贵州山区公路条件很差,78％是等外公路,居全国之首。所以公路运输安全与汽车节油问题,至今一直是我省运输管理工作中的薄弱环节。为了促进这项工作的技术进步,我省曾研制和试推广过多种汽车节油技术,但大都因结构复杂、成本高或技术性能不可靠等弊端,而难以投放市场。 Guizhou mountain road conditions are poor, 78% are off-highway, ranking first in the country. Therefore, road transport safety and auto fuel economy, has been the province’s transport management weaknesses. In order to promote the technical progress of this work, our province has developed and tried to promote a variety of automotive fuel-saving technologies, but most of them are difficult to put on the market due to their complicated structure, high cost or unreliable technical performance.
