High-Throughput Screening Technology for Automotive Applications

The development of advanced emission control systems to meet the strict regulations requires efficient and flexible material screening capabilities. Here, a high throughput test unit is described. Two case studies demonstrate the rapid screening of relevant parameter spaces and material functionalities which can be used in product development. One involves steady‐state testing of hydrocarbon oxidation in Diesel aftertreatment systems, while the other shows the evaluation of oxygen storage capacity in the optimization of three‐way catalysts for gasoline engines. Hydrocarbon oxidation is an important functionality of exhaust gas purification systems. In the development of such systems, material screening for the evaluation of heterogeneous catalysts is an essential part. Here, a high throughput screening method is developed, offering a correlation between catalyst composition and performance.
