Regenerative Heat Retaining Element

RHRE is a re-purposed, liquid-fuel, 2-cycle technology currently operationally deployed in unmanned air vehicles (UAVs). RHRE modifies an engine combustion chamber to improve homogeneity of the combustion process. Our scale-up tests in 8.5-inch bore cylinders reconfirm the following improvements running on Natural Gas: combustion stability (typically 5% to 25%, or better), pollutant emissions (10% to 50% lower), fuel consumption (4% to 28% less) and HP (4% to 10% higher). These trends indicate a fundamentally new 2-stroke combustion process with far-reaching implications for our target gas-pipeline market. Reaction from gas-compression industry experts is encouraging, including engine OEMs. These experts recommend field testing to compare with baseline performance.

Enhanced Radical Ignition

Enhanced Radical Ignition (ERI), involves the generation and control of key chemicals naturally created during combustion, known as Radical Ignition (RI) species, to further enhance combustion stability. Creation, storage and transfer of RI species augments ignition in such a way so as to change initiation of the combustion process from a thermal to a chemical-decomposition reaction. ERI has been demonstrated in complex simulation models and liquid-fueled engine lab tests. We plan to extend this design to large-bore, natural-gas-fueled engines based largely upon simulation. Our current development plan for ERI lags RHRE by approximately 18 months.

New Technology Developments

RCT continues to assess other technologies that will provide improved engine performance by improving the combustion process. We are working with our University partners to prove technologies through simulation and lab testing. RCT plans to open an Internal Combustion Engine test facility for application testing.
