Abstract
This paper presents experimental results of a 10.6L, three-cylinder opposed-piston (OP) operating on diesel fuel designed for heavy duty (Class 8) operation. The paper will describe the engine configuration and calibration of both catalyst light-off and high efficiency modes.
Analysis based on measured results show the engine can comply with all 2027 California Air Resourced Board (CARB) and Environmental Protection Agency (EPA) requirements for CO2 and criteria emissions. Due to the ability of the OP Engine to combine low oxides of nitrogen (NOX) flux with high exhaust enthalpy for early catalyst light off, the engine can meet all 2027 CARB and EPA NOX standards with a current, state of the art conventional underfloor aftertreatment system. No additional emissions control technology is required.
