ABSTRACT:
A turbocharger having a by-pass system for selectively by-passing exhaust gases from the turbine rotor. The by-pass arrangement includes a housing portion having a by-pass passage which preferably extends from the exhaust inlet to the exhaust outlet. There is a port from the exhaust inlet into the by-pass passage which is selectively controlled by a pivoted valve. The turbocharger with the by-pass arrangement may be utilized with a conventional vehicle exhaust system of the type having a catalytic convertor and if so desired, a major portion of the by-pass gases may also by-pass the catalytic convertor. A control device disposed remote from the turbocharger permits the use of relatively inexpensive control elements.
