- a reverse rotation preventing mechanism for preventing reverse rotation is provided on a cam shaft that opens and closes an intake valve or an exhaust valve (for example, see Patent Document 1).
- Patent Document 1 Japanese Patent Application Laid-Open No. 6-146938
- the problem to be solved is to configure a reverse rotation prevention mechanism by changing the cam shape of the fuel injection pump cam, and to provide a diesel engine with a reverse rotation that may occur at startup. It is to prevent.
- the reverse rotation prevention mechanism for a diesel engine of the present invention drives a camshaft via a power transmission means by a crankshaft, and drives a fuel injection pump, an intake valve, and an exhaust valve on the camshaft.
- a middle portion having a larger diameter than the smallest diameter portion is formed at a predetermined angle on the rear side in the rotation direction with respect to the largest diameter portion of the fuel injection pump cam.
- the height of the middle portion is configured to be substantially the same as the height of the plunger when the fuel injection pump driven by the cam stops the injection at the time of starting. Things.
- the height of the middle portion is set so as not to interfere with the rotation locus of the leading end of the connecting rod.
- the position where the middle portion changes to the small diameter portion is formed near the position where the intake valve starts to open.
- a position where the diameter gradually decreases from the maximum diameter portion to a middle portion is formed near a position where the exhaust valve starts to open.
- a camshaft is driven by a crankshaft via power transmission means, and a fuel injection pump, an intake valve, and an exhaust valve are respectively driven on the camshaft.
- the maximum diameter partial force of the cam for the fuel injection pump is formed at a predetermined angle on the rear side in the rotation direction, and the middle portion having a larger diameter than the minimum diameter portion is formed at a predetermined angle.
- the height of the middle portion is configured to be substantially the same as the height of the plunger when the fuel injection pump driven by the cam terminates the injection at the time of starting. Therefore, even if the engine rotates in the reverse direction at the time of starting, the fuel is hardly sent from the fuel injection pump into the cylinder, so that there is no combustion. Therefore, the force S for preventing reverse rotation can be obtained.
- the reverse rotation prevention mechanism for a diesel engine of the present invention since the height of the middle portion does not interfere with the rotation locus of the leading end of the connecting rod, the crankshaft and the camshaft are arranged as close as possible. Therefore, the engine can be made compact.
- the position where the middle portion changes to the small diameter portion is formed near the position where the intake valve starts to open. Since the intake valve is open even after the fuel injection ends at the position where the fuel changes to the middle stage, the fuel can no longer be sucked into the cylinder and combustion can be prevented. Therefore, the continuation of the reverse rotation can be prevented, and the reverse rotation of the engine at the time of starting can be prevented.

- the range of the inclined portion 63 is configured so as to substantially correspond to the position from the first opening of the intake valve 31 in the profile 65 of the intake cam 21 to the most opened position. More specifically, the lift amount L2 in FIG. 6 is such that the plunger 43 contracts at the time of startup and starts to compress, the pressure of the fuel in the plunger barrel 45 increases, and the plunger barrel 45 and the high-pressure pipe 47 This is a position to open the outlet valve 48 disposed between them, and the range from the lift amount L2 to L1 corresponds to the injection amount at the start. in this way This configuration prevents the reverse rotation by minimizing the pressure feed of the fuel during the later-described reverse rotation.
- the fuel injection pump cam 14 is configured so that the lift amount that has risen during the lift lift period 71 falls in two steps, the first downward lift period 72 and the second downward lift period 73. Has been established.
- the fuel is injected when the intake valve 31 is near the end of the closing operation.
- the amount of fuel discharged from the intake port 7a and the amount of fuel sucked into the cylinder 2a is so small that the amount of fuel required for combustion does not reach the amount required for combustion. Therefore, the continuation of the reverse rotation can be prevented, and the reverse rotation at the time of starting can be prevented. At this time, since the piston 4 is in the process of ascending, only a small amount of force can enter the cylinder 2a.
- the height of the middle section 53 is configured to be substantially the same as the height of the plunger 43 when the fuel injection pump 12 finishes the injection, the fuel injection pump The injection amount of the fuel before the compression top by the fuel injection pump 12 becomes small, and the fuel is hardly sent from the fuel injection pump 12 to the combustion chamber of the cylinder 2a. Therefore, no combustion occurs in the combustion chamber, and the reverse rotation cannot be continued, so that the reverse rotation can be prevented. Further, after the fuel injection is completed, the roller 42 comes into contact with the middle portion 53 of the fuel injection pump cam 14, and during the period in which the roller 42 is in contact with the middle portion 53, the exhaust power 22 The exhaust valve 32 is configured to be opened and closed by the profile 66 of FIG.
- the camshaft 13 is driven from the crankshaft 5 via the power transmission means, and the cams 14 and 21 which drive the fuel injection pump 12, the intake valve 31 and the exhaust valve 32 on the camshaft 13.
- the middle stage portion 53 having a larger diameter than the minimum diameter portion 51 at a predetermined angle R3 behind the maximum diameter portion 52 of the fuel injection pump cam 14 in the rotational direction from the maximum diameter portion 52, Even if the crankshaft 5 rotates in the reverse direction, the amount of fuel remaining in the cylinder 2a will not be reduced and combustion will not occur, so that the reverse rotation can be prevented from continuing.
