To provide sustainable solutions for power generation and global transportation, the large engine technology of the future must offer drastically reduced emissions of CO2 and air pollutants while increasing performance parameters, as well as interacting effectively with other components in holistic energy systems. In order to develop engine concepts for the next generation of high-performance large engines under these boundary conditions, it is of utmost importance that the reliability of engine concepts and components increases. The greatest challenges are the extremely high thermal and mechanical loads on components of all engines and the greater occurrence of combustion anomalies such as knock or misfire and thus the increasingly narrow operating ranges of gas engines in particular.
