Abstract

We have succeeded in developing a test system (DELTA100, DAIHATSU Emission Laboratory

Testing Apparatus 100) for creating exhaust emission control systems needed in response to current and future environmental problems. This system combines a simulation of vehicle driving performance, along with a packaging test utilizing a transient dynamometer, and multiple exhaust gas analyzers. In this paper we provide an overview of this system and an example of its application in catalyst design.

By implementing our system, various types of catalysts can be developed utilizing different gases and engine control logic can be evaluated on an engine bench without having to construct an actual test vehicle. Consequently, development of control and catalyst systems is easier and design of vehicle layout and sophisticated catalysts is greatly simplified.
