    Abstract: A cylinder liner is disclosed. The cylinder liner may include a hollow generally cylindrical body extending from a top end to a bottom end along a longitudinal axis, and an annular flange extending radially outwardly from the top end of the body. The cylinder liner may also include an annular recess adjacent the flange at a side closest to the bottom end of the body. The recess may have first and second axial ends, a substantially straight portion extending between the first and second axial ends, and at least one fillet formed at an intersection between the straight portion and at least one of the first and second axial ends. A roll-burnishing operation may be performed on the straight portion and the at least one fillet in a direction along the longitudinal axis.

    Abstract: Objects of a cylinder cover for diesel engine is to prevent the interference of mists between a plurality of fuel valves, thereby enhancing the spray efficiency, and to prevent troubles of burning of nozzle caused by the collision of mist sprayed from the adjacent fuel valve and increase in thermal stress caused by local overheat of combustion chamber surface due to the collision of mist. To achieve these objects, fuel valves are mounted in a side wall of the cylinder cover so that the centerline thereof is substantially at right angles to the cylinder centerline. Further, the injection angle of the fuel valve is set so as to be an acute angle not larger than 90.degree. to prevent local collision of mist with the combustion chamber wall surfaces, and the volume of the volume portion at the tip of the fuel valve is decreased to the minimum.

    Abstract: This invention relates to a reciprocating internal combustion engine having a cylinder crankcase with a cylinder head with is designed to reduce the manufacturing and spare parts cost. A single design unified cylinder head is employed for liquid cooling and air cooling, the cylinder head having both cooling spaces for the liquid coolant and cooling fins for the cooling air. Coolant passageways in the cylinder head are connected to coolant spaces in the cylinder block portion of the cylinder crankcase by way of openings in the upper end of the cylinder block and openings in the cylinder head gasket which permit flow of coolant to the annuli in the cylinder head. In addition to the annuli, the coolant passageways in the cylinder head include a longitudinally extending header, horizontally extending web ducts extending radially inward from the annuli and vertically extending connecting conduits inclined relative to the cylinder axes interconnecting the web ducts and the header. Each connecting conduit extends through a pillar extending between the cover plate portion and the base portion of the cylinder head. The pillars are in the wind shadow of, and in a substantially parallel relationship to, injection nozzles installed in the cylinder head.

    Abstract: An engine block is formed by a single piece lower crankcase and a single piece upper crankcase having abutting surfaces sealed with a gasket. The abutting surfaces have semicircular notches aligned with one another to form a circular opening for a crankshaft. The upper crankcase includes central section from which extends a barrel unit that contains the entire cylinder bore for a piston. An integral housing for the cylinder valves and rocker arms is formed on the barrel unit and an integral intake manifold extends from the housing. Forming the engine block from two primary components reduces the number of joints that require machining and gaskets.
