What do the three big cars mean

The engine is the heart of the car. It is responsible for converting fuel into power and passing it on to other components to keep the vehicle running properly. There are two engine types, naturally aspirated and turbocharged, and turbocharged engines are more energy efficient and powerful than naturally aspirated engines.

The chassis is the foundation of the car. It includes the braking system, the steering system, the Transmission system and the driving system to provide support and load for the car and ensure the safety of the occupants. In terms of braking system, if you use high-quality brake accessories, you can improve the braking effect and life. In terms of steering, the suspension is one of the key factors, providing a smooth driving experience. In terms of transmission system, there are two transmission modes: manual and automatic. In terms of the driving system, the tire is an important part, and the right tire can improve the stability, grip and life of the car.

The gearbox is the part that connects the engine and the wheels, converting the engine's speed and torque into the power output of the wheels. The Automatic Transmission is more suitable for urban driving than the manual transmission because it can automatically adjust the gear ratio according to different driving situations, improving fuel consumption and driving comfort.

The three major parts of the car are the engine, chassis and gearbox, which play a crucial role in the entire car. The selection of high-quality components can improve the performance and life of the car and ensure the safety of the occupants.
