• Abstract:
  Previous engine testing with Catalytic Plasma Torch (CPT) technology at the University of Idaho has shown promising results in ; the reduction of NOx and CO emissions. Because this technology is not yet well characterized, past research has indicated that ; parametric studies of the CPT design should lead to greater control over the combustion event. This report details the process ; used to design and fabricate a highly adjustable research-grade CPT to be used in a variable compression ratio Cooperative Fuels ; Research (CFR) engine. CPT construction techniques originally developed by SmartPlugs, Inc. were used as a baseline for the ; next generation design and fabrication process outlined in this work. The design was improved by making the prechambers ; interchangeable with the feed-through and catalytic core assembly. The feed-through was simplified by using a compression ; style cap made by Conax® Technologies. Testing with the CFR engine shows that the redesigned CPT can withstand combustion ; pressures and facilitate gas phase ignition as effectively as the SmartPlugs design. With the new design and simplified fabrication ; process, families of CPT assembly combinations can be produced locally and inexpensively. This will allow quick and simple ; adjustment of many physical parameters believed to affect ignition timing and cycle-to-cycle variability.
