Summary:

Future vehicles will increasingly be required to improve theirefficiency, reduce both regulated and CO₂ emissions, and maintainacceptable levels of driving, safety, and noise performance. Toachieve this high level of performance, they will be configuredwith more advanced hardware, sensors, and control technologies thatwill also enable their operation on a broader range of fuelproperties. These capabilities offer the potential to design futurevehicles to operate on the most widely available and GHG-reducingfuels.In previous studies, fuel flexibility has been demonstrated on acompression ignition bench engine and vehicle equipped with anadvanced engine management system, closed-loop combustion control,and air-path control strategies. An unresolved question is whetherengines of this sort can operate routinely on market gasoline whileachieving diesel-like efficiency and acceptable emissions and noiselevels.This paper describes initial engineering and experimental stepsto assess this potential. Using an advanced diesel bench enginehaving a higher compression ratio, optimized valve timing, andflexible fuel injection, the engine could be operated on a Europeanmarket gasoline over full to medium part loads. The combustion wasfound to be highly sensitive to EGR rates, however, and thesimultaneous optimization of all regulated emissions and combustionnoise was a considerable challenge. An advanced glow plug wastested to improve low load performance but did not extend theengine operating range as much as expected
