Abstract
(EN) When considering the main types of commercial engines available on the market, whether two-stroke, four-stroke or rotary-type, it is found that, and this is commonplace, said engines are highly polluting. The main reason for this lies in the difficulty to manufacture worn gas filters which would not induce restriction. However, that difficulty can be overcome by producing an engine which is itself capable of sustaining a high rate of restriction. The technical solutions disclosed by the invention present several embodiments enabling the engine to tolerate a higher level of restriction and consequently a more dense filtering. These various technical embodiments provide for a novel path for fresh gases through the engine. The invention provides a solution, which is not primarily concerned with fresh gas supply but rather with waste gas absorption, followed by their subsequent evacuation constituting the first stroke of said engine. Indeed, the waste gases are evacuated outwards by two successive steps: the gases are evacuated outwards by pumping, and said discharge generates, in turn, a vacuum which sucks in the burnt fresh gases which in turn finally suck in the fresh gases. Said techniques have the further advantage of producing two stroke engines powered with gas only, and consequently cleaner and more efficient.
(FR) Lorsque l'on regarde les principaux types de moteurs commerciaux sur le marché, qu'ils soient à deux temps, à quatre temps ou encore de type rotatif, l'on constate que, et c'est là un lieu commun, ces moteurs sont très polluants. La raison principale de cet état de fait réside dans la difficulté de construire des filtres des gaz usés qui n'offriraient pas de restriction. Cette difficulté peut cependant être surmontée en produisant un moteur lui-même capable de supporter un haut niveau de restriction. La présente solution technique présente donc plusieurs réalisations permettant au moteur d'accepter un haut taux de restriction et par conséquent une filtration plus dense. Ces diverses réalisations techniques établissent de façon nouvelle le parcours des gaz à travers le moteur. Dans la présente solution ce n'est pas d'abord l'alimentation en gaz neufs qui est visée, mais plutôt l'absorption des gaz usés, puis leur évacuation qui constituent le premier temps de ce moteur. En effet, les gaz usés sont d'abord évacués vers l'extérieur, à travers deux étapes successives. En effet, les gaz sont évacués vers l'extérieur de façon pompée, et cetteévacuation crée, à son tour un vide qui succionne de nouveaux gaz brûlés qui à leur tour aspirent finalement des gaz neufs. Ces techniques ont aussi l'avantage de produire des moteurs deux temps mus seulement au gaz, et par conséquent plus propres et plus efficaces.
