What is the appropriate engine speed for normal driving?
2 Answers
Normal driving engine speed is appropriate at 700 to 800 RPM. Engine speed refers to the rotational speed of the car engine, and its functions are: 1. To promptly reflect the operating condition of the engine; 2. To allow the driver to better coordinate with the transmission gear and throttle position; 3. To keep the car in a better working state; 4. To reduce consumption and prolong the engine's lifespan. The significance of engine speed is: The level of engine speed is related to the number of work cycles per unit time or the size of the engine's effective power, meaning the engine's effective power varies with different speeds. The tachometer is set in the instrument panel, symmetrically placed with the speedometer.
When driving in the city for daily commutes, I think maintaining an engine speed between 1500 and 2500 RPM is quite okay. It mainly depends on your car model and driving habits: for automatic transmission cars, the gear shifts automatically, and the RPM usually stabilizes around 2000, which is fuel-efficient and comfortable; for manual transmission, if you shift gears promptly, the RPM won’t jump too high. During highway cruising at speeds of 80-100 km/h, the RPM may drop to around 1500, making the engine quieter and more fuel-efficient. The key is to follow your driving feel—avoid keeping the RPM consistently above 3000 or below idle speed, as this can cause the car to shake or wear out faster. My advice is to monitor the tachometer on the dashboard; driving gently in daily conditions is better for the engine and saves fuel costs.
