How Failed Fuel Injectors can lead to Diesel Engine Failures

In heavy-duty diesel engines, failed fuel injectors are often the starting point for a much larger chain of destructive events. Across locomotive fleets, mining haul trucks, underground mining equipment, drilling machines, marine engines, and stationary power systems, injector degradation remains one of the leading contributors to fuel dilution, thermal stress, piston damage, and catastrophic engine failures. Understanding how we can prevent their failures are of utmost importance.
