合理使用油料,能够提高自行式工程机械的性能,延长使用寿命,降低成本,节省能源。要做到这点,首先必须熟悉所使用的自行式工程机械的构造性能、工作条件及油料的品种、牌号、性能、用途等,然后进行具体选择。本文简要地介绍一下自行式工程机械的用油。一、对燃料油的选择自行式工程机械主要是以汽油机和柴油机作为动力的,前者以汽油作燃料,后者以柴油为燃料。车用汽油按辛烷值区分为66、70、75、80和85等牌号。66号汽油表示其辛烷值不低于66。辛烷值是表示汽油抗爆性的指标,是汽油的重要质量指标之一。
The rational use of fuel oil can improve the performance of self-propelled construction machinery, prolong its service life, reduce costs and save energy. To do this, you must first be familiar with the structural properties, working conditions, and types, grades, properties, and uses of the self-propelled construction machinery used, and then make specific choices. This article briefly introduces the use of self-propelled construction machinery. First, the choice of fuel oil Self-propelled engineering machinery is mainly powered by gasoline engines and diesel engines, the former to use gasoline as fuel, the latter to diesel fuel. Vehicle gasoline is divided into 66, 70, 75, 80 and 85 grades by octane number. Gasoline No. 66 indicates that its octane rating is not less than 66. The octane number is an index indicating the antiknock property of gasoline and is one of the important quality indicators of gasoline.
