How Does a Car Engine Work?

A car is composed of thousands of individual parts. But what is really necessary to drive the car? A cigarette lighter, power windows or radio? Without them can still drive a car.

Look at the cars created over 100 years. These cars have different engines and parts such as gears, clutch and drive shaft to transfer engine power to all four wheels, brakes and steering. A seat was available and because no one wanted to take all the time. All these pieces were hung in a frame, the body.

Engine

The cars are equipped with engines powered by gasoline or diesel. Diesel fuel is more than heating oil, only a few chemical additives, so the engine run better. The core of the diesel engine is a cylinder block, cylinder, two, three, four, five or six (sometimes more). These cylinders move the piston.

At the top of the bottle, the nozzle is mounted, through which diesel fuel is injected at high pressure into the combustion chamber. The cylinder head has two valves, the intake valve and exhaust. The piston moves the cylinder bottom so that air enters through the inlet into the cylinder.

In the next phase, the piston rises and the air in the cylinder is compressed. What happened here, you may be aware of the bike. If you have an air pump and quickly pumped air into a tire air pump may become hot. This is because the air is heated. Now, the air in the cylinder is compressed and very high (about 30 to 50 times our atmospheric pressure) and thereby heated to a temperature of 700-900 ° C

Now comes the diesel fuel through the injector in the cylinder ignites at these high temperatures and immediately explodes. Now push the piston down. The outputs of the mixture of diesel combustion air exhaust outlet, so that fresh air can enter again.

two-stroke engine, this occurs when the piston descends. For four-stroke engines, with air to move upwards, then the piston moves back and repeat.

The number of cylinders (two, three or more) are connected in series so that is one after another burst of fuel. The piston is attached to the underside of the bar (left) on the motor shaft (below). This is offset by the movement of the pistons into rotary motion.
