Abstract

Embodiments of the present invention provide a method and device for measuring fuel consumption, and a fuel tank. The method includes: obtaining the first oil level of the fuel tank to be tested at the initial moment of measurement and the second oil level at the end of the measurement; respectively inputting the first oil level and the second oil level into preset The flow correction model for the first cumulative flow corresponding to the first fuel volume height and the second cumulative flow corresponding to the second fuel volume height are obtained; wherein, the flow correction model is for the fuel tank to be tested The historical flow data is obtained by performing preset data correction training; according to the first cumulative flow and the second cumulative flow, the fuel consumption between the measurement initial time and the measurement termination time is obtained. The embodiment of the present invention solves the problem in the prior art that the fuel consumption meter is likely to cause inaccurate measurement of the fuel consumption.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a method and device for measuring fuel consumption, and a fuel tank. Background technique [0002] Fuel consumption is an important parameter to characterize engine performance. Fuel consumption usually includes two types: Constant-Speed ​​Fuel Economy and Fuel Economy of Chassis Dynamometer TestCycles. [0003] Specifically, the fuel consumption at a constant speed refers to the fuel economy index when the vehicle is running at a constant speed on a good road surface. Because constant speed driving is a basic working condition for vehicles running on the road, and this kind of fuel consumption is easy to measure, it is widely used. For example, France and Germany put 90Km / h (km / h) and 120Km / h Constant fuel consumption is the main evaluation index of fuel economy. However, because the vehicle often has various working conditions such as acceleration, deceleration, braking, and...
