Missed their targets? Some clarfication on this might be required (A goal or minimum of 8% yet only achieved 2.7% on post EGR engines)...I might be mistaken but it appears they missed their target by 70%? Any clarification would be appreciated
"The objective of this dynamometer testing was to simulate real-life environments with high accuracy and repeatable conditions on an in-service Class 8 truck to determine how much H2/O2 was required for a minimum of 8%"
"While altering flow of gases, and depending on different settings of H2/O2, test results verified a range of fuel consumption reductions from 2.7% to 19.2% equally on post EGR and pre-EGR engines."
