1. A system, comprising:
an electronic compressor;
a fuel handling system including a fuel injection point positioned upstream of an intake manifold;
a bypass intake coupled between the intake manifold of an engine system of a generator set and the electronic compressor so that the electronic compressor provides suction at the intake manifold when activated so as to purge air out of the intake manifold with a mixed charge;
a bypass outlet coupled between the electronic compressor and the engine system; and
a valve positioned to selectively inhibit flow between the bypass intake and the bypass outlet during a starting operation.
