Its each cylinder power equalization, efficiency are improved.
The content of the invention
The purpose of the present invention is to realize that when inlet valve is opened air inlet and gaseous mixture air inlet are successively carried out, and makes gaseous mixture
The gas retarded admission of air inlet pipe（It is introduced into air）.Gas pressure of the gas pressure of air intake duct more than gaseous mixture air inlet pipe
Power, when inlet valve is opened, the air of air intake duct first enters combustor in advance, makes combustor surrounding have individual air film,
After inlet valve is opened to a certain extent, tow channel gas are inflated into cylinder again simultaneously, when inlet valve is close to and closes, inlet valve aditus laryngis
There is individual compressional wave, make the gas of gaseous mixture air inlet pipe compressed, along with the air pressure of air intake duct is more than gaseous mixture air inlet pipe
Air pressure, makes the gas circuit of gaseous mixture air inlet pipe close under the dual function of two kinds of pressure in advance.
Pressure servo regulating valve is disposed with gaseous mixture air inlet pipe, during the retarded admission of the gas for adjusting gaseous mixture air inlet pipe
Between.
A kind of four stroke gas engine air inlet methods, it is characterised in that include：
When inlet valve is opened, the air of air intake duct first initially enters combustor by auxiliary air flue, opens in inlet valve
After to a certain extent, the gaseous mixture of gaseous mixture air inlet pipe is mixed by the air of main airway and auxiliary air flue to be inflated into cylinder,
Inlet valve is close to when closing, and the gas circuit of main airway is closed in advance.
Described four stroke gas engine air inlet method of one kind, it is characterised in that also include：
Pressure transmission pipe sends the gas pressure of ad-hoc location in main airway to pressure transducer, the letter of pressure transducer
Number control electric butterfly valve adjusts the gas flow of the gas flow main airway in gaseous mixture air inlet pipe.
A kind of four stroke gas engine air intake installations, is characterized in that：Inlet valve is provided with main airway and auxiliary air flue two
Inlet channel, main airway are connected with gaseous mixture air inlet pipe, and auxiliary air flue is connected with air intake duct, and auxiliary air flue is wrapped in main airway.
Described four stroke gas engine air intake installation of one kind, is characterized in that：Main airway and gaseous mixture air inlet pipe pass through
One electric butterfly valve is connected, and pressure transmission pipe is arranged in main airway, and pressure transmission pipe connection sensor, the electric butterfly valve are controlled by
The signal of the sensor.
The invention has the beneficial effects as follows：Reduce electromotor row's temperature, improve air utilization ratio, realize that engine power is strengthened
With reduction discharge dual function.
