USE OF DISPERSANT VISCOSITY INDEX IMPROVER IN EXHAUST GAS RECIRCULATION ENGINE |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To obtain a lubricant reducing oil thickening and sludge formation, and to provide an engine using the lubricant. <P>SOLUTION: An olefin copolymer dispersant viscosity index improver is used in a cooled exhaust gas recirculation (EGR) engine so as to reduce or eliminate oil thickening and sludge formation. Thereby, rigorous oil viscosity and emission standards are exactly satisfied. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
