In our days, hardly a surprise in this invention, as the internal combustion engine. Millions of various devices they are used for their functioning. There was the invention of this type in the 19th century, and it was due to the necessity of creating a modern and efficient mechanism, which could result in the movement of the technical device. Originally it had many disadvantages, and the efficiency was extremely low. Subsequently, it has undergone various changes, has been improved and now we have the opportunity to use the invention. In particular it is used in the design of the motorcycle.

Two-stroke engine like any other engine, is the heart of technology. Regardless of the type, its primary task is to ensure the movement of the connected mechanisms. Almost everyone knows how it looks and where it is installed, but how it works, understand not all. Try now this question to understand.

The Engines of modern motorcycles have a number of differences and the main ones are:

  • Method operations

There are four - and two-stroke engines. These are almost two times more power with the same amount of cylinders with four-stroke counterpart. But this advantage is highly conditional. First, they have relatively low efficiency. Therefore, they are used in applications that require light weight, small size and unimportant question of economy in fuel consumption. This makes these units ideal for use in motorbikes, small motor boats, bensalah, chainsaws, etc.

  • Cooling Method

The Engine may be air or liquid cooled. In view of the small size two-stroke engine most often it is supplied with air cooling. In his device, everything is aimed to minimize its weight.

  • Volume

A Large amount of provides plenty of power.

Four-stroke engines popular, economical, productive, but most motorcycles use two-stroke engines. This preference is primarily due to the simple design of the motor, its low weight, low fuel consumption. Negative point is the fact that the filling of the combustible mixture is inadequate. This peculiarity is connected with bad cleaning of cylinders from the exhaust mixture of gases.

The Principle of operation of the two-stroke engine based on a short operating cycle, which occurs during one revolution of the crankshaft.

During the upward movement from bottom dead center (BDC) to top dead center (TDC) of the piston creates a vacuum which ensures the supply to the crankcase the fuel-air mixture. At this point in the combustion chamber compress the fuel (mixture). Then in the top dead point, the working mixture lights up and expands and moves the piston down to BDC.

Modern two-stroke engine differs little from its predecessors, in connection with this scheme of supply of fresh fuel mixture and the output of the mining occurs in these units is about the same.

Now consider another version of the engine with the valve “disc” type.

During the movement of the piston down in the crankcase pressure increases, thereby closing the Poppet valve. At this time, the piston provides the opening of the exhaust Windows, and tested working mixture in the form of exhaust gas flows into the receiver. The next step of movement of the piston towards BDC is the opening of the inlet ports, of which receives a fresh charge of the working mixture. Two-stroke engine continues its work. The cycle repeats itself, providing the movement of the motorcycle.

The Principle of operation of the two-stroke engine ensures long life of the bike, as the system is simple and does not contain much detail. It is resistant to many factors (whether poor quality fuel or oil) and powerful enough to cope with its responsibilities.
