On, the outlet of the gas hose is towards the junction of the air flue and engine cylinder-body.So natural gas enter air flue when not
Frontal impact can be produced with the air in inlet manifold, so as to reduce the resistance of air-flow, the fuel gas of mixing can quickly enter
Enter into engine cylinder body；And inclination connection can also reduce the height of air intake structure, so as to reduce the volume of whole engine.
In the air intake structure of above-mentioned dual fuel engine, the air flue quantity of the inlet manifold is four, the combustion
The quantity of gas flexible pipe is also four, and one end of the gas hose is connected with the distributing valve, four gas hoses it is another
One end is connected with four air flues respectively.Air intake structure correspondence four cylinder engine in the technical program, this engine type
With commonplace, fuel gas respectively enters four air flues by gas hose, is then directly entered again in different cylinder bodies,
The distribution of fuel gas is more uniform reliable.
In the air intake structure of above-mentioned dual fuel engine, the connection for also having connection controller on the distributing valve connects
Head.It is connected by the jointing with independent ECU, combustion gas is controlled.
Compared with prior art, it is by optimizing the air inlet dependency structure of combustion gas in the utility model, gas hose is direct
It is connected on the air flue of inlet manifold, natural gas enters combustion chamber and carries out burning release energy after quickly being mixed with air
Amount, the air inlet dependency structure of combustion gas and the air intake structure of available engine are merged well so that dual fuel engine
Overall volume is smaller, using reliable.
