TWO-STROKE INTERNAL COMBUSTION ENGINE

摘要

A two-stroke internal combustion engine comprising a combustion space, which is enclosed by a cylinder having an end wall, and a piston that is connected to a crankshaft, which piston is capable of reciprocating motion within the cylinder between a position in which the combustion space has a minimum volume and a position in which the combustion space has a maximum volume, wherein a first valve is capable of closing an inlet opening in the end wall and a second valve is capable of closing an outlet opening in the end wall, which outlet opening is at least substantially closed at the moment when, at least substantially not before said moment, and the inlet opening is open at the moment when the piston is in the position in which the combustion space has its minimum volume, and wherein the minimum volume of the combustion space in cold condition amounts to less than 3% of the maximum volume of the combustion space.
