Over the years, multiple engine manufacturers have offered mechanical turbo compounding on some engine models as a means to improve the efficiency of diesel engines. In theory, converting exhaust energy which would otherwise be wasted to shaft work seems like a technical path that no manufacturer should ignore especially in today's world with the uncertainty of future CO₂ emission regulations or fuel economy standards. This paper offers an independent examination of the effectiveness of the most recent implementation of mechanical turbo compounding on the Detroit Diesel (Daimler) DD15.
