摘要:
An apparatus to coat cylinder bores with precise thickness and adhesion having a nozzle for effecting a hollow conical spray pattern of an emulsion about an axis, a highly pressurized supply of emulsion to the nozzle, the emulsion containing solid lubricant in fluid suspension and means for controllably moving the nozzle within the cylinder bore to deposit a coating of the emulsion in the thickness range of 8-13 microns. A method for coating cylinder bores includes preparing the cylinder bore surface to expose fresh metal free of contamination, generating a hollow conical spray consisting of fine mist droplets of a solid lubricant emulsion (the conical spray having an effective base with a diameter greater than the diameter of the cylinder bore), and moving the apex of the conical spray along the axis of the bore at a uniform speed to deposit a coating of the emulsion on the interior of such cylinder bore in a thickness no greater than 20 microns.

A reciprocating internal combustion engine includes a siamesed piston bore having a configuration formed by the intersection of two circular cylindrical elements and a matching piston having a similar siamesed configuration. This cylinder configuration allows a four cylinder engine to be about 25% shorter with the same displacement as an engine having circular cylinders and the same stroke.

摘要:
A low friction valve train actuating at least one valve in an internal combustion engine includes a cam shaft having at least one cam, a tappet contacting the cam and valve, the cam and valve having outer surfaces with an open porosity, a solid film lubricant impregnated and anchored in the open porosity, the solid film lubricant is stable to temperatures at about 700.degree. F. to retain a low coefficient of friction in an oil starved environment.
摘要:
The invention discloses a method of reducing the concentration of NO.sub.x in the exhaust streams of internal combustion ignitions wherein a selected producing agent is introduced into the combustion chamber of such an engine via the fuel and/or air feed stream introduced into the combustion chamber. Also disclosed is an apparatus for reducing the concentration of NO.sub.x in the exhaust streams of internal combustion engines having a piston-cylinder assembly having an air fuel mixture contained therein, a means for storing a selective reducing agent selected from the group consisting of ammonia, hydrazine and cyanuric acid and a means for introducing the reducing agent into the lean air/fuel mixture before combustion occurs such that upon combustion of the air/fuel mixture, the reducing agent decomposes to react with one or more products of combustion to produce an engine exhaust stream having a reduced concentration of NO.sub.x.
