Trade data-driven portfolio management

The Trade data-driven portfolio managementfront engine (the impact of the placement of the car engine on the performance of the vehicle) The placement of the car engine has a great impact on its performance and controllability. In the layout of the front engine, the engine is located at the front of the vehicle and arranged along the longitudinal direction of the vehicle. Compared with other layout methods, the layout of the front engine is the most common in the automotive industry.However, how does the layout of the front engine affect the performance and driving experience of the car? First of all, the layout of the front engine will affect the suspension structure of the car. Since the engine is located at the front of the vehicle, the layout of the front engine will cause the front of the vehicle to be heavy and the rear will be relatively light. Therefore, manufacturers need to make corresponding adjustments to the design of the suspension system to ensure that the vehicle has a balanced suspension force and stable maneuverability. Secondly, the layout of the front engine will affect the operability and controllability of the vehicle. Because the engine is located at the front of the vehicle, the front of the vehicle will become heavier, affecting the suspension system and the dynamic processing of the whole vehicle, which can make the vehicle's turning and violent movement more difficult, and also reduce the speed and acceleration performance of the vehicle. On the other hand, becauseBecause the center of gravity is biased to the front, front-engine vehicles are more likely to lose balance when driving and turning quickly. In short, the layout of the front engine usually causes the vehicle to feel a little clumsy in operation. Third, in terms of safety, the layout of the front engine is relatively safe. Because the engine and other important vehicle parts are located at the front of the vehicle, when the vehicle collides, the front engine can absorb the impact force and reduce the injury to the people in the car. In addition, for some material providers, the smaller space required in the rear of the car is also one of the factors affecting the layout of the front engine. If the rear of the vehicle needs enough space, the layout of the "front and rear" engine is a good choice, but this layout increases the total weight of the car and affects the dynamic processing performance. Fourth, the layout of the front engine has good support for the mechanical performance after mounting.Under the layout of the front engine, the engine and gearbox are not only placed at the front of the car, but also have a certain gap between them, which provides more choice for the suspension frame to adjust the shock absorption and driving performance. In addition, the layout of the front engine also contributes to the rear-drive design of the car, which is used in many performance models not only greatly improving their maneuverability and adaptability, but also increasing the fashion and brand image of their vehicles. To sum up, the layout of the front engine is the most common layout method in the automobile industry, which is mainly due to its safety and mechanical performance support function after mounting and other factors that have been widely recognized. However, it should be noted that for sports cars and racing vehicles, the limitations of the front engine are therefore more significant. In this case, another pioneering way of car engine layoutIt is applied to many racing vehicles - the layout of the middle engine, and we can read its relevant content in the relevant articles.
