Inverter generator

A generator comprising:

• an internal combustion engine comprising:
• an engine block including a cylinder comprising a piston;
• a crankshaft coupled to the engine block and configured to rotate about a crankshaft axis in response to movement by the piston;
• and
• a spark plug configured to periodically generate a spark to ignite fuel in the cylinder to control the movement of the piston;
• an alternator comprising a rotor and a stator, the rotor configured to rotate with the rotation of the crankshaft to generate alternating current electrical power;
• a starter battery configured to supply power to the alternator, wherein the rotor is further configured to rotate the crankshaft using power from the starter battery to start the internal combustion engine;
• and
• a controller configured to:
• receive an indication of a fuel type;
• and
• adjust a spark generation timing of the spark plug based on the indication of the fuel type.

• a controller configured to:
• detect an electrical load;
• before starting the engine, determine a target starting speed of the internal combustion engine based on the detected electrical load;
• and
• control a rotation speed of the rotor based on the determined target starting speed.
