1.前言到目前为止,从节能和降低环境污染出发,乳化柴油侄小型内燃机的研究、试验和应用,已在全国广泛的开展了起来。但大、中型内燃机的研究和试验却很少,尤其用于火车机车上,几乎还未着手进行。个别单位曾对机车内燃机,使用乳化油能否达到节油作了单缸 1. Foreword So far, from the energy saving and environmental pollution reduction, the research, test and application of emulsified diesel nephew small internal combustion engine have been widely carried out nationwide. However, large and medium-sized internal combustion engines are rarely studied and tested, especially for locomotives and locomotives and have not yet been started. Individual units of the locomotive internal combustion engine, the use of emulsified oil can achieve fuel-efficient made a single cylinder
