Starting engine with generator to idle speed or higher without fueling

A computer readable storage device having instructions, which when executed by a processor, cause the processor to execute:

• determining when to start an internal combustion engine of a hybrid electric vehicle;
• causing energy to be supplied to a generator/motor mechanically couplable to the internal combustion engine, to cause the generator/motor or crankshaft to rotate to at least a hold speed;
• transmitting a first instruction to an engine processor when determining that the internal combustion engine should be started, whereby the engine processor does not supply fuel to the internal combustion engine in response to the first instruction;
• transmit a second instruction to the engine processor after a variable period of time has elapse after the generator/motor or crankshaft has reached at least the hold speed, the variable period of time being based on at least on a temperature, wherein in response to the second instruction, the first processor enables fuel to supplied to the internal combustion engine;
• and
• configuring a memory device to store relationships between a plurality of temperatures and a plurality of periods of time, respectively, wherein the second processor is configured to select one of the plurality of periods of time based on a sensed temperature and set the selected one of the plurality of periods of time as the variable period of time
• wherein the second processor further receives pressure information for at least one fluid, and the second processor adjusts the selected one of the plurality periods of time based on the received pressure information for at least one fluid prior to setting the selected one of the plurality of periods of time as the variable period of time, and sets the adjusted period of time as the variable period of time.

• transmitting a first instruction to an engine processor when determining that the internal combustion engine should be started, whereby the engine processor causes fueling only while at or below a low idle speed governor influence and stops fueling when the crankshaft speed exceeds the low idle speed governor influence;
• transmits a second instruction to the engine processor after a variable period of time has elapsed after the generator/motor or crankshaft has reached at least the hold speed, the variable period of time being based on at least on a temperature, whereby the engine processor causes fueling to the internal combustion engine in response to the second instruction according to a command included in the second instruction;
