Intermediate result of WP4 (achieved) : Test of the Drop-in capability of IDEALFUEL

Result from partner T4F.

This result has been achieved in September 2021 in month 16 of the project (results documented in Work Package 4 of the planned result: Characterisation of lignin based engine fuels).

Partner Tec4Fuels GmbH (T4F) has set up a non-motor hardware-in-the-loop test rig for marine fuels in the EU research project IDEALFUEL and successfully performed a first test run with marine gas oil as reference fuel. Over a test run time of 100 hours at a pressure of 1,000 bar, no incompatibilities arose with the materials of the fuel-carrying components. More information can be found below.

T4F conducts the hardware in the loop testing in the current project to identify the material compatibility and the drop-in capability of the developed biogenic heavy fuel oil (Bio-HFO) within the IDEALFUEL project. Different blends of Bio-HFO with the base line fuels will be tested (in-line with the specifications of marine fuels in the fuel standard ISO8217). In this regard, the initial commissioning of the testbench according to the 4-stroke engines is completed we’re happy that the first tests with the baseline fuel Marine Gasoil (MGO) have been completed successfully.

  • Objective: To test the drop-in capability of the fuel with the 4-stroke engine components
  • Research: The fuel samples will be tested in a non-engine Hardware-in-the loop (HiL) test bench. The testing of the fuel´s material compatibility (metals, polymers) of the fuel leading components is carried out with as low as 30 liters and the primary focus will be on the high-pressure pumps of the engine.
  • Result: The testbench commissioning is completed and the initial test with the baseline fuel MGO is completed. No material incompatibilities have been observed. The test for 100 h at 1000 bar is completed successfully.
  • What will it be used for: This result will be used as a reference case for the experiments that will be conducted with the blends of IDEALFUEL.
  • Impact: A simplified (HiL) method has been developed to test the material compatibilities of the Novel fuels with the marine sector infrastructure with minimum fuel requirement and limited testing times. This method would imply the drop in capability of the fuel in the current and future market infrastructure.
