Low temperature starting on a pure ethanol fuelled direct injection engine

In the current study cold start tests have beenperformed on a multi-cylinder, spray guided directinjection, spark ignition engine. The direct injection systemwas a centrally mounted dual fluid type injecting fuel andair simultaneously. The engine has been started on ethanolat soaked temperatures from +25?C through to -10?C.Development of engine hardware, software and calibrationwas undertaken to optimise cold start times, whilst qualitymetrics were used to evaluate the performance of the starts.Consideration has been taken to restrict hardware options toproduction viable components. Conclusions are drawn regarding the start performance of an E100 spray guide DIengine at low temperatures.</p
