Where is customs transaction analysisthe car engine (where is the position of the car engine?) As a modern means of transportation, cars are undoubtedly the most common choice in our daily travel. One of the most daily key parts of a car must be the engine. So, where is the car engine? Where is the position of the car engine? This article will give you a detailed answer. I. The basic position of the engine is that the car engine is mostly distributed at the head of the vehicle. For safety's sake, 86% of the car engines are under the front hood, which strictly follows the safety principles such as approaching the center of gravity, improving vehicle stability, increasing traction, and reducing the load distribution of front and rear wheels.The same is true for the front engine of the car. The engine temperature is relatively high, and the exhaust gas is emitted. It is placed more in the front of the vehicle to ensure that the air in the vehicle is fresh, and it is also easy to treat the exhaust gas. II. The subdivision position of the engine 1. In the front-wheel drive model, the engine is close to the part where the driver and the passenger sit, and the heat dispersion and control accuracy are relatively good. The disadvantage is that once an accident occurs, the engine may rush into the carriage and endanger the passengers. Two. The engine of the front and rear-wheel drive model is behind the front axle, and the relative possibility of escaping from the front of the vehicle is greater, but in the same way, there are also some difficulties for precision control. 3. The middle rear-wheel drive model The middle rear-wheel drive model is placed between the center of gravity of the vehicle, and the center of gravity of the engine and center of gravity is sitting. The balance and controllability of the vehicle are the same.For the more prominent, the disadvantage is that more space is needed between the engine and the rear wheel, and the body angle and size must be designed more innovatively to adapt to the nature of the car. Four. The rear-wheel drive model rear-drive engine was originally popular in luxury sports car dealers such as Porsche, and also appeared in many cars of Volkswagen and other car dealers. This design allows the engine carried by the vehicle to be located behind the wheel. III. Why should the engine be placed in the front? In terms of safety, by placing the engine at the front of the vehicle, the vehicle's center of gravity can be moved forward, the vehicle can be better controlled, and the weight distribution of the vehicle can be better balanced. Ensure the long-term stability of the vehicle by placing most of the weight on the front. At the same time, the design and layout of some modules such as cooling and transmission systems and fuel management in which the engine participates also needs to consider the rationality of the design.If the engine is at the rear of the car, the pipes and links that supply mechanical fluids will become longer, which is prone to problems such as damage and aging of the pipes. IV. Knowledge points brought to us by the engine 1. In addition to being divided into front, middle and rear engines, safety and protection also need to be specially considered. Two. The engine has a heat problem in the car, and the heat dissipation and sewage system need to be considered. 3. The system layout of car fuel management and air collection of the same brand is also different, and the components should be identified according to the model and brand of the car you buy. Four. It is very important that the battery and engine should be checked regularly to get the best results and performance.
