TOYOTA EMISSION CONTROL SYSTEMS FOR JAPANESE EMISSION STANDARDS

This paper outlines the three emission control systems employed by Toyota to meet Japanese emission standards. The first system known as the three-way catalyst system, is described as having the highest potential in terms of NOx control, fuel economy and engine power, and is applied to the heavier inertia-weight class models. The second system called the turbulence generating pot (tgp) with oxidation catalyst system, is applied to the middle-inertia-weight class cars. The oxidation catalyst system adopted for lower-inertia-weight class models completes the list. The paper concludes with a brief review of a number of other emission control devices: exhaust gas recirculation (egr), secondary air supply and auxiliary air-fuel ratio control. (Author/TRRL)
