A Complete Collection of Automotive Fundamentals
1、 System knowledge
1. A car is a non track vehicle that is driven by its own power unit and has 4 or more wheels.
2. Passenger cars are mainly used for carrying passengers, their carry-on luggage, and/or temporary items in their design and technical characteristics, including the driver's seat, with a maximum of 9 seats.
3. The engine is the power unit of a car, consisting of two major mechanisms and five major systems: crank linkage mechanism, valve distribution mechanism, cooling system, fuel supply system, lubrication system, ignition system, and starting system. However, diesel engines have one less ignition system than gasoline engines.
4. The braking system of automobiles can be divided into manual braking system, power braking system, and servo braking system.
2、 Use common sense
1. The use of air conditioning: Car air conditioning is mainly divided into three parts: wind direction, wind speed, and temperature.
2. The use of internal circulation: Internal circulation refers to the state of air circulation inside the car. If the external air is poor, internal circulation should be used. In the summer, internal circulation should be used.
3. Car wash solution should be noted: Do not rinse vehicles that are exposed to sunlight with cold water. The surface temperature of the car paint is very high when vehicles are exposed to prolonged sun exposure during the summer. At this point, if the car is washed and the paint comes into contact with cold water, the skin will become dull, causing heat expansion and contraction, which can easily damage the paint.
4. Car tires: The normal lifespan of a car tire is three to five years, even if it is driven less frequently, it is still necessary to replace the tire in a timely manner after exceeding its lifespan.
5. Regarding tire punctures: tire pressure should be constantly monitored, avoiding sudden acceleration and various intense driving. If tire pressure is abnormal, it is necessary to find a safe place to replace it.
