An idea of Combustion Process Onboard Monitoring System — CPOMS for multi-cylinder engine

Abstract

In this paper conception of combustion process monitoring system is proposed. The system based on pressure sensor mounted on one of combustion engine cylinders. Due to cost reduction and additionally allowing analysis of operating cycles of each others engine cylinders an introduction of high resolution rotational sensor is proposed. In this paper a conception and initial research of Combustion Process Onboard Monitoring System (CPOMS) on CI engine are presented. Application of algorithm which merged information included at cylinder pressure signal with analysis of rotational speed course during operating cycles of each cylinders allow to control the engine fuel feeding system, air supply, EGR operating and others. The additional information about combustion process in each cylinder allow to control of engine operating conditions and as a result improvement of engine operating indexes. In this paper is also proposed modification of system elements as rotational/ positioning sensors proposed.
