Title:

往復動エンジンのシリンダライナおよびピストンの堆積物を制御するためのシステム

Document Type and Number:

Japanese Patent JP6666533

Kind Code:

B2

Abstract:

A system (10) includes a reciprocating engine (12) having a cylinder liner (42) and a piston (24) disposed within the cylinder liner. The cylinder liner includes an inner wall (44) and extends around a cavity (46). The inner wall includes a first axial end (86), a second axial end (88), a piston travel portion (90), and a top portion (92). The top portion is nearer to the first axial end of the cylinder liner than to the second axial end of the cylinder liner. The top portion has a first surface finish with a first roughness average (Ra 1 ) greater than approximately 2 µm and a total waviness (Wt) less than approximately 0.1 mm. The piston is configured to move in a reciprocating manner within the cylinder liner. The piston includes a top land configured to be radially opposite the top portion of the inner wall of the cylinder liner when the piston is at a top dead center position.
