Two-stage Turbocharged Large-Bore Gas SI ICE – Operation under Different NOx Level Conditions
Original language description
Large-bore gas SI ICEs are supposed to operate under more strict conditions in terms of NOx level. Currently, the TA Luft norm is being considered while typical BMEP levels are between 22-28 bars. It is expected, that NOx would have to drop significantly (down to 50% or even 20% of the amount based on TA Luft) while engine BMEP is supposed to be increased beyond 30 bars. The paper is based on 0-D/1-D simulations while using the experience gained from older research projects between PBS Turbo and Czech Technical University in Prague. The main goal is to study the influence of different operating conditions (NOx level, BMEP level, control means, ambient conditions, and fuel composition while considering both hydrogen and CO2) on both ICE performance and turbocharger operation. Complex optimizations were carried out to achieve optimal solution for every considered operating case. General conclusions are drawn while focusing on the limits of two-stage turbocharging concept.
