摘要: A control device for a multicylinder spark-ignition engine includes a flow path switching unit for switching intake and exhaust flow paths between a two-cylinder interconnect configuration and an independent cylinder configuration and an air-fuel ratio control unit. In a low-load, low-speed operating range, the flow path switching unit switches the engine to the two-cylinder interconnect configuration, and the air-fuel ratio control unit produces a lean mixture having an air-fuel ratio larger than the stoichiometric air-fuel ratio by a specific amount in preceding cylinders by injecting fuel thereinto and an air-fuel ratio approximately equal to the stoichiometric air-fuel ratio in following cylinders by supplying fuel together with burned gas of a lean mixture state discharged from the preceding cylinders into the following cylinders to perform combustion in special operation mode. At engine startup, the flow path switching unit switches the engine to the independent cylinder configuration to perform combustion in normal operation mode.

摘要: A valve drive mechanism includes a generally cylindrically shaped tappet assembly (24) comprising a center tappet (41 ) and a side tappet (42). The center tappet (41 ) has a circular-arcuate side walls (41c) formed with vertical side shrouds (41d) at opposite sides of each side wall (41c) which overlap and slide contact with opposite end guide walls (42h) of the side tappet (42), respectively. When the tappet assembly (24) is in an unlocked state so as to transmit rotation of the side cams (25, 27), the vertical side shroud (41d) of the center tappet (41 ) slide on the vertical side walls (42h) of the side tappet 42 so as thereby to guide slide movement of the center tappet (41) relative to the side tappet (42).

摘要: A valve drive mechanism includes a tappet assembly which comprises a center tappet, a pair of side tappets between which the center tappet is interposed so as to move relatively to the side tappets, and a locking/unlocking mechanism operative to mechanically couple the center tappet to both of the side tappets and to uncouple the center tappet from both of the side tappets so as to selectively transmit rotation of a high lift center cam and low lift side cams to twin valves such as twin intake valves and twin exhaust valves per cylinder. Locking/unlocking of the center tappet and each side tappet is performed in a position which is in a vertical plane including a center axis of each side tappet and intersecting perpendicularly to an axial direction of a camshaft and is offset from the center axis of the side tappet.
