Abstract

The invention discloses an engine fuel injection quantity monitoring device and method. The method includes the following steps: S101 , collecting sensor data information of the engine; S102 , calculating and obtaining air flow according to the sensor data information, and searching for an air-fuel ratio intake flow MAP The basic fuel supply amount is obtained from the figure; S103, the ignition advance angle, the throttle valve opening and the air-fuel ratio are corrected according to various sensors; S104, the optimal fuel injection amount under a certain working condition is obtained. The present invention can accurately and quickly obtain the optimum fuel injection quantity of the engine, and provides data execution for the related debugging of the engine in the later stage, and the present invention has a simple structure and is easy to operate.

Description

technical field [0001] The invention relates to the field of engines, in particular to an engine fuel injection quantity monitoring device and method. Background technique [0002] An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines, external combustion engines, electric motors, etc. For example, internal combustion engines usually convert chemical energy into mechanical energy. The engine is not only applicable to the power generating device, but also refers to the whole machine including the power device. The engine is facing the dual pressure of development efficiency and development quality. The control of the engine fuel injection quantity is very important to the effect of the whole engine. How to quickly monitor the engine fuel injection quantity in the product development process is a difficult problem faced by all developers. However, a complete and effective monitoring device has not been for...
