What does car fuel consumption mean?
1 Answers
Car fuel consumption refers to the amount of fuel consumed by a vehicle when traveling 100 kilometers. Fuel consumption includes constant-speed fuel consumption and road cycle fuel consumption: 1. Constant-speed fuel consumption: This is a fuel economy indicator when a car travels at a constant speed on a good road surface. The constant-speed fuel consumption at 90Km/h and 120Km/h serves as the main evaluation criteria for fuel economy. The fuel consumption per 100 kilometers indicated in the manuals of domestic cars is generally constant-speed fuel consumption. However, since cars often experience various working conditions such as acceleration, deceleration, braking, and engine idling during actual driving, constant-speed fuel consumption is often lower and differs significantly from actual fuel consumption. 2. Road cycle fuel consumption: This is a fuel economy indicator measured when a car travels repeatedly on the road according to specified speed and time specifications, also known as multi-condition road cycle fuel consumption. The Society of Automotive Engineers (SAE) in the United States has established the SAE J10926 road cycle test specification, which is widely adopted. This specification includes four different cycles: urban, suburban, interstate (55Mile/h), and interstate (70Mile/h).
