Abstract: A valve operating system for a multicylinder engine opens and closes a pair of valves provided on each of cylinders by means of a pair of rocker arms operated by a cam provided on a camshaft supported on a cam holder. When viewed in a direction of a cylinder axis, the pair of rocker aims of at least one of the cylinders are inclined in opposite directions to each other with respect to a direction orthogonal to a camshaft axis. Therefore, thrust loads acting on the camshaft from the pair of rocker al is are counteracted individually for each of the cylinders, thereby enabling the thrust load to be reduced and axial movement of the camshaft to be prevented.

Abstract: A helical torsion valve spring assembly includes one or more helical torsion springs mounted within a frame and are held in a statically loaded state so that installation of a valve spring retainer can be easily performed. The entire helical torsion valve spring assembly is installed as a single part onto a cylinder head of an engine valvetrain. The helical torsion springs are mounted around a shaft to accurately locate the helical torsion springs so that the forces acting on the retainer and valve are precisely controlled. The assembly minimizes the size of the retainer, and applies only one bending mode to the helical torsion springs, which provides maximum utilization of the spring material and minimizes coil vibration. The assembly allows spring coils to be strategically packaged in the engine valvetrain to create space in critical areas.

Abstract: An internal combustion engine is operable in an efficiency mode providing a first power output range between zero and a transition power output and in a power mode providing a second power output range between the transition power output and a maximum power output. The efficiency mode can include a first ignition timing and a first air/fuel ratio of the mixture to avoid premature auto-ignition, and the power mode can include a second ignition timing and a second air/fuel ratio of the mixture to avoid premature auto-ignition of the mixture. To further enable knock free operation of such an engine, turbulence can be imparted to the mixture to promote a faster burn duration and high temperatures that may lead to premature auto-ignition of the mixture can be avoided.

Abstract: Valve assembly and method in which a valve member is connected to an elongated lever arm for controlling communication between two chambers in an engine. The valve assembly is disposed at least partially within one of the chambers, and the valve member is moved between open and closed by an actuator connected to the lever arm. In some disclosed embodiments, a pilot valve is opened to equalize pressure on both sides of the valve member prior to moving the valve member toward the open position. In others, where a piston in an expansion cylinder is driven by hot, expanding gases from a separate combustion chamber or heat exchanger, the exhaust valve is closed before the piston has completed its exhaust stroke, and pressure is allowed to build up in the expansion cylinder to a level corresponding to the pressure in the combustion chamber before the valve member is moved toward the open position.

Abstract: A driver that reciprocates has its reciprocation divided into a non-actuating portion and an actuating portion. The driver in one embodiment positions a carrier that has two pins, each pin being slidably mounted in its slot on a housing. One of the pins is an output pin that may be linked to operatively position a valve of an internal combustion engine. The two slots are configured such that each pin, during its motion range, does effect a capture of the other pin such that the captured pin is generally stationary. When the output pin is captured, the driver reciprocation causes the non-output pin to perform a lost-motion traverse of its slot. When the non-output pin is captured, the driver reciprocation actuates the output pin. A linked pair of such embodiments driven by a single driver can thus alternately actuate two valves.

Abstract: The rocker arm assembly has an anti-inversion part that prevents a support pin from inverting, ensuring proper orientation of the support pin, on which a rocker arm is rotatably mounted, is maintained. The anti-inversion part can be a washer, a plate, a plug, or a sleeve. The washer, which has a flat face and a curved face, is intended for use with a cylindrical support pin which matches the curved face of the washer. The plate can include various combinations of tabs, flanges, and/or protrusions that extend in different directions. The plug can resemble any desirable shape, and is removed prior to final assembly. The sleeve can be hollow and is removable.
