摘要： A cylinder head for an engine is formed with a first straight intake passage which leads to a first intake port, and with a second helical intake passage which leads to a second intake port and is formed with a helical end vortex portion. A common intake passage leads to the upstream ends of the first and second intake passages. A dividing ridge extends from one side of the inner surface of the cylinder head defining the intake passages towards but not reaching an opposite side of that surface, with a gap being left beween the ridge summit portion and that opposite side. The ridge thus divides the second intake passage into a one side portion remote from the first intake passage and terminating in the helical end vortex portion, and another side portion towards that first intake passage which is a straight bypass passage and is communicated at its downstream end to that helical end vortex portion. The upstream end of the ridge is positioned substantially upstream of the point at which the common intake passage becomes bifurcated into the first and second intake passages. A control valve is fitted in the common intake passage between its wall and this upstream ridge end, so as to control the flow resistance of the first straight intake passage and the straight bypass passage. Optionally, the portion of the control valve on the ridge side of the cylinder head inner surface is substantially upstream of the portion thereof on the opposite side thereof.

摘要： A gasoline in a material fuel tank is separated into a high-RON fuel having a higher octane value than the material fuel and a low-RON fuel having a lower octane value than the material fuel, by a separator device equipped with a separation membrane. Using a fuel switching mechanism, one or both of the high-RON fuel and the low-RON fuel are supplied to the engine in accordance with the state of operation of the engine. As the octane value of a fuel can be changed in accordance with the engine operation state, the state of combustion in the engine improves, so that both an increase in engine output and an improvement in an exhaust property can be achieved.

摘要： An internal combustion engine has a cylinder block formed with first and second cylinder bores, and first and second pistons are fitted in the bores and reciprocate in them. A cylinder head is affixed to the cylinder block and defines first and second combustion chambers in cooperation with the first and second pistons and cylinder bores. This cylinder head is formed with a portion which in cooperation with a portion of the first piston defines a squish area of the first combustion chamber, with a cylinder fixing bolt hole boss being located between the first portion and the second portion of the cylinder head, and being disposed towards the side of the cylinder head on the side of the squish area. Further, the cylinder head is formed with a side wall defining one side of a coolant passage which substantially follows through the cylinder head proximate to the squish area so that a first portion of the coolant passage directly cools the squish area. A second portion of the coolant passage passes around the boss at least between it and the side wall of the cylinder head, and directs flow of coolant through it to the first coolant passage portion. Optionally, this second coolant passage portion may also pass around the other side of the boss.

摘要： A variable swirl siamese type intake port structure for an internal combustion engine cylinder head includes a first generally straight intake passage which leads to a first intake port and a second generally helical intake passage which leads to a second intake port which is formed with a helical end vortex portion. A control valve is fitted in the first generally straight intake passage at an upstream portion thereof so as to control its flow resistance. A means is provided to the generally straight intake passage on the side thereof towards the generally helical intake passage, for, when the control valve is in its position to maximize the flow resistance of the generally straight intake passage, diverting a relatively minor proportion of air-fuel mixture sucked into the intake port structure from a point upstream of the control valve to a point near the downstream end of the first generally straight intake passage, thus bypassing the control valve. Further, there is provided a means for biasing flow of air-fuel mixture sucked into the intake port structure towards the diverting means. This diverting means may include an auxiliary passage formed from upstream of the control valve to a portion of the generally straight intake passage near the downstream end thereof, or alternatively a notch portion formed in said control valve, preferably in the edge thereof which is on the side thereof towards said generally helical intake passage.

摘要： A variable swirl siamese type intake port structure for an internal combustion engine cylinder head includes a first generally straight intake passage which leads to a first intake port and a second generally helical intake passage which leads to a second intake port which is formed with a helical end vortex portion. A control valve is fitted in the first generally straight intake passage at an upstream portion thereof so as to control its flow resistance. A substantially straight auxiliary passage, opening from a point upstream of the control valve to a point near the downstream end of the first intake port and bypassing the control valve, points through the first intake port, when open, generally at the ignition point of the engine spark plug. Thereby, when the control valve is closed, even then an air-fuel mixture stream is directed straight at the spark plug, and this prevents local weakening of mixture due to centrifugal effects. Thus good ignition characteristics are obtained, the limit for weakening the air-fuel mixture can be extended, and the engine volumetric efficiency and the maximum attainable engine output power are increased.

摘要： A solenoid valve device includes an engine valve which can move in an axial direction thereof, an armature which moves with the engine valve, an electromagnet which attracts the engine valve so that the engine valve moves in the axial direction, and a zero-lash adjuster mechanism which is interposed between the engine valve and the armature. Thus, the solenoid valve can positively actuate an engine valve between a fully closed position and a fully opened position without formation of a clearance between the engine valve and the armature. A current supplied to the electromagnet may be set in accordance with a value which is related to a relative position of the armature and the electromagnet.
