A New Method of Identifying the Limit Condition of Injection Pump Wear in Self-Ignition Engines

open access: yesEnergies, 2020
The quality or reliability of diagnostics is understood as obtaining the most likely diagnosis, and finding possible causes leading to incorrect operation of the system. In real engine running conditions it is often very difficult.
