Abstract: Systems and methods of actuating two engine valves associated with a common engine cylinder using one or more lost motion systems and one or more control valves are disclosed. The control valves are capable of selectively trapping hydraulic fluid in the lost motion systems for auxiliary engine valve actuations and selectively releasing the hydraulic fluid to default to cam controlled valve seating of the engine valves. The systems may provide a combination of main exhaust, compression release, exhaust gas recirculation and early exhaust valve opening in preferred embodiments.

Abstract: An arm coupling mechanism for selectively switching a double valve variable control and single valve variable control. The single valve variable control is achieved in a condition in which a large lift arm and a second rocking cam arm are coupled together with a pin. The second rocking cam arm for moving a second valve includes a pin hole, in which the pin is inserted, formed therein. The position of the pin hole is set so that a pin switching operation can be executed when control is provided to achieve an operating angle, at which the single valve variable control is to be started for reduced NOx. A second driving cam is adapted to have a cam height greater than a cam height of a first driving cam.

Abstract: A control system for an internal combustion engine, which is capable of positively preventing a misfire or knocking during a compression ignition combustion mode by switching from the compression ignition combustion mode to a spark ignition combustion mode in appropriate timing. The engine is operated while switching between the compression ignition and spark ignition combustion modes. The control system (ECU) sets a target operating gas temperature to which the temperature of operating gases in a combustion chamber is to be controlled in the compression ignition combustion mode, sets a target internal EGR amount to which the internal EGR amount is to be controlled, such that the temperature of operating gases in the combustion chamber becomes equal to the target operating gas temperature, and switches the combustion mode to the spark ignition combustion mode depending on the target internal EGR amount.

Abstract: An apparatus for achieving internal EGR in a four-stroke internal combustion engine which, for each cylinder, has at least one inlet valve and at least one exhaust valve for controlling the connection between combustion chambers in the cylinder and an inlet system and exhaust system respectively. A rotary camshaft with a cam curve is designed to interact with a follower member and has a first lobe portion for generating the normal exhaust valve lift of the engine. The camshaft is provided with a second lobe portion, which has a height measurement over and above its basic curve which falls short of the measurement for normal exhaust valve clearance when driving at low load and accompanying low heat development in the engine. As a result of thermal expansion in the valve mechanism, the height measurement exceeds the measurement for normal exhaust valve clearance when driving at high load and accompanying high heat development in the engine. The second lobe portion is situated within a crankshaft angular range of about 360-480 degrees.

Abstract: The invention relates to a switchable cam follower of a valve train of an internal combustion engine, comprising an outer follower and an inner follower interposed between the lateral walls thereof. A roller extends between arms of the inner follower, float-mounted on a pin, as the counter face for an eccentric disk. The followers are disposed on one end on a common axis. On the distal end, they have elongate seats that, at the base of the cam, are mutually aligned. A coupling element is located in the seat of the outer follower and can be displaced step by step into the seat (here follower surface) of the inner follower. The pin on the inner follower slightly projects over the arms of the inner follower with one projection each. When coupled, upper sides of the projections rest against lower sides of stop surfaces that are mounted on the inner surfaces of the lateral walls of the outer follower.

Abstract: The present application provides a sensor adjusting method and a sensor adjusting system for a variable valve mechanism. An actuator is controlled based on an adjustment request signal from an external device in such a manner that a mechanical load of a variable valve mechanism moves to a position where the movement is limited by a stopper. When it is judged that the mechanical load has moved to the position where the movement is limited by the stopper, the mounting position and the electrical characteristics of the sensor for detecting the mechanical load are adjusted so that the output of the sensor assumes a reference value.

Abstract: An electromechanical VVA system for controlling the poppet valves in the cylinder head of an internal combustion engine. The system varies valve lift, duration, and phasing in a dependent manner for one or more banks of engine valves. A rocker subassembly for each valve is pivotably disposed in roller bearings on a rocker pivot shaft between the camshaft and a roller follower. A control shaft supports the rocker pivot shaft for controlling a plurality of rocker subassemblies mounted in roller bearings for a plurality of engine cylinders. The control shaft rotates about its axis to displace the rocker pivot shaft and change the angular relationship of the rocker subassembly to the camshaft, thus changing the valve opening, closing, lift and duration. An actuator attached to the control shaft includes a worm gear drive for positively rotating the control shaft.
