The INNIO Group analyzes the chemical composition of residual dirt particles with ZEISS solution

"Even a tiny metallic dirt particle can cause considerable damage in our high-performance engines," emphasizes Christian Troger, Operation QUALITY LEADER at INNIO in Jenbach. If, for example, a metal particle the size of a grain of sand were to be found in the connecting rod bearing, there would be a risk of the oil film in the bearing breaking off. Without sufficient lubrication, this increases the friction between the crankshaft and the connecting rod bearing, which can lead to serious damage.

The INNIO Group sets industry-wide standards in terms of engine performance and reliability. The Jenbacher generator sets as well as combined heat, power and cooling systems in the power range from 250 KW to 10.4 MW can be operated with a variety of energy sources such as landfill gas, sewage gas, biomethane or hydrogen, paving the way for customers' transition to Net Zero.
However, the higher the efficiency and power density of the motors, the higher the peak pressures and bearing loads. The designers' answer is harder bearings and smaller lubrication gaps. However, this increases the risk of so-called killer particles causing oil film breakage.
