System for controlling injection of fuel in engine

A dual-fuel engine, comprising:

• a cylinder;
• a first fuel injector mounted in a cylinder head of the cylinder and configured to inject a first fuel in the cylinder;
• a knock sensor disposed on the first fuel injector and configured to generate an electrical signal indicative of at least one of a start of injection and an end of injection of the first fuel for a first injection event of the first fuel;
• and
• a controller coupled to the first fuel injector and the knock sensor, wherein the controller is configured to adjust at least one of a mass and start of the injection of the first fuel to be injected in a later, second injection event of the first fuel by the first fuel injector based on the electrical signal and one or more predefined characteristics associated with the first fuel injector.

A method for controlling an injection of a first fuel in a dual-fuel engine, the method comprising:

• injecting the first fuel via a first fuel injector into a cylinder of the dual-fuel engine;
• generating an electrical signal by a sensor disposed on the first fuel injector, wherein the electrical signal is indicative of at least one of a start of the injection and an end of the injection of the first fuel for every injection event of the first fuel;
• and
• adjusting at least one of a mass and the start of the injection of the first fuel to be injected based on the electrical signal and one or more calibration parameters associated with the first fuel injector.

A non-transitory computer readable media storing an executable code to perform a method of:

• enabling an injection of a fuel via a fuel injector into a cylinder of an engine;
• receiving an electrical signal, from a sensor disposed on the fuel injector, indicative of at least one of a start of the injection and an end of the injection of the fuel for every injection event of the first fuel;
• and
• adjusting at least one of a mass and the start of the injection of the fuel to be injected based on the electrical signal and one or more calibration parameters associated with the fuel injector.
