Abstract Details

2011, Master of Science, Ohio State University, Mechanical Engineering.
The EcoCAR challenge is a three year competition with the goal of re-engineering a 2009 General Motors crossover utility vehicle to improve vehicle emissions and fuel economy, while maintaining drivability and consumer acceptability. Ohio State’s team has selected an extended range electric vehicle (EREV) architecture with a 1.8 L compressed natural gas (CNG) Honda engine as the auxiliary power unit. This engine was chosen because of its 12.5:1 compression ratio, which results in higher brake efficiencies than a traditional spark-ignition (SI) engine. The Honda engine is converted to run on E85 fuel, which requires the engine control software to be rewritten. The purpose of this project is to improve the engine control strategy to reduce tail-pipe emissions and increase fuel economy. This research investigates a model-based calibration methodology to develop accurate engine calibrations for several operating parameters. The methodology utilizes design of experiments (DoE) techniques for data collection and advanced data analysis tools in MATLAB to develop accurate and robust engine control calibrations. The control software developed by Ohio State to run the Honda engine on E85 fuel resulted in a peak engine brake efficiency of 41% and a vehicle that meets EPA Tier II Bin 3 emissions standards.
