When the engine noise is reduced, the engine hood can isolate the heat generated when the engine works, effectively protect the paint on the engine hood surface and prevent aging.
Air shunt. For an object moving at high speed in the air, the air resistance and turbulence generated by the airflow around the moving object will directly affect the trajectory and speed. The shape of the hood can effectively adjust the direction of air flow relative to the car and the blocking force to the car, thus reducing the impact of air flow on the car. Through diversion, air resistance can be decomposed into beneficial forces.
Precautions:
(1) "Vehicle" refers to motor vehicles and non-motor vehicles.
(2) "Motor vehicle" refers to a wheeled vehicle that is driven or towed by a power plant and travels on the road for people to ride or transport articles and carry out special engineering operations.
(3) "Non-motor vehicles" refer to vehicles driven by human or animal power and running on roads, as well as disabled motorized wheelchairs, electric bicycles and other vehicles whose design maximum speed, no-load weight and overall dimensions meet the relevant national standards.
