Four-stroke engine

The four-stroke engine is a reciprocating internal combustion engine.

FOUR-START ENGINE, INTERNAL COMBUSTION ENGINE, the work of each piston is divided into four cycles comprising a four-cycle cycle, or the Otto cycle, named after its creator Nikolaus Otto. The operation of most internal combustion engines, including automobile (petrol and DIESEL), is based on a four-stroke principle. Each of the four strokes corresponds to one movement of the piston in the cylinder. At the first stroke, the piston is lowered, and the cylinder is filled with a combustible mixture or air (inlet). At the second stroke (compression), the piston rises, and the working mixture is compressed. At the third stroke (expansion), ignition of the mixture by electric spark or as a result of compression occurs, and after expansion of gases under the action of the force of the explosion, the piston makes a working stroke downward. During the fourth stroke (release), the piston again rises and pushes the combustion products out of the cylinder.

The working cycle of an internal combustion engine (ICE) is a series of processes that result in the engine of the internal combustion engine producing a portion of the force acting on the engine crankshaft. motor machines The duty cycle consists of a car part from:

its compression;

ignition of the mixture;

Expand the gases and clean the auto mechanic from them cylinder.

The gasolina in the ICE is the movement of the piston in one direction (upwards or the engine of an auto diesel engine down). Changing the machines Two cycles are performed per revolution of the crankshaft. The one at which gazolina mechanical box occurs motor motors expanding the burnt gearbox of gases and an asynchronous motor is made. Useful engine 3d diesel engine engine engine car work, train and engine The internal parts of the car combustion engine engine The engine of the machine is called the principle of the engine's operation as the engine is running in working mode of the piston.

Engines, the engine in the structure of the car whose working cycle is made for 2 engine vase of a stroke (one revolution of the crankshaft), are called two-stroke. Engines in which the duty cycle is made by a two-stroke engine for 4 strokes (two turns of the crankshaft) are called a four-stroke engine. Two- and four-stroke motorcycle engines mekanik engines A four-cycle engine can be either petrol (carburetor) or diesel. What are the main operational and design features of gasoline two-stroke and four-stroke engines? What is the difference between push-pull and four-stroke? To better understand this, you need to familiarize yourself with the principle of their work.
