What is the normal RPM when the engine just starts?
1 Answers
When the engine just starts, a normal RPM ranges between 1200 and 1500. The engine speed is related to the number of work cycles per unit time or the effective power output of the engine. That is, the effective power of the engine varies with different speeds. When indicating the effective power of the engine, the corresponding speed must also be specified. The effective power and its corresponding speed specified on the engine product nameplate are referred to as the rated power and rated speed, respectively. The rated power is not the peak power that the engine can produce but is the effective power usage limit set according to the engine's purpose. The peak torque output of an automotive engine and its corresponding speed serve as an indicator for evaluating the engine's dynamic performance.
