Besides, the in-cylinder injection type gas internal combustion engine cover is mainly applied to the gas internal combustion engine.
Description
Technical field
The utility model relates to gas internal-combustion engine cylinder cap, particularly a kind of cylinder injection type gas internal-combustion engine cylinder cap.
Background technique
Traditional gas engine cylinder cap, its structure is the outer mixed construction of cylinder, what enter cylinder cap intake duct is the mixed gas of combustion gas and air.The cylinder cap of this structure is that effect has been brought into play in the operation of gas engine, but it exists following shortcoming or deficiency simultaneously: 1. in the course of the work, gaseous fuel and air are generally to enter cylinder combustion acting after mixing outside firing chamber; 2. in the time using the higher gas of hydrogen content to make fuel as water gas, coking gas, Straw Gas, because the combustion of hydrogen speed in fuel is a lot of soon compared with other gas (as rock gas), in engine working process, very easily the hydrogen in suction tude is ignited, cause suction tude tempering to be blown out; 3. cylinder, row's temperature are prone to and climb sharply, and suction tude, air filter and near cable can be burnt out not in time as processed, and even cause whole motor damage.4. because mixing cylinder cap outward, cylinder easily cause suction tude tempering to blow out, cannot enriching density of hydrogen, and cause existing fuel gas generation unit continuous service output lower.
Summary of the invention
The purpose of this utility model is to provide a kind of cylinder injection type gas internal-combustion engine cylinder cap, adopts gas header pipe to be connected with gas control valve, fuel gas injection bend pipe, gas valve seat and combustion gas door; The absolute construction that air header, cylinder cap air inlet chamber are connected with air gate, effectively overcomes or avoids the shortcoming or the deficiency that in above-mentioned prior art, exist.
Cylinder injection type gas internal-combustion engine cylinder cap described in the utility model, comprises gas header pipe, gas control valve, air header, fuel gas injection bend pipe, cylinder cap air inlet chamber, combustion gas door, gas valve seat, cylinder body.On described cylinder body, air header is installed, on this air header, gas control valve is installed, gas control valve upper end is provided with gas header pipe, gas header pipe is through air header, lower end is installed and is connected with fuel gas injection bend pipe, this fuel gas injection bend pipe is connected with the gas valve seat and the combustion gas door that are installed on cylinder body, and described air header is connected with the air gate being installed on cylinder body.
Wherein
,described fuel gas injection bend pipe is connected with gas control valve by air header one end, and the other end is connected with the gas valve seat of installing on cylinder body.The installation joint of described gas control valve and fuel gas injection bend pipe is provided with cone tank and Sealing.Described air header is connected with the air gate being installed on cylinder body by cylinder cap air inlet chamber.
The utility model compared with prior art tool has the following advantages:
1, combustion gas and air direct cylinder injection, there is not flammable mixed gas outward in cylinder, thoroughly solves suction tude tempering problem;
2, cylinder cap has 2 intake valves, wherein isolates by valve seat air-inlet cavity and air cavity near an intake valve of cylinder cap air inlet end face, in order to enter combustion gas; Away from another intake valve of cylinder cap air inlet end face in order to enter air.Fuel tube and air duct are in cylinder isolation completely outward, and guiding gas and air directly spray into firing chamber respectively, stop the possibility of cylinder external burning;
3, on single cylinder burning line, gas control valve is set, in order to regulate single cylinder gas supply amount, solves the gas internal-combustion engine single cylinder unbalanced problem of doing work, make cylinder temperature, row's temperature more even;
4, when fuel tube is through air duct, adopt cone tank and O type rubber seal rings for seal, spray bend pipe and can move freely in mounting hole, Installation Flexibility is good, and sealing is reliable;
5, thoroughly stop gas internal-combustion engine suction tude tempering problem, make to make full use of as motor fuel in the widely used water gas of other production field, coking gas, Straw Gas, the contour hydrogen physical efficiency of cracking gas, expand the application area of gas engine, also saved the energy;
6, intake duct is thoroughly isolated combustion gas and air, makes gas engine in the time that the higher gases of hydrogen content such as using water gas, coking gas, Straw Gas is made fuel, and suction tude is avoided tempering.
Brief description of the drawings
Fig. 1 is a kind of example structure schematic diagram of the present utility model.
Embodiment
Consult Fig. 1, a kind of cylinder injection type gas internal-combustion engine cylinder cap, comprises gas header pipe 1, gas control valve 2, air header 4, fuel gas injection bend pipe 5, cylinder cap air inlet chamber 6, combustion gas door 7, gas valve seat 8, cylinder body 9.Air header 4 is installed on cylinder body 9, on this air header 4, gas control valve 2 is installed, gas control valve 2 upper ends are provided with gas header pipe 1, gas header pipe 1 is through air header 4, lower end is installed and is connected with fuel gas injection bend pipe 5, this fuel gas injection bend pipe 5 is connected with the gas valve seat 8 and the combustion gas door 7 that are installed on cylinder body 9, and described air header 4 is connected with the air gate being installed on cylinder body 9.
