    摘要： An auxiliary air intake passage defining member 41 is connected to an air intake pipe 36 connected to a cylinder head 23. The auxiliary air intake passage defining member 41 defines an auxiliary air intake passage K1. The auxiliary air intake passage K1 is branched from a main air intake passage P1 in the air intake pipe 36 to guide intake air into a space defined adjacent to an injection nozzle of an injector at least during idling. At least a part of the auxiliary air intake passage defining member 41 is located outside a shroud 50. A portion around the injection nozzle is cooled by assist air from the auxiliary air intake passage K1 during idling. A portion around the injection nozzle is cooled by cooling wind generated by a fan 56 during the movement of a vehicle.

    摘要： An engine unit (30) disposed below a storage box is pivotable about a pivot shaft (31) together with a rear wheel with respect to a vehicle body frame. An air intake pipe (36) that defines a part of a main air intake passage (P1) is connected to an engine body (21) of the engine unit (30). An auxiliary air intake passage (K1) branched from the main air intake passage (P1) between a first and second throttle valves (40A,40B) disposed in the air intake pipe (36) is provided. The auxiliary air intake passage (K1) guides intake air into a space adjacent to an injector at least during idling. A pivot shaft (31) is disposed at a lower position than a cylinder axis (L1) of a cylinder block (22) and in a forward direction with respect to a crank case (24).

    摘要： An internal combustion engine comprises a cylinder body having at least one cylinder and a cylinder head provided with a plurality of air intake and exhaust valves. These intake and exhaust valves are actuatable via air intake and exhaust camshafts in cooperation with respective rocker arms mounted at respective exhaust and intake rocker shafts and associated with said cylinder. Further, there is provided a dynamic valve apparatus being capable to variably control the valve opening and closing timing, the valve lift, and the shut down of at least some of said air intake and exhaust valves. The dynamic valve apparatus comprises a moving mechanism for moving respective rocker arms between an operational position in which a cam nose of each of said camshafts is in sliding contact with said rocker arms and a non-operational position in which said rocker arm is offset of said cam nose in axial direction of said exhaust and intake rocker shafts in accordance with detected engine operational conditions.

    摘要： An internal combustion engine (1) comprises a cylinder block defining at least one cylinder, and a cylinder head connected to the cylinder block. The cylinder slidably accommodates a piston defining a combustion chamber with the cylinder and the cylinder head, which supports a spark plug (45) projecting into the combustion chamber. An intake system and an exhaust system are provided, whereby said intake system has an intake passage (12) branching into a plurality of branch passages (21,22,23) leading to intake valve controlled intake ports (28) and an exhaust gas recirculation means (56) for introducing exhaust gas into the intake system. Within said intake system an air/fuel mixture is created predominantly in at least one (22) of the branch passages (21,22,23) oriented towards a spark plug ignition area (46) of the combustion chamber while at least one (21,23) of the further branch passages comprise an exhaust gas introduction opening downstream of an air intake control valve (38).
