Abstract
A fuel mixing occurrence detection device is provided. The device includes a fuel-type identification unit that identifies a type of fuel injected into a vehicle by comparing a fuel pump drive RPM for achieving target fuel pressure with a predetermined reference value upon starting of the vehicle. A communication unit transmits a fuel mixing occurrence to an in-vehicle controller in response to determining that the fuel mixing has occurred.
