Abstract
A two-stroke engine having an intake valve and an exhaust valve arranged on an inner wall of the cylinder head, an intake passage connected to the cylinder via the intake valve, a fuel injection device arranged in the cylinder, for injecting fuel into the cylinder, a pressure regulator for regulating a fuel pressure supplied to the fuel injection device on the basis of a scavenging pressure in the intake passage, to thereby increase the fuel pressure in accordance with an increase of the scavenging pressure, and a control device for controlling the injection of fuel by the fuel injection device for a time ranging from a time at which the intake valve is opened to a time at which the scavenging pressure becomes equal to a pressure in the cylinder after the intake valve is closed.
