| 摘要： | 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. |
