DUAL FUEL INJECTION SYSTEM CONTROL

A system for fuel injection includes a primary fuel injection system configured to inject a fuel into a cylinder of a combustion engine using a first injection technique, and a supplemental fuel injection system configured to inject the fuel into the cylinder according a second injection technique, the second injection technique being different than the first injection technique. The system also includes a controller configured to monitor a parameter of a fuel pump connected to the primary fuel injection system and the supplemental fuel injection system, and based on the parameter being greater than or equal to a parameter threshold, control a ratio of a first volume of fuel injected by the supplemental fuel injection system to a second volume of fuel injected by the primary fuel injection system during an engine stroke.
