液化石油气汽车排放的试验研究

Experimental Study on Emission of Liquefied Petroleum Gas Vehicles

液化石油气作为汽车燃料有利于能源的多样化并能降低汽车尾气排放 在发动机台架上对经减少烯烃处理后的三种组分车用液化石油气进行试验 ,并在整车上对多种蒸发器进行测试 ,实验结果表明 ,怠速排放低于原发动机 ,加装电控和三效催化装置后排放满足ECER83 0

Liquefied petroleum gas (LPG),as a fuel for vehicles, can reduce the exhaust emission of vehicles. It also provides energy diversities for vehicles. On engine testing bench, three kinds of LPG, with reduced proportion of alkene, are tested. A few evaporators are also tested on the whole vehicles. The experiment shows that the emission at idle condition is lower than that for the original engine and meets ECE-R83/01 standard after installing electronic control system and catalytic agent.
