Quadrise reports tests results from bioMSAR on 4-stroke engine at VTT facility

September 6, 2021 |

In the UK, Quadrise, the supplier of MSAR and bioMSAR emulsion technology and fuels, reported that test results of bioMSAR on a medium speed 4-stroke Wärtsilä diesel engine at the VTT facility in Finland, confirming the results announced by the company on August 11, 2021 when compared to conventional liquid fuels, are now available at: https://www.quadrisefuels.com/biomsar/references/.

bioMSAR Test Highlights:

  • Engine efficiency was higher (up to 7%) than with marine diesel, increasing with engine load.
  • Average calculated CO2 emissions were 26% lower than diesel on a life-cycle (“well-to-wake”) basis, due to a combination of the 40% renewable glycerine content of bioMSAR and the higher engine efficiency.
  • NOx emissions were lower than for prior HFO and MSAR tests, and comparable to diesel, with further NOx optimisation possible.
  • Smoke and particulate levels were very low, as were unburned hydrocarbons emissions, due to efficient fuel combustion.

The existing diesel engine fuel pumps and injectors worked well with bioMSAR.

The bioMSAR test utilised 5 tons of bioMSAR manufactured at the Quadrise Research Facility, formulated with the intention of achieving a 20% CO2 reduction and the results presented are in comparison to diesel at 75% load, which is a typical operating regime for a marine 4-stroke diesel (testing range of 50% to 90% load).
