NEW TOPIC: Automotive mechanical terms:
List it and what it is....must be mechanical like in power train, drive train, suspension, braking etc.

For example: A is for...

ABS: Abbreviation for Anti-lock Brake System.
A computer, sensors, and solenoid valves work together to sense wheel speed in order to modulate braking force if wheels lockup during braking.

Air cleaner element: The replaceable filter which prevents impurities from the air which enters the combustion chamber.

Baffle
[1] An obstruction (e.g., plate or vane) used to slow down or divert the flow of gases, liquids, sound, etc. They are found in the fuel tank, crankcase, muffler, and radiator.
[2] Plates fitted between cylinders of air-cooled engines to assist cooling.

Camshaft
A shaft with Cam lobes (bumps) which is driven by gears, a belt, or a Chain from the crankshaft. The lobes push on the Valve lifters to cause the valves to open and close. The camshaft turns at half the speed of the crankshaft.

Carburetor:
a device that blends air and fuel for an internal combustion engine in the proper ratio for combustion. It is sometimes colloquially shortened to carb in North America or carby in Australia.[1] To carburate or carburet (and thus carburation or carburetion, respectively) is to blend the air and fuel or to equip (an engine) with a carburetor for that purpose.

Drive Shaft

A drive shaft, driveshaft, driving shaft, propeller shaft (prop shaft), or Cardan shaft is a mechanical component for transmitting torque and rotation, usually used to connect other components of a drive train that cannot be connected directly because of distance or the need to allow for relative movement between them.

Electronic Control Unit (ECU)
A generic term for any embedded system that controls one or more of the electrical system or subsystems in a transport vehicle.

Fuel injection (FI):
A fuel delivery system in which nozzles (injectors) spray fuel into the intake manifold or cylinders,allowing for more precise fuel control and better fuel efficiency than
can be achieved with a carburetor.

Gas Tank

The place where the gas goes.

Harmonic balancer
A device connected to the crankshaft of an engine to reduce torsional vibration and to serve as a pulley for drive belts.

Ignition switch or starter switch is a switch in the control system of an internal combustion engined motor vehicle that activates the main electrical systems for the vehicle

Journal
That part of a shaft that is prepared to accept and support a bearing. The area on the crankshaft that fits into the lower portion of the Connecting rod. A layer of oil and metal bearing cushions the impact during the Power stroke to prevent the crankshaft from being crushed by the swiftly descending piston and Connecting rod.

Knock sensor

knock sensor is to sense for vibrations that are caused by the detonation or knock of the engine

Light Switch

Operating this switch causes the lights to come on or go off.

Leaf spring
A leaf spring is a simple form of spring commonly used for the suspension. A length of Flat spring steel plates bent in an arch usually with curled ends (eyes) to allow mounting to the frame. The eyes are usually filled with rubber bushings to reduce noise when the leafs flex.

Lockup torque converter
A Torque converter fitted with a lockup clutch that can be engaged to eliminate the slip between the torque converter's input and output, thereby improving fuel efficiency and performance because it is now in direct drive mode...

Manifold absolute pressure sensor
(MAP)

A detection device which monitors the engine's intake manifold pressure and transmits the data to the engine controller. A pressure-sensitive disk capacitor used to measure air pressure inside the intake manifold. The Map sensor sends a signal to the computer which uses this information to determine load conditions so it can adjust spark timing and fuel mixture. Also called Manifold pressure sensor or Pressure differential sensor

Nitrous Injection

This is a system that one can install when one needs to make horsepower but does no have the skills or knowledge to do so correctly.

Oxygen sensor :
All cars that were manufactured post 1980 feature an oxygen sensor. It is located within the emissions control system. When functioning, the O2 sensor sends data to the management computer located within the engine. In your car, a functioning O2 sensor ensures that your engine is running at top performance. Additionally, this sensor keeps your emissions in check and alerts you to when emissions are too excessive.

Pushrod engine
An engine configuration where the camshafts are located lower in the engine. Connecting rods and other components are used to operate the valves at the top of the cylinder heads

Quick Release Steering Wheel Hub

A device that allows one to quickly remove the starring wheel for ease of ingress/egress.

Rich air-fuel mixture
A mixture of air and fuel in which there is less air and more fuel.

Steering Wheel

The round thing that sits in front of the driver.

Turbocharger

A magical device that, when placed inside of an engine bay, makes cars go faster

Underbody Ground Effect

a device that mount at the bottom of the vehicle with the purpose of creating a suction when traveling at or higher than certain speed thus providing more downforce on the vehicle therefore increase traction at speed.

Valve float
A condition where the valves in the engine are forced back open before they have had a chance to seat. Brought about (usually) by extremely high rpm. The Valve lifters lose contact with the cam lobes because the Valve springs are not strong enough to overcome the Momentum of the various Valvetrain components. The onset of valve float prevents higher-rpm operation. Extended periods of valve float will damage the Valvetrain. Also called Valve bounce

Washer Fluid Reservoir

This is an annoying container that adds unneeded weight and takes up unnecessary space.

Wankel Engine

Invented by Mr Felix Heinrich Wankel, a different kind of internal combustion engine which uses the combustion force to push a triangular rotor into rotation thus rotate the crankshaft.

X- Pipe
An X-Pipe or and exhaust H-Pipe are bolted in the center of the car. Also known as a crossover pipe, each system works by balancing the exhaust pulses from either side—or cylinder bank of a V-style engine. The result is a smooth exhaust flow and a more efficient engine.

Y-Pipe

it is an adapter mostly use on engine with 6, 8 or more cylinders with design of using single exhaust pipe, it connects both exhaust manifolds and before the catalytic converter.

Zerk fitting
A small valve that allows grease to be added to a Ball joint with a Grease gun and prevents the grease from leaking out when pressure is placed on the area. Incorrectly pronounced zert. Also called Grease fitting
