  • Patent number: 11008908
    Abstract: An oil passageway structure for internal combustion engines includes a cylinder head having an inter-bearing wall fluid communication oil passage for providing fluid communication between a plurality of bearing walls to allow oil to flow therebetween. The cylinder head further includes a bearing wall oil passage branched from the inter-bearing wall fluid communication oil passage to supply oil to a bearing surfaces of at least one of the bearing walls. The inter-bearing wall fluid communication oil passage is defined in one of facing side walls. The bearing wall oil passageway is defined in at least one of the bearing walls. The oil passageway structure is thus made up of a reduced number of parts, can be assembled with a reduced number of man-hours, can lead to productivity growth, and is inexpensive to manufacture.

  • Patent number: 10858969
    Abstract: An engine variable valve train is provided with a cylindrical cam carrier fitted on a camshaft in a manner axially slidable to and co-rotatable with the camshaft. The cam carrier has therearound mutually adjoining low-speed and high-speed cam lobes selectively acting on the engine valve and being different in cam profile. The cam carrier has therearound lead grooves to be engaged with or disengaged from changeover pins for axial shift of the cam carrier. The lead grooves include a speed-increasing lead groove for changeover from the low-speed to the high-speed cam lobe and a speed-decreasing lead grooves for changeover from the high-speed to the low-speed cam lobe. The speed-increasing and speed-decreasing lead grooves are different in groove contour. This enables the cam carrier to axially shift smoothly and to improve the durability of the lead grooves.

  • Patent number: 10677112
    Abstract: An internal combustion engine is provided with a variable valve operating apparatus, for use on a saddle-type vehicle. When a switching drive shaft is longitudinally moved under hydraulic pressure switched by a solenoid valve, a cam mechanism advances and retracts a switching pin. When the switching pin is advanced to engage in a lead groove in a cam carrier, the cam carrier is axially moved while rotating, to switch cam lobes to act on an engine valve. A solenoid valve is disposed on a left or right end in the leftward and rightward directions across the vehicle width, of a front or rear surface of a cylinder head. The solenoid valve is placed in an appropriate location in the cylinder head out of interference with other parts of the engine, thereby making the vehicle small in size.

  • Patent number: 10677114
    Abstract: A variable valve operating device for an internal combustion engine includes a cam carrier supported on a camshaft and shifting switching pins that are advanced into and retracted out of shift lead grooves defined in the cam carrier. The shift lead grooves include shift groove side walls having shift groove side wall surfaces from shift starting inflection regions of the cam carrier to shift ending inflection regions thereof. The shift groove side walls include particular shift groove side walls extending from axial positions of the shift starting inflection regions toward shift intermediate regions and also extending from circumferential positions of the shift intermediate regions disposed between the shift starting inflection regions and the shift ending inflection regions toward the shift starting inflection regions.

  • Patent number: 10598055
    Abstract: An engine variable valve operating apparatus includes a cam switching mechanism having a switching drive shaft. When the switching drive shaft is longitudinally moved, a cam mechanism advances and retracts a switching pin. When the switching pin is advanced to engage in a lead groove formed around a cam carrier and the cam carrier is axially moved while rotating, cam lobes around the cam carrier are switched to act on an engine valve. An actuator for the switching drive shaft includes an actuator drive body which is linearly reciprocally movable and is coupled to a longitudinal end of the switching drive shaft to axially move the same. The above arrangement enables the cam switching mechanism and the actuator mechanism to be simple and compact in structure for preventing the engine from becoming large in size.

  • Patent number: 10473004
    Abstract: A variable valve train of an internal combustion engine has cylindrical cam carriers axially slidably and co-rotatably fitted on camshafts, respectively. The cam carriers have, respectively, first cam lobes and second cam lobes different in cam profile and axially adjacent to each other. Cam changeover mechanisms operate to axially shift the cam carriers to change over the first cam lobes and the second cam lobes to operate engine valves. An axial recess is formed in an axial end surface of an enlarged-diameter portion of the camshaft for axial insertion of an end of the cam carrier. The engine can thus be reduced in axial size, and a required axial shifting space for the cam carrier is secured.

  • Patent number: 10378396
    Abstract: A variable valve-operating device for an internal combustion engine has a cam carrier with cam lobes formed therearound to act on an engine valve and with a speed increasing side lead groove and a speed decreasing side lead groove formed therearound to be engaged with a speed increasing side switching pin and a speed decreasing side switching pin, respectively, to axially shift the cam carrier, to selectively make one of the cam lobes to be operative. A speed increasing side entry lead groove portion of the speed increasing side lead groove is formed in a position axially overlapping a low speed steady position lead groove portion of the speed decreasing side lead groove. A speed decreasing side entry lead groove portion of the speed decreasing side entry lead groove is formed in a position axially overlapping a high speed steady position lead groove portion of the speed increasing side lead groove. The variable valve-operating device can thus be miniaturized by reducing the axial width of the cam carrier.
