TWO-STROKE ENGINE OPERATION METHOD AND INTERNAL COMBUSTION TWO-STROKE ENGINE

摘要

The present invention relates to the operation processes of two-stroke engines. A two-stroke engine uses a slide valve (10) so that the inlet-outlet channel (9) connected to the exhaust manifold (18) may be connected to the inlet pipe after the outlet of exhaust gases from the cylinder (4). A fresh load is then introduced into the cylinder (4) simultaneously through a bleed window (6) connected to the crankshaft housing (2) by a bleed channel, and through an inlet-outlet window (8) connected to the inlet pipe. The crankshaft housing (2) is filled when the piston (5) moves from the bottom dead centre after the window (8) is opened at its lower edge. Practically continuous feeding of fresh loads into a single-cylinder engine can thus be achieved. The increase in the time-section ratio of the gas distribution organs ensures maximum filling of the cylinder (4) while reducing the time therefor and the losses to a minimum. The heat, which is emitted at the surface of the hottest parts after the outlet, is instantaneously eliminated by the cold fresh loads passing therethrough.
