A unique engine system has an engine with a dedicated exhaust gas recirculation cylinder, an EGR system that receives exhaust gas from the dedicated cylinder, and a turbocharger having turbine inlet ports in fluid communication with other engine cylinders via a plurality of exhaust passages. At least two of the exhaust passages are substantially isolated from each other. Other embodiments include apparatuses, systems, devices, hardware, methods, and combinations for engines and engine systems.

Engine systems and methods for operating an engine

An engine generator set comprises an internal combustion engine having an output shaft that is coupled to an electrical generator for producing an AC electrical power output. The engine is operable to rotate the shaft at a first rotational speed so that the generator is driven to produce electrical power at a first frequency and a second rotational speed at which the generator is driven to produce electrical power at a second frequency. An exhaust gas turbocharger is operatively connected to the engine and has a compressor with a housing that defines a gas inlet. At least two guide, vane assemblies that are releasably and interchangeably connectable to the inlet to match the compressor performance with the first or second engine speed. The guide vanes of the first guide vane assembly extend in a downstream direction towards the impeller wheel at an angle relative to the inlet that is different to the corresponding angle of the guide vanes second guide vane assembly.
