Disadvantages of the ENF engine
The use of outdated refractory washers and bolts for maintenance is the cause of the well-known issue of nozzle coking and challenging disassembly.
Additionally, this series of diesel engines is well-known for accelerated camshaft wear;
The timing chain and its sprockets have a limited lifespan of approximately 200,000 kilometers; additionally, the injector and boost pressure sensor wiring frequently burns out.
