The Global import export data subscriptionimpact of gasoline engine compression ratio on engine performance. Gasoline engine is one of the common engine types in our life. Its compression ratio is one of the most core parameters of the engine. The compression ratio refers to the ratio of the maximum volume and the minimum volume in the cylinder, which directly affects the combustion efficiency and power output of the engine. This article will discuss the impact of gasoline engine compression ratio on engine performance from the following two aspects. I. The impact of compression ratio on combustion efficiency. The engine uses the calorific value of fuel to convert energy into mechanical energy. The key is to fully burn the fuel and convert chemical energy into thermal energy, so as to promote the movement of the automobile. Gasoline can achieve better combustion effect at high temperatures, and the compression ratio is one of the important factors affecting the combustion temperature. With the increase of the compression ratio, the density of the mixed gas in the cylinderAs it increases, the temperature and pressure also increase, making it easier for the fuel to be ignited, and more thorough combustion can be achieved while injecting and igniting. In this way, the energy utilization rate of the engine will be higher and the fuel consumption will be more economical. However, the contribution of compression ratio to combustion efficiency is not linear. When the compression ratio increases, the impact of the increase in the temperature of the mixed gas on the combustion efficiency is no longer as severe as expected. On the contrary, due to the spontaneous combustion of gas under high temperature and high pressure conditions, the mixed gas spontaneously ignites prematurely in the combustion chamber, forming an explosion, which reduces the efficiency of the engine. Therefore, the compression ratio can only be adjusted within a reasonable range to achieve the best combustion effect. II. The impact of compression ratio on power output The operating capacity of the engine directly determines the acceleration and driving stability of the car. According to the engine theory, there is a direct relationship between compression ratio and power output.Engines with higher compression ratios can show higher mechanical efficiency, stronger power output and more uniform torque characteristics. When the gasoline mixture is compressed to a certain extent, the gas pressure in the combustion chamber will increase. This pressure forces the gasoline mixture to burn rapidly in the combustion chamber. After combustion, the high-temperature and high-pressure gas will spread along the piston, pushing the connecting rod to drive the crankshaft to rotate, thus driving the car forward. Therefore, the influence of compression ratio is very large. Generally speaking, the higher the compression ratio, the greater the actual output power, and the smaller the initial kinetic energy required to start the engine. However, the compression ratio should not be too high. When the compression ratio is too high, the heat generated during the engine load and fuel combustion will increase, which will lead to excessive heating of the engine and excessive consumption of lubricant. At the same time, it will also produce ultra-high temperature and pressure, which will lead to the aggravation of wear of the piston and cylinder liner, easy to jam and other adverse effects.Therefore, the selection of compression ratio needs to be comprehensively considered based on various factors such as fuel properties and engine structural parameters. Summarizing the compression ratio is one of the key factors for the performance of gasoline engines. When developing and applying automobile engines, engine structure, fuel performance, emissions and other factors should be fully considered to ensure that the compression ratio is within a moderate range to achieve better power output and fuel utilization. In addition, in the process of using the car, we should also pay attention to maintenance and regular replacement of oil products to ensure the normal operation and long service life of the engine.
