Inventor: SANO KAZUYOSHI
IPC: F02M31/12
Filed: 1985-09-26
Abstract: PURPOSE:To prevent icing of carburetor without sacrifice of engine output by projecting a planar heater in the upstream of a throttle valve while traversing an intake path and directing the sideface in the direction of gas flow. CONSTITUTION:In a carburetor 8, a heater 32 for heating the intake air is arranged in the upstream of a throttle valve 16 and screwed over an intake barrel from the outside to traverse an intake path 9 thus to reach the tip near to the wall of the intake path at the other side. Upon power supply to the heater 32, the intake air flowing near the heater is heated to transmit the heat to the throttle valve 16 or a needle valve 18 thus to maintain at relatively high temperature, thereby icing of moisture contained in the intake air in the fitting gap between the throttle valve 16 and a guide tube 12 or between the needle valve 18 and a fuel injection port 20 can be prevented. Since the heater 32 is planar and projected while directing the sideface in the direction of gas flow, contacting time with the intake air flow is lengthened while the intake air resistance is minimized.
