[Industrial applications]

 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a manual engine, and more particularly, to an internal combustion engine that prevents a risk caused by unintentional reverse rotation of a handle at the time of starting the engine.

[0002]

[Prior art]

 Conventionally, internal combustion engines that use gasoline or light oil as fuel have been widely used, and many engines are started by an electric motor.In the case of a simple engine, for example, a simple cultivator, tractor or In the case of small vessels, etc., a manual engine is often used.

In the case of these manual engines, as shown in the outline of FIG. 1, the decompressor 2 for releasing the pressure in the cylinder with the left hand 1 is rotated to the upper left to open the inside of the cylinder, and While keeping the state, with the right hand 3, the handle 4 that reciprocates the piston is rapidly rotated clockwise to give momentum to the flywheel, and when the momentum is gained, the decompression lever 2 is released and the cylinder is closed and rotated several times. Then, the fuel in the cylinder is compression-ignited and started.

[0004]

[Problems that the device is trying to solve]

 When the handle 4 is rotated with the decompressor 2 released at the time of starting the engine, if the operator is weak or the timing for releasing the decompressor 2 is bad, the reaction of compressed gas in the cylinder may occur. , The handle 4 may rotate in the reverse direction. When such a reverse rotation of the handle 4 occurs, the left hand 1 is at the decompression lever 2 position and the right hand 3 is at the handle 4 position at the same time. Since the operator's face is near the handle 4, there is a problem that the handle 4 rotating in the reverse direction may cause serious injury to the face.

Of course, the above problems have been solved in the case of an engine which may be relatively expensive, but have not yet been solved in the case of an inexpensive engine for cost reasons. SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a novel engine which avoids the danger caused by the reverse rotation of the handle as described above in a manual engine without cost.

[0006]

[Means for solving problems]

 The above object is achieved by the present invention described below. That is, the present invention operates the degassing decompressor at the time of starting to open the inside of the cylinder, accelerates the piston motion in the cylinder by the rotating handle, and releases the decompressor when the rotating force of the handle is applied. The engine is characterized in that the decompressor is provided with means for remotely operating the lever, in an engine that closes the gas vent valve and ignites by using the rotational force when the valve is opened.

[0007]

[Action]

 By allowing the decompressor of the manual engine to be operated remotely, the posture when the start handle is rotated will change from the conventional mid-waist state to a standing state, so it is possible that the handle will rotate backwards. However, there is no longer any risk of injury to the face due to the reverse rotation of the handle.

[0008]

【Example】

 The present invention will be described in more detail with reference to the preferred embodiments shown in the drawings. FIG. 1 is a diagram for explaining a state in which a conventional manual engine of a simple tiller is started. As shown in FIG. 1, a left hand 1 is used to release a decompression lever 2 for releasing pressure in a cylinder to the upper left. Rotate to open the inside of the cylinder. While keeping that state, with the right hand 3, the handle 4 for reciprocating the piston is rapidly rotated clockwise to give momentum to the flywheel. When the momentum is gained, the decompressor 2 is released and the cylinder is closed to rotate several times to start compression ignition of the fuel in the cylinder.

FIG. 2 shows a part of the engine to which the decompressor 2 is attached. The shaft of the decompressor 2 is connected to a valve that opens and closes the inside of the cylinder. By rotating the lever 2 to the upper left, the valve interlocking with the shaft is opened, and the piston can freely reciprocate in the cylinder. The lever 2 returns to its original state by a spring when it is released from the hand, closes the interlocking valve, and applies pressure to the cylinder.

FIG. 3 shows an embodiment of the present invention. One end of a rod-like object 5 that is bent at two places is fixed to the inside of the lever 2, and a member 6 that abuts on the surface of the outer shell of the engine is provided at the other end. The rod-shaped object has bending points a and b provided at two places, and the bending points a and b are connected by hinges a and b so that the rod-shaped object 5 cannot be bent further upward. A string 7 is connected near the member 6 of the rod.

In FIG. 4, the member 6 at the end of the rod 5 is brought into contact with the outer shell of the engine, the lever 2 is rotated to the upper left, and the degassing valve of the cylinder is opened. In this state, hold the string-like object 7 in the left hand, rotate the handle 4 with the right hand, and pull the string-like object 7 toward you at an appropriate timing, so that the end 6 that is in contact with the outer shell of the engine is It is designed to come off the outer shell of the engine.

The operation of the engine provided with the above remote control means 5 to 7 will be described. First, with respect to the engine in the state shown in FIG. 3, the end 6 of the rod-shaped object 5 is lifted and the end 6 is lifted. As shown in FIG. 4, it contacts the outer shell of the engine. In this state, the decompression lever 2 is rotated in the upper left direction by the tensioning action of the rod-like object 5, and the degassing valve interlocked with the decompression bar 2 is kept open. In this state, hold the end of the string 7 in your left hand and rapidly rotate the starting handle 4 with your right hand (see Fig. 1). By increasing the turning force of the handle 4 and pulling the string 7 of the left hand toward you in a timely manner in that state, the end 6 of the rod-like object 5 comes off the outer shell of the engine, and at the same time, the lever 2 restores to its original position. . The degassing valve is closed in conjunction with the lever 2, the atomized fuel in the cylinder is compressed and ignited, and the engine is started.

When the engine is started, the left hand can be placed at any position, so that the operator who rotates the handle does not have to be in the middle waist as in the conventional case, but must rotate the handle. The handle itself is easy, and even if the lever 2 is released at a bad timing and the handle rotates in the reverse direction, the handle will not injure the face or the like.

The present invention has been described above with reference to the illustrated embodiment. However, as described above, the lever 2 can be remotely operated to close the degassing valve connected to the cylinder. However, the present invention is not limited to the above-described embodiment. For example, the decompressor 2 may be pulled from the left direction and the pulling force may be released without touching the decompressor 2. Further, if a means for keeping the lever 2 in the open state is formed by using a shape memory alloy or an elastic body, and if it is automatically wound around the lever 2 when not in use, a rod-shaped object or a string-shaped object will interfere. It never happens.

[0015]

【effect】

 According to the present invention as described above, since the decompressor of the manual engine can be operated remotely, the posture when the starting handle is rotated is changed from the conventional middle waist state to the standing state. Even if the handle rotates in the reverse direction, there is no risk of injury to the face due to the reverse rotation of the handle.
