As all settings and adjustments within the combustion and scavenging
processes are made electronically, future adaptations are possible simply
through changes in software, which could be easily retrofitted to existing
RT-flex engines. A possibility is to offer different modes for different
emissions regimes. In one mode, the engine would be optimized for
minimum fuel consumption while complying with the global NOx
limit; then, to satisfy local emissions regulations, the engine could be
switched to an alternative mode for even lower NOx emissions while
the fuel consumption is allowed to rise
