摘要: A cooling system for an internal combustion engine according to the principles of the present disclosure includes an engine block, a compression device, a cooling circuit, a first pump, and a fuel delivery device. The engine block at least partially defines a combustion chamber and a cooling passage. The cooling passage extends through the engine block. The compression device is received in the engine block to partially define the combustion chamber. The compression device is movable within and relative to the engine block. The cooling circuit is in fluid communication with the cooling passage. The first pump is in fluid communication with the cooling circuit and is configured to circulate a fuel through the cooling circuit and the cooling passage. The fuel delivery device is in fluid communication with the cooling circuit and is configured to deliver the fuel to the combustion chamber.

摘要: In a two-cycle, opposed-piston internal combustion engine, opposed pistons disposed in a cylinder are coupled to a pair of side-mounted crankshafts by connecting rods that are subject to substantially tensile forces acting between the pistons and the crankshafts. This geometry reduces or eliminates side forces between the pistons and the bore of the cylinder. The cylinder and the pistons are independently cooled to reduce cylindrical deformation caused by thermal expansion during engine operation.

摘要: A fuel-injected piston combustion engine with centrally rotating cylinder block and cylinder arranged centrally therein, the rotating cylinder block being surrounded by a stationary housing which seals it off by sealing rings, the housing being provided with two scavenging ports between angles of rotation 180.degree. and 270.degree. calculated in direction of rotation from injection nozzles, an outlet port discharging expanded gases, while an inlet port is connected with a scavenging blower. On both sides in the stationary housing there is mounted eccentrically to the axis of the housing a linear uncranked drive shaft having a rigidly attached connecting arm which at an opposite end, in a piston, is pivotally mounted movable back and forth in the cylinder, arranged in a centrally rotating cylinder block mounted free of forces, in the vicinity of a piston end wall in a connecting rod bearing.

摘要: An internal combustion engine including a cylinder with bore and a piston disposed to reciprocate in the bore is operated by moving the piston in the bore between top and bottom dead center positions and applying lubricant to a portion of the piston that protrudes from the bore. Lubricant is wiped from the piston as the piston travels into the bore toward its top dead center position.

摘要: In an opposed piston engine, a pair of pistons are disposed in opposition in the bore of a cylinder. The cylinder includes first liquid coolant grooves having a first cooling capacity to cool a portion of the cylinder extending from a central portion toward an exhaust port, and second liquid coolant grooves having a second cooling capacity, less than the first cooling capacity, to cool a portion of the cylinder extending from the central portion toward an inlet port. Each piston includes a cylindrical skirt with a crown and an open end opposite the crown, a piston rod with a bore, a first end attached to a back surface of the crown, and a second end extending through the open end of the skirt, a radial array of liquid coolant flow passages in communication with the bore and disposed between the first end and the back surface of the crown, and a single wristpin retained on the second end section of the piston rod and positioned externally to the piston.
