    摘要: A combustion mode transition control for controlling a transition between a homogeneous-charge compression-ignition (HCCI) combustion mode and a spark-ignition (SI) combustion mode includes slowly transitioning intake and exhaust camshafts from initial phase settings corresponding to one of the HCCI and SI combustion modes to target phase settings corresponding to the other of the HCCI and SI combustion modes. An ignition spark timing and an injected fuel mass are coordinated with the transitioning of the intake and exhaust camshaft phase settings to substantially maintain engine load continuity during the transitioning of the intake and exhaust camshaft phase settings.

    摘要: A suction system of an internal combustion engine, comprising a reed valve in the suction pipe in the vicinity of the suction port for opening and closing the passage of the suction pipe thereby preventing the backward flow of gases, said reed valve having a valve seat member with a valve opening thereon, a support pin pivotally and eccentrically supporting the valve seat member, and a reed fixed on the valve seat member so as to open and close the valve opening of the valve seat member, and means for opening the passage of the suction pipe by rotating the valve seat member only when the engine speed is high.

    摘要: A method for operating a reciprocating internal combustion engine in an engine braking mode includes, in a working cycle of the engine braking mode, a first outlet valve of a first cylinder is closed for a first time, then opened for a first time, and subsequently closed for a second time, and then opened for a second time, in order to thereby discharge gas that has been compressed in the first cylinder from the first cylinder by a cylinder piston. The outlet valve is held open after the first opening and prior to the second closing long enough for the cylinder to be filled with gas that flows out of a second cylinder via at least one outlet channel, where when the engine braking mode is activated, at least one camshaft for activating at least one gas exchange valve of the reciprocating internal combustion engine is adjusted.

    摘要: An internal combustion engine (10) with variable valve timing has one or more valve shafts (38, 44) connected to stepper motors (54) for angularly positioning the one or more valve shafts (38, 44) relative to an engine block (12). Flow passages (50, 52) are formed into the one or more valve shafts (38, 44) for passing intake air and exhaust gases into and from the engine (10). Sensors (58, 60 and 62) are located adjacent a crankshaft (28) and the one or more valve shafts (38, 44) for determining crankshaft positions and valve shaft positions relative to the engine block (12). An engine control unit (56) receives crank shaft and valve shaft position signals and emits control signals to the stepper motors (54) to selectively operate the engine in two stroke, four stroke, six stroke, eight stroke, and ten stroke modes. Electrically controlled clutches (74 and 76) are mounted to respective ones of the crankshaft (28) and the valve shafts (38, 44), and connected by a timing chain (72) for actuating to provide backup valve shaft.

    摘要: An engine generator has an opening and closing mechanism including: a control shaft provided to a valve shaft of a choke valve to be rotatable relative thereto within a predetermined angular range; an urging member urging the valve shaft relative to the control shaft in a direction in which an opening degree of the choke valve decreases; a restriction mechanism that sets a minimum opening degree of the choke valve by restricting a range of rotation of the control shaft; a choke operating portion which, upon operation, drives the restriction mechanism in a direction in which the minimum opening degree of the choke valve decreases; and a negative pressure mechanism driven by a negative pressure generated during an operation of the engine to cause the control shaft to rotate to increase the minimum opening degree of the choke valve within the range of rotation restricted by the restriction mechanism.
