ABSTRACT:
An auxiliary intake passage system for internal combustion engines having a main carburetor delivering a lean mixture to main combustion chambers through a main intake passage, and an auxiliary carburetor delivering a rich mixture to auxiliary combustion chamber through an auxiliary intake passage. The auxiliary intake passage system is comprised of an induction passage leading from the auxiliary carburetor to an auxiliary intake distribution chamber. A plurality of branch passages extend laterally from said auxiliary intake distribution chamber and lead to the auxiliary combustion chambers. The induction passage comprises a first portion of substantially uniform cross-sectional area connected to a second portion which is tapered and so formed that the internal wall of the tapered section is outside the axial projection of the internal wall of the first portion, thus minimizing resistance to fluid flow and improving fuel distribution and homogenation to each combustion chamber.
