What does automatic transmission mean?

[DiAriana]

Automatic transmission, commonly known as the automatic gearbox, refers to a system where the driver does not need to manually shift gears. Below is an introduction to automatic transmission: 1. Principle of operation: The engine's power is transmitted through the gearbox, which is also a key factor affecting fuel consumption. Generally, automatic transmissions consume 10% more fuel than manual transmissions. Whether manual or automatic, more gears mean better fuel efficiency. 2. Driving techniques: For manual transmission vehicles, it is advisable to shift gears at higher RPMs. Engines are designed to operate at higher RPMs, with parameters like dynamic balance and rotational inertia optimized for such conditions. If the engine operates for extended periods at non-optimal RPMs, internal components experience increased load and wear, leading to vibrations and knocking, which can shorten the engine's lifespan. Shifting at around 3000 RPM ensures that the engine operates within a healthy RPM range post-shift, typically around 2300 RPM.
