Are the Engine and Transmission the Same?

[VonSerenity]

Engine and transmission are not the same. The engine is the power source of a car. Most car engines are thermal power devices, referred to as thermal engines. The transmission changes the transmission ratio, expanding the torque and speed of the driving wheels. The car engine is the device that provides power to the car, serving as the heart of the car, determining its power, economy, stability, and environmental friendliness. Extension: Classification of transmissions: The transmission mainly refers to the car's transmission, which is divided into manual and automatic types. The manual transmission mainly consists of gears and shafts, achieving speed and torque changes through different gear combinations. The automatic transmission (AT) is composed of a torque converter, planetary gears, a hydraulic torque system, and a hydraulic control system, achieving speed and torque changes through hydraulic transmission and gear combinations.
