The three major components of a car are: engine, transmission, and chassis. The function of the engine is: to convert the thermal energy of gasoline or diesel into mechanical energy by burning and expanding the gas in a sealed cylinder, thereby pushing the piston to perform work. The function of the transmission is: to change the transmission ratio, expand the range of torque and speed changes of the driving wheels, adapt to frequently changing driving conditions, and allow the engine to operate under favorable working conditions. The function of the chassis is: to support and install the car engine and its various components and assemblies, form the body shape, receive the power from the engine, enable the car to move, and maintain normal driving.

When I was learning to drive, my instructor always mentioned that the three major components of a car are the engine, chassis, and transmission. The engine is like the heart of the car, responsible for generating power to make the car move; the chassis includes parts like the suspension system and wheels, supporting the entire body to maintain stability; the transmission controls speed changes, and whether it's manual or automatic affects driving smoothness. Knowing these makes maintenance easier, such as regularly checking the engine oil and chassis shock absorbers, and ensuring timely transmission fluid changes. When driving, if the engine feels powerful, fuel consumption is well controlled; with a good chassis suspension, cornering becomes safer; and a smooth transmission prevents frequent jerking, significantly improving the driving experience and extending the car's lifespan.

During the use of the car, if any electrical equipment is not working, it may be caused by a blown fuse and needs to be replaced in time. The fuse box is an overcurrent protection switch, whose main function is to control the working power of the circuit. The key role of the fuse is to protect the circuit from damage caused by excessive current. According to the type, it can be divided into fast-acting fuses and time-delay fuses. Fast-acting fuses are designed to quickly break the circuit in response to temporary surge currents, while time-delay fuses are used for buffering and delaying when starting large currents.
