Abstract
The utility model provides a gas engine cylinder cover, which comprises a cylinder cover body and combustion chamber upper walls, wherein a gas inlet opening and an exhaust opening are arranged on the combustion chamber upper walls, the gas inlet opening is communicated with a gas inlet passage arranged on the cylinder cover body, the exhaust opening is communicated with an exhaust passage arranged on the cylinder cover body, and oil spray nozzle installing holes are arranged on the combustion chamber upper walls. The gas engine cylinder cover is characterized in that a spark plug installing hole is arranged on a position corresponding to each oil spray nozzle installing hole, and one or two spark plug installing holes are arranged on each combustion chamber upper wall. The gas engine cylinder cover has the advantages that the gas engine cylinder cover can adapt to the gas requirement, and the combustion performance and the tail gas emission are further improved.
Description
Technical field
The utility model relates to a kind of engine cylinder cover, particularly relates to a kind of cylinder cap that is used for gas engine.
Background technique
At present, mostly domestic gas engine is on the DENG basis, to reequip, and DENG is to adopt the compression ignite mode; Do not possess ignition mechanism; And the cylinder cap of ordinary diesel oil motor is designed by the liquid fluid fuel of use such as gasoline, diesel oil etc., does not consider the particularity of combustion gas.Cause the combustion performance of engine gas not good, exhaust emissions is not up to standard, pollute defectives such as increase.
The model utility content
The purpose of the utility model is to overcome the common engine cylinder cap can not adapt to deficiencys such as combustion gas needs, combustion performance are not good, exhaust emissions is not up to standard, pollution increase, and a kind of gas engine cylinder cap that adapts to the combustion gas needs, improves combustion performance and exhaust emissions is provided.
The purpose of the utility model reaches through following technical measures:
A kind of gas engine cylinder cap; Comprise cylinder body, firing chamber upper wall; The firing chamber upper wall is provided with suction port and relief opening, and suction port communicates with intake duct on the cylinder body, and relief opening communicates with air outlet flue on the cylinder body; The firing chamber upper wall is provided with the oil nozzle mounting hole, it is characterized in that: said each oil nozzle mounting hole correspondence is provided with a spark plug mounting hole.
Say that further said each firing chamber upper wall is provided with one or two spark plug mounting hole.
Owing to adopted technique scheme, compared with prior art, the utility model has the advantages that:
(1) can adapt to the combustion gas needs;
(2) further improve combustion performance and exhaust emissions.
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Description of drawings
Accompanying drawing 1 is the sectional view of a kind of gas engine cylinder cap of the utility model;
Accompanying drawing 2 be in the accompanying drawing 1 A-A to sectional view.
Embodiment
Embodiment: shown in accompanying drawing 1 and accompanying drawing 2; A kind of gas engine cylinder cap comprises cylinder body 2, firing chamber upper wall 6, and firing chamber upper wall 6 is provided with suction port 8 and relief opening 7; Suction port 8 communicates with intake duct 5 on the cylinder body 2; Relief opening 7 communicates with air outlet flue 1 on the cylinder body 2, and firing chamber upper wall 6 is provided with oil nozzle mounting hole 3, and each oil nozzle mounting hole 3 correspondence is provided with a spark plug mounting hole 4.Each firing chamber upper wall 6 is provided with one or two spark plug mounting hole 4.
The utlity model has the advantage that can adapt to the combustion gas needs and further improve combustion performance and exhaust emissions.
