What is SI Engine Emission Control Overview about?
This document discusses thermal catalytic deactivation and summarizes emission control technologies for spark ignition engines. It describes how high exhaust temperatures can damage catalytic converters by sintering the precious metal catalyst particles and changing the substrate material. Technologies introduced over time to control emissions include positive crankcase ventilation, catalytic converters, fuel injection, onboard diagnostics, and new catalyst formulations. The maximum operating temperature of
