Abstract
The utility model discloses a piston of gas engine, which is composed of piston body and firebox on the top of the piston body. Bottom surface of the firebox parallel to upper head surface of the piston body is in a basin-shaped whose radius increases progressively from bottom to opening. Side and bottom surface of the firebox, the side of the firebox and the upper end surface of the piston body are connected in arc-shaped transition. The utility model is characterized in good suitability for gas engine so as to improve the working performance of the gas engine.
Description
Technical field
The utility model relates to a kind of technical field of gas engine, especially relates to the gas engine piston after a kind of improve.
Background technique
At present gas engine has been widely used in the middle of all trades and professions such as power, generating as the power equipment of a kind of not only economy but also environmental protection.Present gas engine piston mainly is that the piston by diesel engine is that prototyping forms, just only simple head to diesel engine piston carries out some transformations, be optimized as the size that will be the firing chamber of ω shape on the former diesel engine piston, to reduce the compression ratio of work combustion gas, but because gas engine is different with the working mechanism of diesel engine, so only simply the head of piston is transformed or the size of piston combustion bowl is carried out some changes, be difficult to adapt to the characteristics and the requirement of gas engine work, thereby the service behaviour of gas engine has been subjected to great restriction.
Summary of the invention
The technical problems to be solved in the utility model has provided a kind of gas engine piston, and it can be good at adapting to the work characteristics of gas engine, improves the service behaviour of gas engine.
For solving the problems of the technologies described above, the technical solution of the utility model is: the gas engine piston, comprise piston only, the firing chamber that the piston only top is provided with, the bottom surface of described firing chamber is parallel to the upper-end surface of piston only and is the peviform that radius is progressively increased to opening end by the bottom, is respectively circular-arc transition between the upper-end surface of the side of described firing chamber and the bottom surface of firing chamber and piston only.
As a kind of improvement, the side of described firing chamber and the upper-end surface of piston only are inclined to 70 °.
Adopt the gas engine piston of said structure, firing chamber by peviform structure on the piston only, and the arc transition of the slyness of the side of firing chamber and bottom surface and piston only upper-end surface, and the firing chamber has the opening greater than the bottom, can be so that mixed gas can enter into the firing chamber easily and burning fully in the firing chamber of gas engine, improve the working condition of gas engine, brought into play the maximum performance of gas engine.The side of firing chamber and the upper-end surface of piston only are inclined to 70 ° angle, can be so that mixed gas has a good combustion propagation environment in the firing chamber, improve the velocity of combustion of mixed gas, help the abundant burning of mixed gas, reduce the delivery temperature of motor.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
Accompanying drawing is a gas engine structure of piston schematic representation of the present utility model.
Embodiment
With reference to accompanying drawing, a kind of gas engine piston of the present utility model is: comprise the piston only 1 that is arranged in the gas engine cylinder, be provided with firing chamber 2 in the top depression of piston only 1, the bottom surface of firing chamber 2 is parallel to the upper-end surface of piston only 1, and firing chamber 2 is the peviform that radius is progressively increased to opening end by the bottom, in order to make mixed gas burning fully in firing chamber 2, to bring into play its maximum performance, be respectively circular-arc transition between the upper-end surface of the bottom surface of the side of firing chamber 2 and firing chamber 2 and piston only 1, like this, just can make things convenient for mixed gas flowing in the firing chamber, and it is 70 ° angle that the upper-end surface of the side of firing chamber 2 and piston only 1 can be designed to tilt, make mixed gas in the firing chamber, have a good combustion propagation environment, improve the velocity of combustion of mixed gas, help the abundant burning of mixed gas, reduce the delivery temperature of motor.And the opening of firing chamber 2 and the upper-end surface of piston only 1 are designed to 15 °, and reduced harmful clearance, for the flow burning speed that improves mixed gas, improve the effective output of motor, reduce the delivery temperature effect of being very helpful.
Claims (2)
1, gas engine piston, comprise piston only (1), the top of piston only (1) is provided with firing chamber (2), it is characterized in that: the bottom surface of described firing chamber (2) is parallel to the upper-end surface of piston only (1) and is the peviform that radius is progressively increased to opening end by the bottom, is respectively circular-arc transition between the bottom surface of the side of described firing chamber (2) and firing chamber (2) and the upper-end surface of piston only (1).
2, gas engine piston according to claim 1 is characterized in that: the upper-end surface of the side of described firing chamber (2) and piston only (1) is inclined to 70 °.
