DEVICE FOR IMPROVING FUEL-AIR MIXING IN CENTRAL INJECTION SYSTEM Russian patent published in 2002 - IPC

FIELD: mechanical engineering; fuel devices of internal combustion engines. SUBSTANCE: proposed device has electrically heated element made of posistor ceramics arranged under throttle valve of fuel feed unit mixing chamber. Fuel feed unit is provided with idle air bypass channel installed on plastic gasket placed between fuel feed unit and engine intake pipe. Bypass channel has electric contacts for connection to automobile electric circuit. Electrically heated element is made in form of rectangular plate installed at angle under lower edge of throttle valve near outlet section of idle bypass channel. Plate longitudinal axis is parallel to axis of throttle valve and is arranged in plan along chord relative to circumference of mixing chamber channel. EFFECT: reduced fuel consumption and toxicity, facilitated and accelerated starting and warming of gasoline engines with central fuel injection system. 2 dwg
