Fluid extraction arrangement for engine air induction system

USPTO Application #: 20070261394
Title: Fluid extraction arrangement for engine air induction system
Abstract: An engine includes an air induction system for providing air to a plurality of cylinders, an exhaust system for conveying exhaust gas from the cylinders, and a secondary air injection (SAI) system for extracting air from the induction system and injecting the air into the exhaust system to promote exhaust gas oxidation and to heat a catalytic converter. The SAI system extracts air from the induction system through a plurality of holes to evenly distribute the effects of the extraction, thereby reducing velocity gradients and turbulence levels around the mass air flow sensor inside the induction system. (end of abstract)
