What is the difference between an engine and a transmission?
1 Answers
The difference between an engine and a transmission lies in their distinct functions: The engine serves as the power source of a vehicle, with most automotive engines being thermal power devices, commonly referred to as heat engines. Relevant information is as follows: 1. Definition of a transmission: A transmission alters the gear ratio, expanding the torque and speed of the driving wheels. The automotive engine is the device that provides power to the vehicle, acting as the heart of the car and determining its power, fuel efficiency, stability, and environmental performance. 2. Classification of transmissions: Transmissions primarily refer to the vehicle's gearbox, which is divided into manual and automatic types. Manual transmissions mainly consist of gears and shafts, achieving speed and torque variation through different gear combinations. Automatic transmissions (AT) are composed of a torque converter, planetary gears, a hydraulic torque variation system, and a hydraulic control system, achieving speed and torque variation through hydraulic transmission and gear combinations.
