Start-up control of internal combustion engines

摘要

An electric power generation system ( 20 ) is disclosed, which includes an electric power generator ( 22 ) driven by a four-cycle internal combustion engine ( 30 ). The engine ( 30 ) includes a plurality of reciprocating cylinders (C 1 -C 6 ) each rotatably coupled to a crankshaflt ( 34 ), which drives the electric power generator ( 22 ). A controller ( 90 ) is included that is operable to control fueling to start the engine ( 30 ) as a function of engine temperature and determine initial engine start-up as a function of rotational engine speed. This controller ( 90 ) regulates engine acceleration until a target engine speed is reached from initial start-up. Once this target speed is reached, the controller ( 90 ) provides a speed governor function.
