Interpretation of the model of Weichai low-speed high-torque engine
The engine is the heart of the vehicle and a steady stream of power is coming from here. The engine has a decisive effect on the overall performance of the truck, so the user pays more attention to the information of the engine carried by the vehicle when purchasing a car, and reading the engine model is an effective way to obtain engine information. Weichai Engine Exhibition As an important part of the domestic truck engine, the Weichai engine has now formed a full range of engine products that meet the National IV emission standards. Today, we have made a simple interpretation of the model of the Weichai engine to facilitate the purchase of cars. Weichai engine model naming rules Weichai trucks are rich in power products. At present, the National IV products are mainly based on the WP series. Weichai engines, which are widely used, are the stars of Weichai WP10.336E40 and are well known to the majority of heavy truck users. Today we will use this engine as an example to explain the meaning of a series of characters for the Weichai engine model. Weichai engine naming rules In this way, it looks like a series of letters and numbers will perform their duties at a glance. "WP" is the two initials of Weichai Power, Weichai Power English; "10" represents engine displacement; "NG" indicates that the engine fuel is natural gas, and "NG" indicates that the fuel is diesel; "336" is the horsepower value indicating the engine power; The meaning of "E4" is to meet the national IV emission standard; "0" indicates the product line. There are different types of small differences in performance Please pay attention to the last of the Weichai engine model. It may be the most unobtrusive one, and many people think it doesn't matter. However, the small differences in the engine model will also mean different structures and performance of the engine. If you notice this difference, it may help you choose the truck that better meets your needs. As can be seen from the chart, the four engines have the same displacement and rated power, but because of the slight differences in the numbers representing the product series, there will be some aspects such as the number of single-cylinder valves, the rotational speed at the rated power, and the maximum torque. different. The WP10 series engines E40 and E41 are single-cylinder and two-cylinder, while the E42 and E43 are single-cylinder and four-valve. Four-valve engines have higher intake and exhaust efficiency, better fuel efficiency, and engines with the same rated speed. It can be seen from the comparison of their maximum torque that the four-valve engine is more powerful. The WP10 series has two rated speeds of 1900rpm and 2200rpm, the E40 and E43 have a rated speed of 1900rpm, and the E41 and E42 have a rated speed of 2200rpm. At present, Weichai mainly pushes a low-speed engine with a rated speed of 1900 rpm. The low-speed engine can match the rear axle with a smaller speed ratio to improve transmission efficiency. At the same time, lower engine speeds can reduce engine component wear and extend engine life. This is also in line with the development trend of low-speed high-torque international heavy-duty engines. Whether an engine is good or bad depends on whether it can meet your needs, because the right one is optimal. Therefore, before you buy a car, you should be clear about the use of the vehicle and the required power level and cost factors, and select the truck that can meet the demand for use.
