The title of this bachelor project is "Gas/luft temperaturens indvirkning på en gasmotor" (The effect of the temperature of gas/air mixture on a gas engine), and it is as a part of the final bachelor semester at the education as Bachelor of Technology Management and Marine Engineering. The education is conducted at Aarhus School of Marine and Technical Engineering, as a part of their online education program.
This bachelor project is based on a trainee period at DEIF A/S and it is made in cooperation with the company.
The project investigates the effects on a gas engine caused by a high gas/air mixture temperature, and this concerns both the operation of the gas engine and the total efficiency. In order to determine the effects, the project includes a study of another gas engine which is the exact same model as the gas engine at DEIF A/S.
In order to avoid the effects, caused by the gas/air temperature, the project contains proposals to an optimization which are based on minor changes to keep the costs down.
The conclusion for the effects, caused by the gas/air temperature, is theoretically the temperature results in degraded operation conditions and a decrease in the efficiency for the gas engine. The conclusion for the effects based on the results of the engine oil analysis, does not agree with the theory, but the reason for that is the number of the collected oil samples are too small.
The project also contains a section which describe the next step in the investigation to be able to define the final conclusion about the effects caused by the gas/air temperature and the evaluation for the optimization
