美国约翰斯·霍普金斯大学和气体研究所的专家正在联合研制新一代的以天然气为燃料的轿车——NGV。它的行驶距离、各种性能均可与目前与汽油为燃料的轿车相匹敌,甚至还要好。更为推崇的是其废气排放量将完全符合加利福尼亚州严格的废气排放标准。这种新一代NGV每加一次天然气就可以跑583km,相比之下目前的NGVS只能跑232～278km,一下子把行车距离提高了2倍左右;而且能使目前使用的NGV与以汽油为动力轿车间的成本差价从3000～5000美元一下子降低50％。由于具有如此多的优点,它足以击败正在行驶的3万辆NGVS中的大多数。
Experts from Johns Hopkins University and the Institute of Gas Research are jointly developing a new generation of natural gas-fueled sedan, NGV. Its range and performance are comparable to and even better than the current gasoline powered cars. More respected is that its emissions will be in full compliance with California’s strict emission standards. This new generation of NGV can run 583km with each additional gas, compared with the current NGVS running only 232 ~ 278km, driving the distance up to 2 times at a time. It also enables NGV currently used and gasoline The difference between the cost of power cars from 3,000 to 5,000 US dollars suddenly reduced by 50%. With so many advantages, it is enough to beat the majority of the 30,000 NGVS that are driving.
