The clean gas generating means 2 of the electric power of 3 supplies have 4 supplying clean gas of power device to power device 4 as a result,
Engine 5 cleaned.
As power supply 3, the power supply by socket can be, be also possible to mobile battery (battery) device, but
It is preferably to have the function of that the electric current of supply can be controlled.It is of course also possible to have clean gas generating means 2
Not power supply 3 can be made to have the function of this function that electric current is controlled.In addition, as power supply 3, according to generated
The viewpoint of gas flow and safety preferably makes the current flowing of 0.5A~30A, more preferably makes the current flowing of 2A~20A.
Power device 4 is the various power devices with the engine as internal combustion engine, such as can be applied to generate temperature
Mobile devices, the generators such as the steam locomotive (boiler) of water, automobile, rolling stock, ship, aircraft etc..
Power device 4 makes the power part connecting with engine 56 work and be acted as power device.For example, dynamic
In the case that power device 4 is automobile, power part 6 is the wheel of automobile, makes running car because of wheel rotation.
In engine cleaning processes of the invention, in the state of operating engine 5, supplied clearly for engine 5
Clean gas and engine is cleaned.According to the viewpoint of safety, preferably by the connection cutting of engine 5 and power part 6
State is directed to 5 supplying clean gas of engine in the state of dallying.
When being cleaned in the state of idle running to engine, can only carry out engine cleaning when temporarily will be clear
Clean gas generating device 2 is connect with power device 4, and tears clean gas generating means 2 open after the cleaning of engine terminates
Under.The cleaning of engine is carried out to more automobiles etc. thereby, it is possible to use 1 clean gas generating means 2.
Such as via hose etc. and from clean gas generating means 2 to the air inlet supplying clean gas of engine 5, and pass through
The clean gas is discharged by the exhaust portions such as silencer 7.
The cleaning of engine of the invention preferably lasts for progress 1 minute or more.Preferably, the capacity of engine more it is big then
The cleaning for more persistently carrying out engine for a long time, is more preferably sent out within time capacity [cc] × (0.1~1.0) second
The cleaning of motivation.
As shown in Fig. 2, clean gas generating means 2 are the electrolysis units for generating oxygen and hydrogen by electrolysis.Clearly
The cover 12 that clean gas generating device 2 has main part 11 and can remove from the main part 11.Electrolyte etc. in order to prevent
Leakage, the fixing piece that will preferably engage with each other are set to main part 11 and cover 12.
Anode electrode 13 and cathode electrode 14 are internally provided in main part 11.Have in cover 12 and connects with power supply 3

The bottleneck of plastic bottle equipped with electrolyte aqueous solution is inserted by formula, thus supplies electrolyte aqueous solution.It is of course also possible to by cover
12 remove and supply electrolyte.
Electrolyte aqueous solution is the aqueous solution so that when dissolution conductive, so-called electrolyte dissolution.As used
Electrolyte is not particularly limited, however, it is preferred to will not generate the metal protections such as chlorine when gasifying by electrolysis
The electrolyte of gas, virose gas.
It as preferred electrolyte, such as can enumerate: sodium hydroxide, potassium hydroxide, sodium carbonate, potassium carbonate, sodium sulphate, carbon
Sour hydrogen sodium etc..As electrolyte, it can be used only a kind in above-mentioned substance, it can also be appropriate by above-mentioned substance of more than two kinds
Ground mixing.
As electrolyte aqueous solution, if make the electric power supplied by power supply 3 circulate, for electrolyte concentration simultaneously
It is not limited, still, considers from the balance being powered with generated gas flow, preferably comprise 0.1~10.0 weight %'s
Electrolyte, the further preferably electrolyte of 0.5~5.0 weight %.In addition, being set as in concentration using hydrate
Hydration section (H is not considered2O hydrate).
It as water used in electrolyte aqueous solution, is not particularly limited, tap water, soft water, hard can be used
Water, pure water etc., still, according to the viewpoint controlled the gas of generation, it is preferable to use few as far as possible pure of the impurity such as Purified Water
Water.
Preferred electrolyte aqueous solution is filled in main part 11 to defined water level.It is filled as a result, being generated in clean gas
The inside for setting 2 forms the filling region 21 filled with electrolyte aqueous solution and the gas zones 22 as gas blanket.
When electric current circulates in electrolyte aqueous solution, oxygen and hydrogen are generated with the ratio of 1:2, also, mixed
Produce the gas from electrolyte.For example, in the case where sodium carbonate is used as electrolyte, in addition to hydrogen and oxygen with
Outside, carbon dioxide, also, sodium and bottom unvaporized but that filling region 21 is precipitated in the form of sediment are also generated.Separately
On the one hand, the decomposition gas generated by electrolysis is stored in gas zones 22.
It is connect for example, by hose etc. with engine 5 in the outlet 19 for being set to cover 12.5 intake-gas of engine
Gas contained in region 22 makes fuel combustion using the gas and itself to operate as clean gas.It is covering
Portion 12 is formed with outside air suction inlet 17.Therefore, engine 5 is aspirated according to aequum containing decomposing gas and air
Clean gas.
Engine 5 makes fuel combustion using clean gas.At this point, containing the life generated by electrolysis in clean gas
At gas, therefore, compared with common air, the concentration of oxygen and hydrogen is higher.It is to be understood that the oxidation due to oxygen is made
It is stronger with relatively strong and hydrogen reduction, therefore, so that it is attached to the decomposition such as unburned residue of the inside of engine 5,
As a result, being cleaned to engine 5.
In addition, in main part 11, have electrolyte aqueous solution in side away from the closer position in bottom surface or in bottom surface
The Drainage Division (drain) 18 of discharge.It can be drained from the lower part of main part 11, thereby, it is possible to will sink while draining
Starch removes, so as to easily clean to main part 11.
In this way, using the clean gas containing the decomposition gas generated by clean gas generating means 2 for engine 5
And fuel is made to burn in Time constant, thereby, it is possible to carry out the cleaning of engine 5.
