Problems solved by technology

[0004] In the existing technical solutions for engine state monitoring, only the supercharging pressure deviation can be judged in the range of all working conditions. In order to meet the full working conditions, a large fixed deviation threshold needs to be set, and it is difficult to realize real-time and accurate engine state monitoring. Monitoring and early warning, resulting in the inability to adjust the running state of the engine in time

Abstract

The invention discloses an engine control method and device, a storage medium and computer equipment, and the engine control method comprises the steps that the pressure deviation value of a manifold and the opening deviation value of an electric control pressure regulating valve are obtained; and the state of the engine is determined according to the preset interval where the pressure deviation value and the opening deviation value are located. The state of the engine is determined based on the preset interval where the pressure deviation value of the manifold and the opening deviation value of the electric control pressure regulating valve are located, different parameter threshold values are set according to different working conditions in the full working condition range, different levels of prompts are given, and therefore the state of the engine in the full working condition range is monitored.

Description

technical field [0001] The present invention relates to the technical field of equipment control, and in particular, to an engine control method, device, storage medium and computer equipment. Background technique [0002] With the higher power density of internal combustion engines, lower fuel consumption and increasingly stringent emission regulations, electronically controlled booster valves have obvious advantages in increasing exhaust temperature and improving plateau capability. [0003] In view of the current closed-loop control of engine boost pressure, if the engine pipeline is poorly sealed, the performance of the supercharger is cracked, etc., the engine power and emissions will be affected, so it is of great significance to monitor the engine status in real time. [0004] The prior art is aimed at the technical solution of engine state monitoring. In the range of all operating conditions, only the judgment of the supercharging pressure deviation is required. In o...
