The technical problem too small or excessive according to compression ratio in the prior art of above-mentioned proposition, and a kind of energy-saving piston is provided.
The technological means that the utility model adopts is as follows:
A kind of energy-saving piston, comprises piston crown and piston skirt, and described piston crown comprises a platform and be positioned at one on described platform protruding; Described projection comprises side one, side two, side three and side four; Described side one is 30 ° with the angle of described platform, described side one extends to described platform and forms a groove one on the platform, namely described side one and the bottom surface of described groove one are in same plane, and described groove one matches away from the side of described projection and the side of intake valve head; Described side two is 35 ° with the angle of described platform, described side two extends to described platform and forms a groove two on the platform, namely described side two and the bottom surface of described groove two are in same plane, described groove two matches away from the side of described projection and the side of exhaust valve head, described intake valve and the design of described exhaust valve side; Described side three matches with the inwall of firing chamber; Described side four is corresponding with spark plug;
Under working state, when described piston movement is to top dead center, described intake valve head and described groove one and described side one Spielpassung, described exhaust valve head and described groove two and described side two Spielpassung, described side three fits with described Inner Wall of Combustion Chamber, and described side four does not contact with described spark plug.
When described piston movement is to top dead center, the gap between described side four and described spark plug is 4.5mm.
The surrounding of described platform is provided with chamfering, and described chamfering is 18 °.
Described platform and described protruding cast inblock form.
The wall thickness of described piston crown is 4mm.
The utility model has the following advantages:
1, make to improve the compression ratio of mixed gas in firing chamber by protruding design, improve combustion efficiency;
2, the airflow thrust decomposition decreasing mixed gas burning and produce is set by the angle of side one and side two, improves combustion efficiency;
3, by cast inblock platform and projection, improve piston bulk strength;
4, by the wall thickness of limited piston head, alleviate the weight of piston, reduce the inertia of reciprocating motion of the pistons, improve the stability in piston movement process;
5, the energy consumption of the single-cylinder four-stroke motorcycle of energy-saving piston described in the utility model is used to reduce 10%-31%.
The utility model extensively can be promoted in fields such as single-cylinder four-stroke motorcycles for the foregoing reasons.
