20110180041 | GENSET ENGINE USING AN ELECTRONIC FUEL INJECTION SYSTEM INTEGRATING AN ALCOHOL SENSOR - An open or closed loop EFI system integrating an alcohol sensor is provided on a genset engine. The EFI system provides acceptable engine performance and efficiency when using fuels or fuel blends over a wide band and when starting from a cold state, i.e., starting the engine after the engine has not run for a relatively long period of time. The alcohol sensor enables acceptable operation while the genset engine is cold. The alcohol sensor sends data to the electronic control unit (ECU) and this data, as well as data provided by other sensors that may be available such as an air flow sensor, is used to determine the optimal air-to-fuel ratio (AFR). The ECU actuates the fuel injector which sends the correct amount of atomized fuel to mix with the air flow to be combusted. The fuel mixture, at the requested AFR, enables the engine to start and operate efficiently from a cold state even if the fuel blend has been changed from a previous operation of the engine. | 07-28-2011 |
