MONITORING SYSTEM FOR IDENTIFYING AN ENGINE BANK WITH A MALFUNCTIONING FUEL INJECTOR

A monitoring system (104) obtains sensor data associated with operation of an engine (106), of a machine (102), that includes a first engine bank (110-1) with a first set of fuel injectors (112-1) and a second engine bank (110-2) with a second set of fuel injectors (112-2). The monitoring system (104) determines, based on the sensor data, a first temperature value that is representative of temperature differences between the first engine bank (110-1) and the second engine bank (110-2) for a period of time when the engine operated in a particular operation state, and a second temperature value that is representative of temperature differences between the first engine bank (110-1) and the second engine bank (110-2) for one or more prior periods of time when the engine (106) operated in the particular operation state. The monitoring system (104) determines, based on the first temperature value and the second temperature value, that a fuel injector malfunction condition occurred during the period of time.
