一、山区及丘陵地区用的节油装置在山区及丘陵地区行驶汽车,经常遇到下坡,往往用挂档滑行。此时,如终止怠速供油,不仅节约汽油,而且保证行车安全,减少机件磨损。现用化油器原设计没有考虑适应这种运行工况时的节油问题,而汽车在这工况运行占有一定比例,怠速节油器及空气节油器就是在下坡挂档滑行时终止怠速供油的节油装置。 First, mountain and hilly areas with fuel-efficient devices In the mountains and hilly areas driving cars, often encounter downhill, often with the gear shift. At this point, such as termination of idle fuel supply, not only save gasoline, but also to ensure traffic safety and reduce wear and tear parts. Existing carburetor original design did not consider to adapt to such operating conditions when the fuel economy, while the car running in this condition occupy a certain percentage, idle fuel economy and air fuel economy is to stop idling downhill gear idle Fuel-saving equipment.
