What is the normal RPM when driving at 120 km/h?
1 Answers
When driving at 120 km/h, the normal engine RPM should be between 2000 and 3000. An engine only demonstrates its true advantages when operating above 2000 RPM. The RPM range of 2000 to 4000 is considered the healthy operating zone, where the engine can perform optimally. Engine RPM refers to the rotational speed of the engine, which determines the number of work cycles per unit time or the effective power output of the engine. The effective power of an engine varies with different RPM levels. Therefore, when specifying an engine's effective power, the corresponding RPM must also be indicated.
