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. Catalysts Emissions Engines
