Latest bioMSAR testing at Aquafuel Research confirm efficiencies and emissions reductions

In the UK, Quadrise confirmed the results of the latest bioMSAR testing at Aquafuel Research Ltd’s UK test facility.

The results relate to further engine optimization testing of bioMSAR, conducted on the company’s Cummins high-speed 4-stroke diesel engine generating set, to allow accurate performance monitoring, optimization and measurements to be made. They follow the initial testing at Aquafuel, the results of which were published by the company on February 1, 2021.

During 2021 the engine was modified to allow injection timing to be advanced and performance to be monitored more accurately. These enhancements provided the ability to assess and optimize engine efficiency and emissions whilst using bioMSAR™ and other fuels.

Initial baseline runs under the latest testing were undertaken to ensure prior bioMSAR performance results were repeatable. These confirmed previously announced engine efficiency benefits of 3% and reductions of Nitrogen Oxide (“NOx”) emissions of over 20% in comparison to diesel fuel.

The next phase of testing now completed has demonstrated that by advancing injection timing, engine efficiency can be increased by over 13%, thereby further reducing fuel consumption and carbon dioxide (“CO2”) emissions.

Ordinarily, higher engine efficiencies result in increased combustion temperatures and NOx emissions. However, of particular note, the latest tests at Aquafuel have confirmed that it was possible with bioMSAR™ to reduce the inlet air temperature to the same level as diesel. This resulted in NOx levels being further reduced by over 30%, some 45% lower than diesel fuel.

These latest tests have therefore shown that much higher diesel engine efficiency can be achieved with bioMSAR, without increasing NOx emissions.  Further tests are being planned with Aquafuel during the year to focus on fully defining efficiency and emissions optimization settings.
