摘要： An intermittent fuel-injection method for two-stroke engine, which is done by means of an injection nozzle mounted under a cylinder head or on cylinder wall so as to have fuel directly injected into a cylinder to mix the air inside the cylinder into a homogeneous mixture; a controller is used for controlling the fuel-injection timing and quantity; the controller determines the injection timing and quantity in accordance with the engine intake air flow quantity and engine rpm; under idle running or low-load running condition, an intermittent fuel-injection control method is used so as to enable an engine to perform one, two, three, four or five scavenging and exhaust cycles after one fuel-injection cycle in order to obtain a steady and high combustion efficiency.
