Title
(EN) AIR HANDLING IN A HEAVY-DUTY OPPOSED-PISTON ENGINE
(FR) TRAITEMENT DE L'AIR DANS UN MOTEUR À PISTONS OPPOSÉS TRÈS RÉSISTANT
Abstract
(EN) An air handling arrangement in a two-stroke cycle, opposed-piston engine with unif!ow scavenging and constructed for heavy-duty operation includes sequentially arranged turbochargers in series with a supercharger, in some aspects, the air handling system is equipped with an EGR channel.
(FR) La présente invention concerne un système de traitement de l'air dans un moteur à deux temps, à pistons opposés avec balayage Uniflow, conçu pour les opérations lourdes, ledit système comprenant des turbocompresseurs disposés séquentiellement en série avec un surcompresseur. Dans certains aspects de l'invention, le système de traitement d'air est équipé d'un conduit RGE.
