Abstract: A control device for a spark-ignition engine, in which a mixture in a combustion chamber is fired by compression ignition in a part-load range under warm-running conditions, includes an EGR controller incorporating a valve operation controller for controlling internal EGR of hot burned gas and a cold EGR controller for controlling external EGR of cold burned gas. The EGR controller performs EGR control operation to leave the hot EGR gas in the combustion chamber in a lower-load, lower-speed region within a compression ignition combustion range and to introduce the cold EGR gas into the combustion chamber in a higher-load, higher-speed region within the compression ignition combustion range. The control device further includes a firing assist unit for inducing the compression ignition at least when ignitability of the mixture decreases due to introduction of the cold EGR gas in the compression ignition combustion range.

Abstract: To provide an internal combustion engine that can generate a strong swirl by increasing the amount of intake air for generating the swirl in a simple structure. In the internal combustion engine provided with a cylinder head formed with an air intake port having first and second ports, when a second intake valve for opening and closing the second port is brought into a halted state by a valve halting mechanism, a swirl is generated by intake air flowing through the first port in a combustion chamber. At a first inlet slot, the line of intersection between a first plane, which is a plan including the first inlet slot and a first orthogonal plane inclines upwardly as it approaches from the position near the outer periphery of the combustion chamber towards a second reference plane, and the first port includes a port section having a passage shape which extends substantially along a perpendicular line orthogonal to a first plane from the first inlet slot towards the upstream by a predetermined length of the passage in a plan view.

Abstract: A lash adjuster is provided which can keep a constant valve lifting amount. An adjust screw is brought into threaded engagement in a threaded hole formed in the bottom surface of an end plate of a lifter body. The adjust screw is biased in the axial direction by an elastic member. The threads of female threads of the threaded hole and the male threads on the adjust screw are serrated. The surface roughness of the pressure flanks of the serrated threads is set to 0.4 or over to prevent the adjust screw from retracting while turning when push-in loads are applied to the adjust screw from the valve stem, thereby stabilizing the valve lifting amount. Also, a slide member is mounted between the adjust screw and the valve stem and a retaining device is provided to prevent the slide member from turning relative to the nut member while supporting it so as to be movable in the axial direction.

Abstract: To provide a high performance four-stroke internal combustion engine wherein an increase in a side of a cylinder head is prevented and a valve resting mechanism is provided for a valve lifter. In a four-stroke internal combustion engine with a valve resting mechanism includes a valve lifter having a valve resting mechanism interposed between a valve motion cam and a stem of a poppet valve and a valve lifter spring is provided for biasing the valve lifter in a direction in which the valve lifter is normally held in contact with the valve motion cam. A slide pin holder is pressed against the valve lifter by a spring force of the valve lifter spring that is provided on the valve lifter while a shim portion having a predetermined thickness for controlling a relative positional relationship with the valve lifter is formed integrally with a valve lifter top wall. One of a plurality of predetermined valve lifters most suitable for the relative positional relationship between the slide pin holder and the valve lifter is selectively mounted to effect a tappet gap adjustment.

Abstract: A tappet is used in a valve-operating mechanism of an internal combustion engine. The tappet has a top wall and the upper surface of the top wall is engaged with a cam. The lower surface is engaged on a poppet valve which moves up and down. A downward projection which has a recess for storing lubricating oil is formed in the middle of the lower surface of the top wall of the tappet, thereby lubricating interfaces with the cam or valve to improve frictional or wear resistance.
