According to a study conducted for the North American Heavy Duty SCR Stakeholders Group and FactsAboutSCR.com, 53.4% of small and large fleet managers, owner-operators and maintenance managers surveyed said they would likely consider SCR (selective catalytic reduction) for their next truck purchase compared to 29.4% that would consider EGR (exhaust gas recirculation).
When each emissions technology was briefly described, 33.7% of respondents said they would only consider the purchase of SCR trucks compared to 10.2% who said they would only consider trucks with EGR, according to the group.
However, nearly half of the respondents said that they do not yet know which emissions technology will deliver key benefits including fuel savings and fewer active regenerations, according to FactsAboutSCR.com.
All U.S. engine suppliers except for Navistar plan on using SCR to meet Environmental Protection Agency (EPA) 2010 standards. Navistar has not yet responded to an inquiry for a response to this study.
The North American SCR Stakeholders Group is a collection of public and private organizations that seeks to create awareness for SCR as what it terms the most fuel-efficient and effective emissions technology available. The study was conducted for them by Quixote Group Research.
