Welcome to the Oel-Waerme-Institut

OWI provides research services investigating and developing concepts and new technologies for heat and power generation on a basis of fossil and renewable fuels. It aims at developing energy-efficient and environmentally friendly products which are marketable. At the same time, OWI cooperates closely with industrial partners and research institutes and sees itself as an mediator between fundamental and applied research. OWI is a non-profit organisation and an acknowledged institute affiliated to RWTH Aachen University.


Oel-Waerme-Institut reorganizes itself –
Non-profit research for fuels continues to be the focus

17th November 2015 – The OWI Oel-Waerme-Institut GmbH has been reorganized to be prepared for the future. With the founding of the TEC4FUELS GmbH, the affiliated institute of the RWTH Aachen receives a 100-percent parent company. Shareholders of the TEC4FUELS GmbH are the Institut für Wärme und Oeltechnik (IWO) and Dr. Klaus Lucka. The focus on non-profit research projects and strategic basic research around liquid energy carriers shall be assured in the future. Within this new structure and the connection to the RWTH Aachen as an affiliated institute the OWI still represents scientific excellence. The OWI’s scientific advisory board and its management by Prof. Dr. Herbert Pfeifer remain unchanged. … More

Coking of fluid fuels –
New procedure shall analyze and avoid reasons

6th November 2015 – In heating appliances, diesel engines and other technical systems driven by fluid fuels and lubricants, combustion can lead to growing undesirable deposits (coking), which may affect the functionality of the system. Deposits arise during the evaporation of fuels on hot surfaces. The detailed processes are unclear. Within a common research project, the chair for Analytical Chemistry of the University Rostock and the Oel-Waerme-Institut (OWI) want to get to the bottom of the reasons for deposit formation in modern combustion systems. … More

Deposits in diesel-injectors –
New test shall replace XUD9 and DW10

15th September 2015 – A newly developed non-engine test bench for diesel fuel with different biofuel content is able to reproduce deposits in diesel injectors under realistic circumstances. The test method, which is used for investigations of the increasingly observed “internal diesel injector deposits” (IDID), shall replace the currently used tests XUD9 and DW10 for the evaluation of additives in No-Harm trials, because they are either expensive or no longer represent the latest technology. … More

Operating industrial furnaces with biogenic fuels –
GWI and OWI develop “biological burner”

27th August 2015 – Within a joint research project, the Gas und Wärme-Institut Essen e. V. (GWI) and the Oel-Waerme-Institut (OWI) want to develop a combined biofuel burner for the production of industrial process heat. The burner shall not only burn low calorific gas but also fluid biogenic fuels, such as vegetable oil, in an effective and safe way while producing low emissions. Development tasks include a (partly) premixing evaporation concept for conventional and biogenic liquid fuels. … More

Fuel cells in diesel operation –
System successfully tested

13th May 2015 – The research partners inhouse engineering, Enasys, MAHLE Behr GmbH & Co. KG and the Oel-Waerme-Institute (OWI) achieved an important milestone in the project completion for the development of a modular, diesel driven fuel cell system: The system’s functionality has been successfully demonstrated in the isolated operation of the fuel cell stack and of the electronics module. The fuel cell system consists of a diesel and water tank, a fuel gas generator module and a fuel cell module including a low-temperature-PEM-fuel cell (LT-PEM) with 90 cells, as well as a battery and power electronics. … More
