ENGINE

The engine 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.

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.

STEAM ENGINE.

The steam engine was the first high-speed engine ever invented. The principle of the steam engine is simple. When water is boiled, it changes in to steam. The more the steam is heated, the more pressure it has.

A steam engine has some important parts. One is a boiler where fire turns water into steam. The steam goes through a pipe to the other important part - the steam chest with a cylinder and a piston in it. There are valves, or openings, in the steam chest. As the piston moves in the cylinder, it opens and closes the valves automatically, so that fresh steam enters just when the piston has reached the end of its stroke. A rod from the piston is connected to a wheel.

Now steam engines are mostly used in locomotives.

DIESEL ENGINE

A diesel engine is like a gasoline engine but simpler. Diesel engines are usually larger and can do more work. The fuel used in a diesel engine is oil. In diesel engines only air is blown into the cylinder. It does not need spark plugs. Diesel engines can be four - stroke ones and two - stroke ones.

Diesel engines use a cheaper kind of fuel and give more power for each gallon of fuel burned than gasoline engines. Besides they last much longer. In new trains and ships diesel engines run large generators which make electricity. The electricity runs motors which are connected to the wheels of the train or to the ship's screws.

The diesel engine is an internal combustion engine. It uses oil as a fuel. The fuel is introduced in the form of spray and the engine requires no special ignition device.

In the four-stroke cycle Diesel engine air alone is drawn into the cylinder on the charging stroke. This air is being compressed on the return stroke to a very high pressure. The result of the combustion is that the air is heated to a high temperature.

The heavy oil injected into the air at the end of the stroke will be immediately ignited by It. The oil burns rapidly, but without explosion. The compression pressure is much higher than that in any other oil or gas engine.

3. Answer the questions:

1. What happened at the end of the stroke?

2. Is in the four-stroke cycle Diesel engine air or petrol drawn into the cylinder on the charging stroke?

3. What is the result of the combustion?

4. What is fuel used in a diesel engine?

5. A diesel engine is like a gasoline engine but simpler, isn’t it?

WНАТ IS AN INTERNAL COMBUSTION ENGINE?

The gasoline engine is that type of machine where power generated within the cylinders. The engine is set in motion by the explosions of a mixture of gasoline and air.

Combustion takes place above the pistons. The detachable head is secured to the top of the cylinder block. It encloses the cylinder block and forms the combustion chamber. When the fuel is burnt within the cylinders the expansion of gases is used for producing piston movement. Such a type of engine is called the internal combustion engine.

In any internal combustion engine the gas charge is drawn into the cylinder.

The internal combustion engine converts heat into mechanical energy by burning a mixture of oil fuel and air within its cylinder or cylinders. The internal combustion engine consists of the following: 1. A cylinder (there may be several). 2. A piston which moves up and down inside cylinder. 3. A crankshaft connected to the piston by a rod known as a connecting rod. The connecting rod turns the up-and-down motion of the piston into a rotary motion of the crankshaft. 4. A flywheel which keeps the crankshaft moving when the pressure is exerted upon the top of the piston. 5. Two valves known as the inlet valve and the exhaust valve. 6. A camshaft which is used to open and close the valves. 'Combustion engines may be divided into types according to the duration of the cycle on which they operate. By a cycle is meant the succession of operations in the engine cylinder which constantly repeats itself. The great majority of modern automobile engines operate on the four-stroke cycle.

It is completed in four strokes of the piston, or during two revolutions of the crankshaft. Engines are also being built to operate on a cycle which is completed in two piston strokes. The four-stroke cycle comprises the following four phases or operations, which succeed one another in the order in which they are given: Admission of the charge to the cylinder. Compression of the charge. Combustion of the charge. Expulsion of the products of combustion.

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. In the pump system, the pump is placed in the bottom water passage. It is driven by the engine and forces the cooled water into the jackets. It forces the heated water to the top of the radiator where it is cooled again.

In the thermo-syphon system of water cooling there is no pump. The system is based on the fact; that hot water is lighter than cold water and has a tendency to rise. So when the water in the jackets of a thermo-syphon cooled engine gets hot, it rises to the top and enters the radiator through the upper pipe. Here it is cooled and goes to the bottom of the radiator and from there back to the jackets. The circulation is entirely automatic and continues as long as there is a difference in temperature between the water in the radiator and that in the jackets. There is a variety of designs in the structure of the radiators The two main types are tubular and honey comb type.

In the tubular type а series of flat vertical tubes connect two tanks. The honey comb type is built up of short tubes placed horizontally. Their ends are soldered together, making a labyrinth of narrow spaces between the tubes. These spaces are filled with cooled water. Tubes of various shapes are used round, square, hexagonal. A cock is placed at the lowest point of the radiator to drain off water when it is necessary. 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.

FUEL SYSTEM

The fuel system is designed, to store 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 not necessary to explain the importance of 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.

DRIVIHG SYSTEM

When the motor - car has to be sat in motion first of all it is necessary to start the engine. When the engine is running you start the car. By means of a pedal, the operator at his will, connects or disconnects the engine with the transmission. This device is called a clutch. Clutches are divided into two main groups: cone clutches and disc clutches. In the former group two cone surfaces are used to convey the drive. The cones are normally pressed into contact with one or another by means of a single powerful coil spring. This type of clutch is old and is now used only to a limited extent. There exist two types of disc clutches: the multiple disc type, and the single plate type.

There exist two types of disc clutches: the multiple disc type and the single plate type. The, multiple clutch is composed of a number of driving and driven discs.
