Device for adjusting the intake, exhaust and fuel injection timing of diesel engine

摘要

The present invention relates to a device for adjusting the intake, exhaust and fuel injection timing of a diesel engine. More particularly, the exhaust gas state and the fuel consumption rate of the engine are optimized to the optimum state over the full range of engine operation. In order to maintain the engine's intake and exhaust valves, the opening and closing timings and the fuel injection timings can be automatically changed depending on the operating load during engine operation, and the timing can be changed by simple operation from the outside. Eccentric support shaft 50 for control of intake and exhaust timing, timing control shaft 70, eccentric support shaft 60 for fuel injection timing, and timing control shaft to control the intake, exhaust timing and fuel injection timing independently of each other. 80, respectively, and the timing control shafts 70 and 80 are rotated by the governor connecting lever 92, the rack 77, the pinion 78, and the flat wheels 72 and 82, respectively. Ah D) also move in the axial direction by the screw mechanisms 73 and 83 with the external adjustment wheels 74 and 84, and by the worms 71, 81 and the worm gears 53, 63; By rotating the eccentric support shafts 50 and 60, respectively, the eccentric support shaft, the intake / exhaust valve, and the fuel injection timing can be automatically changed according to the load. (85) or the remote control pneumatic cylinder (76, 86) or the like can not be changed.
