Researchers develop effective exhaust catalyst for lower temperature exhaust

Green Car Congress

To improve fuel efficiency, advanced combustion engines are being designed to minimize the amount of waste heat in the exhaust. As a result, future generations of exhaust after-treatment catalysts must perform at temperatures that are 100 °C lower than current catalysts. The researchers designed a catalyst that could endure engine exhaust temperatures of up to 800 ˚C encountered under high engine loads.

Viable exhaust-driven on-board ethanol reforming for improvements in fuel economy and emissions

Green Car Congress

A team at Monsanto and colleagues at AVL Powertrain have successfully designed and demonstrated an onboard low-temperature ethanol reformer that can be driven by exhaust heat. Many papers have described high-temperature steam reforming of ethanol at around 600 °C but.this temperature is too high to be driven by engine exhaust. Because exhaust-driven reforming uses only waste engine heat, it avoids this efficiency hit, the authors note.
