A Diesel engine anti-wear lubricant oil additive composition that includes organo-metallic compounds of Cu, Ce, etc. , is used to catalytically burn-off diesel particulate matter (PM) collected by diesel particulate filter (DPF). A fuel borne catalyst (FBC) of Cu,Ce,Fe etc. , required for regenerating the DPF is made by blending a predetermined quantity of used engine oil, removed from the engine crankcase oil system, with fuel in the fuel tank of a diesel engine equipped with DPF and EGR systems. A method of fumigating water and catalytic compounds of Cu, Fe, Ce, etc. , into the air-intake system of a diesel engine in the EGR gases from the DPF or air, to reduce both PM and NOx emissions from a diesel engine, with improved engine lubrication performance, is also disclosed.

A hydrated EGR system, method and apparatus for a vehicle, in which heat from an exhaust pipe is used to heat an aqueous fluid solution in a water tank. A portion of the hot exhaust gas is diverted from the main exhaust flow, and the diverted portion is bubbled through the heated aqueous fluid solution to form a hydrated EGR mixture containing water vapor. The hydrated EGR mixture is then fed back to an intake portion of the engine, is mixed with an incoming fuel/air mixture, and is burned with the fuel air mixture inside the engine. The use of the hydrated EGR mixture, including heated water vapor, as part of the intake charge simultaneously reduces harmful exhaust emissions, improves engine performance, and improves fuel economy of the vehicle.

60274

A diesel engine exhaust filtration system and method which removes both diesel particulate matter (DPM) and unburned hydrocarbons (UHC) from the exhaust gases. Two filters in parallel are used, each alternating operation as the other regenerates. Each filter is preferred to be constructed in a conventional manner and operates at between 100 to 300 degrees Centigrade. A microprocessor controlled valve system regulates which filter is active and which is regenerating and/or inactive. DPM accumulates at the active filter, with UHC condensing on the DPM. When the active filter becomes clogged, the microprocessor switches it to inactive status, and switches the other filter to active status. Low temperature regeneration is initiated by the microprocessor in which DPM and UHC burn slowly across the entire filter. A recirculation conduit provides for the gases produced by the regeneration to be directed to the air intake of the diesel engine.

A combustion box exhaust filtration system and method which removes both particulate matter (PM) and unburned hydrocarbons (UHC) from the exhaust gases. Two filters in parallel are used, each alternating operation as the other regenerates. Each filter is preferred to be constructed in a conventional manner and operates at between 100 to 300 degrees Centigrade. A microprocessor controlled valve system regulates which filter is active and which is regenerating and/or inactive. PM accumulates at the active filter, with UHC condensing on the PM. Accordingly, only PM and UHC free gasses pass out the exhaust. When the active filter becomes clogged, the microprocessor switches it to inactive status, and switches the other filter to active status. Regeneration of the inactive filter is initiated by the microprocessor using a glow plug at a predetermined location in the filter, in which PM and UHC burn slowly across the entire filter. A recirculation conduit provides for the gases produced by the resulting slow regeneration to be directed to the air intake of the combustion box.
