What is the Difference Between an Engine and a Transmission?
2 Answers
Transmissions and engines mainly have the following differences: 1. The transmission changes the gear ratio to expand the torque and speed of the drive wheels. 2. The engine is the power source of a car. Most car engines are thermal power devices, referred to as heat engines. Below are related introductions to transmissions and engines: 1. The transmission mainly refers to the car's gearbox, which is divided into manual and automatic types. Manual transmissions primarily consist of gears and shafts, achieving speed and torque changes through different gear combinations. 2. The car engine is the device that provides power to the car, serving as the heart of the vehicle. It determines the car's power, fuel efficiency, stability, and environmental friendliness.
I've been driving for over 20 years and have experienced various types of engines and transmissions. The engine is the source of a car's power, burning gasoline or diesel to generate rotational force, just like a heart providing the energy to move the vehicle. The transmission is the key component that transfers this power, using gear sets to adjust speed and torque, allowing smooth acceleration and deceleration in different road conditions. For example, in city traffic jams, an automatic transmission shifts gears effortlessly, while a manual transmission requires me to press the clutch and shift gears to control speed. Without a transmission, the engine would directly drive the wheels, making it prone to stalling at startup due to excessive force, and causing the engine to rev too high at speed, leading to increased fuel consumption and faster wear. Regular maintenance is crucial: engine oil should be changed every 5,000 kilometers, and transmission fluid every 60,000 kilometers. Neglecting these can result in rough shifting or unusual noises. In electric vehicles, the transmission is simplified to a reducer, but it serves the same purpose of adjusting power output, with slightly simpler maintenance. In summary, the engine provides the power, and the transmission manages its distribution—both are indispensable.
