What is the engine RPM at 60 km/h?
2 Answers
The engine RPM is approximately 1800 when the vehicle speed is 60 km/h. Here is an introduction to the high and low engine RPM conditions: 1. The engine RPM is related to the number of work cycles per unit time or the effective power output of the engine, meaning the effective power of the engine varies with different RPMs. Therefore, for a given effective power output, there is a corresponding optimal RPM. 2. When there is a sudden increase in RPM, it indicates a mismatch with the actual power output. At a certain speed, the ECU will provide an appropriate fuel injection quantity based on the collected data. The collected data generally includes throttle opening, water temperature, intake air volume, and other factors, which are comprehensively analyzed to determine the correct fuel injection timing and quantity.
For a typical manual transmission car, the RPM at 60 km/h depends on which gear you're in. In 3rd gear it might be around 2,500 RPM, dropping to about 2,000 RPM in 4th gear, and as low as 1,500 RPM in 5th gear is completely normal. Automatic transmissions are much smarter in their shifting logic - during smooth driving they generally maintain between 1,500 to 2,000 RPM. However, it's important to note that engines with different displacements behave quite differently; a 1.5L compact car and a 2.0T engine can show a 400-500 RPM difference at the same speed. Also, don't just focus on the gauge - engine sound is an important reference too. If the engine is revving above 3,000 RPM with noticeable noise, it's probably time to shift up.
