摘要： In a direct fuel-injection engine equipped with a pentroof-shaped piston, cross-sectional shapes containing a piston central axis (Lp) of a cavity recessed in a central part of the piston having a top face with the height varying in the circumferential direction are set so as to be basically identical at each position in the circumferential direction (see broken line). Since the sizes of the cross-sectional shapes of the cavity thereby become different in a region further on the piston central axis (Lp) side than intersection points (e1, d1) in the vicinity of a fuel injection point (Oinj), in order to compensate for this, by correcting in a cross section that is away from the piston pin direction the cross-sectional shape of the broken line into the cross-sectional shape of a solid line so that it enlarges, the size of the cross-sectional shape at each position of the circumferential direction of the cavity is thereby made more uniform, thus making the conditions in which fuel and air are mixed uniform and improving the engine output and reducing harmful exhaust materials.

摘要： A control system for an internal combustion engine having a plurality of cylinders each having at least one intake valve, at least one exhaust valve, and a crankshaft. The control system has an electromagnetic driving section which electromagnetically causes opening and closing of at least one of the at least one intake valve and the at least one exhaust valve. A crank angle sensor generates a crank angle signal whenever the crankshaft rotates through a predetermined angle, and a cylinder position sensor generates a cylinder-discriminating signal indicative of a predetermined crank angle of a particular cylinder of a plurality of the cylinders. A piston position sensor detects an operating state or position of the piston of each of the plurality of the cylinders, based on the generated crank angle signal and the generated cylinder-discriminating signal. A CPU starts opening of the at least one of the at least one intake valve and the at least one exhaust valve, based on the detected operating state of the piston.

摘要： An intake system for an internal combustion engine includes first and second intake valve bores provided to face a combustion chamber and to be independently opened and closed by first and second intake valves, and first and second intake ports which are connected to the corresponding intake valve bores with a partition wall interposed therebetween and which communicate with a common intake passage. In a particular operation range of the engine, an imbalance is produced in the concentration of the air-fuel mixture flowing through the first and second intake valve bores into the combustion chamber on the basis of a difference between the amounts of fresh air flowing into the first and second intake ports. The intake system further includes a communication hole provided in the partition wall for putting the first and second intake ports into communication with each other. This provides for improvements in the lean combustibility and in the nature of the exhaust gas.

摘要： A method of controlling an internal combustion engine having at least one intake valve comprises the steps of (1) detecting a demand of the driver to the engine, (2) detecting operating parameters of the engine including engine rotational speed, and (3) setting the timing of closing the at least one intake valve to timing which makes output of the engine the maximum at the detected engine rotational speed, when it is detected that the driver demands that the maximum output of the engine should be obtained in at least a predetermined operating region of the engine. In another form of the invention, when the knocking of the engine is detected, the timing of closing the at least one intake valve is advanced or retarded by a predetermined amount from timing applied before occurrence of the knocking such that the engine has intake efficiency thereof lowered, at least in a predetermined operating region of the engine determined based on at least the detected demand of the driver to the engine and the detected engine rotational speed, and the advancing or retarding of the timing is continued even after the knocking of the engine ceases to occur.

摘要： A valve operating system for an internal combustion engine, including a cam having an arcuate base circle portion with the center thereof being aligned with the rotational axis of the cam and a raised portion projecting radially outwardly from the base circle portion, a cam-side piston operatively connected to the cam, a valve-side piston operatively connected to an engine valve, a hydraulic pressure chamber between the cam-side piston and the valve-side piston, an oil pressure supply source connected to the chamber through a check valve, a hydraulic pressure releasing valve connected to the chamber, and a solenoid valve or the like for controlling the operation of the releasing valve. This solenoid valve or the like is arranged to open the releasing valve to release the hydraulic pressure in the hydraulic pressure chamber in accordance with the operational position of the engine valve. This ensures complete seating of the engine valve and enables part of the working oil in the chamber to be periodically replaced to prevent excessive rise in oil temperature.

摘要： A direct fuel-injection engine includes a piston, a cavity recessed in a central part of a top face of the piston, and a fuel injector. At a main injection collision point of a fuel-injection axis when main injection is performed while the piston is near top dead center, a main injection collision angle formed between its tangent and the fuel-injection axis is set at an obtuse angle. Fuel colliding with the main injection collision point is deflected towards a cavity open end side. At a secondary injection collision point of the fuel-injection axis when performing secondary injection with the piston is further from top dead center, a secondary injection collision angle formed between its tangent and the fuel-injection axis is set at one of a right angle and an acute angle. Fuel colliding with the secondary injection collision point is deflected primarily in the circumferential direction of the cavity.

摘要： In a direct fuel injection diesel engine equipped with a pentroof-shaped piston, a collision angle (α) at which fuel injected in a direction in which the height of the top face of a piston (13) is high collides with a cavity (25) is set larger than a collision angle (β) at which fuel injected in a direction in which the height of the top face of the piston (13) is low collides with the cavity (25). By so doing, in a direction in which the height of the top face is high fuel that has collided with the cavity (25) easily rebounds upward, thus achieving effective combustion by mixing with a large amount of air present in the vicinity of the opening of the cavity (25) where the height is high, and in a direction in which the height of the top face is low it is difficult for fuel that has collided with the cavity (25) to rebound upward, thus achieving effective combustion by suppressing the flowing out of fuel or flame from the opening of the cavity (25) where the height is low, thereby appropriately mixing fuel and air in all directions in the circumferential direction of the cavity and making it possible to improve the engine output and reduce harmful exhaust substances.
