Title: Instantaneous and cycle optimization of fuel usage on a dual fuel vehicle leveraging gasoline and natural gas

Abstract

Recent increases in natural gas supply have led to a desire to leverage this fuel in the transportation sector. Dual fuel engines provide a platform on which to use natural gas efficiently; these engines, however, require new hardware and new control strategies to properly utilize two fuels simultaneously. This paper explores the impact of implementing dual fuel capabilities on a sedan and demonstrates that a dual fuel E10 and compressed natural gas engine is able to improve the average engine efficiency by up to 6.5% compared to a single fuel engine on standard drive cycles. An optimal control technique is also developed, and the proposed approach allows factors including fuel cost and fuel availability to be taken into account. Optimization at each time instant is investigated and contrasted with optimization over the entire cycle. Cycle optimization is shown to have particular value for cases in which the level in one fuel tank is low.
