Researching Diesel Engine Retrofits and Learning From the Research Process

摘要

When I received the project's background information, my first instinct was to run screaming, a la Butterfly McQueen's character Prissy in the movie Gone With the Wind, "I don't know nothin' 'bout diesel engine retrofits!" The manufacturer was a leader in the on-road market for retrofits, but the off-road market was emerging as a new priority, driven by California Environmental Protection Agency Air Resources Board's (CARB) anticipated passage of a rule to reduce diesel particulate matter (PM) and oxides of nitrogen (NO_x) emissions from existing off-road heavy-duty diesel vehicles. This mouthful of words required several readings before I could fully digest them.
