	Air flow based MBC for torque control during lean-rich switching

	Tail pipe NOx reduction with low temperature combustion

The Clean Diesel Consortium is managed by Southwest Research Institute (SwRI) and has been operating since 1991. The current program is called Clean Diesel V.

Clean Diesel III (1999–2003) initially focused on the development of diesel aftertreatment systems.

Highlights and Outcomes:

Demonstrated US 2010 compliant emissions levels using MBC+LNT+cDPF system in 2003
Approached low operating temperature emissions control using advanced low-temperature combustion technology, incorporating VVA (variable valve actuation) technology
Developed full operating range HCCI, including fuel effects.

A brochure highlighting the Clean Diesel Program is available.
