It is the source of power that makes the wheels go around and the car move. It is usually referred to as an internal combustion engine because gasoline is burned within its cylinders or combustion chambers.

On this stroke the valve is opened. The piston is moving down, and a mixture of air and vaporized gasoline is being drawn into the cylinder through the valve opening. The mixture of gasoline and air is delivered to the cylinder by the fuel system.

After the piston reaches BDC it begins to move upward and at this instant the intake valve closes. The other valve is also closed so that the cylinder is sealed. The piston moves upward, compressing the mixture to as little as one sixth of its original volume or less. This creates a high pressure within the cylinder.

As the piston reaches TDC or the upper limit of its travel, an electric spark is generated at the cylinder spark plug. The spark ignites or sets fire to the highly explosive mixture of gasoline vapor and air. Rapid combustion takes place.

As the piston reaches the lower limit of its travel again, this valve opens. The piston moves upward on the exhaust stroke, forcing the burned gases out of the cylinder through the exhaust-valve opening. The piston once more reaches top dead center, the exhaust valve closes and the intake valve opens so that, when the piston begins to move downward on the intake stroke.

It is designed to store liquid gasoline and to deliver it to the engine cylinders on the intake strokes in the form of vapor mixed with air. It consists of a tank in which the liquid gasoline is stored, a fuel line, or tube, through which the gasoline can be brought from the tank to the engine, a pump, which pulls the gasoline through the fuel line, and a carburetor, which mixes the gasoline with air.

It consists of a rocker arm, a flexible diaphragm, and two valves. The rocker arm rests against a cam on the camshaft so that rotation of the shaft makes the arm rock.

It, located at the rear of the vehicle and attached to the frame, is merely a storage tank made of sheet metal. It often contains a number of metal plates, which are attached to the inner surface of the tank parallel to the ends.

It must be transmitted to the car wheels, so that the wheels will rotate and cause the car to move. It consists of a series of gears and shafts, which mechanically connect the engine shaft with the car wheels, and contains a clutch, a transmission or change gears, a propeller shaft, and the final drive.

It permits the driver to connect the crankshaft to or disconnect it from the power train. It is placed in the power train between the crankshaft and transmission. It permits the engine to run freely without delivering power to the power train.
