Abstract
On the basis of brief analysis for cylinder pressure physical meaning, mechanism and sketch of electronic control based on cylinder pressure feedback was presented, pressure characteristic variable orienting to control was provided, cylinder pressure feedback has been obtained by means of polynomial fitting. Electronic control system with dual micro-processor based on MPC555 and DSP56F807 was designed, fiber-optical pressure sensor has been introduced to perform dynamic acquisition of cylinder pressure. Primary test on model 4100 diesel engine with high pressure common rail was made, testing result showed an availability of electronic control of common rail diesel engine based on cylinder pressure feedback.
