摘要： It comprises one or more cylinders with pistons therein and mutually opposed power cams connected to respective first and second rotary shafts. The reciprocating pistons act on the power cams to impart a rotating motion to the rotary shafts. An attachment device is provided for connecting the rotary shafts to each other. The attachment device includes a shifting device for changing the relative angular position of the first and second rotary shafts. The result is engine distribution and compression ratio are changed dynamically.

摘要： An opposed piston engine includes approximately spherical combustion chamber formed by the two opposed pistons in a single cylinder and an intake manifold including gas hooks. The combustion chamber has a small cone shaped extension on each side leading to each of two opposed injectors located in the cylinder wall where the two pistons meet at the top of their stroke. The combustion chamber configuration reduces the surface area of the chamber and increases the burn length by a significant amount compared to known designs. The gas hooks in the intake manifold restrict the flow of exhaust gases into the intake manifold long enough for the pressure in the cylinder to blow down and the exhaust gasses to attain high velocity passing out through the exhaust manifold, allowing the intake ports to be uncovered before the exhaust ports.

摘要： An eight cylinder engine includes cylinders that are fired at intervals corresponding to a crank angle of 90 degrees. The firing is conducted in four cylinders of each of first and second banks at uneven intervals. In a pair of cylinders of each of the banks in which the firing is consecutively conducted at an interval corresponding to a crank angle of 90 degrees, a central angle of an exhaust cam provided for one cylinder in which the firing is conducted later is larger than that of an exhaust cam provided for the other cylinder. In a pair of cylinders of each of the banks in which the firing is consecutively conducted at an interval corresponding to a crank angle of 270 degrees, a central angle of an exhaust cam provided for one cylinder in which the firing is conducted later is larger than that of an exhaust cam provided for the other cylinder.

摘要： An opposed-piston engine system equipped for full hybrid compressed-air/combustion includes capacity for storing air compressed by the engine during a combustion mode of operation. The hybrid opposed-piston engine system includes a control mechanization for operating the opposed-piston engine in a combustion mode by provision of fuel, in a compressed-air mode by provision of stored compressed air, and in a combustion mode supplemented by provision of stored compressed air. A method of operating a hybrid vehicle equipped with an opposed-piston engine includes storing air compressed by the engine during a combustion mode of operation and operating in the vehicle a compressed-air mode by provision of stored compressed air.

摘要： With reference to FIG. 2, the invention relates to an opposed stepped piston two-stroke engine comprising at least a first and a second cylinder, wherein the air piston is a stepped piston providing a first air transfer piston that expands and compresses a first air transfer volume to deliver air from the first air transfer volume to an air transfer system, and the exhaust piston is a stepped piston providing a second air transfer piston that expands and compresses a second air transfer volume to deliver air from the second air transfer volume to the air transfer system, each of the first and second air transfer volumes having an air inlet for receiving air; and wherein the air transfer system provides fluid connection between the respective first air transfer volume of each cylinder and the air port of another respective cylinder, via respective first air transfer conduits, and fluid connection between the respective second air transfer volume of each cylinder and the air port of the other respective cylinder, via respective second air transfer conduits, wherein the drive system is configured, for each cylinder, to have a predetermined phase angle such that one of the exhaust piston and air piston is driven before the other piston, causing delivery of air from its respective air transfer volume to the air transfer system before delivery of air occurs from the other of the air transfer volumes.

摘要： An internal combustion engine is provided. Facing pistons eliminate a cylinder head, thereby reducing heat losses through a cylinder head. Facing pistons also halve the stroke that would be required for one piston to provide the same compression ratio, and the engine can thus be run at higher revolutions per minute and produce more power. An internal sleeve valve is provided for space and other considerations. A combustion chamber size-varying mechanism allows for adjustment of the minimum size of an internal volume to increase efficiency at partial-power operation. Variable intake valve operation is used to control engine power.

摘要： In an air handling system of a uniflow-scavenged, two-stroke cycle opposed-piston engine, one or more engine operating state parameters are sensed, numerical values of air handling parameters based on trapped conditions in a cylinder of the engine at the last port closing of an engine operating cycle are determined in response to the sensed parameters, the numerical values are evaluated, and one or more of the numerical values is adjusted in response to the evaluation. The adjusted numerical values are used to control charge air flow and EGR flow in the air handling system.
