Open intake and exhaust chamber constructions for an air handling system of an opposed-piston engine

摘要

An opposed-piston engine has a cylinder block with a plurality of cylinders arranged inline, with each cylinder including an intake port longitudinally separated from an exhaust port. The engine's air handling system includes open intake and exhaust chambers in the cylinder block. The open chamber constructions eliminate the need for multi-pipe manifolds and smooth the flow of charge air.

1. An air handling system for an opposed-piston engine having a cylinder block with a plurality of cylinders arranged inline, in which each of the plurality of cylinders includes an inlet port longitudinally separated from a cylinder exhaust port, comprising:
an exhaust chamber within the cylinder block including at least one exhaust outlet opening through the cylinder block; all of the cylinder exhaust ports being contained in the exhaust chamber to discharge exhaust thereinto; and, at least one exhaust deflector situated in the exhaust chamber, between adjacent the cylinder exhaust ports, and including surfaces angled to deflect exhaust being discharged into the exhaust chamber from the exhaust port of one cylinder away from the cylinder exhaust port of an adjacent cylinder.
