“No Harm” declaration from Hochschule Wismar: 2022

18th May, 2022: Hochschule Wismar in Germany have tested SulNOxEco™ Fuel Conditioner in a marine engine and concluded no harm was noted


Hochschule Wismar is a world-leading institution with a rich 600-year heritage and with innovation being a key trademark. In the marine sector, the University is recognised globally for its research & development and engagement with industry to resolve various problems in Shipping.


In summary of the test, a representative at Hochschule Wismar states, “SulNOx additives clearly show in a MAN 6L23/30 research engine that no negative effect on operating behaviour was found even after the 2-day test operation using 4,000 litres of fuel. The comparison of the cylinder pressure curves (both Propeller and Generator) at the 75% load point show a trend that would correspond to the desired effect of the additive package. Long-term tests with SulNOx are worthwhile.”


The benefits of SulNOx’s additive package include emulsification of free water in the fuel, added lubricity to decrease wear on engine parts leading to reduced emissions and improved fuel efficiency.


Jimmy Redman of SulNOx Fuel Fusions Ltd and inventor of SulNOx technologies states, “As well as the all-important conclusion that SulNOx caused no harm to the engine, additional observations such as comparisons of cylinder pressure curves are important as they indicate lower peak combustion pressure and temperature. A smoother more even combustion phase, free from violent uncontrolled peaks reduces strain on bearings and connecting rods, a trait that can only comfort technicians and point to better engine health and reduced NOx emissions.”


Ben Richardson, CEO of SulNOx, states, “SulNOx’s products and solutions are receiving strong interest from the Shipping sector particularly with increasingly strong climate ambitions and upcoming regulatory requirements stipulated by the International Maritime Organisation (IMO) to reduce fuel consumption, CO2 and other greenhouse gases.


We have already shown in tests conducted by Lloyd’s Register that SulNOxEco™ Fuel Conditioners do not impact ISO 8217 global marine specifications, and now the results from Hochschule Wismar clearly show we do no harm to engines. We have listened and engaged extensively with the Shipping industry and now that we have alleviated their main concerns of fuel compatibility and “no harm” to engines, SulNOx must now surely be considered as a significant part of their strategy to decarbonise immediately.”
