Abstract: Methods and apparatus for providing bleeder-type and compression-release engine braking in an internal combustion engine are disclosed. For bleeder-type engine braking, the exhaust valve is maintained at a small and relatively constant lift throughout all or much of the engine cycle. The engine braking may be combined with exhaust gas recirculation, variable exhaust brake, and/or operation of a variable geometry turbocharger.

Abstract: A generally conventional lash adjuster is modified by incorporating a coaxially oriented hydraulic control piston assembly within the guide body. The control piston normally fixes latch means, such a plurality of hard spheres, in multiple detents loaded in compression with the other components, to provide a rigid stop, but when the control piston is hydraulically pressurized, the detents are overcome and the piston assembly provides a resilient or soft stop that accommodates extended displacement (retraction) of the lash adjuster within the guide. The hydraulic actuation is preferably implemented with a three-way solenoid valve or the like, for controlling high-pressure oil to a gallery and associated inlet ports for the control piston assembly. In the typical implementation of the invention, the piston need have only two operational positions-denergized to establish the detent or hard stop condition, or fully energized to establish the valve deactivation position. With all of preferably four detents in quadrant symmetry and associated components in compression, side loading is avoided. Moreover, with the present invention, backlash is also avoided.

Abstract: A system for actuating a valve element in an engine valve assembly of an internal combustion engine is provided. The system has a first piston that includes a first rod and is disposed in a first chamber. The system also includes a second piston that has a second rod with an end being separated from the engine valve assembly by a predetermined distance. The second piston is disposed in a second chamber that is in fluid connection with the first chamber such that movement of the first piston causes a corresponding movement of the second piston. A cam having a cam lobe is operatively engaged with the first rod such that rotation of the cam and cam lobe moves the first piston to thereby move the second piston. The cam lobe has a shape adapted to cause the second rod to move through the predetermined distance and to engage the engine valve assembly to move the valve element at a predetermined point in the operating cycle of the internal combustion engine.

Abstract: A twin cylinder engine, includes a pair of cylinder members mounted to mounting surfaces of a crankcase, and cylinder heads mounted to the cylinder members. The cylinder members are modular components, which may be pre-assembled with components of the valve train as packaged units before the cylinder members are attached to the crankcase. Each cylinder member rotatably supports a cam gear which extends into the crankcase for driving engagement with the crankshaft. The cylinder members may be configured for either side valve-type (nullL-headnull), or overhead valve-type (nullOHVnull) engines, and the cylinder members may also be used in single cylinder engines.

Abstract: An intake and exhaust system for an internal combustion engine having a unitary engine block the system comprising a power cylinder, an intake lifter cylinder and an exhaust lifter cylinder that are formed integral with the engine block. This engine block has an intake port, and an exhaust port for allowing exhaust to flow there through. Inside the piston or power cylinder is a power piston which is driven by a crank shaft connected by connecting rod which extends through the power cylinder. This crank shaft is driven by a movement of the power piston which is caused by combustion of gasses inside the engine block. There is also a cam shaft which disposed within the engine block. This cam shaft is found on a top section of the engine block. Coupled to the cam shaft is a timing chain which is also coupled to said crank shaft. Thus, as the crank shaft rotates, it drives the timing chain which in turn rotates said cam shaft. To control the flow of exhaust gasses and the intake of air mixture, there is an intake lifter disposed in the engine block adjacent to the engine block intake port. There is also an exhaust lifter disposed in the cylinder adjacent to the exhaust port. To drive the intake lifter and the exhaust lifter, there is at least one oblong cam disc coupled to the cam shaft wherein this at least one oblong cam disc is for driving the intake lifter and said exhaust lifter intermittently so that exhaust can flow through the engine block from the intake port and out of the exhaust port.
