ABSTRACT:
A control for carburetor-supplied induction systems for internal combustion engines. The engine includes a carburetor and a principal induction passage leading to an intake valve and thence to a combustion chamber. A principal throttle in the carburetor controls the supply of air/fuel mixture to the principal induction passage as a function of throttle setting and engine demand. This invention includes an auxiliary throttle valve in the principal induction passage between the principal throttle and the intake valve, and an auxiliary induction passage extending from a point in the principal induction passage between the two throttles to a point adjacent to the intake valve where its discharge will, when the intake valve is open, enter the combustion chamber in such a way as to cause swirl and/or turbulence. The auxiliary throttle is closed at light loads so that the bulk of the intake charge is delivered to the combustion chamber through the auxiliary induction passage. The invention contemplates the use of one carburetor for more than one cylinder, and also a number of carburetors equal in number to the number of the cylinders.
