What are the disadvantages of adding a seal strip to the engine hood?
1 Answers
Adding a seal to the car engine hood mainly affects the heat dissipation of the engine. This can lead to excessively high engine coolant temperature readings, prolonged operation of the electric fan at high speed, increased engine noise, and excessively high temperatures, with the most noticeable issues occurring when the air conditioning is on. Adding heat insulation cotton to the engine hood, from a thermal perspective, is essentially aimed at preventing heat from the engine or engine compartment from transferring to the hood, thereby protecting the paint on the hood surface. However, from a heat dissipation standpoint, it is important to dissipate the engine's heat to the outside as much as possible to achieve temperature balance. When radiant heat dissipation is obstructed, and the same amount of heat needs to be dissipated, the load on the fan for heat dissipation will inevitably increase. If the fan, even at maximum load, cannot effectively dissipate the heat, the temperature inside the engine and engine compartment will rise to achieve a new temperature balance. The engine hood is located at the front of the car, and the car engine is the engine itself. Depending on the vehicle's layout, the position of the engine compartment varies. For example, in cars with rear-mounted or mid-mounted engines, the engine hood is located at the rear of the car. The engine hood is a body cover panel and is not a structural component. Car cover panels include the engine hood, doors, front and rear bumpers, front fenders, and trunk lid. After removing all cover panels, what remains is the car body frame.
