A Fuel Control Strategy that Optimizes the Efficiency of a Direct-Methanol Fuel Cell in an Automotive Application
For automotive applications, it is necessary to maximize the fuel conversion efficiency of a PEM direct-methanol fuel cell (DMFC) over the broadest possible dynamic range of power. The research reported here critically examines the efficiency of the DMFC stack when operated over a broad power range. This research establishes a basis for a control strategy that simultaneously: optimizes DMFC fue...
متن کاملEffect of Automotive Electrical System Changes on Fuel Consumption Using an Incremental Efficiency Methodology
There has been a continuous increase in automotive electric power usage. Future projections show no sign of it decreasing. Therefore, the automotive industry has a need to either improve the current 12 Volt automotive electrical system or move to a higher voltage vehicle electric system. Both of these choices are likely to increase cost of the system. Performance improvements will be needed to ...
متن کاملAutomotive Engineering: Engine Fuel Map Design
In order to understand how to bring out the most power from a car’s engine, we needed to learn how an engine works. The main focus of this research was to tune the engine and create a fuel map that would allow it to run at its optimum level. We used the Win Tec-GT computer software to test the performance of a 2002 Yamaha YZFR6 engine that the Rutgers 2008 Racing Team uses in their car. To easi...
متن کاملTowards Egocentric Fuel Efficiency Feedback
Motivated by anecdotal evidence, we hypothesize that an egocentric approach is more appropriate and relevant to providing fuel efficiency feedback than a systemic approach. In this paper we describe a proposed study to test this hypothesis, and present the design of a fuel efficiency feedback system for public transit bus drivers.
متن کاملComparison of Hybrid Fuel Cell Vehicle Technology and Fuel Efficiency
Hybridization of fuel cells with additional batteries or ultracapacitors in a fuel cell vehicle reduces electrical and mechanical stresses on fuel cells and improves the overall drive train efficiency over a standard drive cycle. This paper primarily analyzes hybrid fuel cell vehicles with different drive train arrangements, and compares projected fuel economies of hybrid fuel cell vehicles wit...
