Car Parts and Their Functions

Automatic Transmission

An automatic transmission, also called auto, self-shifting transmission, n-speed automatic (where n is its number of forward gear ratios), or AT, is a type of motor vehicle transmission that can automatically change gear ratios as the vehicle moves, freeing the driver from having to shift gears manually.

Exhaust Pipe

The exhaust pipe is the pipe that carries the gas out of the engine of a vehicle.

Fuel System

The fuel system in a vehicle is the combination of parts needed to carry fuel into and out of the engine.

Engine

There are three main components that make up a combustion engine. the piston, crankshaft, and the valvetrain. They work in unison to pump air and fuel, and also turn the wheel.

Fuel Tank

a container inside a vehicle that holds fuel

Catalytic Converter

a device incorporated in the exhaust system of a motor vehicle, containing a catalyst for converting pollutant gases into less harmful ones.

Piston

a disk or short cylinder fitting closely within a tube in which it moves up and down against a liquid or gas, used in an internal combustion engine to derive motion, or in a pump to impart motion.

Fuel Filter

a filter in the fuel line that screens out dirt and rust particles from the fuel, normally made into cartridges containing a filter paper. They are found in most internal combustion engines.

Fuel Injections

a filter in the fuel line that screens out dirt and rust particles from the fuel, normally made into cartridges containing a filter paper. They are found in most internal combustion engines.

Fuel Pump

a frequently (but not always) essential component on a car or other internal combustion engined device. Many engines (older motorcycle engines in particular) do not require any fuel pump at all, requiring only gravity to feed fuel from the fuel tank or under high pressure to the fuel injection system.

Valvetrain

a mechanical system that controls operation of the valves in an internal combustion engine, in which a sequence of components transmits motion throughout the assembly.

Muffler

a part of a motor vehicle's exhaust system, serving to muffle the sound of the vehicle.

Crankshaft

a shaft driven by a crank.

Cooling System

a system that keeps air cool and dry. coolant system. a cooling system that uses a fluid to transfer heat from one place to another. cooling tower. a cooling system used in industry to cool hot water (by partial evaporation) before reusing it as a coolant.

Manual Transmission

an automotive transmission consisting of a system of interlocking gear wheels and a lever that enables the driver to shift gears manually.

Oxygen sensor

an electronic device that measures the proportion of oxygen (O2) in the gas or liquid being analysed. It was developed by Robert Bosch GmbH during the late 1960s under the supervision of Dr. Günter Bauman. ... This resulted in a sensor that started sooner and responded faster.

Exhaust manifold

collects the exhaust gases from multiple cylinders into one pipe. ... Exhaust manifolds are generally simple cast iron or stainless steel units which collect engine exhaust gas from multiple cylinders and deliver it to the exhaust pipe.

Exhaust System

is usually piping used to guide reaction exhaust gases away from a controlled combustion inside an engine or stove. The entire system conveys burnt gases from the engine and includes one or more exhaust pipes. ... Cylinder head and exhaust manifold. A turbocharger to increase engine power.

Transmission

the mechanism by which power is transmitted from an engine to the wheels of a motor vehicle.

Exhaust Stroke

the movement of an engine piston (as of a 4-stroke-cycle engine) that forces the used gas or vapor out through the exhaust ports.

Power Stroke

the stage of the cycle of an internal combustion engine in which the piston is driven outward by the expansion of gases.

Intake Stroke

the stroke in the cycle of an internal-combustion engine during which the fuel mixture is drawn in before compression.

Compression Stroke

the stroke in the cycle of an internal-combustion engine in which the gases are compressed before firing.

Drivetrain

the system in a motor vehicle that connects the transmission to the drive axles.

Suspension

the system of springs and shock absorbers by which a vehicle is cushioned from road conditions.
