Analysis of the impact of engine layout on Global trade supply chain modelingautomobile performance Engine layout refers to the position and direction of the engine in the body, mainly including three layouts: front, middle and rear. Different layout methods will have different effects on the performance of the car. Let's analyze it in detail. 1. Front engine layout Front engine layout refers to the layout of the engine located at the front of the vehicle. This layout is the most common and widely used in medium and low-end cars. Because the engine weight is concentrated in the front, models with front engines are usually susceptible to the inertial force when steering.At the same time, because the engine is close to the front of the car, the weight of the front of the vehicle is very concentrated, so the stability of the car is poor when driving at high speed, and it is easy to collide or break down. However, the advantages of the front engine layout are also obvious. First of all, because the engine occupies the front of the car, the space at the rear of the car is relatively large, so functions and equipment for seats, luggage and passenger comfort can be easily installed in the rear. Secondly, because the engine is directly connected to the transmission shaft, the power generated by its power is easy to be transmitted to the rear wheel, which improves the performance and sensitivity of the vehicle. Two. Central engine layout Central engine layout refers to the layout of the vehicle engine in the middle of the body. The advantage of placing the engine in the center is that it can effectively reduce the center of gravity of the vehicle, improve the handling performance and driving stability, and alsoIn order to better balance the front and rear weight ratio of the car, the momentum when reducing the inertia of the vehicle will be smaller, and the turning will be more flexible and more stable. The disadvantages of the middle engine are also obvious. First of all, because the engine is located in the middle of the body, it brings more difficulty to the internal mechanism of the vehicle, which consumes more money and time. Secondly, because it is difficult for large engines to pass the certification of regulations and standards, this layout is rare in daily models. 3. Rear engine layout Rear engine layout refers to the way the engine is located at the rear of the vehicle. As a luxury brand of Rolls-Royce, Porsche, etc., it reflects its characteristics and inheritance. The advantage of this layout is that it can improve the lightness of the second half of the vehicle, enhance the feel feedback and sports style, and eliminate the center of gravity shift. In addition, because the engine is rumblingThe crisp sound is deeply loved by enthusiasts of different ages, and it is also one of the reasons why many car fans choose this layout. However, the rear engine layout also has its own shortcomings. Because the engine is installed in the rear of the car, the space in the car is limited and it is difficult to place large suitcases. In addition, in the second-hand market, due to the rear engine, the value preservation ability of the model is more unstable than that of vehicles with front engine. Generally speaking, the layout of the engine has a significant impact on the performance of the car. The front engine is relatively balanced, the middle engine is difficult to handle, and the rear engine allows the driver to experience a sense of coquettish superiority. When buying a vehicle, according to your own needs and driving style, the advantages and disadvantages of any engine layout need to be measured in combination with the use environment to obtain the best performance and comfort.
