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)
