driven from the main transmission. The transfer case distributes power to both axles to drive all four wheels. It is the heart of the Four-Wheel Drive system. Four-Wheel Drive can be full-time, in which power is delivered to both axles at all times or part-time, where the driver selects two or four wheel drive. Four wheel drive is often combined with independent suspension systems & off-road type tires to enhance driveability on rough, off-road terrain, or on-road driveability in unfavorable driving conditions.

Hyundai Free Pedal Play If your clutch pedal feels all loose-and-goosey, its freeplay is probably out of adjustment. "Freeplay" is the distance, usually measured in inches or fractions of an inch, that the clutch pedal can be depressed before it starts to "work," or disengage the clutch.
Hyundai Front Wheel Drive The front wheels are the ones that are being powered by the engine/transmission, & the rear wheels just follow along. Generally speaking, these cars are more gas-efficient than their rear-wheel drive counterparts, & they operate more easily in snow, but they are more expensive to build & maintain.
Hyundai Front-Wheel Drive (FWD) A drive system where the engine & transaxle parts apply the driving force to the front wheels rather than the rear wheels. Benefits of Front-Wheel drive include: Maximized passenger space. Enhanced cargo area. excellent drive traction; particularly on wet or slippery surfaces, since the drive is through the front wheels, which carry a heavier load.

Hyundai Fuel Cell The name for a volumous gas tank used in formula racing cars, that sits behind the driver an is reinforced with Kevlar.
Hyundai Fuel Filter Usually hard to find in the engine bay, & about the size of a can of your favorite cola, the gas filter's job is to--you guessed it, filter the gas, removing dirt, grit, & other nasty stuff that could clog your other parts of your gas system. These should be changed per manufacturer recommendation, & while doing this jod yourself isn't difficult, anytime you mess with gas system parts, the margin for error is much smaller. When things get hot, gas is a dangerous thing.
Hyundai Fuel Injection A system that injects gas directly into the cylinders of an internal combustion engine to avoid the need for a carburetor.
Hyundai Fuel Injection Most modern engines have their gas supplied to them by a gas-injection system, as opposed to the older, dated design of carbureted gas systems. Fuel-injected engines are more efficient, as they are able to control the gas more precisely.
Hyundai Fuel Injection A method of delivering gas under pressure into an engine's combustion chamber. Fuel injection systems can be single-point, multi-point, etc.. Replaces carbureted system.
Hyundai Fuel Injection System Injects gas into the engine's cylinders with electronic control to time & meter the gas flow.
Hyundai Fuel Injection, Electronic A computer-controlled method of delivering gas under pressure. The computer monitors signals from coolant temperatures, manifold vacuum, exhaust oxygen sensor, & engine cranking sensor. It "tells" the injectors to release & adjust the gas to yield an air/gas mixture assuring engine operation well matched with emission requirements, optimum gas economy & overall car performance.
Hyundai Fuel Injector An electrical or mechanical device which meters tny amounts of gas into a combustion chamber.
Hyundai Fuel Injector O’ Rings The rubber o’rings used to prevent gas from leaking around the injector.
Hyundai Fuel Pump The gas pump delivers gas to the engine. It must maintain proper pressure in the carburetor & pump so that the gas doesn’t boil, & it helps to prevent vapor lock. Fuel pumps generally deliver a minimum of ten gallons of gasoline per hour.
Hyundai Fuel Pump A mechanical or electrical device that draws gas from the gas tank & delivers it to the carburetor or injectors
Hyundai Fuel System These systems are vast & countless, but today's basic systems divide into two fundamental groups: carburetor systems & gas Injection systems. Carburetor systems work by allowing the vacuum created by the engine in the intake stroke to pull gas & air into the engine. Fuel Injection systems are more common these days. Sensors & computer manages monitor various engine speeds, air flows & throttle positions, & then tell the system what to do. A gas pump is used to transfer the gasoline from the gas tank to the injector (which is kind of like a spray nozzle).
Hyundai Galvanized Steel A specially zinc-coated steel used on many major painted panels & in key unpainted areas of a car to help prevent rust & corrosion.
Hyundai Gap Insurance Stands for Guaranteed Auto Protection insurance. Extra insurance for lease customers to cover the difference in the actual value of the car & whatever is owed on the lease. Important if the car is stolen or totaled early in the lease term. It also covers the difference in value between what may be paid by an insurance carrier & what is still owed to the leasing company, including future lease payments.

Hyundai Gas Cap Gasket A rubber gasket which seals between the gas cap & the gas filler tube.
Hyundai Gas Filled Shock Absorbers A nitrogen gas chamber is used to pressurize the shock absorber in place of the traditional air/oil combination. Gas filled shock absorbers provide more stable damping in a variety of conditions & thus improves ride & road contact.
Hyundai Gas Pedal The gas pedal is what the driver pushes with his foot to make the car go. It is connected to a throttle valve by a cable. When the driver pushes down on the pedal, the valve opens, & the engine speed increases. When the pedal is released, the car slows.
Hyundai Gas-Charged Shocks Also called gas-filled shocks. They are shock absorbers filled with a low-pressure gas to smooth the vehicle's ride during up-and-down movement.
Hyundai Gasket A thin, expanding material used to seal the gaps & imperfections between hard, adjoining surfaces.
Hyundai Gasket Gaskets are literally everywhere in your vehicle. Your car is composed of thousands of parts, many of which are joined together. Sometimes the seal between these parts--between the cylinder head & the engine block for example, is crucial. In these cases, a gasket is used to help provide a proper seal. These gaskets can be made of paper, cork, rubber, or metal plates, & can often fail, requiring replacement to keep more expensive parts from failing.
Hyundai Gaskets Gaskets are used along with seals to keep joints fit & tight. This keeps fluids & gasses in the engine from leaking.
Hyundai Gear Ratio The ratio of teeth counts between meshing gears.
Hyundai Gear Ratio Gear ratios mathematically determine the relationship between your engine & your transmission. Gear ratios are chosen by manufacturers to provide desired performance characteristics like acceleration & gas efficiency. These do not change unless the gears themselves are physically replaced, & are not "wear" items.
Hyundai Gear Ratio The number of revolutions a driving (pinion) gear requires to turn a driven (ring) gear through one complete revolution. For a pair of gears, the ratio is found by dividing the number of teeth on the driven gear by the number of teeth on the driving pinion gear.
Hyundai Gearbox A metallic enclosure containing several cogs, each one affecting the effort in which the car moves. Each cog/gear has a different mph ratio per 1000rpm. Overall control maybe manual via the gear stick, automatic, or semi via a hand paddle.
Hyundai Gearbox A housing containing gears, such as a transmission. Gearbox just sounds cooler, doesn't it?
Hyundai Generator A device that converts mechanical energy into electrical energy. It can produce either AC or DC electricity. Seldom used in automotive applications, it has been replaced by the alternator.
Hyundai Global Positioning System (GPS) GPS units are installed in many vehicles to help drivers navigate from one destination to another. They employ satellites maintained by the U.S. Department of Defense to provide audible turn-by-turn directions for drivers as they travel. For those who do not have the devices installed in their vehicles, portable GPS units are also available, & these can be mounted on the dash.
Hyundai Glow Plug An electrical heating element which heats usually for a few seconds & enables a diesel engine to achieve combustion when the engine is cold.
