Study on cold starting performance of a low compression ratio diesel engine by using intake flame preheating
Power density improvement is one the main techniques for engine thermal efficiency promotion. For turbocharged Diesel engine, low compression ratio in normally adopted for safety consideration under high power density operation. However, low compression ratio tends to lead cold starting problem. In...

| description | Power density improvement is one the main techniques for engine thermal efficiency promotion. For turbocharged Diesel engine, low compression ratio in normally adopted for safety consideration under high power density operation. However, low compression ratio tends to lead cold starting problem. In this study, the influences factors and performances of a 10-cylinder turbocharged Diesel engine was investigated. An intake flame preheating model was built and validated by series of bench tests. The optimization of starting parameters and flame heating was conducted eventually. Based on the study, the basic performance flame pre-heating system under different conditions was disclosed. The cold starting boundary parameters of the Diesel engine was found. Moreover, the best starting fuel injection parameters were acquired. The research is beneficial for Diesel engine power density promotion based on cold starting ability
