2、 but also caused serious pollution. 汽车排放污染对大气污染的分担率达到了30%-60%(而被称为“绿色汽车”的天然气汽车在环保方面具有显著效益，汽车尾气中一氧化碳可减少97%，碳氢化合物减少72%，二氧化硫减少90%，噪音减少40%，致使人体呼吸道疾病及癌症的苯、铅粉尘等减少100%)，已成为城市污染的要紧来源。Automobile polluting emissions account for 30% -60% of air pollution, having become a major source of urban pollution (howeve

3、r, green cars using clean natural gas have significant environmental benefits; carbon monoxide, hydrocarbons and sulfur dioxide in vehicle exhaust are reduced by 97%, 72%, and 90% respectively, in addition to noise reduction of 40%; benzene, lead dust which can lead to human respiratory disease and

4、cancer are reduced by 100%). 天然气汽车进展从上世纪30年代起，已有70连年的历史，专门是近些年来，先进的电子技术和机械制造技术使天然气汽车的平安性和操纵性能取得保证，续驶里程由初始5070千米提高到300-400千米以上；天然气汽车气瓶重量和加气站的体积大为减少；给汽车加注天然气同加注燃油一样方便，快速充气仅需515分钟，因此天然气汽车技术已趋于成熟。Since its development in the 30s of the last century, CNG vehicles have developed for some 70 years. Especia

5、lly in recent years, advanced electronics and mechanics have greatly enhanced the safety and performance of CNG vehicles. Continued driving distance has increased from the initial 50 70 kilometers to over 300-400 km, and cylinder weight and the size of filling stations have seen a significant drop.

6、It is equally convenient to fill gas as oil fuel, and fast filling only takes 5 to 15 minutes; all this shows that CNG vehicle technology has matured. 目前世界上天然气汽车保有量已超过600万辆(其中货运和客运车中以柴油/天然气单燃料车占多数)，要紧散布在富气贫油的意大利、新西兰、阿根廷、印尼等国家和环保法规严格的美国、日本等。Currently, there is a CNG vehicle ownership of over 6 millio

7、n (of which freight and passenger cars are mostly diesel / CNG single-fuel type), distributed predominantly in Italy, New Zealand, Argentina, Indonesia and other countries with rich reserves of gas and scanty oil resources, and in countries with strict environmental regulations like United States an

8、d Japan. 欧美的一些专家以为，从技术成熟度、经济性、易普及程度、资源等方面因素看，柴油/天然气单燃料汽车是最具进展潜力的汽车。Some European and American experts believe that, based on factors of technical maturity, economy, easy penetration and resource availability, diesel / CNG single-fuel vehicles have huge development potential. 从进展的目光看，我国有可能进入天然气开发和应用领

9、先的国家行列，因此，在现时期大力进展柴油/天然气单燃料车是解决油价节节升高，运输本钱不断上涨，加油站布局不合理，石油供需矛盾突出的有效途径和保障车辆正常运营的有效手腕。From a development perspective, China may enter the ranks of the leading countries in exploration and application of natural gas. Therefore, diesel to CNG single-fuel conversion can be used effectively to address iss

10、ues of escalating oil prices and transportation costs, irrational filling station distribution and the obvious contradiction between oil supply and demand, and to ensure the normal running of vehicles.
