R660系列柴油机维修保养手册
Maintenace Manual For R660 Series Diesel Engine
第六章 柴油机所用的燃料油、润滑油、冷却水和辅助材料
Fuel Oil, Lubricating Oil, Cooling Water And Auxiliary Materials
1．燃料油
Fuel Oil
夏季：0 号轻柴油 GB252；冬季：-10 号轻柴油 GB252
In summer time: GB 252 Grade No.0 light diesel fuel; in winter time: GB 252 Grade No.-10 light diesel
fuel.
当冬季温度在 -20℃～ -10℃之间用 -20 号柴油；低于 -30℃用 -35 号柴油。燃油规格选择
不当或太脏均可能引起柴油机的故障和损坏，因此选择规格适当的燃油并确保其质量和清洁度是
很重要的。
Use Grade No.-20 diesel fuel if temperature is in the range from -20℃ to -10℃, and Grade No.-35
diesel fuel if temperature is lower than -30℃. Using contaminated fuel or fuel of improper grade may
cause diesel engine failure or damage. Always use high-quality and clean fuel.
2．润滑油
Lubricating Oil
R6160 系列柴油机推荐选用 15W/40 L-ECD 柴油机油 GB11122-1997
It is recommended to use GB 11122-1997 diesel engine oil 15W/40 L-ECD for 170Z-series diesel
engines.
全国夏季、长江以南地区全年也可选用 40 L-ECD 柴油机油 GB11122-1997
40 L-ECD diesel engine oil GB11122-1997 may be selected and used in summer in whole China and for
a whole year in the region south of Yangzi river.
机油在使用中不可避免地要受到从活塞环的缝隙中泄漏下来的高温燃气和从摩擦表面脱落的
金属磨屑的污染，而且在高温下机油会氧化变质。受这些因素的影响，油底壳和机油滤清器中会出
现大量的沉积物和泡沫等，因此必须定期更换机油。更换机油的时间取决于柴油机的使用情况，一
般看机油的情况而定，大约为每 500 小时左右更换一次。换油同时要进行清洁工作，同时检查机油
滤清器，如发现机油滤芯有脏污须清洗滤芯。
Engine oil will inevitably be contaminated during the operation by high temperature combustion gas
leaked from gap of piston ring and abrasive metal dust coming off from friction surface. Further more,
engine oil would become deteriorated as the result of oxidation at high temperature. Therefore, it is
necessary to replace engine oil at regular intervals to remove deposit and foam from oil sump and oil
