CDF simulation-based research of influence of mechanical defects in nozzles on environmental parameters of automotive diesel engines

The article considers whether it is possible to continuously monitor the technical condition of vehicles in operation without significant changes in their design. We analyze a list of faults and parameters to be controlled to ensure continuous monitoring of the technical condition of Isuzu 4FH1 diesel engine supply system elements. The results of simulating the fuel injection process using Star-CCM+ software are presented. The results of an experimental analysis of crankshaft position sensor readings confirming the simulation results are presented as well.
