Method and apparatus for preparation and control of air-fuel mixture to the air intake of an engine

摘要

A method and apparatus for the preparation and control of an air-fuel mixture to the air intake of an engine in which the fuel is continuously delivered to a multi-stage atomizer by a gas at a pressure higher than the ambient pressure, the pressure of the gas being controlled in accordance with the engine speed and load. The fuel is continuously atomized and homogenized, preferably several times, in the atomizer. The atomizer is installed in the engine air intake ahead of the throttle and the fuel is atomized by the gas delivered through a passage, and the mixture thus prepared is introduced into the air intake above the throttle where it is mixed with the air induced by the engine to charge the engine cylinders.
