以液态石油气为燃料的发动机的合成排放消声器设计原理

可使用两种燃料的发动机,指既可使用汽油也可使用另一种燃料的发动机。分布最广泛的代用燃料是由石油和含高浓度丙烷成分的天然气混合而成的液态石油气(LPG)。它的炼制成本较低,许多国家并没有对它征收如汽柴油一样的附加税,因而得到消费者青睐。本文设计了同时兼有控制液态石油气燃气发动机燃气排放和噪声的合成排放消声器,主要应用于受尺寸限制的材料装卸、搬运车上。

Compact Design of Catalyst Muffler for Engines Using Liquefied Petroleum Gas

Dual-fuel engine can run on either gasoline or another fuel.The most widespread alternative fuel is Liquefied Petroleum Gas(LPG),which is a mixture of petroleum and natural gases of high propane content.In some countries,LPG application is growing fast because of its low refined cost and none excise that governments levy on gasoline and diesel.This paper focused on a combination design of catalyst converter and muffler for material handling vehicles powered by LPG.
