Abstract: A diesel fuel composition comprising from about 70 to about 95 weight percent of dimethyl ether, up to about 20 weight percent of methanol, and from about 0.1 to about 20 weight percent of water is disclosed.

Abstract: The invention relates to high energy, oxygenated fuel compositions suitable for use in compression ignition internal combustion engines which fuel compositions contain a synergistic combination of dimethyl ether, methanol, and water, the combination providing a single liquid phase with good ignition characteristics. More particularly fuels comprising from about 72 to about 95 weight percent of dimethyl ether, from about 0.1 to about 20 weight percent of methanol, and from about 0.1 to about 20 weight percent of water are disclosed.

Abstract: A method is described for operating a spark ignition internal combustion engine utilizing an improved composition containing dimethyl ether and propane as fuel. An engine incorporating the invention produces a lesser amount of certain atmospheric pollutants, such as carbon monoxide and unburned hydrocarbons, as compared to the amount of pollutants produced when the engine is operated at identical conditions with propane as fuel. Also described is an improved fuel composition which exhibits a lower vapor pressure than, for example, propane and, therefore, is relatively easier to liquefy and transport.

Abstract: An inductor housing having a platform for supporting an inductor and a standoff unit for supporting the platform away from a conductor board such that various electrical components can be installed on the conductor board between the inductor platform and the conductor board surface. The inductor housing also has a hole disposed therethrough such that the inductor housing may serve as an insulating standoff support member for connecting a conductor board to a chassis.

Abstract: A rocker arm assembly for use in the valve train of an internal combustion engine of the type having a fixed rocker shaft for supporting at least one rocker arm and having an axial passage adapted to be in continuous communication with the pressurized lubricant supply of the engine and with at least one radial riser passage extending from the axial passage; the rocker arm assembly including a rocker arm having a hydraulic lash adjuster operatively positioned in a socket provided in an arm thereof and, a hybrid bearing operatively positioned in the rocker arm so as to encircle the rocker shaft over the oil riser passage.
