ASYMMETRIC FUEL INJECTION WINDOW AND FUEL METERING WINDOW

A multi-fuel injection system and method for controlling a fuel injector to perform fuel injection using a fuel injection window and to perform fuel metering using a fuel metering window that is asymmetric to the fuel injection window are provided. The multi-fuel injection system may receive a first fuel and receive a second fuel. The multi-fuel injection system may control a fuel injector to perform fuel injection, of at least one of the first fuel or the second fuel into a cylinder of an engine, during a fuel injection window. The multi-fuel injection system may control the fuel injector to perform fuel metering, of the second fuel into a nozzle of the fuel injector while the fuel injector is not injecting either of the first fuel or the second fuel into the cylinder of the engine, during a fuel metering window that is asymmetric to the fuel injection window.
