  • Publication number: 20110290207
    Abstract: Methods and system for enhancing the fuel economy of a diesel engine is disclosed. The system is useable in a four stroke diesel engine to allow a first injection step to be performed whereby fuel is injected into the cylinders of a diesel engine to initiate combustion of the fuel within the cylinder. A second injection step then occurs, whereby an additive is injected into the cylinder, during the cycle but at a time different than the first injection step wherein the additive reaches the cylinder wall. The additive, which reaches the cylinder wall, provides friction modification and fuel economy benefits for a diesel engine.
