Abstract: A system according to the principles of the present disclosure includes a switching period module and at least one of a valve lift control module and a start-stop control module. The switching period module determines a switching period that elapses as a valve lift actuator of an engine switches between a first valve lift position and a second valve lift position that is different than the first lift position. The switching period begins when a measured position of the valve lift actuator corresponds to the first lift position and the switching period ends when the measured position of the valve lift actuator corresponds to the second lift position. The valve lift control module controls the valve lift actuator based on the switching period. The start-stop control module determines whether to automatically stop the engine based on the switching period.

Abstract: An internal combustion engine is provided with a DOHC-type valve train in a cylinder head. The valve train includes an intake side camshaft with an intake side driven gear, and an exhaust side camshaft with an exhaust side driven gear. The cylinder head supports therein a spindle with an idle gear with an idle chain sprocket fixed thereto. The idle gear is in meshing engagement with both the intake and exhaust side driven gears. Rotary power of a crankshaft is transmitted via a cam chain to the idle gear to rotate both the intake and exhaust side camshafts. These camshafts are supported by bearings of a bearing wall and a camshaft holder. These bearings and camshaft holder are located, for compact arrangement, at a position axially coinciding or overlapping with the idle chain sprocket.

Abstract: A method for controlling an electric variable cam timing (VCT) actuator is disclosed. The method includes during engine shutdown, adjusting camshaft position with an electric VCT actuator to a target starting location, applying a first current to the electric VCT actuator to maintain the target starting location, and during engine startup before camshaft position feedback becomes available, applying a second current to the electric VCT actuator to maintain the target starting location.

Abstract: A control system for an engine includes a first lift control module and a second lift control module. The first lift control module increases lift of M valves of the engine to a predetermined valve lift during a period before disabling or re-enabling N valves of the engine. The second lift control module decreases the lift of the M valves to a desired valve lift during a period after enabling or re-enabling the N valves of the engine, wherein N and M are integers greater than or equal to one.

Abstract: An engine assembly may include an engine structure, a piston, a first valve and a first valve actuation assembly. The engine structure may define a combustion chamber and a first port in communication with the combustion chamber. The piston may be located within the combustion chamber and be reciprocally displaceable between a top dead center position and bottom dead center position. The first valve may selectively open and close the first port. The first valve actuation assembly may be engaged with the first valve and be operable in first and second modes. The first valve actuation assembly may be operated in the first mode when fuel is provided to the combustion chamber and operated in the second mode when fuel is cutoff from the combustion chamber. The first mode and second modes may provide different opening durations of the first valve in order to reduce vacuum in the combustion chamber.

Abstract: A decompressor disposed to start an engine by a recoil starter and at this time compression pressure within a cylinder is adapted to escape therefrom, in which a decompression valve of the decompressor is disposed vertically with respect to a crank shaft or within a crank casing, so that a decompression valve does not laterally project from the cylinder and does not interfere with a cowling, whereby a compact engine is laid out, and also an interlocking mechanism of the decompression valve with the recoil starter becomes simple. Furthermore, a cam at the recoil reel is made variable correspondingly to the kind of engine so that the decompression timing during the starting is made variable so as to obtain the most suitable starting mechanism.

Abstract: An engine having an engine block defining at least two cylinders having respective cylinder heads. Pistons are reciprocal within respective ones of the cylinders. The cylinders have respective fuel inlet ports and exhaust ports and two of said cylinders have an idle relief port disposed between their respective exhaust port and head ends. The idle relief ports of the cylinders are interconnected by a passageway for providing communication between the idle relief ports of said at least two cylinders. This has been found to provide reduced pull start resistance, reduced engine vibration during idle, and significantly reduced horsepower loss over a wide operating range which horsepower loss is normally associated with idle prior art relief structures which vent directly from idle relief ports to atmosphere.
