在农业生产中,常使用小型、轻便的小马力汽油机,由于它起动容易,不少功率较大的以柴油机为主机的拖拉机上采用小汽油机作起动用的副机。这样即使在严寒的气温下,柴油机也能比较方便地起动。由于它比较轻便,在一些农业机械上直接用它作动力,如带动插秧机、拔秧机、弥雾喷粉机、水田中耕除草机、割草机和收割机等,进行移动作业。也有用它进行抽水、脱粒、铡草、发电等固定作业。 In agricultural production, it is common to use a small, lightweight, small-horsepower petrol engine. Because of its ease of starting, many of the more powerful diesel-based tractors use a small gasoline engine as a starting accessory. In this way, the diesel engine can start more easily even in a cold temperature. Because it is relatively light, in some agricultural machinery directly use it as a driving force, such as driving the rice transplanter, rice transplanter, misting dust mower, paddy field cultivator, lawn mowers and harvesters, etc., for mobile operations. It is also useful for pumping, threshing, hay, power generation and other fixed operations.
