Title: Turbocharger control system

Abstract

A turbocharger control system is described utilizing a carburetor system. This system includes a carburetor having an air-fuel induction passage, a fuel supply passage for supplying fuel to the air-fuel induction passage, and a turbocharger compressor impeller disposed upstream of a throttle valve and compressing an air-fuel mixture flow delivered to an engine intake manifold. The turbocharger control system comprises: a surge tank provided in the intake manifold; an air control valve including means for controlling an air bleeding amount supplied to the air induction passage in response to changes in pressure of the surge tank. The air control valve further comprises a valve housing having an end wall and including a first, second and third chamber formed therein. A diaphragm has a valve member for controlling communication between the second chamber and the third chamber in response to a pressure existing in the first chamber, a spring biasing the diaphragm in a direction such that the valve member is maintained in a closed position against the pressure in the first chamber. A valve seat plate is in contact with the valve member. The first chamber is connected with the surge tank and the second chamber is connected with themore » fuel supply passage, and the third chamber is connected with atmosphere. The first chamber is defined by a valve housing of the air control valve, the end wall and the diaphragm and the valve member has a tapered form.« less
