| 1. A method of generating electric power, comprising:
providing an amount of fuel to start an internal combustion engine as a function of engine temperature, the engine including
a number of combustion chambers and corresponding reciprocating pistons;
determining initial operation of the engine as a function of rotational engine speed in response to said providing;
controlling engine acceleration from the initial operation to reach the target engine speed at a target time, wherein the
controlling engine acceleration comprises reducing fuel provided to the engine before the target engine speed is reached to
reduce smoke output by the engine; and
driving an electric power generator with the engine.
