在拖拉机单缸发动机上安装限油器,可以有效地控制发动机超负荷运行,对降低油耗、减小烟度、延长机车的使用寿命确有好处。但是,几年来限油器的使用和推广工作却不甚乐观,原因何在?最近,我走访了有关科研单位、拖拉机生产厂家及部分机手,得到的答案是值得思索的。近年来,种类繁多的限油器应运而生。其中大部分是由科研院所、大专院校联合有关厂家研制的。作为科研成果,研制单位要求积极推广是不言而喻的。但是,一些拖拉机生产厂及广大机手却另有一些想法。洛阳拖拉机研究所发动机工程部副主任袁聪同志说:几年来,除少数厂认识到单缸柴油机安装限油器确有好处,并在出厂的单缸柴油机上全部装上限油器 Installing a limiter on a single-cylinder tractor engine can effectively control overloading of the engine and is good for reducing fuel consumption, reducing smoke and prolonging the service life of the locomotive. However, the application and promotion of the limiter have not been very optimistic in recent years. What is the reason? Recently, I visited the relevant scientific research institutes, tractor manufacturers and some of the specialists and the answers we got were worth considering. In recent years, a wide range of oil limiter came into being. Most of them are developed by joint research institutes and tertiary institutions. As a result of scientific research, development units require active promotion is self-evident. However, some tractor manufacturers and the vast majority of other hands have some ideas. Comrade Yuan Cong, deputy director of engine engineering department at Luoyang Tractor Institute, said: In recent years, except for a few factories, it has been realized that a single cylinder diesel engine is equipped with a fuel limiter and is fully equipped with a fuel limiter on a single cylinder diesel engine
