In this study, DME-blended LPG fuel was experimentally investigated in CI(compression ignition) engine. In particular, performance, emissions characteristics (including hydrocarbon, CO, and NOx emissions), and combustion stability of engine fuelled with DME-blended LPG fuel were examined. LPG fuel was blended to DME fuel by LPG 0-40wt%, Results showed that stable engine operation was possible for a wide range of engine loads up to 30% of LPG by mass in a CI engine. Considering the results of the engine power out put and exhaust emissions, blended fuel up to 30% of LPG by mass can be used as an alternative to diesel in a CI engine. DME blended LPG fuel is expected to have potential for enlarging the DME market.
세탄가를 向土시킨 LPG 戰料의 壓縮着火 디젤 엔진의 性能및 排出가스 特性에 關한 硏究

In this study, a feasibility test of liquefied petroleum gas (LPG) direct injection (DI) compression ignition engine has been carried out to study the effectiveness of cetane enhancing additive; Di-tertiary-butyl peroxide(DTBP) Performance and emissions characteristics of a diesel engine fuelled with LPG and DTBP blended fuel were examined Results showed that stable diesel engine operation over a wide range of the engine loads was possible. Estimated cetane number of the LPG with a 15 wt% DTBP was more than 55 suggesting the possibility of utilizing LPG as a DME(dimethyl ether). Exhaust emissions measurements showed that hydrocarbon was decreased with the blended fuel at enhancing cetane number. Furthermore, the combustion stability of LPG with a cetane number improver was comparable to DME fuel. Considering the results of engine performance and exhaust emissions, LPG blended fuel of enhancing cetane number could be used as an alternative fuel for diesel.
