    摘要： A piston engine may include a non-contact bearing between a piston assembly and a cylinder. The piston may be configured to translate in a bore of the cylinder, and a non-contact bearing may be included in a clearance gap between the piston assembly and the bore. A bearing fluid may be supplied to the clearance gap via the piston assembly and/or cylinder to create the non-contact bearing. A bearing element may be used to direct or otherwise manage the flow of bearing fluid in the clearance gap. The bearing element may include one or more holes, porous portions, and/or passages to direct the bearing fluid to the clearance gap.

    摘要： Air air-cooled multi-cylinder internal combustion engine with a cylinder row through which cooling air flows transversely to the cylinders. Two guide ribs are cast-on at the cooling air discharge side of each cylinder at a distance to one another which are constructed as thin-walled profiles and are angularly bent through about 90.degree. in mutually opposite directions.

    摘要： In a motorcycle engine having front and rear engine blocks arranged along the longitudinal line of a vehicle body, the front engine block is equipped with cooling fins for air-cooling and the rear engine block is provided with a water jacket for water-cooling. The engine may be a V-type engine or a horizontal opposed-type engine. The present invention is applicable to a motor scooter having left and right steps for placement of the feet of the driver to place his feet, the steps being installed in the lower portion of the vehicle body between the front and rear wheels of the vehicle.

    摘要： A replaceable monolithic, hollow, generally cylindrical cylinder liner formed of hot pressed silicon nitride adapted for operating at the high engine temperatures caused by fuel combustion and friction within the liner without need for liquid cooling thereof. The liner includes a surface adjacent its outer end for forming a radial press fit with the inside surface of the cylinder cavity and a stop-engaging surface formed on the cylindrical liner surface spaced axially inwardly of the press fit surface or along the innermost face of the liner for engaging an engine block liner stop within the cylinder cavity.

    摘要： A reciprocating piston internal combustion engine, each cylinder of which is provided at the connection point of light metal cylinder head and cylinder sleeve with a sealing element. On that surface which is directed toward the combustion chamber, the sealing element is provided with a heat insulating layer. This heat insulating layer serves for thermal insulation of the sealing surfaces of the light metal cylinder head and the cylinder sleeve in order to reduce thermal stresses and radial relative movements resulting from non-uniform thermal expansion characteristics. The end face inner surface of the cylinder sleeve is preferably also thermally insulated.

    摘要： The invention contemplates an improved ported cylinder construction and method wherein the precision of die-casting is used in the separate construction of a cylinder body and of a cylinder liner wherein ports and grooves are so formed in these parts as to cooperatively define inlet and exhaust passages, upon correctly registered assembly of the ports. In the specific form disclosed, the assembled cylinder provides for side-ported exhaust and an array of inlet-mixture passages for communicating a crankcase-compressed combustible charge to liner-bore regions selected for best scavenging of exhaust products.
