Today’s powerful and efficient gasoline direct injection (GDI) engines are giving drivers around the world the fuel efficiency and engine performance they crave.
But GDI engines can also bring a dangerous side effect: microscopic particles of airborne carbon and other harmful chemicals, called PM2.5, the term for particulates measuring less than 2.5 microns across. Some are so small, you could fit thousands on the head of a pin. When inhaled, the invisible particulate matter can migrate from the lungs into the bloodstream, potentially leading to pulmonary and cardiovascular problems as well as other health issues.
To help address the growing problem in regions across the world, governments and the auto industry are making regulatory changes and technical engineering advancements. Many countries are dramatically restricting the amount of particulate matter that auto engines may release into the air. Carmakers are facing stringent new limitations in Europe with even tighter regulations begin in China in 2023.
The technical challenge is complex. An emissions control system that greatly reduces fine particulates must work under all manner of demanding driving conditions, from short runs in the city to long-haul drives on the highway. It must also be cost-effective and not compromise fuel efficiency or engine back pressure which drives engine performance.
