Abstract
An electrically heated catalyst (EHC) and an electric pump driven secondary air supply were employed to heat and energize the catalyst immediately after starting the engine. This measure made it possible for a high performance in-line four-cylinder engine with an exhaust system layout of 4-2-1 to meet the Ultra Low Emissions Vehicle (ULEV) category of the Californian Air Resource Board (CARB).
