Pre-export HS code verification steps

Gasoline engine efficiency With the continuous improvement of people's requirements for car experience,Pre-export HS code verification steps the efficiency of gasoline engines has received more and more attention. How to improve the efficiency of gasoline engines has become one of the research focuses of manufacturing and scientific research institutions. This article will discuss how to improve the efficiency of gasoline engines from many aspects. 1. Improve the quality of fuel. As an internal combustion engine, the performance of gasoline engines mainly depends on the quality of fuel. Improving the quality of fuel can greatly improve the efficiency of gasoline engines and reduce their pollution to the environment. At present, many research institutions at home and abroad are using new fuel additives, such as adding ethyl acetyl propionate or dihydroxymethylbutyl ester to improve the calorific value of gasoline, so as to improve the efficiency of gasoline.Two. Optimize the ignition system and combustion chamber design. In order to maximize the calorific value of gasoline, the key is to optimize the ignition system and combustion chamber design. The ignition system is responsible for lighting the fuel gas mixture, and the optimization of the combustion chamber design can convert the thermal energy of gasoline into mechanical energy as much as possible while ensuring sufficient combustion. Therefore, when researching and developing, Hyundai will optimize the ignition system and combustion chamber design to improve the efficiency of gasoline engines. 3. Increase the engine speed. The increase of the gasoline engine speed can also improve the efficiency of the gasoline engine to a certain extent. Generally speaking, increasing the speed of the engine by 20%~30% can increase its thermal efficiency by 5%~10%, which is very beneficial to improving engine efficiency. However, increasing the speed of the engine will also have a certain impact on the durability of the engine, so it needs to be considered when designing.Four. The use of micro-hybrid, hybrid and other new technologies. With the development of new energy technology, some new technologies have also been introduced into the automobile industry, among which micro-hybrid, hybrid and other technologies are more representative. Micro-hybridding refers to the use of on-board batteries to power the engine during the shutdown or inertial taxiing of the bus station, which avoids the energy loss caused by the sharp reduction in the speed of the engine, thus improving efficiency. Hybrid power uses the electric motor and engine on the car to drive the car together, thus improving efficiency. 5. The weight of cars using lightweight materials is one of the important factors affecting their fuel efficiency. Therefore, the use of lightweight materials is an effective way to improve the efficiency of gasoline engines. Nowadays, the automobile manufacturing industry has learned from advanced lightweight materials in the aviation industry, such as aluminum alloy, titanium alloy, carbon fiber materials, etc., to reduce the weight of the whole automobile.Lightweight cars can use less energy to complete the same task with the same performance, thus improving the efficiency of gasoline engines. In summary, gasoline engines have a history of more than a hundred years as traditional vehicle equipment, and their technology and craft have been very mature. However, automobile manufacturers are still trying to adopt new technologies and materials to improve the efficiency of gasoline engines. The modern automobile manufacturing industry is constantly pursuing better performance and lower energy consumption, and improving the efficiency of gasoline engines has become an essential technical means.
