Knock prevention and increase of reliability and efficiency of high power gaseous internal combustion engines

Main research targets of the project are as follows: to work out knock model for its prediction and to work out effective methods for knock reduction in high power output gas fuelled stationary engines for heat and power generation. Academic and commercial R&D centres herein undertake the investigation of the reduction of the abnormal combustion phenomena of knock in internal combustion engines. Combustion knock limits the efficiency of the engine and deteriorates engine performance while simultaneously contributing to engine destruction, thus it crucially reduces engine reliability. Reducing or eliminating combustion knock increases durability and also engine efficiency, hence reducing CO2 emissions. The inter-sectoral research encompassed in this proposal concerns high-power stationary engines fuelled with gaseous fuels (biogas, natural gas, coke gas) working in combined heat and power (CHP) systems. As result of the synergies and breadth of expertise, a resultant acceleration in research finding is expected with complementary investigation conducted within both the companies (Wartsila, AVL, Motortech) and universities involved that finally should result in successfully solving the related challenges. Importance to society Creation amongst the project participants of a strong science-engineering group is planned. It will initiate academic-industry based cluster with the aim to extend collaboration in the field of power and combustion engines. Hence, both local and global societies should benefit from access to knowledge that leads to well-educated people. Participation in Researcher's Nights is one of the measures taken in this case. By solving scientific and technoological problems dealing with the combustion knock, the engine will work more efficiently and more reliably. Hence, the engine consumes less fuel, what implies to the following: - it generates more power, hence reduces risk of energy defficiency - and emits less toxic pollutants as well as CO2, Therefore, it contributes to reduce impact of power generation by gas fueled engines on natural environment, so increases comfort of living for people. The overall Objectives The main project objectives are as follows: 1) to obtain a synergy and extended interaction by joining several scientific and engineering disciplines to investigate the attributes and causality associated with abnormal combustion in the internal combustion piston engine. 2) Specific technological objectives of the project are: to recognize details associated with combustion knock, to determine methods for knock prediction and reduction, 3) to stimulate collaboration between industry and academic entities.
