摘要
Abstract
A strategy for controlling NOx、CO and HC emissions from an automotive gasoline engine was proposed. NOx emission was decreased by exhaust gas recirculation(EGR) and a set of EGR system, which could give the optimizing EGR characteristics needed by engine emission test cycle was developed.The structure and constitution of these EGR system were also introduced.The fuel economy penalty at low load conditions caused by EGR was alleviated by a little advance of ignition.CO emission was controlled by strict adjustment of air-fuel ratio.HC emission at high speed idling was eliminated by a corresponding fuel cut-off device.This strategy as well as its validity were proved by the engine tests.关键词
