Natural Gas/Hydrogen blends for heavy-duty spark ignition engines: Performance and emissions analysis

Spatiotemporal insights into forced dynamic reactor operation for fast light-off of Pd-based methane oxidation catalysts

“…Transferring the fundamental knowledge gained throughout the experiments presented above into real-world applications is key for designing highly efficient reactor operation strategies. Therefore, the forced dynamic reactor operation investigated herein is applied in a complex exhaust gas mixture that mimics real conditions representative for natural gas engines 80,81 as summarized in Table 2. With the species concentrations listed in Table 2, an air-to-fuel equivalence ratio λ of 1.2 for the lean phase and of 0.98 for the rich phase was calculated according to eqn (2).…”
