Work process control mechanisms of diesel engine

Abstract

The article discusses the issue of reducing the specific fuel consumption and improving the environmental performance of internal combustion engines by changing the working process to obtain high-quality and timely heat release as a result of fuel combustion. The purpose of workflow control is to create favorable conditions for fuel ignition. The ways of occurrence of ignition centers in the combustion chamber are considered. The main periods of fuel supply, the duration of ignition depending on the lag time, the combustion process, the influence of the fuel supply advance angle on the environmental parameters of the engine are highlighted. The possibility of controlling the working process during the preparation of the beginning of combustion is substantiated and examples of mechanisms of domestic and foreign analogs that provide control of the working process are given. Conclusion - high performance management of the workflow is provided by the electronic control system - common rail, despite the widespread use of mechanical methods.
