FUEL SAVING DEVICE OF INTERNAL COMBUSTION ENGINE

摘要

PURPOSE:To readily obtain an optimum quantity of air and addition liquid of liquid fuel such as kerosine, light oil or the like in a device described in the heating which adds the liquid fuel to main fuel mixture such as IP gas or so and burns them. CONSTITUTION:An addition liquid reservoir 1 is a closed reservoir having an opening 10 in the upper position and containing addition liquid 30 in the lower space thereof. An addition liquid outlet passage 3 runs between a float chamber and a flow rate control valve 7 and an air outlet passage 4 runs between the flow rate control valve 7 and an air filter 2. The air outlet passage 4 and the addition liquid reservoir 1 are connected to each other by a differential pressure pipe 11 and a differential pressure supply passage 12 which extends from the differential pressure pipe 11. The air outlet passage 4 has the first orifice 17 at the position more upstream than the point at which the passage 14 is communicated with the differential pressure supply passage 12, which has the second orifice 18. The first orifice 17 has a diameter which is as large as addition liquid may be properly sprayed and is smaller than that of the second orifice 18.
