Abstract

The invention provides a method and system for calibrating a transient fuel consumption meter. The method includes: acquiring all transient fuel consumption values of the transient fuel consumption meter within a preset time period through a controller, and weighing total consumed fuel flowing through the transient fuel consumption meter within the preset time period through an electronic scale; calculating a difference value between total fuel consumption corresponding to the sum of all transient fuel consumption values and the total consumed fuel through the controller; when the difference value exceeds a preset difference value, adjusting the transient fuel consumption value of the transient fuel consumption meter according to the difference value to acquire a display transient fuel consumption value to enable a display value of the transient fuel consumption meter to be within an error range so as to achieve the objective of calibration. In the process, only a data collection device and a weighing device are needed, so that calibration of the transient fuel consumption meter is completed simply and conveniently.

Description

technical field

[0001] The invention relates to the technical field of automobile detection, in particular to a calibration method and system for a transient fuel consumption meter. Background technique

[0002] At the vehicle inspection station, by using the fuel consumption meter to detect the change of the fuel consumption of the vehicle during use, not only the technical status of the fuel system, but also the technical status of the engine and the entire vehicle can be diagnosed. Although there are various fuel consumption meters at home and abroad at present, they all have their own deficiencies. Fuel consumption meters produced abroad have good performance and high reliability, but are expensive. Domestically produced fuel consumption meters have poor reliability and low measurement accuracy. Accurately detecting the fuel economy of a car can reduce the cost of using the car, save oil resources, and achieve the purpose of saving energy.
