Cross-border HS code harmonization

Reconstructing the engine line to improve engine efficiency The Cross-border HS code harmonizationengine is an important part of the car. It provides the power and traction required by the car. The efficiency of the engine directly affects the performance and economic performance of the car, so improving the efficiency of the engine has become an important goal of automobile manufacturers. Reconstructing the engine circuit is one of the core ways to improve engine efficiency. Disadvantages of the traditional engine circuit The traditional engine circuit consists of four steps of exhaust, intake, compression and explosion caused by round-trip pistons, but its efficiency has many disadvantages.: I. High energy consumption: Because the energy waste of the traditional engine line is very serious, it cannot make full use of gasoline energy, resulting in an increase in fuel consumption, which makes the power efficiency of the traditional engine line not very high. II. Multiple oil supply: Due to the fixed size and shape of the cylinder of the traditional engine line, blind multiple oil supply may sometimes make the cylinder too much and too little, which is easy to lead to a reduction in engine power. III. Excessive emissions: Due to the generation of exhaust gas and the traditional engine lines, it is not conducive to further reducing engine emissions, especially the emissions of particulate matter and nitrogen oxides. The principle of reconstructing the engine circuit In order to solve the disadvantages of the traditional engine circuit, automobile manufacturers have developed a new type of engine circuit - Dual-Mode Cycle Engine (DMCE).The core of DMCE is to apply two different cycle modes to automobile engines to achieve higher efficiency and lower emissions. The first cycle mode of DMCE is the throttle valve direct oilization (DSEC) technology. Its main feature is to expand the opening range of the throttle valve and continuously spray gasoline into the engine cylinder through advanced technologies such as larger valves and biodiesel. In this way, the mixing of air and oil can be reduced, and the oil spray can be wrapped in a layer outside the air, thus improving the thermal efficiency of fuel and reducing the waste of fuel. Another cycle mode is called compression ignition (CCI) technology, which adopts a special combustion chamber design to achieve more efficient combustion under a reasonable compression ratio, greatly improve thermal efficiency and reduce emissions.DMCE enables the engine to work in different states through these two different cycle modes, thus achieving higher efficiency and lower emissions. And its core mechanism is two intake channels of different sizes, which correspond to the two cycle modes of DSEC and CCI respectively. Advantages of reconstructing the engine line. Compared with the traditional engine line, the engine using DMCE technology has many advantages: First, high thermal efficiency: DMCE technology can fully burn the fuel, greatly improving the thermal efficiency of the engine and reducing the fuel consumption rate. II. Low emission: DMCE technology can also reduce emissions, optimize the emission performance of the engine, and reduce the emission of harmful gases and particulate matter while ensuring higher power and torque output, which meets modern environmental protection requirements. III. Strong scalability: DMCEThere are many technical models and can make feasible trade-oms according to the actual application needs, integrate the characteristics of various power systems for global optimization, and have a wide range of adaptability and scalability. IV. Strong safety: The application of DMCE technology can make the engine work more smoothly, reduce the dangerous factors when driving, and improve driving safety. Conclusion Reconstructing the engine circuit can effectively improve the efficiency of the engine, which meets the development requirements of "low consumption, low emission, high efficiency and high performance" in the modern automobile manufacturing industry. DMCE technology can enable the engine to achieve high thermal efficiency and low emission at the same time, and also has the advantages of scalability and strong safety, and its application prospects are unlimited.
