performance attributes of some vehicles.

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.
This burning, or combustion, takes place an a high speed termed as an ”explosion”. The high pressure thus created causes a shaft to turn or rotate.

This rotary motion is transmitted to the car so the wheels rotate and the car moves. Most automobile engines have four or six cylinders, although some eight-, twelve- and sixteen cylinder engines are in use.

liquid gasoline and to deliver it to the engine cylinders on the intake strokes in the form of vapour mixed with air.
The fuel system must vary the proportions of air and gasoline vapour to meet the requirements of the various operations conditions.
The fuel system 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.
The carburetor is designed to mix each pound of gasoline with 9 to 15 pounds of air under various operating conditions.

brakes.
It is clear that without brakes the car is quite helpless. They must be well and strongly made.
It is necessary to give them close and careful attention.

There are two sets of brakes, one for ordinary service, called the service brakes, and the other for emergency use, called the emergency brakes. Sometimes both are mounted inside the same drum. Sometimes one is outside and the other - inside The service brake is operated by a pedal. The emergency brake is operated by a lever.

vehicle that cools the engine.
The primary job of the cooling system is to keep the engine from overheating by transferring this heat to the air, but the cooling system also has several other important jobs. The engine in the car runs best at a fairly high temperature. When the engine is cold, components wear out faster, and the engine is less efficient and emits more pollution.
So another important job of the cooling system is to allow the engine to heat up as quickly as possible, and then to keep the engine at a constant temperature.

HOW THE ENGINE IS WATER-COOLED?

The majority of engines are cooled by means of water. The cylinder head, the combustion chamber and the valve seats are surrounded by hollow spaces known as water jackets. They are filled with water. These jackets are connected by pipes to the top and to the bottom of the radiator. The radiator is mounted at the front of the car. There are two circulating methods: pump and thermo-syphon.
Behind the radiator a fan is provided to blow cool air on the tubes containing water. It is driven by a belt from a pulley on the crankshaft.
