Performance and Emission Characteristics of Dimethyl Ether (DME) Mixed Liquefied Gas for Vehicle (LGV) as Alternative Fuel for Spark Ignition Engine

Liquefied Gas for Vehicle (LGV) is a derivative of Liquefied Petroleum Gas (LPG). DME is a new alternative to substitute LPG. LEMIGAS conducted research on LGV Mixed DME fuelled SI engine. The properties of blends with DME concentration in percent volume of 5%, 10%, 15%, and 20% were tested. Performance and Emission tests were done and compared with LGV and gasoline 91. The result showed that the power, torque, and acceleration decreased compare to LGV and gasoline 91. Fuel consumption is slightly increased. The CO and HC emission of blends are lower than referred fuel.
