INTERNAL COMBUSTION ENGINE FUEL HEAT TREATMENT DEVICE Russian patent published in 2001 - IPC

FIELD: mechanical engineering; internal combustion engines. SUBSTANCE: invention relates to fuel system of carburetor engines. Proposed device has carburetor 1 connected by outlet channels with inlet of intake pipe 2 and connected by pipe 3 through pump 4 to fuel tank 5. It has also fuel evaporator and exhaust gas outlet pipe 7. Fuel evaporator is made in form sprayer of hot exhaust gases installed at outlet of carburetor 1. Nozzle 10 of sprayer are pointed to flow of drop - air fuel mixture for treatment of cross layer. Hot exhaust gas sprayer is connected with space of exhaust gas pipe 7 by pipe 8. Exhaust gas cleaning filter 9 is installed in cut. Hot exhaust gases from space of pipe 7 are cleaned from suspended particles in filter 9 and are sprayed into flow of drop-air fuel mixture through nozzles 10 of sprayer 6. Fuel trap can be installed at inlet of intake pipe for evaporation of remaining heavy drop-like fractions of fuel. This trap is heated by hot exhaust gases from sprayer 6. EFFECT: conversion of drop-air fuel mixture formed in carburetor 1 into guilty gaseous fuel mixture at inlet of intake pipe 2. 9 cl, 3 dwg
