Experimental Dataset: Optimal control of an over-actuated spark-ignited hydrogen engine

The spark-ignited (SI) hydrogen combustion engine has the potential to noticeablyreduce greenhouse gas emissions from passenger cars. To prevent nitrogen oxideemissions and to increase fuel efficiency and power output, complex air paths andoperating strategies are utilized. This makes the engine control problem more complex,challenging the conventional engine calibration process.This work combines and extends the state-of-the-art in real-time combustion enginemodeling and optimal control, presenting a novel control concept for the efficientoperation of a hydrogen combustion engine. The extensive experimental validationwith a 1.5-liter three-cylinder hydrogen SI engine and a dynamically operated enginetest bench with emission and in-cylinder pressure measurements provides acomprehensible comparison to conventional engine control.The results demonstrate that the proposed optimal control decreased the load trackingerrors by a factor of up to 2.8 and increased the engine efficiency during lean operationby up to 10 percent while decreasing the calibration effort compared to conventionalengine control.
