| Abstract(E) | The Diesel powerplant in heavy applications characterizes all over the world the backbone of goods transport. Driven by a variety of objectives, fuel efficiency has always displayed an engineering goal and will continue in the mid-term horizon. This paper reviews an innovative study based on an in-series engine definition in the 2 l/cyl class. The most important aspects include design elements as uplifted combustion pressure with higher compression ratios and innovative bowl geometries, supported by upgradations on fuel and air delivery side, but include also novel S/B ratios and adjusted stroke characteristics, plus thermal coating for reduction of heat losses |
