International trade compliance dictionary

engine power refers to the mechanical power output by the engine. Mechanical power refers to the ability to convert energy into physical motion,International trade compliance dictionary which is usually used to describe the output power of machinery and equipment such as engines. Definition and significance of engine power Engine power is the mechanical power output by the engine, usually in horsepower (HP) or kilowatt (kW). The definition of engine power not only includes the output power of the engine, but also covers the energy conversion efficiency of the whole working process such as engine intake, combustion and exhaust. From the perspective of mechanical energy, engine power is actually an embodiment of energy conversion efficiency.In the field of vehicles, engine power means the amount of power that the engine can provide to the vehicle, which is one of the basic indicators for judging vehicle performance. The engine power will directly affect the performance of the vehicle in the process of starting, accelerating, overtaking, etc. Therefore, it is very important to improve vehicle performance and driving comfort. The formula for calculating engine power Engine power is usually calculated using the following formula: engine power = torque × engine speed ÷ 7120 (output unit is horsepower), where torque refers to the torque applied when the engine rotates. Engine speed refers to the number of rotations of the engine per minute, which is often expressed as rotation/minute. 7120 is a constant, because when setting standards, this value can be used to convert torque and speed into horsepower. How to improve engine power? Engine power can usually be improved in the following ways: 1.Increase the speed of the engine. When the rotation speed increases, the output power will also increase. However, excessive speed will increase engine wear and increase noise and vibration. Two. Improve the exhaust performance of the engine. A better exhaust system can improve the flow and effectiveness of exhaust volume, thus improving power output and fuel utilization. 3. Improve the compression ratio. Adjusting the compression ratio of the engine can increase the pressure and temperature of the gas, make the combustion more adequate, and improve the engine power. Four. Adjust the timing of ignition. The right ignition timing can make combustion more efficient and improve engine power. However, improper adjustment will lead to incomplete combustion of the engine, resulting in harmful substances and other negative effects. The importance of engine power. Engine power is crucial to vehicle drivers and driving safety. Engine power determines the performance of the vehicle such as acceleration, driving speed and maximum speed.High engine power can make the vehicle easily overtake, climb and drive at high speed. In addition, engine power is also of great significance to cope with changes in different road conditions and road surfaces. At the same time, the engine power can also reflect the fuel economy of the vehicle. Some high-power vehicles may consume a lot of fuel under high loads, especially when driving on urban roads. For consumers, when choosing a vehicle, it is necessary to comprehensively consider factors such as engine power and fuel consumption according to actual needs. Summary Engine power is the mechanical power output by the engine, which reflects the performance of the engine by converting energy into physical motion. Increasing engine power can not only improve vehicle performance, but also help improve fuel utilization. When buying a car, choosing or modifying a vehicle, factors such as engine power, fuel consumption and driving comfort should be comprehensively considered to make the best decision.
