天然气汽车概况 天然气汽车是指以天然气作为燃料的汽车,按天然气的化学成分和形态,可分为压缩天然气(CNG)汽车、液化天然气(LNG)汽车和液化石油气(LPG)汽车3种。目前,我国的天然气汽车大多数为双燃料汽车,驾驶员可通过转换装置选择天然气或燃油。 天然气汽车是一种理想的低污染汽车,与燃油汽车相比,它的尾气排放中HC下降90％、CO下降80%、NO_x下降约40% 。1996年,美国福特汽车公司研制的天然气轿车达到了美国加州超低排放标准。日本丰田汽车公司
Natural Gas Vehicle Overview Natural gas vehicles are natural gas-fueled vehicles that can be classified into CNG, LNG and LPG according to the chemical composition and morphology of the natural gas. At present, most of China’s natural gas vehicles are dual-fuel vehicles, and the driver can select natural gas or fuel through the conversion device. A natural gas vehicle is an ideal low-pollution vehicle with a HC reduction of 90%, a CO reduction of 80% and a NOx reduction of about 40% compared to a fuel-efficient vehicle. In 1996, the natural gas sedan developed by Ford Motor Company reached the ultra-low emission standard of California. Japan Toyota Motor Corporation
