Fuels for advanced combustion engines

01 May 2010

Over the past two decades, air pollutant emissions from motor vehicles have fallen dramatically as a result ofcontinuing improvements in vehicle, engine and aftertreatment technologies aided by the widespread introduction of sulphur-free fuels.While air pollutants are still important, today’s priority is to improve engine efficiency and fuel consumption in order to address new concerns regarding future energy supplies and greenhouse gas emissions. These new targets must be met while further reducing air pollutant emissions. Manufacturers of engines and engine equipment are rapidly responding to meet these new challenges. Fuel manufacturers are also interested in knowing what fuels might enable these engine improvements and are ready to contribute to vehicle studies that help to clarify the performance of future fuel and biofuel blends.
