1 Answers
Engine speed between 2000 RPM and 3000 RPM is the most fuel-efficient. The following are the specific requirements for the most fuel-efficient car engine: 1. RPM requirements: Engine speed between 2000 RPM and 3000 RPM is the most fuel-efficient. 2. Speed requirements: The speed of the car should be determined by the gear. Driving in fourth gear at 60 to 70 kilometers per hour is the most fuel-efficient, and driving in fifth gear at 80 to 90 kilometers per hour is the most fuel-efficient. 3. Road requirements: When the road is clear, try to choose the highest gear and maintain 3000 RPM. The vehicle's power performance can be improved, and the fuel consumption will be more ideal. The most fuel-efficient driving condition is to maintain the optimal speed and drive in a straight line at a constant speed.
