旧柴油机改造技术是通过基础修理和优化调整,在不改变原机基本结构的基础上,换装少量节能配件,达到节油的目的。改造的机型以195柴油机为主,其他机型有495、695、190、4115和4125等。随着农业机械保有量日益增加,农机用油日趋紧张,旧柴油机改造技术推广是提高机车技术状态,缓解农机用油供需矛盾的一项重 Old diesel engine transformation technology is through the basis of repair and optimization of the adjustment, without changing the basic structure of the original machine, based on the replacement of a small amount of energy-saving accessories, to achieve the purpose of fuel-efficient. The modified model is mainly 195 diesel engine, the other models are 495,695,190,4115 and 4125 and so on. With the increasing possession of agricultural machinery, agricultural machinery oil increasingly tight, the old diesel engine to promote technological upgrading is to improve the technical status of locomotive to ease the contradiction between supply and demand of agricultural machinery, a heavy
