Varbanets R. Diagnostic monitoring of marine diesel engine working process during operation

Methods of complex monitoring and analyzing of Diesel engines working process during its operation has been developed. Methods of division of examination functions and analytical method of data synchronization based on thermodynamic relations of working process has been developed. As result it has been able to simplify structure and to reduce hardware of the monitoring device. Such device allows monitoring and analyzing of ships Diesel engines during their operation. Developed methods have reduced costs of monitoring and increased its reliability making it affordable for wide variety of ships, transport and stationary Diesel engines. An adaptive mathematical model of working process has been developed using three-phase calculation of heat transfer. The model allows analyze efficiency of the engine operation in real time engine operation thus giving opportunity to estimate a possible maximum load and fuel consumption as well to find an optimal adjustment of the engine injection system and valve gear. A diesel engine performance analysing system has been developed which enables full examination of working process during the engine operation. The system software is based on methods which are described in this dissertation. The device has passed practical tests in several domestic and foreign shipping companies and it has been used by the Navy of Ukraine too.
