Reduction of CO2 emissions in maritime shipping through the use of drop-in fuel components from waste materials – investigations into the mixture stability of pyrolysis intermediates
In April 2018, the IMO (International Maritime Organisation) set out its strategy for reducing ship-based greenhouse gas emissions in its Resolution MEPC.304. According to this, CO2 emissions are to be reduced by 40% by 2030 and by 70% by 2050 (compared to 2008). Due to the long life cycles of ships and their propulsion systems, the key to achieving these ambitious goals in the medium term lies in the defossilisation of fuels. One solution to this problem is the use of waste-based, low-sulphur ‘drop-in fuels’ for the operation of ocean-going vessels.
Objective:
Improvement of the mixture stability of pyrolysis intermediates from waste materials with marine fuels through the use of solubilisers and additives
Task:
1) Literature research on marine fuel components from waste materials and suitable solubilisers to improve mixture stability with fossil marine fuels
2) Conducting a series of measurements on the influence of additives and solubilisers on the mixture stability of pyrolysis intermediates with selected marine fuels.
a. Preparation of mixtures.
b. Testing of mixture stability over a period of two weeks.
c. Testing of mixture stability after the addition of solubilisers and additives.
- Determination of selected fuel parameters (flash point, density, viscosity)
- Comparative assessment of fuel blends in terms of their suitability as marine fuel (advantages and disadvantages)

Conversion of a single-cylinder engine from oil mist lubrication to metered oil lubrication
On a single-cylinder full engine, the existing oil mist lubrication is to be converted to oil sump lubrication with or without an oil pump.
To this end, both options are to be investigated and, after selecting a suitable variant, tests are to be carried out on the test bench motor to examine its function and effectiveness.

Design of a dual-mass flywheel for a single-cylinder internal combustion engine
A flywheel must be designed for a single-cylinder engine that dampens the resulting torsional vibrations as effectively as possible in order to minimise stress on the drive train and losses at a friction clutch, thereby increasing efficiency.
