Analysis Of Piston Secondary Motion
In an internal combustion engme, the piston performs secondary motion besides the primary reciprocating motion. The clearance between the piston skirt and cylinder liner allows the piston to move in the lateral direction and rotational motion about the piston pin axis. The piston secondary motion...

| description | In an internal combustion engme, the piston performs secondary motion
besides the primary reciprocating motion. The clearance between the piston skirt and
cylinder liner allows the piston to move in the lateral direction and rotational motion
about the piston pin axis. The piston secondary motion created impact between the
piston skirt and the cylinder liner that radiates unwanted engine noise and increases
friction loss. A measurement system consists of three laser displacements sensors are
developed to capture the instantaneous piston motion and posture directly from the
piston assembly under motorized condition. The laser spots aimed at the piston
crown with machined profile in order to obtain the rotational and lateral motion of
the piston. The instantaneous piston motion showed that the likelihood of contact
between the piston skirt and the cylinder liner increases with the occurrence of the
piston secondary motion. In addition, a non-linear model of the piston with
reciprocating, lateral and rotational degree of freedom is developed to investigate the
piston secondary motion and the piston slap induced vibration behavior of the single
cylinder engine. |
