Cummins won’t let diesel die: New emission lowering tech throws fuel a lifeline, for now

This article was originally published by Michael Coates onClean Fleet Report, a publication that gives its readers the information they need to move to cars and trucks with best fuel economy, including electric cars, fuel cells, plug-in hybrids, hybrids and advanced diesel and gasoline engines.

According to dozens of automotive story headlines, the internal combustion engine, running on gasoline or diesel, is dead or dying as customers, auto companies, and investors flock to electric powertrains. Even heavy-duty trucks running on massive diesel engines, which were expected to be the last on-road holdouts, have been mandated to turn completely to zero emissions in by the state of California starting in 2045.

While 2045 may still be more than two decades away, emissions advances in internal combustion engines (ICE) are continuing. A new technology may take the already quite clean (especially compared with engines of just a little more than a decade ago) engines to a level that reduces smog-producing emissions while increasing fuel economy and yet not losing any performance. The technology study was announced last month by Cummins, the largest heavy-duty engine manufacturer, and Tula Technology, a technology innovator in Silicon Valley that has become a supplier to OEMs.
