Title:
SLIDING VALVE TYPE CARBURETOR
Document Type and Number:
Japanese Patent JPH07279768
Kind Code:
A
Abstract:

PURPOSE: To raise degree of freedom for controlling fuel supply rate to an intake passage and provide optimum air-fuel ratio control in response to the operating condition of an engine.

CONSTITUTION: Fuel stored in a float chamber 15 is supplied to an intake passage 12 through a needle jet 17. Air is supplied from a solenoid valve 26 to the needle jet 17 through an air passage 24. Thus the negative pressure in the needle jet 17 varies and the amount of fuel supplied to the intake passage is brought under control. Opening and closing of the solenoid valve 26 is controlled in response to the operating condition of an engine. Therefore air-fuel ratio can be controlled independently of the opening and closing of the sliding valve 12 and can be varied, for example, in response to the engine speed.
