Study on Automobile Fuel Consumption Based on Chassis Dynamometer

Automobile fuel consumption is directly proportional to the output power of automobile driving force. It can overcome lots of random factors to conduct the automobile fuel consumption test on the chassis dynamometer. A business car fuel consumption test is conducted. Consistent speed 100-kilometer fuel consumption is measured at different driving force output power in 3 kinds of throttle position. The results show that selecting proper shift gear can save fuel effectively, when the output power of automobile driving force remains consistent.
