Abstract
Systems and apparatuses include a system including an electronic compressor, a bypass intake coupled between an engine system of a generator set and the electronic compressor, 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.
Claims19
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.
3 more elements
A system comprising:
- an electronic compressor;
- a bypass intake coupled between an 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;
- 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, wherein the bypass outlet is coupled between the electronic compressor and an exhaust manifold of the engine system.
2 more elements
A system comprising:
- an electronic compressor;
- a bypass intake coupled between an 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;
- 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, wherein the bypass intake is coupled between an outlet of a turbocharger compressor and the intake manifold of the engine system.
2 more elements
A system of comprising:
- an electronic compressor;
- a bypass intake coupled between an 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;
- a bypass outlet coupled between the electronic compressor and the engine system;
- a valve positioned to selectively inhibit flow between the bypass intake and the bypass outlet during a starting operation;
- a second bypass intake coupled between an air handling system and the electronic compressor and structured to provide a mixed charge to the electronic compressor;
- and
- a second valve structured to selectively inhibit flow through the second bypass intake.
4 more elements
A method comprising:
- opening a bypass valve providing communication between an engine system of a generator set and an electronic compressor;
- starting the electronic compressor to provide suction at a bypass intake that is disposed between an intake manifold of the engine system and the electronic compressor so as to further provide suction at the intake manifold;
- purging fresh air from the engine system with the started electronic compressor with a mixed charge;
- cranking a starter motor after starting the electronic compressor;
- stopping the electronic compressor after the fresh air has been partially or completely purged;
- and
- closing the bypass valve after stopping the electronic compressor.
