    "uspto_assignee": "Caterpillar Inc.",
    "patent_abstract": "A system for controlling an internal combustion engine includes an internal combustion engine configured to combust a plurality of fuels including a first fuel having a first energy density and a second fuel having a second energy density, a fuel injector configured to inject the first fuel and to inject the second fuel, and a sensor configured to generate signals that indicate combustion of fuel within the internal combustion engine. They system further includes an electronic control module configured to: receive the signals from the sensor, generate commands to cause the fuel injector to inject fuel, determine whether the injected fuel corresponds to the first fuel or to the second fuel based on the signals from the sensor, and generate adjusted commands to cause the fuel injector to inject fuel based on whether the fuel was determined to correspond to the first fuel or to the second fuel.",
    "precision_class": "structural",
    "invention_explanation": "A control system listens to combustion signals to identify which fuel is being burned, then helps the engine adjust its operation accordingly.",
