    Abstract: A method of attaching an internal combustion engine piston oiler includes the step of removing a crank shaft from an internal combustion engine to expose a plurality of block main bearing surfaces, selecting a drill guide shaped to fit one of the engine block main bearing surfaces, which drill guide has a predetermined drill guide bore therethrough, and positioning the selected drill guide on the engine block main bearing surface. The method includes positioning a drill bit through the bore in the selected drill guide and drilling a predetermined bore through the engine block webbing from one main bearing surface into the rear of the engine cylinder and then tapping the bore drilled into the engine block and installing an oil metering jet into the drilled and tap bore. The method also includes drilling an aperture into the oil groove in the crank shaft main bearing generally aligned with the engine main bearing surface drilled opening and then replacing the crank shaft in the engine block with the engine oil jet installed to enhance the lubrication of the engine piston dome and wrist pin. The process is repeated for each of the engine cylinders.

    Abstract: An engine of a motorcycle is provided with a lubricating apparatus and a crank case within which is mounted a crank shaft having one end extending outwardly from a side wall of the crank case, and a cam sprocket drive gear is mounted upon the crank shaft. A cam chain chamber within which a chain is disposed in a loop is formed upon one side of a cylinder block including a cylinder and a piston and a cylinder head disposed above the cam sprocket drive gear. An oil passage hole is formed within a mating face of the crank case to be mated with the side cover, and an oil passage tube is inserted into the oil passage hole. The oil passage tube has a front end provided with at least one oil jetting hole and extends through an inner space defined by means of the looped cam chain and extends further so as to penetrate the side wall of the crank case so that the oil jetting hole is directed toward a lower surface of the piston when the latter is disposed at a lower dead position from the lower side of the piston so as to jet oil guided through an oil passage formed within mating faces defined between the crank case and the side cover towards the lower surface of the piston. The rear portion of the oil passage tube is provided with an engaging piece so as to firmly secure the tube to the crank case.

    Abstract: The present invention is an improved lubrication system for a connecting rod, wrist pin, and piston of a compressor. An oil pump pumps lubricating oil upwardly within an axial bore of the crankshaft, which includes a radial passageway in alignment with the connecting rod. The connecting rod includes ports which direct pulses of oil onto the inner surfaces of the piston. The ports are separated by barrier segments to allow local oil pressure to build between the sequential alignments of the passageway and a port. Thus, pulses of oil are accurately sprayed onto the piston inner surfaces without substantially diminishing the lubrication of the journal bearings.

    Abstract: A two cycle engine has oil distribution means through the cylinder wall to feed internal oil passages in the associated piston that distribute oil directly to the skirt and cylinder walls, preferably between ports, and/or to the wrist pin and connecting rod bearing to thereby limit oil carryover into the engine charging and scavenging air.

    Abstract: There is disclosed an internal combustion engine with reduced emission of sound, heat and harmful substances. The characteristics of an air-cooled engine are optimized as a result of withdrawal of heat by oil in uniform distribution along the entire peripheries of the cylinders. For this purpose, there was developed a lower piston portion which effects uniform distribution of cooling oil along the periphery. The external cooling is improved in that the entire periphery of each free-standing cylinder is provided with a recessed ring-shaped oil guide and in that the free-standing cylinders are located in a common chamber which is cooled by oil sprays. More pronounced uniformity of such cooling action along the entire periphery of each cylinder allows for the selection of a higher temperature level of the cylinders which is important for combustion of vegetable oils in lieu of mineral oil products. At the same time, the above construction strives to accomplish the object of improving the power density and running characteristics of a diesel engine.

    Abstract: A piston assembly for an internal combustion engine is made up from a piston main body and a lubricant reservoir defining member. The piston main body has a cup-shaped structure including a crown portion and a hollow cylindrical wall portion joining thereto, two piston pin bosses being formed at opposite sides of the wall portion. The lubricant reservoir defining member is made from a shelf plate main body portion which provides a central lubricant reservoir and two openings on its opposite sides, and two major legs extending from the shelf plate main body portion and each formed with a hole surrounded by an annular portion. Each of the annular portions is engaged with an inner end portion of a corresponding one of the bosses and surrounds the piston pin hole thereof. Thus the lubricant reservoir defining member is securely mounted within the cup shaped piston main body by a reliable and simple construction, with the shelf plate portion generally parallel to and opposing the piston crown and thereby providing a central lubricant reservoir for aiding with the flow of cooling lubricant flowing in and out through the two openings to flow along the underneath of the piston crown.

    Abstract: A rotary piston internal combustion engine of the trochoidal type with a housing. The engine includes at least one peripheral wall portion and at least two parallel side portions and has induction and exhaust ports. Each peripheral wall portion and two associated side portions define a cavity in which a multi-apex piston is rotatably mounted to define variable volume working chambers. The piston is provided with seal elements which are in sliding engagement with the inner surfaces of the housing. The seal elements are provided with a passage for lubricating the inner surfaces of the housing with the passage opening into the cavity in the neighborhood of each induction port in the region of that working chamber which is undergoing the induction phase. The passage is in communication with the atmosphere and has a lubricant feed pipe opening into it. A restriction is provided in the passage between its point of entry into the cavity and the point of entry of the lubricant feed pipe. The restriction has a cross sectional area for a flow of a maximum of about 30% of the idling air consumption of the engine. The point of entry of the passage into the cavity is arranged so that it is cut off by the piston at the latest at the instant of closing of the induction port or ports by the working chamber that is undergoing the induction phase.
