Abstract: Self-adaptive hydraulic variable valve timing system for an internal combustion diesel engine, comprising an electronic control unit, an oil pump, a pressure regulating reversing valve, an oil return tube, an oil line, an oil supply main tube, an oil supply branch tube, and a self-adaptive pushrod length changing assembly. When the engine's oil exceeds 70° C., and engine's rotational speed is greater than or equal to 1300 r/m, and engine's load is greater than or equal to 50%, the control unit is configured to send instructions to the pressure regulating reversing valve to switch oil flow direction towards the oil line which leads to the self-adaptive pushrod length changing assembly and thereby put the engine in an operating mode.

Abstract: The machine combination of an internal combustion engine and the generator of a hybrid drive has two cylinder-piston units, which are arranged parallel to each other in a common housing and each piston of which has a drive connection to an individual crankshaft via connecting rods associated with the pistons. The crankshafts have a counter-rotational connection to each other by gears. This coupling of the two crankshafts by gears allows the internal combustion engine to be combined with a generator in a particularly compact design, in that the shaft of the generator bears a gear, which is arranged in the same plane as the gears of the crankshafts.

Abstract: A computer-implemented method can include receiving a contact point path between a rocker arm pad and a valve tip. The method can include adjusting the contact point path to obtain a modified contact point path that satisfies a design objective of decreased valve tip wear or decreased valve tick. The method can include determining and outputting a custom contour for the rocker arm pad and the camshaft lobe based on the modified contact point path. The custom contoured camshaft lobe can companion with the custom contoured rocker arm pad to produce the modified contact point path for the specified design objective.

Abstract: A flexible coupling linkage (14) anchors a housing (16) that at least partially encloses a rotor (18) of an actuator (22) against rotation, while allowing free movement of the housing (16) in two other planes relative to the rotor (18) to match an angular rotational plane orientation of the rotor (18) to prevent binding between the housing (16) and the rotor (18) due to misalignment. The flexible coupling linkage (14) can be selected from a group of pivot joints (24a, 24b) including at least one of a pivot pin joint (30, 34), a ball-and-socket joint (32), and any combination thereof. The pivot joint (24) defines a restrained point (26a, 26b) associated with the housing (16) radially spaced from an axis of rotation of the rotor (18) preventing rotation of the housing (16) about the axis of rotation of the rotor (18), while allowing angular displacement of the housing (16) about the restrained point (26a, 26b) permitting the housing (16) to match an angle of the rotor (18) to prevent binding between the housing (16) and the rotor (18).
