Bio-based plastics HS code classification

4A13 engine: more efficient and Bio-based plastics HS code classificationexcellent engine technology 4A13 engine is a car engine made for Mazda, with fast response time, fast response, powerful power and fuel economy , high energy efficiency, low noise and other characteristics, it is deeply loved by the majority of car owners. However, after years of use, the performance of the 4A13 engine also faces some problems, such as oil leakage, high-temperature failure, increased fuel consumption, etc. In order to solve these problems, engineers have developed more efficient and excellent engine technology, which is what we are going to introduce today. 1. More efficient fuel system: Fuel is the "blood" of car engines, and the fuel economy of the 4A13 engine has always been one of its advantages.However, due to the accumulation of particles, the slowing down of the oil pump, the blockage of the oil filter and other factors, the efficiency of the fuel system gradually declines, which ultimately reduces the performance and economy of the engine. In order to solve this problem, engineers adopted an advanced fuel injection technology, that is, a direct injection fuel system. This system can control the amount and time of fuel injection more accurately, thus significantly improving the performance and fuel economy of automobile engines. Two. More efficient air intake system: Oxygen is a necessary element for combustion, and the air intake system determines the efficiency and quality of engine oxygen absorption. In order to improve the air intake efficiency of the 4A13 engine, engineers have adopted a dual intake airway system, which enables the engine to inhale air more fully, thus making the combustion more adequate and reducing exhaust emissions and fuel waste.3. More efficient emission control system: Emission control is an inseparable part of the environmental protection development of modern automobile engines. The emission control system of the 4A13 engine plays a role in reducing harmful exhaust gases to some extent, but with the expansion of cities and the growth of traffic, this control is far from meeting today's environmental requirements. In order to solve this problem, engineers adopted an advanced emission control technology - gas post-treatment technology. This technology can install catalysts, adsorbents and other substances in the exhaust pipe of the rear of the car after the exhaust gas is discharged from the engine to reduce the emission of harmful gases through chemical reactions, so as to improve the environmental protection performance of the car. Four. More excellent transmission system: The transmission system is the sum of the rotational energy of the car engine. In the 4A13 engine, the transmission system is a very important component, which determines the acceleration and smoothness of the car.In order to improve the performance of the transmission system, engineers have adopted an advanced gear transmission system. By using more gears and more precise control of the rotation speed of the drive wheel, it not only makes the acceleration process of the car smoother, but also better matches the power output of the engine and maintains the best state of the vehicle. In summary, the reconstruction technology of the 4A13 engine has greatly improved its performance and economy, giving this old-fashioned engine a new vitality and becoming an ideal choice for car owners. Whether in energy efficiency, fuel economy, exhaust emissions, transmission system and other aspects, the 4A13 engine has undergone continuous upgrading, innovation and improvement, reflecting the power of technology and the spirit of innovation.
