摘要：
A genset system that includes a genset assembly, an electronic fuel injection (EFI) system and an alcohol sensor and a method of controlling air-to-fuel ratio using the genset system are described. The genset assembly includes a genset engine that (1) is capable of running on at least one of gasoline and alcohol, (2) is an air-cooled engine, and (3) operates at a rich air-to-fuel ratio (AFR). The EFI system includes an electronic control unit that is configured to determine a requested AFR based on the data from the alcohol sensor and the data from the air flow sensor, and based on the determined requested relative AFR, the electronic control unit is configured to actuate the fuel injector such that the fuel in an amount sufficient for obtaining an air/fuel mixture that is at the determined requested relative AFR is injected into the intake system.
