Title:
CARBURETOR POWER FUEL CONTROLLER
Document Type and Number:
Japanese Patent JP3472895
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide optimal power fuel for holding an engine output to a high level when the revolution number of the engine exceeds a fixed high revolution number.
SOLUTION: A power fuel control jet 14 facing an upstream side and an always opened type solenoid valve NO for closing a power fuel passage 20 only when the revolution number of an engine exceeds a fixed high revolution number are arranged in series in a power fuel passage located more upstream than a power nozzle 13. A downstream side power fuel passage 20A between the solenoid valve NO and the power fuel control jet 14 and an upstream side power fuel passage 20B which is located on the upstream side of the solenoid valve NO are connected to each other by a bypass power fuel passage 22. A sub power fuel control jet 23 having a diameter smaller than the jet diameter of the power fuel control jet 14 is arranged inside the bypass power fuel passage 22.
