The front and rear axles are cross members supporting

a vehicle where the wheel hubs are attached. Axles are also part of your suspension system and are responsible for sending power to the wheels from the engine through the transmission and differential. They link the wheels to the vehicle and support the weight of each.

The chassis and body, analogous to the skeletal structure in the human body, provide support for

all the various systems and components, while also providing safety, comfort, and protection from the elements for the automobile's passengers

The function of the air intake system is to

allow air to reach your car engine. Oxygen in the air is one of the necessary ingredients for the engine combustion process

The exhaust system, with its muffler,

also acts to reduce the noise produced by the vehicle

Timing Belt:

an engine component, is a cogged belt, usually of reinforced rubber. The purpose of a timing belt component is to provide a quiet, flexible connection between the camshaft and crankshaft to keep the engine valves opening and closing in phase with the movement of the engine pistons.

Power is defined as the rate at which

an object does work. In the context of automobiles, power is often described as horsepower

Fuel economy is measured in mpg

and refers to how far a car can go using a set amount of fuel

Piston:

another vital engine component. It is a partly hollow cylindrical part closed at one end, fitted to each of the engine's cylinders and attached to the crankshaft by a connecting rod. Each piston moves up and down in its cylinder, transmitting power created by the exploding fuel to the crankshaft via a connecting rod.

The wheels, suspension, steering, and braking systems are all

attached to the car's chassis, as is the rest of the automobile

Drum brake systems mostly consist of a

brake drum and shoes

In addition to the cylinders, other ducts and passageways are

built into the block that allow for oil and coolant to flow to different parts of the engine.

The engine converts the chemical energy produced

by the burning of the fuel into mechanical energy

The spinning shaft, through the interaction of the transmission and other components

causes the wheels to turn and the car to move

The battery stores energy in

chemical form so it can be released as electricity to run your vehicle's electrical components

The engine block is also referred to as the

cylinder block because of the big hole or tubes called cylinders that are cast into the integrated structure

The combustion chamber is made up of the

cylinder, piston, and cylinder head

Manual Transmission

A manually shifted gearing device in the power train that allows variation on the relationship between engine speed and road speed

Battery Terminal

A means of connecting the battery to the vehicle's electrical system. The three types of battery terminals are post or top, side, and L.

Fuel tank

A storage tank for gasoline that powers your vehicle

Automatic Transmission

A transmission in which gear ratios are changed automatically using automatic transmission fluid (ATF). Shifts are controlled by the engine computer. Some automatic transmissions are continuously variable (CVT), or shiftless transmissions which can change seamlessly through a continuous range of effective gear ratios.

Cold Cranking Amps

Abbreviated CCA, this refers to the amount of current that the battery can supply to the vehicle

The alternator is an

electricity-generating device that converts mechanical energy to electrical energy in the form of alternating current. It is used to supply power to your vehicle's electrical system along with the battery. The alternator also recharges the battery using mechanical energy generated by the motion of the vehicle's parts.

The muffler comes just before the

end of the exhaust pipe and is responsible for reducing the noise emitted by the exhaust system. It restricts exhaust gas flow, which leads to a quieter ride. Some mufflers restrict gas flow more or less, which results in quieter or louder exhaust noise respectively.

The cylinder is where the

engine's pistons slide up and down

Burning fuel in the cylinders produces two other results:

friction and extremely high temperatures

The shoes are covered in

friction material that is pressed against the inside of the drum to create friction and slow the vehicle

An internal combustion engine is called an "internal combustion engine" because

fuel and air combust inside the engine to create the energy to move the pistons, which in turn move the car

The electric starter motor of an automobile provides a powerful force to

give the engine its initial movement

The radiator is a

heat exchanger used to remove heat from the coolant in the cooling system to prevent your vehicle's engine from overheating

fuel economy measures

how much distance a car gets out of fuel

fuel consumption discussing

how much fuel a car consumes to go a certain distance

catalytic converter

is an automotive exhaust-system component, made of stainless steel, containing a catalyst to reduce oxides of nitrogen (NOX), and/or hydrocarbon (HC), and carbon monoxide (CO), in tailpipe emissions. It is used to remove pollutants and make exhaust gasses less harmful to the environment.

The AC Compressor

is responsible for pumping coolant throughout your system and starting the process of cooling your car

A cylinder

is the power unit of an engine; it's the chamber where the gasoline is burned and turned into power.

The job of the exhaust system is to

keep dangerous gases out of the vehicle and prevent occupants from getting sick and to quiet the exhaust noise

A sliding caliper is used to

measure the distance between two points on a flat surface. To measure the distance between two points where one or both may be on a rounded surface, please see our range of GPM spreading calipers

However, a true fuel efficiency should be expressed by a percent which measures how

much of the fuel is used to power the movement of the car

The tailpipe is the

pipe that carries exhaust fumes from the muffler or catalytic converter to the rear of the vehicle

The transmission is a gearing device of a vehicle that

provides variable ratios between the engine output and the differential input

The alternator is driven by a belt attached to the engine

recharging the battery so there will be a constant supply of energy

This energy is used to

spin a shaft

Fuel consumption measures

the amount of fuel a car consumes to go a specific distance

Once an automobile is moving, it will continue to move until some sort of friction

the brake, is applied to stop it

Since this is the inverse of fuel consumption

the larger the value, the better the rating

The group size is just what it sounds like

the size of the battery

Shock Absorbers are a hydraulic device used at each wheel of the suspension system to help control

the up, down, and rolling motion of a car body by dampening the oscillations or jounce of the springs when the car goes over bumps, thereby contributing to vehicle safety and passenger comfort

In order to protect the parts from being worn down from the friction and from melting with the heat

they must be properly lubricated and cooled

the tires are the only parts of the automobile that are actually in contact with the road

they must rest on a system of supports that will carry the weight of the car and respond to conditions of the road surface

It's where fuel, air, pressure, and electricity come together to create the small explosion that moves the car's pistons up and down

thus creating the power to move the vehicle

The engine's power is used

to turn the automobile's wheels

Car engine compression refers to

when air and gas are mixed together in the cylinders of an engine. This process is required for the car to move and function

The battery supplies energy for the engine to use

when burning the fuel needed to make it run

Contrast that to an external combustion engine

where fuel is burned outside the engine and the energy created from that burning is what powers it.

Coal is burned outside of the engine

which heats water to produce steam, which then powers the engine.

Caliper

Non-rotational components of disc brakes that straddle the disc and contain hydraulic components forcing the brake pads against the rotor to slow or stop the vehicle. Can be found in the front or rear of a vehicle.

A typical shock absorber has three functions

Reduce the tendency of a tire tread to lift off the road surface (a problem often caused by static unbalance)

A typical shock absorber has three functions

Control body sway

A typical shock absorber has three functions

Dampen the effect of spring oscillation in order to control the ride stabilization of a vehicle

Flywheel

Flywheel is one of the most important engine components. It is a large and heavy metal wheel. Flywheel is attached to the back of the crankshaft to smooth out the firing impulses. It provides inertia to keep the crankshaft turning smoothly during the periods when no power is being applied. It also forms a base for the starter ring gear and in manual transmission, for the clutch assembly.

Brake Rotor

Disc-shaped component that revolves with hub and wheel. The lining pads are forced against the rotor to provide a friction surface for the brake system, to slow or stop a vehicle

Cylinder Block:

It is actually housing where all engine components reside. It is a metal casting containing the cylinders and cooling ducts of an engine. The cylinder block is extremely strong so it can withstand the rigors of engine torque and vibration, while supporting all attached engine accessories and the transmission. Cylinder block is a complicated component at the heart of the engine, with adoptions to attach the cylinder head, crankcase, engine mounts, drive housing and engine ancillaries, with passages for coolants and lubricants.

Battery Capacity

The energy output of a battery measured in amp/hours

Crankshaft:

The major rotating part of the engine. It converts the reciprocating (back-and-forth) motion of the piston into rotary (circular) motion.

Brake Pad

The pad of friction material that is pressed against the disc by the caliper, to slow or stop a vehicle. It is also a term often used for brake lining

Spark Plug:

These plugs have two primary functions. Engine spark plug ignites the air/fuel chamber and removes the heat from engine combustion chamber.
