Definitions

  • the present invention relates to a decompression device for promoting start of a 4 stroke cycle internal combustion engine using a starter motor.
  • a mechanical decompression device has been known (see Japanese Laid-Open Patent Publication No. Hei 11-107727 , Japanese Laid-Open Patent Publication No. 2000-199412 and Japanese Patent Publication No. 2890218 ).
  • the mechanical decompression device is operated to open an intake valve or an exhaust valve in case that rotational speed of a camshaft is lower than a predetermined value, and set to a non-operative state by centrifugal force of a weight in the decompression device in case that rotational speed of the camshaft exceeds the predetermined value.
  • An electrical decompression device has been also known (see Japanese Laid-Open Patent Publication No. Hei 11-324744 ).
  • the electrical decompression device is operated by excitation of an electromagnetic solenoid to promote rotation of a crankshaft of the engine, and after the crankshaft has reached a rotational speed at which the engine can start rotation by itself not relying on the starter motor, excitation of the electromagnetic solenoid is cancelled to cancel operation of the decompression device.
  • the decompression device since it is required to excite the electromagnetic solenoid only when operation of the decompression device is necessary, the decompression device can be miniaturized. However, an electronic judgment device for discriminating operation and non-operation of the decompression device is necessary, and it is difficult to apply this decompression device to a small-type 4 stroke cycle internal combustion engine having no electronic control apparatus. Further, even in case of an internal combustion engine having an electronic control apparatus, the electronic control apparatus becomes complicated.
  • the present invention relates to an improvement of a decompression device of a 4 stroke cycle internal combustion engine for overcoming the above-mentioned difficulties.
  • the present invention provides a decompression device of a 4 stroke cycle internal combustion engine having intake and exhaust valves opened and closed by respective intake and exhaust cams made integral with a camshaft and a starter motor for starting the engine, comprising: a decompression cam fitted on the camshaft so as to rotate freely; a one-way clutch fitted on the camshaft which is adjacent to the decompression cam and capable of transmitting reverse rotation torque to the decompression cam only when the camshaft rotates in reverse; a torque limiter inserted between the decompression cam and the one-way clutch for canceling transmission of the reverse rotation torque larger than a predetermined torque; a first decompression cam stopper provided on a fixed portion engaging with an engaging section formed on the decompression cam for stopping rotation of the decompression cam in normal rotational direction; and a second decompression cam stopper provided on a fixed portion engaging with
  • the exhaust valve or the intake valve is opened by the decompression cam having a lift larger than the base circle of the exhaust cam or the intake cam, so that occurrence of a large normal rotation resistance torque to the crankshaft in compression stroke is avoided and the crankshaft can rotate with a large rotational acceleration.
  • the torque limiter may be formed so that torque transmitted through the torque limiter is smaller when the camshaft rotates in normal direction and larger when the camshaft rotates in reverse direction.
  • the decompression cam can be rotated in reverse surely overcoming reverse rotation resistance given to the decompression cam by the exhaust valve and decompression preparation state can be set easily.
  • the torque limiter may comprise a touching member disposed on one of adjacent side surfaces of the one-way clutch and the decompression cam, a depression formed on another of the adjacent side surfaces and a spring for forcing the touching member against the depression, and the depression may be shaped so that transmitted torque is smaller when the camshaft rotates in normal direction and larger when the camshaft rotates in reverse direction.
  • the torque limiter may comprise a touching member disposed on one of adjacent circumferential surfaces of the one-way clutch and the decompression cam, a depression formed on another of the adjacent circumferential surfaces and a spring for forcing the touching member against the depression, and the depression may be shaped so that transmitted torque is smaller when the camshaft rotates in normal direction and larger when the camshaft rotates in reverse direction.
  • Figs. 1 and 2 show a single-cylinder OHC 4 stroke cycle internal combustion engine 1 for a motorcycle having a decompression device according to the present invention.
  • the main body of the internal combustion engine 1 comprises a cylinder block 2, a cylinder head 3 provided on an upper end of the cylinder block 2 detachably and a crankcase (not shown) provided at a lower portion of the cylinder block 2.
  • a piston 5 is fitted in a cylinder bore 4 of the cylinder block 2 so as to slide up and down.
  • the piston 5 is connected to a crankshaft (not shown) through a connecting rod so that the crankshaft is driven to rotate when the piston reciprocates up and down.
  • the cylinder head 3 is formed with an intake passage 7 and an exhaust passage 8 communicating with a combustion chamber 8 at an upper position of the cylinder bore 4.
  • An intake valve 9 and an exhaust valve 10 for opening and closing the intake passage 7 and the exhaust passage 8 are arranged in V-shape.
  • the intake valve and the exhaust valve 10 are always forced to close by valve springs 12 inserted between the cylinder head 3 and retainers 11 integrally attached to tops of the intake valve 9 and the exhaust valve 10.
  • On an upper stream side of the intake passage 7 are arranged a throttle valve and a carburetor.
  • a camshaft 13 is pivotally supported by means of a pair of bearings 14.
  • a driven sprocket 16 is integrally attached to an end of the camshaft 13 by bolts 15, and an endless chain 17 is laid over the driven sprocket 16 and a drive sprocket (not shown) fixed to the crankshaft (not shown).
  • the camshaft 13 is driven so as to rotate with a rotational speed equal to half of that of the crankshaft.
  • rocker shafts 18 are supported by the cylinder head 3 in parallel with the camshaft 13.
  • Each of the rocker shafts 18 has an intake rocker arm 19 or an exhaust rocker arm 20 pivoted so as to rock.
  • Each rocker arm 18, 19 has an end with a tappet screw 21 fixed by a lock nut 22 and another bifurcated end.

  • a one-way clutch 29 is positioned outside of the exhaust cam 28 and fitted on the camshaft 13.
  • a decompression cam 38 is fitted on a small diameter cylindrical portion 30 of the one-way clutch 29 so as to rotate.
  • Fig. 3 is an enlarged view of the one-way clutch 29, the decompression cam 38 and portions neighboring them shown in Fig. 2 .
  • Fig. 4 is a IV-IV section of Fig. 3 and Fig. 5 is V-V section of Fig. 3 .

  • the intake rocker arm 19 is formed with a normal rotation stopper 43 that engages with the engaging projection 41 to stop the decompression cam 38 when the decompression cam 38 rotates normally.
  • an ignition plug 45 is screwed to the cylinder head penetrating it so that an electrode 46 of the ignition plug 45 is projected into the combustion chamber 6.
  • the decompression cam 38 can rotate in reverse counterclockwise because reverse rotation torque transmitted to the decompression cam 38 from the one-way clutch 29 is large. Since the engaging projection 41 of the decompression cam 38 is stopped by the reverse rotation stopper 42 as shown in Fig. 1 , the decompression cam 38 is stopped. In this state, the bifurcated end portion 20a of the exhaust rocker arm 20 touches the cam nose 38a of the decompression cam 38 and the exhaust valve 10 is slightly opened.
  • the camshaft 13 also rotates normally clockwise and the exhaust cam 28 also rotates in the same direction.
  • the bifurcated end portion 20a of the exhaust rocker arm 20 touches the cam nose 38a of the decompression cam 38 to give the decompression cam 38 rotational resistance torque and the one-way clutch 29 is disconnected from the camshaft 13 so as to shut torque transmission, the decompression cam 38 is held in the stopped state shown in Fig. 1 .
  • the exhaust cam and the intake cam rotate together with the camshaft 13.
  • the decompression cam 38 rotates accompanied by the camshaft 13 only when the bifurcated end portion 20a of the exhaust rocker arm 20 is separated from the cam nose 38a of the decompression cam 38, namely by an angle corresponding to the cam angle of the exhaust cam 28.

  • the gentle slope portion 39b of the egg-shaped depression 39 of the decompression cam 38 is formed for mitigating shock when the decompression cam 38 is stopped by the normal rotation stopper 43.
  • Fig. 11 is a graph showing relation among cam lifts owing to the intake cam, the exhaust cam and the decompression cam and the crank angle.
  • IN is the lift of the intake cam
  • EX is the lift of the exhaust cam
  • DC is the lift of the decompression cam.
  • the exhaust valve opens influenced by either of lifts of the exhaust cam and the decompression cam which is larger. After the normal rotation is commenced, the exhaust valve is opened along the curve A-B-C-D-E-F-G-H-I-J.
  • the lift becomes zero when the above-mentioned accompanied rotation advances to some extent and the cam nose disengages from the bifurcated end portion of the exhaust rocker arm.
