Adjust the energy structure to solve the problem of tight oil supply and high prices. At present, the price of liquefied gas and natural gas is much lower than that of gasoline, and when the “West-East Gas Pipeline” project is completed, cities along the route will have sufficient natural gas resources. Reduce the impact of cars on urban air pollution. Under the same technical conditions and working conditions, the emission of gas vehicles is much better than that of gasoline vehicles. Therefore, urban development and promotion of gas vehicles can reduce the pollution of the city’s atmosphere by vehicles. The air purification project initiated by 13 ministries and commissions in April 1999? “Clean cars in action” activities accelerated the development of urban gas vehicles.
At present, the number of CNG and LPG gas vehicles in all parts of the country has been rising sharply, and this boom is still heating up. However, in the process of promoting gas vehicles in various places in the past two years, various problems have appeared. Not only did they fail to achieve the desired energy saving and pollution reduction goals, but also caused new energy waste and air pollution. In view of the problems that have emerged in the past two years, this article discusses several issues that should be paid attention to in the development of gas vehicles in cities. The technology of gas vehicles is not yet mature. Among the gas vehicles promoted in China in the past two years, a more serious problem is that each pilot city spends most of its power on the transformation of vehicles (accounting for nearly 80%), while ignoring the development and development of gas vehicles. Production (only 20%). Although the modified car is simple and easy to use, it can be used immediately, but the disadvantages far outweigh the advantages. Whether it is economical, environmentally friendly, or the performance of the vehicle itself, the situation is not optimistic.
