It can expand the ignition limit of the lean mixture. The high compression ratio makes the mixture at a higher compression state, which increases the temperature and pressure before the charge is ignited, thereby obtaining a higher combustion pressure in the power stroke, and the combustion mixture is more fully expanded, thereby improving the output power of the engine and Thermal efficiency, and due to increased thermal efficiency, the exhaust gas temperature is lowered. It is emphasized here that increasing the compression ratio can effectively improve the economics of the partial load of the ignition engine. In theory, the compression ratio is a constant geometric value, but in fact it is related to the engine load, speed and valve timing. At low load and idle speed, the actual compression pressure is reduced a lot, and the residual exhaust gas coefficient is increased, resulting in economic deterioration at partial load. At this time, if the compression ratio of the engine can be increased, the economy can be remarkably improved.
A well-designed combustion chamber shape has two parts of area that are important in the flame propagation process. First, the area of ​​the flame front, the mass burning rate of the mixture is proportional to the area of ​​the flame front, increasing the area can increase the mass burning rate; second, the wet area (the contact area of ​​the burned mixture with the combustion chamber wall), which affects The heat transfer loss of the gas body to the combustion chamber wall, the larger the wet area, the greater the heat transfer loss, so the wet area should be minimized. The flame front area is primarily related to the shape of the combustion chamber, including the location of the spark plug. A reasonable combustion chamber shape can enhance turbulence and increase the burning speed. Because the geometry of the combustion chamber has little effect on the initial combustion, it has a great influence on the main combustion period, which requires the contact area (wet area) of the flame front with the combustion chamber to be as small as possible.
