| titleOfInvention | Lubricant oil composition for internal combustion engines |
| abstract | This invention provides a lubricant oil composition for internalncombustion engines which shows a sufficiently low volatility at highntemperature and good low-temperature viscosity characteristics. n The lubricant oil composition for internal combustion enginesncomprises a base oil which simultaneously satisfies the following relationshipsn(a 1 ) and (b 1 ):n (a 1 ): [(A•GCD5-50 + B)Exp ((C•GCD5-50 + D)KV100)]/KV40 > 1, and (b 1 ): E•Exp (F•KV100)/KV40 > 1, nwherein, GCD5-50 is a difference between 5% and 50% distillation points (°C)nby gas chromatographic distillation test, KV40 and KV100 are kinematicnviscosities (mm 2 /s) at 40°C and 100°C, and A to F are constants, A: -3.17 x 10 -3 ,nB: 2.87, C: -3.78 x 10 -4 , D: 4.91 x 10 -1 , E: 9.41, and F: 2.09 x 10 -1 . |
