The spark-ignited gasoline engine is still the most common internal combustion engine (ICE) built into passenger cars and light duty vehicles (LDV). Globally, more than 70 million vehicles are presently equipped with gasoline engines increasing to >80 million vehicles beyond 2021.
Introducing the three-way catalyst (TWC) in the late 1980s and early 1990s, emissions from gasoline engines have already been reduced significantly. Fuel-saving engine technologies – like the gasoline direct injection (GDI) engine – have been established broadly in the market with further growing emphasis on global warming and greenhouse gas emissions. These more efficient GDI engines and their different combustion modes (lean burn, stoichiometric and full power output) require highly advanced aftertreatment solutions, especially NOx and particle emissions.
Umicore provides technical solutions supporting car manufacturers (OEM) worldwide fulfilling ever-tightening global emission standards. Our portfolio for gasoline applications includes three-way catalysts (TWC), NOx storage catalysts (NSC) as well as catalyzed gasoline particulate filters (cGPF).
