目前佳木斯联合收割机厂产的JL-1075联合收割机,苏联的叶尼塞-1200H联合收割机和T-150K型、(?)型拖拉机,它们的发动机都采用直喷式柴油机。这种直喷式柴油机的气缸工作温度和气缸压力都比较高,所以对发动机润滑油的技术性能指标有较高要求。如果仍采用涡流式及间喷式柴油机用的CA级润滑油,就不能满足需要。因为CA级的HCA-8、HCA-11柴机油,其抗高温及耐高压性能差,使用后很快就会变质,造成发动机润滑不良,加剧各运转部件 At present, the JL-1075 combine harvester manufactured by Jiamusi Combine Harvester Plant, the Yenisei -1200H Combine Harvester and the T-150K Type Tractor (?) In the Soviet Union, all of which use direct injection diesel engines. This direct injection diesel engine cylinder temperature and cylinder pressure are relatively high, so the technical indicators of the engine lubricating oil have higher requirements. If you still use vortex and inter-injection diesel engine with CA-class lubricants, you can not meet the need. Because CA-level HCA-8, HCA-11 diesel engine oil, its high temperature and high pressure performance, will soon deteriorate after use, resulting in poor lubrication of the engine, exacerbating the operation of components
