Embodiment Construction
[0036] Please see image 3 , which is a half-sectional view of a piston used in a two-stroke single-cylinder gasoline engine provided by the first embodiment of the present invention.
[0037]The piston includes two parts, a crown 1 and a piston seat 2, which are made separately and connected into a whole through a connecting structure. The specific connection structure may be screwed or welded. It is best to use a connection with a certain degree of freedom, so that the relative position of the crown 1 and the piston seat 2 can be adjusted to a certain extent, reducing the stress on the two parts during processing. Concentricity requirements.
[0038] The role of the crown 1 is equivalent to the piston in the commonly used crank-link mechanism engine, and the role of the piston seat 2 has two: first, the piston seat 2 provides accommodating holes for the installation of the slider; secondly, the piston seat 2 Piston seat 2 is also the scavenging piston of two-stroke engine ...
