| Summary: | Due to tightening CO2 emission regulations and increasing fuel prices, fuel economy has become one of the greatest issues facing society today. Although molybdenum dithiocarbamate (MoDTC) is a well-known friction modifier for gasoline engines, it has rarely been applied to a diesel application because of the negative effect soot has on the friction-reducing properties of MoDTC. This study examines which soot properties may influence the friction-reducing attributes of oil containing MoDTC. Fuel consumption tests were also conducted using heavy-duty diesel trucks that met the emission standards of the new long-term Japanese regulations. As a result, a fuel economy improvement of around 2% was observed. |
