    摘要: An internal combustion engine comprises a cylinder of stepped configuration having a working portion (21) and a pumping portion (22) and a piston of stepped configuration having a working portion (31) and a pumping portion (32), the working (21, 31) and pumping portions (22, 32) respectively co-operating to define a combustion chamber (35) and a pumping chamber (37) each of which varies in volume upon reciprocation of the piston in the cylinder. Air is admitted to the pumping chamber (37) through a duct (43) from where, on volume reduction thereof, it passes via a plurality of passages (49) and a one-way valve (50) into a transfer chamber (47). On volume expansion of the combustion chamber (35), air in chamber (47) is discharged therefrom via a plurality of passages (55), common discharge port (57) and valve (59) to scavenge the combustion chamber (35) and provide combustion air. The valve (59) may be self-acting or operated by a crankshat controlled push-rod. A delivery pump (63) operated pneumatically under the influence of the pumping chamber (37) to deliver fuel or a combustible mixture to inlet passage (76) is also disclosed.

    摘要: 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.

    摘要: An internal combustion engine has first and second cylinders (12, 14), the first cylinder (12) having a larger swept volume than the second cylinder (14) and the second cylinder being formed in the crown of the first cylinder. First and second pistons (16, 18) are reciprocable respectively in the first and second cylinders (12, 14), the second piston (18) being formed as a protrusion on the crown of the first piston (16). A combustion chamber (20) is formed in the second piston (18) with an air port (44) opening into the first cylinder (12) and a second port (40) opening into the second cylinder (14). A first inlet is provided (25) for supplying air or the like into the first cylinder (12) during an induction stroke of the first piston (16) together with a fuel inlet (36) for supplying fuel to said second cylinder (14). A passage extends between the first and second cylinder to enable transfer of air from said first cylinder (12) to said second cylinder (14) other than through said combustion chamber (20) over a preselected angle of movement of the pistons relative to the cylinders for assisting movement of gases from said second cylinder (14) into said combustion chamber (20). Additional control means for controlling the movement of air is also provided.
