Why is the fuel consumption gauge fluctuating erratically?
1 Answers
Average fuel consumption is a calculated value used to display the fuel consumption over a certain distance traveled. During driving, significant changes in external air temperature or unstable engine coolant temperature can cause the computer to fluctuate greatly in calculating the fuel injection volume, leading to constant erratic fluctuations in the average fuel consumption gauge. Relevant information about fuel consumption is as follows: 1. Introduction: Fuel consumption generally refers to constant-speed fuel consumption, which is the vehicle's fuel consumption per 100 kilometers obtained in the constant-speed driving fuel consumption test specified by national standards for certain types of vehicles. 2. Testing method: The test can be conducted on the road or on a chassis dynamometer, and then the fuel consumption per 100 kilometers is calculated using the "flow meter method" or "carbon balance method."
