Does the tachometer 1 represent 1000 RPM?

[ReidDella]

The tachometer 1 represents 1000 RPM. The gauge with a red zone is the tachometer, which usually displays 1/minx1000. For example, when the needle points to 5, it means 5000 revolutions per minute. Generally, the RPM of household vehicles does not exceed 8000, while diesel engines usually operate at around 5000 RPM. Below is an introduction to the functions of the tachometer: 1. Displaying engine speed: RPM is a barometer of the engine's working condition. When the engine is idling or in neutral, the RPM should be stable and within a reasonable range. 2. Indicating potential engine faults: When pressing the accelerator pedal in neutral, the RPM should smoothly change with the pedal's movement. When the accelerator pedal is held steady, the tachometer needle should remain at a fixed RPM. If the engine idle speed is too high or too low, the RPM is unstable, or the tachometer needle fluctuates, it indicates a potential engine fault.
