| Abstract: | According to such properties of the dimethyl ether(DME) as high saturated vapor pressure,low viscosity and easy formation of mixture with air,a controllable premix combustion(CPC) low-pressure common rail fuel injection test bench of DME engine is developed.Based on this bench,contributing factors of fuel injection such as common rail pressure,needle lift and engine speed are analyzed during injection process.Hence,the characteristics of low-pressure common rail fuel injection are found; and it promotes the using of DME in low-pressure common rail system. |
