摘要

The aim of this study was compared the spray characteristics of a typical fuel(100% Diesel, DME) and Diesel-DME blended fuel in Constant Volume Combustion Chamber(CVCC). typical fuel(100% Diesel, DME) and Diesel-DME blended fuel spray characteristics were investigated about varied ambient pressure(Pressurized nitrogen) and fuel injection pressure using the common rail fuel injection system when the fuel mixture ratio is varied. The fuel injection quantity and spray characteristics were measured, the spray characteristic research parameters were spray shape, penetration length, and spray angle, common types of injectors were used(bosch).
