  • METHODS AND SYSTEMS FOR MANAGING A CLEARANCE GAP IN A PISTON ENGINE
    Publication number: 20130167717
    Abstract: A piston engine may include a piston assembly, which may include a piston having a self-centering feature. The piston assembly may be configured to translate in a bore of the cylinder, and contact a combustion section and/or gas driver section. The self-centering feature may use a flow of blow-by gas in a clearance gap to provide a self-centering force on the piston assembly. The self-centering feature may include one or more slotted pockets, a step, a tapered portion, any other suitable feature, or a combination thereof. Optionally, a piston assembly may include a feature that aids in self-centering such as, for example, a labyrinth seal.
