Patent ID: 8322327

Claim:
A genset system comprising: an engine that is capable of running on fuel that includes at least one selected from the group consisting of gasoline and alcohol; a generator that is driven by the engine; an intake system that receives air and is in fluid communication with the engine; a fuel injector that injects the fuel into the intake system so as to form an air/fuel mixture within the intake system, an electronic control unit, an air flow sensor that measures an air flow of the intake system, an alcohol sensor that measures the amount of alcohol in the fuel that is supplied to the fuel injector, a first communication circuitry linking the electronic control unit and the alcohol sensor, a second communication circuitry linking the electronic control unit and the fuel injector, and a third communication circuitry linking the electronic control unit and the air flow sensor, and wherein data from the alcohol sensor and air flow sensor are transmitted to the electronic control unit via the first and third communication circuitry, wherein the electronic control unit is configured to determine a requested relative air to fuel ratio based on the data from the alcohol sensor and the data from the air flow sensor, the requested relative air to fuel ratio being a ratio of the actual air to fuel ratio to a stoichiometric air to fuel ratio, and based on the determined requested relative air to fuel ratio, the electronic control unit is configured to actuate the fuel injector via the second communication circuitry such that the fuel in an amount sufficient for obtaining an air/fuel mixture that is at the determined requested relative air to fuel ratio is injected into the intake system, wherein the engine provided with the air/fuel mixture that is at the determined requested relative air to fuel ratio is capable of starting and operating from a cold state.
