燃气汽车已有60多年的发展历史,经历了从简单的混合器式两用燃料汽车到集闭环控制多点缸内喷射、超稀薄分层燃烧、废气再循环以及三效催化转化等高新技术于一体的单一燃料超低排放绿色汽车的发展过程,技术成熟。目前世界范围内燃气汽车保有量500多万辆。我国石油资源短缺,天然气资源丰富,近年来出于调节能源利用结构和降低城市大气 Gas cars have more than 60 years of development history, from a simple hybrid dual-fuel vehicles to set closed-loop control of multi-point in-cylinder injection, ultra-thin stratified combustion, exhaust gas recirculation and three-way catalytic conversion of high-tech One of the single-fuel ultra-low-emission green car development process, the technology is mature. At present, the number of gas vehicles in the world is over 5 million. China’s oil shortage, rich natural gas resources in recent years out of the adjustment of energy use structure and lower the urban atmosphere
