Carburator for a stratified combustion engine with a prechamber

摘要

A carburetor for a stratified combustion engine with a precombustion chamber comprises a first body having first and second bores for supplying lean mixture into a main combustion chamber of the engine, a second body having a third bore for supplying rich mixture into the precombustion chamber, and an actuator for swinging a throttle valve provided in said third bore in accordance with a function proportional to a negative pressure within said first bore. The carburetor is adapted to allow any desired arrangement of said first body and said second body in spaced relation with each other so as to facilitate the arrangement of various equipments in an engine room as well as the design of the engine.
