DEVICE FOR ENHANCING CARBURATION IN GASOLINE ENGINE Russian patent published in 2000 - IPC

FIELD: engine manufacture. SUBSTANCE: device includes electrically-heated element made from posistor ceramic and secured under throttle valve of carburetor mixing tube through plastic gasket fitted carburetor and engine intake pipe line, as well as electric contacts for connecting the electrically-heated heated element to automobile supply line. Specific feature of device consists in form of electrically-heated element which includes several electrically interconnected rectangular plates mounted in succession in inclined position at spaced relation between planes in holes of plastic gasket under carburetor; larger axes of plates are parallel relative to axis of carburetor throttle valve. After starting the engine in the warming-up mode, fuel-and-air mixture fed through primary chamber of carburetor which contains particles of liquid fuel gets on heated plates where liquid phase of fuel evaporates intensively, thus enhancing homogeneity of fuel-and-air mixture and consequently facilitating start of engine and its warming-up at reduced consumption of fuel and toxicity of exhaust gases. EFFECT: reduced toxicity of exhaust gases; enhanced economical efficiency; facilitated start and warming-up; compactness; low aerodynamic resistance and high efficiency. 2 dwg
