Abstract
A scavenge system for a two cycle internal combustion engine that includes separate scavenge manifolds and riser scavenge passages extending therefrom to the individual scavenge ports so as to permit the establishment of a desired flow pattern within the engine without the flow to one scavenge port interfering with the flow to the other scavenge ports.
Claims34
A scavenge system for a two cycle internal combustion engine comprising a cylinder having a bore in which a piston reciprocates, a first scavenge port formed in said cylinder for admitting a charge into said bore, a second scavenge port formed in said cylinder for admitting a charge into said bore, a first scavenge manifold extending at least in part around said cylinder bore, a second scavenge manifold extending at least in part around said cylinder bore, a first scavenge riser passage extending from said first scavenge manifold to only said first scavenge port, a second riser scavenge passage extending from said second scavenge manifold to only said second scavenge port, and a source of air communicating with said first and said second scavenge manifolds.
A scavenge system for a two cycle internal combustion engine comprising a cylinder having a bore in which a piston reciprocates, a first scavenge port formed in said cylinder for admitting a charge into said bore, a second scavenge port formed in said cylinder for admitting a charge into said bore, a third scavenge port formed in said cylinder for admitting a charge into said bore, a first scavenge manifold, a second scavenge manifold, a third scavenge manifold, a first scavenge riser passage extending from said first scavenge manifold to said first scavenge port, a second rise scavenge passage extending from said second scavenge manifold to said second scavenge port, a third scavenge riser passage extending form said third manifold to said third scavenge port, and a source of air communicating with said first, second and third scavenge manifolds.
