Abstract
The invention discloses a supplying method and supplying device of gas fuel for fuel gas engine. It sets fuel gas intake channel on the cylinder cover, covering fuel gas sliding valve on valve stem. While supplying fuel gas, descending the gas intake gate, opening the gas intake gate, shut down the channel between fuel gas intake channel and fuel gas injecting pipeline, the fuel gas can't come into cylinder; continuing descending the gas intake gate, opening the channel between fuel gas intake channel and fuel gas injecting pipeline, the fuel gas comes into cylinder; the fuel gas intake gate rising until the fuel gas sliding valve superposing with the valve stem guide, the channel is shut down and stop supplying fuel gas; the fuel gas intake gate would continue rising until the gate fully shut down. The invention could lower engine heat load and improve output power of engine.
Description
Technical field:
The present invention relates to a kind of fuel feeding method and supplier of gas engine.
Background technique:
Traditional gas engine, gaseous fuel and air are supplied with inflammable mixture earlier in shared suction tude, press the valve timing of camshaft control then, and each cylinder is successively by supplying with inflammable mixture in the shared suction tude.This scheme key is to consider the valve timing of motor, and excessive valve overlap coupling meeting causes the suction tude tempering, light the inflammable mixture in the suction tude and blast, and along with the further raising of gas engine load.The tendency of tempering also can increase, thereby has limited the further raising of gas engine load.Simultaneously, because in " scavenging " process, inflammable mixture enters outlet pipe, easily produces the outlet pipe after-burning again, " blowing out " phenomenon takes place.So, adopt the gas engine of this scheme, all adopt the less port timing of valve overlap, but because " scavenging " process is shorter, will cause the heat load of motor too high, effective output reduces.
Summary of the invention:
The object of the present invention is to provide a kind of " scavenging " time, reduction engine heat load that can increase motor, make the supplying method and the supplier of the high gas fuel of gas engine of engine output.
Technical solution of the present invention is:
A kind of supplying method of gas fuel of gas engine, be included in air cavity is set on the cylinder cap, stem guide is set in the cylinder cap, intake valve is set in the stem guide, it is characterized in that: the combustion gas access that communicates with the stem guide inner chamber is set, the gas slide-valve that suit control exhaust gas nozzle port opens and closes on valve stem on cylinder cap; During fuel gas supply, at first intake valve is descending, IO Intake Valve Opens, and gas slide-valve is relative with valve guide bushing overlapping on the intake valve, the pathway closure between combustion gas access and the exhaust gas nozzle port, combustible gas can not enter cylinder by exhaust gas nozzle; Intake valve continues descending, the gas slide-valve DL synchronization, and the passage between combustion gas access and the exhaust gas nozzle port is opened, and combustible gas enters cylinder; Then, intake valve is oppositely up, and is relative again with valve guide bushing when overlapping when going upward to gas slide-valve, and the pathway closure between combustion gas access and the exhaust gas nozzle port, combustible gas stop again supplying with, and intake valve continues to go upward to intake valve and closes fully.
A kind of supplier of gas fuel of gas engine, be included in the air cavity that is provided with on the cylinder cap, stem guide is set in the cylinder cap, intake valve is set in the stem guide, it is characterized in that: the combustion gas access that communicates with the stem guide inner chamber is set, the gas slide-valve that suit control exhaust gas nozzle port opens and closes on valve stem on cylinder cap.
The present invention can enter combustible gas cylinder time and be controlled in the motor works fine scope, get rid of the possibility that has combustible gas in the air inlet and exhaust piper, avoid because of the excessive harmful effect that causes of valve overlap, " scavenging " time of increasing, reduce engine heat load, improve engine output.The present invention is applicable to all inflammable gass such as natural gas, oil field gas, coal-seam gas, gas, biogas, coking gas, liquefied petroleum gas.
Description of drawings:
The invention will be further described below in conjunction with drawings and Examples.
Accompanying drawing is the configuration diagram of the supplier of gas fuel of gas engine of the present invention.
Embodiment:
A kind of supplying method of gas fuel of gas engine and supplier, be included in air cavity 2 is set on the cylinder cap 1, stem guide 3 is set in the cylinder cap 1, intake valve 4 is set in the stem guide 3, the combustion gas access 5 that communicates with the stem guide inner chamber is set, the gas slide-valve 7 that suit control exhaust gas nozzle port opens and closes on valve stem 6 on cylinder cap 1; During fuel gas supply, at first intake valve 4 is descending, IO Intake Valve Opens, and gas slide-valve is relative with stem guide overlapping on the intake valve, the pathway closure between combustion gas access and the exhaust gas nozzle port 8, combustible gas can not enter cylinder by exhaust gas nozzle 9; Intake valve 4 continues descending, gas slide-valve 7 DL synchronizations, and the passage between combustion gas access and the exhaust gas nozzle port 8 is opened, and combustible gas enters cylinder; Then, intake valve 4 is oppositely up, and is relative again with stem guide 3 when overlapping when going upward to gas slide-valve 7, and the pathway closure between combustion gas access 5 and the exhaust gas nozzle port 8, combustible gas stop again supplying with, and intake valve 4 continues to go upward to intake valve and closes fully.
