Multi-fuel operation of modern engines; On board fuel identification

MULTI-FUEL OPERATION OF MODERN ENGINES; ON BOARD FUEL IDENTIFICATION by FLORIN MOCANU August 2012 Advisor: Dr. Dinu Taraza Major: Mechanical Engineering Degree: Doctor of Philosophy Modern engines require enhancement of electronic controls to achieve better fuel economy, high power density and satisfactory emissions levels while operating safely. Commercial and military vehicles should run safely and efficiently on any fuel available on the market or on the battlefield, therefore on-board fuel identification and adaptation of engine controls to the type of fuel becomes extremely important. The use of an inexpensive, nonintrusive sensor is highly desirable. The development of a technique based on the measurement of the instantaneous crankshaft speed and engine dynamics could be a convenient solution. Several such methods have been elaborated at the Center for Automotive Research in the Mechanical Engineering Department at Wayne State University, each of them yielding plausible results regarding on-board fuel identification.
