Mechanical discharge self-supercharging engine

Abstract

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.
