type of lubricant
| maximum torque
| fuel consumption rate (g/kw-hr) | CO emissions(ppm) | Smoke emissions(%) |
commercial oil
| 69.9 | 267 | 865.5 | 21.07 |
NEOMOND-CA | 76 | 241.4 | 818.3 | 15.2 |
⇒ About 9% increase in torque
⇒ Reduced fuel consumption by about 10% (Improved fuel economy)
⇒ Reduced CO and Smoke emissions

type of lubricant
| scuffing (kg) | coefficient of friction
| wear(mm^3) |
commercial oil
| 200 | 0.12 | 0.56 |
NEOMOND-CA | does not occur
| 0.106 | 0.41 |
⇒ Suppression of Scuffing
⇒ Coefficient of friction and wear reduction effect due to nanodiamond particles,
12% reduction in friction coefficient & 27% reduction in wear compared to commercial days
※ Scuffing(Scuffing-adhesive wear, scoring)
As one of the gear damage phenomena, friction and heat remove metal particles from the surface during engine operation.
Occurs due to direct metal contact when proper oil film formation on the friction sliding surface is not achieved.
