Why is the hood of a new car very hot?

1 Answers

Because the heat dissipated by the engine accumulates on the hood. The following is relevant information about the hood: 1. Introduction: Made of rubber foam and aluminum foil materials, it reduces engine noise while isolating the heat generated during engine operation, effectively protecting the paint on the hood surface and preventing aging. 2. Function: Airflow diversion. For objects moving at high speed in the air, the air resistance and turbulence generated by the airflow around the moving object directly affect its trajectory and speed. The shape of the hood can effectively adjust the direction of the airflow relative to the car's movement and the resistance force it generates, reducing the impact of airflow on the car. Through diversion, air resistance can be decomposed into beneficial forces, increasing the force of the front tires on the ground, which helps stabilize the car's movement. The streamlined appearance of the hood is basically designed based on this principle.

How long should a car warm up before starting?

Car warm-up before starting can be done within 30 seconds to one minute after ignition. Below are the daily maintenance and operational precautions for vehicles: Daily vehicle maintenance: Regularly change engine oil, replace the three filters (air, oil, and fuel), and periodically add power steering fluid, brake fluid, and coolant. Frequently monitor and check the condition of engine oil, brake fluid, and antifreeze. Additionally, keep the engine clean by regular washing. Driving precautions: When starting a cold engine, allow the car to idle for about one and a half minutes to give it sufficient warm-up time. Extend the engine shutdown by half a minute after parking. The engine remains at a high temperature after stopping; shutting it off immediately causes the cooling fan to stop right away, which is not conducive to engine cooling.

Here are some precautions during the break-in period of a new car: Avoid high-speed driving: Try not to let the car's speed reach 120km/h, as this can help maintain the engine's performance and prolong its lifespan. Avoid overloading: Placing overweight objects in the car during the break-in period undoubtedly puts pressure on the vehicle. Overloading often requires frequent gear changes, and the constant shifting between high and low gears can be very detrimental to the engine. Avoid driving on extremely poor road conditions: Driving on very rough roads during the break-in period causes significant wear to the tires. Moreover, prolonged driving under such conditions forces the engine to operate at high power continuously, which is bound to cause damage.

What Causes the Abnormal Noise When a Car Reaches 90 to 100 km/h?
