Diesel Engine Injector Failures

In this example, tests were run on a GE 7FDL-16 railway engine. Individual injectors were blocked to verify that injector failures are correctly identified by AlphaSystem™.

The left dashboard shows AlphaSystem™‘s diagnostic results under normal operation at 4500 HP. The right dashboard shows the result under the same operating conditions, but with a blocked injector on cylinder R5. AlphaSystem™ is clearly able to identify the fault, and the operating condition indicator signals that overall efficiency of the engine is reduced.
