One of a group of chambers in the engine where the combustion process takes place. Most configurations are set in either 4, 6 or 8 cylinders.
D
Disc Brakes

A disc brake is a type of brake that uses callipers to squeeze pairs of pads against a disc or a "rotor" to create friction.
Drivetrain
(Photo Credit: X-Engineer.org)
A drivetrain includes components of a vehicle that create power and transmit that power to the wheels, excluding the engine or motor.
E
Electronic Stability Control
(Photo Credit: AutoBuzz.my)
A type of safety feature that detects skids and adjusts braking pressure to maintain the direction of the vehicle.
Exhaust Drum Brakes
(Photo Credit: Wikipedia)
It is a braking system that uses a metal drum. Brake shoes press against the drum to slow or stop the car.
Engine Management System

The pipe through which waste gas from the combustion process are removed from the engine and car.
F
Front-Wheel Drive
A drivetrain that provides power to the front wheels by driveshafts.
Fuel Injection System

The fuel injection system delivers fuel into the engine cylinders while controlling the injection timing, fuel atomization, and other parameters.
G
Gearbox

A gearbox transmits the power of the engine to the wheels. It acts to transmit different levels of power.
Glow Plugs

Glow plugs are used in diesel engines to heat the combustion chamber so that the diesel compresses and expands rapidly.
Grille

The grille is the opening on the body of a vehicle that allows air to enter or exit. It also serves as an aesthetic element to the car.
H
Hip Point
(Photo Credit: Wikipedia)
It is the distance between the pivot point of a person's hips, the vehicle floor, and the ground.
Horsepower

The standard unit of engine power. One horsepower equates to 550 foot-pounds per second.
Hybrid Engine

A type of engine with a battery-operated electric motor and an internal combustion engine. These engines can operate jointly or alternately.
I
Intake Charge

The mixture of fuel and air that combusts in the engine to create power.
L
Leaf Spring

The powertrain includes both the engine and/or motor(s), as well as the drivetrain.
R
Rear-Wheel Drive
A drivetrain that transmits power to the rear wheels only. The front wheels are used for steering.
Revs
An Engine Revolution (rev) occurs every time the pistons in the car travels up and down the cylinders. The more the revs, the more power.
RPM
(Photo Credit: AutoGuru)
Revs per minute. The revolution of an engine per minute.
Rubbing Strip
Protective strips moulded to fit around the door.
S
Scoop
(Photo Credit: Wikipedia)

Sill
Any extensions to the body of the vehicle.
Spark Ignition (SI) Engine

Spark plugs are used in petrol engines to ignite the petrol and air mixture to make the engine produce power.
Spoiler
(Photo Credit: CARS.com)
A spoiler is an aerodynamic device designed to 'spoil' unfavourable air movements (aka drag) as the car travels.
Stroke
