Oil injection angle correction method and device, electronic equipment and computer storage medium

Abstract

The invention provides an oil injection angle correction method and device, electronic equipment and a computer storage medium. The performance of the engine is improved. Comprising the steps that after it is determined that a calibrated engine is started, a pressure drop difference value is determined through a current air flow value of the calibrated engine; when it is determined that the pressure drop difference value does not meet the specified condition, an intermediate value is obtained according to the pressure drop difference value and a first preset standard value, the first preset standard value is used for representing the standard air inlet flow value in the calibrated engine, and the intermediate value is used for representing the rising degree or the falling degree of the air flow in the calibrated engine; determining an intermediate correction value corresponding to the intermediate value by using a preset corresponding relationship between the intermediate value and the intermediate correction value; obtaining a target correction value of the oil injection angle of the calibrated engine through the intermediate correction value and the current oil injection angle of the calibrated engine; and correcting the fuel injection angle of the calibrated engine based on the target correction value of the fuel injection angle of the calibrated engine.

Description

Technical field [0001] The present invention relates to the field of engine technology, and more particularly to a modified method, apparatus, electronic device, and computer storage medium of a fuel injection angle. Background technique [0002] When the gantry ECU (Electronic Control Unit, Electronic Control Unit) Data development calibration, the pressure drop loss of the mounted calorie is different from the pressure drop loss of the final vehicle installed, so that the engine gas is caused. Inconsistent, the engine fuel consumption is deteriorated and the exhaust gas is small, resulting in deterioration of the performance of the engine. Inventive content [0003] In an exemplary embodiment of the present invention, a modified method, apparatus, electronic device, and computer storage medium for optimizing the fuel consumption of the engine and improving exhaust emissions, and improving the performance of the engine. [0004] The first aspect of the present invention provide...

Problems solved by technology

[0002] During bench ECU (Electronic Control Unit, electronic control unit) data development and calibration, the pressure drop loss of the calibrated intercooler installed is different from the pressure drop loss of the intercooler installed in the final vehicle, so the engine intake air volume Inconsistency, poor engine fuel consumption and reduced exhaust emissions, resulting in poor engine performance
