せる。[Prior Art] Generally, in the drive mechanism of a hydrogen engine, for example, a carburetor type hydrogen engine, a container housing a hydrogen storage alloy is connected to the engine through a pipe, and the hydrogen storage alloy is heated to generate hydrogen. After the pressure of hydrogen gas is regulated by a regulator installed in the pipe, it is sent from the carburetor through the intake manifold into the combustion chamber, where it is ignited by a spark plug to explode and start the engine.

逆火を防止する技術が懸案となっている。[Problem to be solved by the invention] However, when the engine is stopped, the hydrogen gas flowing into the engine through the pipe is not burned and exhausted from the engine (in the regulator, carburetor brake, and engine intake manifold). Then, when the engine is started again, the hydrogen concentration at the start of ignition increases due to the accumulated hydrogen gas, causing an explosion outside the combustion chamber, so-called backfire.This backfire continues. If this happens, it can cause the engine to stall, so there is a concern about technology to prevent backfire during startup.

A method for starting the engine, wherein, prior to starting driving of the engine, the communication path between the storage container and the engine is shut off, and the supply of hydrogen gas to the engine is stopped, and the engine is started to combust while the communication path is blocked. The engine is idled to exhaust the hydrogen gas accumulated in the path leading to the chamber, and after the accumulated hydrogen gas has been exhausted, the communication passage is unblocked and hydrogen gas is supplied to the engine. The main point is to start the drive.

The engine is idled to exhaust the hydrogen gas that has accumulated between the passage blockage point and the combustion chamber of the engine. As a result, the accumulated hydrogen gas is removed when the engine is started, and an increase in hydrogen concentration is avoided.

行う。Furthermore, when a predetermined time (0.5 seconds) has elapsed in S5,
That is, when the spark plug 11 is in a state where it can completely ignite,
The controller 13 controls the engine rotation sensor 1 in S6.
Based on the signal from 6, it is checked whether the engine 9 is rotating reliably. That is, in this embodiment, this is to avoid supplying hydrogen gas to the engine 9 in a state where the starter 14 does not rotate and the engine 9 is not rotating due to overheating or the like. When it is determined that the engine 9 is rotating, the controller 13 outputs a signal to the electromagnetic control valve 5 at S7, energizes it, switches it from position b to position a, and connects the alloy tank 1 and engine 9. to allow hydrogen gas to flow to the engine 9 side. As a result, hydrogen gas is mixed with air in the carburetor 7, and then an initial explosion is performed in the combustion chamber of the engine 9, and the engine 9 starts to be driven. Note that when the engine 9 is not rotating in S6, the controller 13 assumes that the starter 14 or the like is out of order and performs other processing that will not be mentioned in this embodiment.

Then, the ignition of the spark plug 11 is stopped via the controller 13, the electromagnetic control valve 5 is switched from the a position to the b position, and the heating of the hydrogen storage alloy in the alloy tank 1 is stopped by an appropriate method. It will be done.
上記したように、本実施例においては、エンジ゛ン９の
駆動開始に先立ち、同エンジン９を空転させることによ
り、電磁制御弁５とエンジン９の燃焼室との間に滞留す

が確実に防止され得る。As described above, in this embodiment, prior to starting the engine 9, the engine 9 is idled to remove hydrogen gas remaining between the electromagnetic control valve 5 and the combustion chamber of the engine 9. Since the air is completely exhausted from the air outlet 9, backfire can be reliably prevented.
なお、本実施例ではコントローラ１３により電磁制御弁
５をａ、ｂ両位置に切換えて、合金タンク１とエンジン

行うようにすることも可能である。In this embodiment, the electromagnetic control valve 5 is switched to both positions a and b by the controller 13 to connect and disconnect the alloy tank 1 and the engine 9, but instead of this, when the engine 9 starts driving At times, the controller 13 may perform duty control on the electromagnetic control valve 5 to gradually increase the amount of hydrogen gas flowing into the combustion chamber to perform a smooth initial explosion.
また、前記実施例では点火できる状態で水素ガスを供給
する意味で、プラグ１１の点火後０．５秒待機したが、
これに限定されることなく、点火と同時又は直前に電磁
制御弁５を開いてもよく、要はエンジン始動時において

Without being limited to this, the electromagnetic control valve 5 may be opened at the same time as or just before ignition.The point is that when the engine is started, the hydrogen gas that had accumulated in the intake manifold, engine, etc. when the engine was stopped last time is exhausted. All that is required is a timing period for the fuel to be burned after the fuel is burned.
また、前記実施例では滞留している水素ガスの排気の有
無を時間に基いて行ったが、スタータによって回転され

よい。Further, in the above embodiment, whether or not the remaining hydrogen gas is exhausted is determined based on time, but the number of revolutions of the engine 9 rotated by the starter is detected, and the remaining hydrogen gas is detected based on the rotation. Alternatively, the presence or absence of exhaust gas may be determined.

A method for starting the engine using hydrogen gas released from the hydrogen storage alloy by communicating a container containing a hydrogen storage alloy with an engine, the method comprising: starting the engine; First, the communication path between the storage container and the engine is shut off, and while the supply of hydrogen gas to the engine is stopped, the hydrogen gas accumulated in the path from the point where the communication path is cut off to the combustion chamber of the engine is exhausted. A method for starting a hydrogen engine, which comprises idling the engine as much as possible, and, after exhausting the accumulated hydrogen gas, releasing the blockage of the communication passage, supplying hydrogen gas to the engine, and starting to drive the engine. .
