Abstract

A series of NEDC tests have been conducted to compare the relative performance of two designs of variable flow oil pump (VFOP) to the production oil pump on a modern HSDI Diesel engine. The first design offered a 3.4% saving in fuel consumption over a cold NEDC. The second design offered a 2.6% reduction. Transient tests showed that the second design exhibited better control to the desired 3bar pressure limit although both pumps demonstrated much improved gallery pressure control compared with the production system. The potential impact is considerable as the conventional IC engine is likely to be an important prime mover for decades to come, in both conventional and hybridised powertrains, and as such the improvement in vehicle pare fuel consumption that could be achieved by the widespread adoption of such technologies is a key aspect of meeting future CO2 targets.
