Title:
METHOD FOR DETERMINING THE FUEL TYPE OF A FUEL INJECTED INTO AN INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2023/233888
Kind Code:
A1
Abstract:
The present subject matter particularly relates to a method and a control device (20) for determining a fuel type of a fuel to be injected into an internal combustion engine using a drive current of a fuel injector (5). The problem to be solved is to determine a fuel type of a fuel injected into an internal combustion engine without the application of an additional fuel sensor in the injection system. The method comprises the steps of measuring a drive current of the fuel injector (5) by a current sensor (20a), determining an opening delay of the fuel injector (5) based on the measured drive current by the control device (20), determining a fuel type of the fuel injected into the internal combustion based on the determined opening delay by the control device (20); and setting the control parameters of an injection system (100) according to the determined fuel type by the control device (20).
