| description | To realize a two-stroke opposite piston engine having high durability and less heat loss.SOLUTION: A two-stroke opposite piston engine (1) is formed with an exhaust port (2g) and an intake port (2h) in the entire circumferential region of a bore (2a) of a cylinder (2), and does not comprise a rib connecting the opposite edges of the bore (2a) in an extending direction of the exhaust port (2g) and the intake port (2h). Here, the engine comprises a ring (24) inserted into a ring groove (21c) formed on the outer peripheral surface of a piston. With the ring (24) inserted in the ring groove (21c), the ring (24) exerts contractile force inward in a radial direction of the ring groove (21c), and with the ring (24) contracted, the outer diameter of the ring (24) is preferably smaller or the same as the diameter of the piston.SELECTED DRAWING: Figure 1
【課題】耐久性が高く、また、熱損失の少ない、２ストローク式対向ピストンエンジンを実現する。【解決手段】本発明の一形態に係る２ストローク式対向ピストンエンジン（１）は、シリンダ（２）のボア（２ａ）の周方向全域に排気ポート（２ｇ）及び吸気ポート（２ｈ）が形成され、排気ポート（２ｇ）及び吸気ポート（２ｈ）におけるボア（２ａ）の延在方向で対向する縁部を接続するリブを備えていない。ここで、ピストンの外周面に形成されたリング溝（２１ｃ）に挿入されるリング（２４）を備え、リング（２４）がリング溝（２１ｃ）に挿入された状態で、リング（２４）は、リング溝（２１ｃ）の径方向内側に向かって収縮力を発現し、リング（２４）が収縮した状態で、リング（２４）の外径は、ピストンの直径に対して小さい又は同じであることが好ましい。【選択図】図１ |
