Governor The governor is a safety device in most modern cars. It regulates the car's speed by mechanically preventing the car from going over a certain speed. So, though a car may be mechanically capable of going 180 miles per hour, the governor can be set to limit its speed to 120 miles per hour. Once a diesel engine is running, the engine speed is monitored and controlled through a governor.  The governor ensures that the engine speed stays high enough to idle at the right speed and that the engine speed will not rise too high when full power is demanded.  The governor is a simple mechanical device which first appeared on steam engines.  It operates on a diesel engine as shown in the diagram below. The governor consists of a rotating shaft, which is driven by the diesel engine.  A pair of flyweights are linked to the shaft and they rotate as it rotates.  The centrifugal force caused by the rotation causes the weights to be thrown outwards as the speed of the shaft rises.  If the

Flywheel A flywheel is a heavy wheel, where energy is stored as momentum. In cars, the flywheel sits between the engine and the transmission. It spins, storing energy from the engine. When the transmission engages the flywheel, that energy is transferred.

Engine The engine takes up most of the space under a car's hood and provides power to the entire automobile. It does this through internal combustion. The engine takes fuel, like gasoline, adds air and a spark, to create a series of small explosions. Those explosions move components inside the engine, which in turn power other components that make the car move

Drivetrain A car's drivetrain includes all parts that make or send power to the wheels. For most cars, the drivetrain refers to the engine, transmission, driveshaft, differentials and drive wheels.

Differential A differential is part of a transmissions gear system. It allows one wheel to turn faster than the other Car Differential is a small device that helps in splitting the torque of your car’s engine in such a manner, which will allow the wheels to move at different speed. These differentials play an important role while turning of the car. Car differential is a small device, which splits your car engine’s torque in two ways and allows each output to have a spin in different speed. Car differential is found in all modern cars . Differentials are also found in most trucks and all-wheel drive vehicles. All-wheel drive vehicles require a differential between each of their drive wheels set. They also require one in between the front & back wheels too, as the front wheel travels different distances while turning than what is travelled by the rear wheels. Part-time 4-wheel drive systems do not have car differentials between their front & rear wheels. Instead , what you’ll

Cylinder On an internal combustion engine, a cylinder is the space in which the combustion takes place. It also houses the piston and connecting rod. By looking at an engine's cylinder block, you can tell what kind of engine the car has. If the cylinders are in a straight line, it's an inline engine. If there are two rows of cylinders facing each other at an angle, it's a V engine. It the cylinders are in two rows, but lying flat across from each other, it's a horizontally opposed or boxer engine. The number of cylinders, as well as their layout, tells you if the engine is an inline four, V8 or another type. Cylinders are also sometimes called bores

Crankshaft The crankshaft is a rod that is connected to the pistons in an engine. As the pistons move up and down due to combustion, they rotate the crankshaft. This rotational force travels down a car's drivetrain and eventually powers the car.

Clutch A clutch connects and disconnects the transmission from the engine, allowing the flow of energy to momentarily stop so the transmissions gears can be changed. In an automatic transmission, this happens without driver input. In a manual transmission, the clutch must be disengaged before the driver changes or selects a gear

Carburetor In older cars and some motorcycles, the carburetor mixes the correct amount of air with fuel to create internal combustion. In modern cars, this is done automatically by the fuel injection system.

Body-on-Frame In this type of car design, the car's body is a separate unit from its chassis or frame. This is a common form of construction for older cars, as well as modern trucks and some SUVs. Most modern cars use unibody construction

Automatic Transmission An automatic transmission routes the engine's power to the wheels with little input from the driver. It selects gears and changes them at an appropriate time based on set parameters. This is the most common type of automotive transmission in the United States.
