Abstract

The invention discloses a system and a method for proofreading electric control data of a diesel engine. According to the system provided by the invention, a standard data editing module is used for establishing, editing and configuring a standard data file, a data analysis module is used for introducing the standard data file from the standard data editing module and analyzing proofread variable information in electric control calibration data and standard information in the standard data file, and a data proofreading module is used for introducing the standard data file and a proofread variable from the data analysis module to proofread, and transmitting the proofreading result to a proofreading report generating module to generate and display a proofreading report. The method provided by the invention comprises the following steps: establishing, editing and configuring the standard data file by the standard data editing module, analyzing proofread variable information and standard information in the standard data file by the data analysis module, proofreading three attributes, that is to say, range, monotony and reasonability of the proofread variable by the data proofreading module, and transmitting the proofreading result to a proofreading report generating module to generate and display a proofreading report.

Description

technical field [0001] The invention relates to the field of electronically controlled diesel engines, in particular to a diesel engine electronically controlled data proofreading system and a proofreading method. Background technique [0002] An electronically controlled diesel engine is an engine that controls conditions such as fuel injection quantity and fuel injection time through an electronic control unit. The electronically controlled diesel engine takes the engine speed and load as the basic signals reflecting the actual working conditions of the diesel engine, and determines the basic fuel injection quantity and injection timing map by referring to the fuel injection quantity and fuel injection timing map corresponding to each working condition of the engine obtained from the test. Oil time, etc., and then make various compensations according to various factors (such as water temperature, oil temperature, atmospheric pressure, etc.) to obtain the best working state...

AI Technical Summary

Problems solved by technology

[0006] There are many models of electronically controlled diesel engines, and each model uses a specific set of calibration data. Each model is divided into National III emission standards and National IV or even National V emission standards. The same emission standard has different consequences. At the same time, the same model will be distinguished according to its different uses. A set of calibration data has thousands of calibration variables. The workload of proofreading is very large, and multiple engineers need to work together to complete a set of calibration data. Proofreading of sets of data, the efficiency of proofreading is very low;

[0007] Secondly, manual proofreading requires proofreading engineers to be patient and careful. Faced with a huge and boring workload, it is inevitable that proofreading errors will occur, and the proofreading effect cannot be guaranteed
