Diesel Emission Reduction By On-Board Fuel Reformulation. Final Report

In this Phase 1 proposal, four tasks were investigated: plasma reforming in the mode of energy neutral reforming, testing in a diesel engine with hydrogen injection (port-injection), analysis of the data, and system analysis. It was demonstrated that it is feasible using a compact microplasmatron fuel converter to obtain near energy neutral reforming. Hydrogen addition was used in a compression ignition engine and a factor of 10 decrease in the particulate size concentration and mass was achieved
