Diesel Combustion Improvement Using High Boost, Wide Range and High Rate EGR in a Single Cylinder Engine (Third Report)

The authors utilized pre- and post-injection to split the heat release for decreasing peak cylinder gas temperature as a strategy. The experiments were conducted in a single cylinder diesel engine for heavy-duty use and operated at BMEP = 0.8 MPa of middle load. The injection timings and quantities of each injection events were changed as parameters. As a result, a multi-injection pattern simultaneously reduced exhaust emissions and fuel consumption and improved the nozzle optimization. The flame movements of the multi-injection in cylinder were observed by means of a high-speed camera and a bore scope.
