柴油机如果出现故障,不论故障大小,都会降低柴油机的效率,增加油耗。因此,认真维护柴油机,有问题应当立刻予以修复,是降低柴油机油耗(燃油油耗和机油消耗)的有效方法之一。要使柴油机节油运行,需做到以下几点。(1)保持柴油机气门间隙的最佳状态是柴油机省油的基本之一。如果柴油机的气门间隙不正确,就会使进气不充分,排气不干净,不可避免地造成柴油机过量空气 Diesel if failure, regardless of the size of the fault, will reduce the efficiency of diesel engines and increase fuel consumption. Therefore, serious maintenance of diesel engines, problems should be immediately repaired, is to reduce diesel fuel consumption (fuel consumption and oil consumption), one of the effective methods. To make diesel fuel-efficient operation, to be done the following points. (1) to maintain the best diesel engine valve clearance is one of the basic fuel-efficient diesel engine. If the diesel engine valve clearance is not correct, it will make inadequate intake, exhaust is not clean, inevitably cause excessive diesel engine air
