    摘要： An air-fuel mixture intake system of an internal combustion engine includes a helical passage and a straight passage for conducting the air-fuel mixture to an intake port of the engine, the straight passage being selectively closed by a straight passage switchover control valve. A control device for operating the straight passage switchover control valve comprises a valve drive system including a diaphragm adapted to be actuated by intake vacuum of the engine, a vacuum switching valve for selectively either connecting the diaphragm to the intake manifold or releasing the diaphragm to the atmosphere, and a one way valve provided between the vacuum switching valve and the intake manifold so as to hold vacuum on one side thereof toward the diaphragm. Also included is a control system which switches the vacuum switch valve so as to release the diaphragm to the atmosphere when throttle opening increases beyond a certain determinate value thereby to open the straight passage, and which switches the vacuum switching valve so as to connect the diaphragm to the intake manifold when the level of intake vacuum present in the intake manifold rises above a certain determinate level thereby to close the straight passage.

    摘要： An engine comprising an intake port which has a separating wall projecting downwardly from the upper wall of the intake port. The separating wall defines a helical portion, an inlet passage portion tangentially connected to the helical portion, and a bypass passage interconnecting the inlet passage portion and the helical portion. The separating wall has an upstream end portion centrally located between the opposed side walls of the intake port. A rotary valve is arranged in the bypass passage and is actuated by a vacuum-operated diaphragm apparatus. The rotary valve is opened when the amount of air fed into the cylinder of the engine is increased beyond a predetermined value.

    摘要： An engine comprising an intake port which has a separating wall projecting downwardly from the upper wall of the intake port. The separating wall defines a helical portion, an inlet passage portion tangentially connected to the helical portion, and a bypass passage interconnecting the inlet passage portion and the helical portion. The separating wall extends to near the side wall of the helical portion and defines a narrow passage portion therebetween. The width of the upper wall of the inlet passage portion is gradually reduced towards the narrow passage portion. A rotary valve is arranged in the bypass passage and is actuated by a vacuum-operated diaphragm apparatus. The rotary valve is opened when the amount of air fed into the cylinder of the engine is increased beyond a predetermined value.

    摘要： A helically-shaped intake port comprising a helical portion formed around an intake valve, and a substantially straight inlet passage portion tangentially connected to the helical portion. A bypass passage is branched off from the inlet passage portion and connected to the helical portion. A slide valve is arranged in the bypass passage and controlled by an electronic control unit so that the opening area of the slide valve is proportional to the amount of air fed into the cylinder of the engine.

    摘要： A helical type intake port for an internal combustion engine. The system has a first sub-intake passageway and a second sub-intake passageway. The first sub-intake passageway is connected to a helical end of the intake passageway for generating a flow of air for suppression of the swirl effect in the helical end. The second sub-intake passageway is connected to a portion of the helical port located upstream of the helical end portion, for increasing the speed of flow of air directed to the helical end portion.

    摘要： A fuel injection type internal combustion engine comprising a cylinder head having a flat inner wall, and a piston having a flat top face. The flat inner wall and the flat top face form a squish area therebetween. A recess having a lung shaped cross-section is formed in the cylinder head. A shallow groove is formed on the flat inner wall of the cylinder head so as to extend from the intake valve to the recess. The exhaust valve is arranged on the bottom of the recess. A depression connected to the recess is formed on the shallow groove. The spark plug is arranged in the depression. The cylinder head has a portion located between the recess and the intake passage. A fuel injector is arranged in the intake passage. The nozzle of the fuel injector is directed to an inner wall portion of the intake passage, which is located near the recess.
