product description:

Gasoline generator usually consists of stator, rotor, end cap and bearing components. Engine is a machine that converts chemical energy into mechanical energy, and its transformation process is actually a process of working cycle. Simply put, it burns the fuel in the cylinder to generate kinetic energy to drive the reciproCAT-parts-partsing motion of the piston in the engine cylinder, thus driving the connecting rod connected to the piston and the crank connected to the connecting rod to make circular motion around the center of the crankshaft. And the power ones.

Compression stroke:

In order to make the combustible mixture inhaled into the cylinder can be rapidly burned to produce greater pressure, so as to make the engine emit more power, must be compressed before combustion, so that its volume is reduced, density is increased, temperature is increased, that is, there is a compression process. In this process, the intake and exhaust valves are all closed, and the crankshaft pushes the piston from bottom dead center to top dead center to move one stroke, that is, the compression stroke. At this time, the mixture pressure will increase to 0.6-1.2MPa, and the temperature can reach 600-700K. An important concept in this trip is the compression ratio. The so-called compression ratio is the ratio between the maximum volume of gas in the cylinder before compression and the minimum volume after compression. Generally, the greater the compression ratio, the higher the pressure and temperature of the mixture at the end of compression, the faster the combustion speed, so the greater the power of the engine, the better the economy. Typical cars have a compression ratio of 8-10, but the latest Polo has a high compression ratio of 10.5, so its torque is relatively good. However, when the compression ratio is too large, the combustion situation can not be further improved, but the abnormal combustion phenomena such as burst ignition and surface ignition will occur. Explosive combustion is an abnormal combustion caused by spontaneous combustion of combustible mixture at the end of the combustion chamber far away from the ignition center due to high gas pressure and temperature. In a burst fire, the flame propagates outward at a very high rate. Even before the gas has time to expand, the temperature and pressure rise sharply, forming a pressure wave that pushes forward at the speed of sound. When this pressure wave hits the wall of the combustion chamber it produces a sharp tapping sound. At the same time, it will also cause engine overheating, power reduction, fuel consumption increase and a series of adverse consequences. Serious explosive combustion can even cause valve burning, bearing rupture, spark plug insulator breakdown and other parts damage phenomenon. In addition to explosive combustion, engines with high compression ratios may face another problem: surface ignition. This is another type of abnormal combustion (also known as hot ignition or early ignition) caused by the ignition of the mixture on the hot surface of the cylinder and in hot places (such as exhaust valve head, spark plug electrode, carbon deposit). When surface ignition occurs, it is also accompanied by a strong knocking sound (more dull). The high pressure generated will increase the load of the engine and reduce its life.
