为了在通风不良的地方选用叉车,有时制造厂提供以液化石油气(LPG)为燃料的叉车代替以汽油或柴油为燃料的,认为它所产生的废气不那么讨厌。但是最近进行的关于内燃机驱动叉车的有害气体污染研究结果表明,液化石油气(LPG)的废气并不如我们以往认为的那么干净—特别是关于一氧化碳的污染—,而采用催化转换器来消除一氧化碳并不是在任何情况下都是有效的。 To use forklifts in poorly ventilated areas, manufacturers sometimes supply LPG-fueled forklifts instead of gasoline or diesel fuel, considering the exhaust gas it produces less annoying. However, a recent study of harmful gas pollution from internal combustion engine-driven forklift trucks showed that exhaust gas from liquefied petroleum gas (LPG) was not as clean as we thought before - especially with regard to carbon monoxide pollution - and that catalytic converters were used to eliminate carbon monoxide and Not valid under all circumstances.
