Now, MIT engineers are proposing using an ammonia-based selective catalytic reduction (SCR) system that could result in an approximately 95% reduction in NO x emissions in exchange for a ~0.5% —Steven Barrett, professor of aeronautics and astronautics at MIT and corresponding author. increase in block fuel burn.

However, prior to the remarks on climate change and the regulatory response, he spent a few minutes discussing the efforts on urban pollution—e.g., What more is need to end urban pollution, something we’ve been spending over 30 years working on? Cooled exhaust gas recirculation (EGR) under boosted conditions. Tim Johnson.

These systems will also need to deliver very low criteria pollutant levels (e.g., One such potential complementary technology for addressing the knock challenge, Kapp said, is the ethanol boosting system Ford has been exploring with MIT. Various types of lean operation are also being investigated for improved BSFC. —Dan Kapp.
