Abstract
An experimental investigation, using a Design of Experiments approach, has sought to quantify the potential CO2 savings that could be made by the electrification of certain mechanical devices as part of the Front End Auxiliary Drive (FEAD) on a 2.4 litre DI diesel engine. The experiments considered the electrification of the cooling fan; power assisted steering system, and the vacuum pump. A number of different build configurations have been evaluated on a dynamic testbed over the New European Drive Cycle (NEDC). The overall conclusion is that the move towards electrification of the devices listed would result in a 6-7% saving in CO2 over the NEDC. These benefits however, need to be considered alongside other issues such as increased on-cost, more control complexity and reliability implications of adopting electrically driven devices.
