The engine – the internal combustion engine, which is in almost any modern machine. Of course, the last time the world had electric cars running on electric motors, but 95% of cars fitted with internal combustion engines. What is it in the car and how it works? Let's take a closer look at this question.

DVS what it is in the car

Principle

The Machine with the internal combustion engine (engine) should go, and for this it is necessary to make mechanical effort. It produces motor, which transmits rotational force to the wheels of the car. Those rotate and the vehicle starts moving. This is a very simplistic explanation, which will only vaguely understand what it is – the engine in the car.

The Main purpose of the engine – the conversion of gasoline (or diesel fuel) into mechanical motion. Today the easiest way to make a car move – to burn fuel inside the engine. That is why the internal combustion engine got its name. They all work on the same General principle, although there are some species: LPG, with a carburetor or injector power supply systems and so on.

Then we realized: the fuel burns, it releases substantial amounts of energy that push mechanisms in the motor that causes rotation of the crankshaft. Efforts are then transmitted to the wheels, and the car starts to move.

Let's now take a closer look at what it is in the car – the internal combustion engine.

Theory

If you put a small amount of gasoline in an enclosed space and ignited, it will burn, releasing a large amount of energy in the form of expanding gas. If you create a cycle of such blasts (up to hundreds of times per minute), then the released energy can be used for the movement of the vehicle. This is what makes the engines. Inside them creates a cycle of explosions of gasoline and the energy released keeps the wheels of the car.

Almost all cars currently equipped with four-stroke engines. There the combustion is carried out in 4 steps:

  1. Intake of the fuel mixture.
  2. The compression.
  3. Combustion.
  4. Exhaust.

Main engine components

The figure Below shows the arrangement of elements in the cylinder. Depending on the engine model, there may be 4, 6, 8 and even more.

DVS what it is in the car

In the figure represent the following elements:

  • A – camshaft.
  • B – flap valves.
  • C – an exhaust valve. Opens strictly at the right time in order for the exhaust gases were evacuated outside of the combustion chamber.
  • D – a vent for exhaust gases.
  • E – head of the cylinder Assembly.
  • F – a space filled with coolant. In operation, the engine heats up, so it must be cool. Most often this is antifreeze.
  • G – the motor housing.
  • H – oil pan.
  • I – pan.
  • J – spark plug. Provides the spark necessary to ignite the fuel mixture under pressure.
  • K – the intake valve. Opens and starts the combustion air / fuel mixture.
  • L – the inlet of the fuel mixture.
  • M – the piston. Moves up and down following the detonation of the fuel mixture, passing mechanical load on the crankshaft.
  • O – the connecting rod. The connecting element of the piston and the crankshaft.
  • P – a crankshaft. Is rotated by the movement of the pistons. Transmits the force to the wheels via the car's transmission.

All these elements participate in the four-stroke cycle.

Internal process

the car with engine engine

Here's what happens inside during operation of the motor:

  1. The Piston is at the top, at this time, open the valve of the fuel mixture. However, he moves down, sucking the fuel mixture of gasoline and air. This is the first step. Then a drop of gasoline mixed with air (without it, the gasoline will not burn) and goes inside.
  2. Second measure. The piston reaches the bottom center, the intake valve closes, and he moves again up. Wherein the fuel mixture is compressed and reaches its peak when the piston is in the highest possible point.
  3. When the piston is at the top, and the fuel mixture is compressed to the limit, the spark plug emits a spark, causing the gasoline ignited. Being under the strong pressure, the mixture explodes, pushing the piston back down. It is connected to the crankshaft via the connecting rod, and when moving down from the explosion force is transmitted to the crankshaft, so that and rotated.
  4. The Fourth stroke-the exhaust. When new the piston moves up exhaust valve opens, gases under pressure out of the combustion chamber and through the exhaust pipe discharged outside.

This process is carried out continuously during operation of the engine and occurs in all blocks. After the fourth stroke (the exhaust) into the combustion chamber receives a new air-fuel mixture, and then repeated again. The movement of allpistons connected with the crankshaft, the latter is actively untwisted. Through the transmission is the transmission to the wheels of the car. Almost all models of cars with internal combustion engines operate on this principle. The engines can vary by location and the number of blocks, but the essence does not change.

Now you know what it is – the engine in the car, and how it works. And how it is run?

How to start the car with the engine?

The Car starts with the rotation of the key in the ignition. While turning it is the closure of certain contacts, causing the starter is energized. He begins to rotate and starts the engine.

In some vehicles is key is the push button ignition. Simply click on it. Then spun the starter and the engine will start.

Conclusion

Internal combustion Engines have existed for many years and will be relevant for several more decades. They are constantly evolving and improving. Motors developed today, can not yet compete with automotive internal combustion engines. There are even RC car with engine – expensive toys for adults. There is the principle of operation of the power plant is the same, but all the elements are reduced in accordance with the scale.

Perhaps, now we understand what it is – the engine in the car, but this is only a theory that tells even in schools.
