What is the most fuel-efficient engine RPM for a car?
1 Answers
Each car has its own economical RPM range. Here is some information about car RPM: 1. According to the law of energy conservation, the less fuel consumed, the less work is done, which also applies to the automotive industry. In the most fuel-efficient state, the power output is weaker, and of course, the speed won't be too fast. Therefore, to determine the most fuel-efficient RPM, we need to analyze it under low-speed conditions. 2. Currently, there are two mainstream types of engines in the domestic market. One is the small-displacement turbocharged engine, represented by the 1.5T, and the other is the larger-displacement naturally aspirated engine, represented by the 2.0L. These two types of engines have their own different economical RPM ranges. 3. Take a manual transmission car as an example. Of course, you need to be in the highest gear. While ensuring no jerking or shaking, try to reduce your speed. When the engine starts to shake, press the accelerator, and the RPM after pressing the accelerator is the economical RPM. For example, if a car is in fifth gear and the engine slightly shakes at 1400 RPM, indicating the need to downshift, but after pressing the accelerator, the RPM rises to 1600 RPM without shaking, then the economical RPM for this car is 1600 RPM. The same logic applies to most manual transmission cars. 4. To some extent, maintaining a high gear and low RPM without causing engine shaking or jerking is the most fuel-efficient. If the car has cruise control, after driving for a certain distance, the combined fuel consumption will be lower than the official fuel consumption.
