What is the normal engine speed for a car?

[LaCorey]

Car engine speed is normally between 700 and 800 revolutions per minute (RPM). Car engine speed refers to the rotational speed of the car's engine, and its functions include: 1. Reflecting the engine's operating condition in real-time; 2. Helping drivers better coordinate with the transmission gear and throttle position; 3. Maintaining the car in an optimal working state; 4. Reducing consumption and extending the engine's lifespan. The significance of engine speed lies in the fact that it determines the number of work cycles per unit time or the effective power output of the engine, meaning the engine's effective power varies with different speeds. An engine is a machine that converts other forms of energy into mechanical energy, and it can be categorized into: external combustion engines, internal combustion engines, gas turbines, and jet engines.
