Abstract

Common rail systems in diesel engines offer several advantages over traditional fuel injection systems, such as older mechanical injection systems. These advantages include precise fuel injection control, higher fuel efficiency, reduced noise and vibration, lower emissions and many other advantages. One type of heavy equipment that has used the common rail system on its engine is the WA500–3 wheel loader. One of the WA500–3 units experienced problems with symptoms of unstable low engine speed and low power. This causes disruption in the operation of the wheel loader thereby reducing its productivity. In order to overcome the problem so that the unit can operate again at maximum capacity as well as increase knowledge and understanding in dealing with disturbances in the common rail diesel engine system, it is necessary to conduct a more in-depth investigation of this problem. This problem is overcome using a eight-step troubleshooting method, namely: Troubleshooting chart, Possibility Cause, Observe and Diagnostic, Collect Data, Analysis, Suspected Cause, Conclusion, and Action to Improvement. Through this troubleshooting process, the cause of the problem was found in the pressure limiter which had a worn out valve guide causing pressure leak from the common rail system which in turn causing low pressure in the injectors. The injectors cannot supply the cylinders with adequate fuel which then shown the symptom as engine low power. Repairs were made by replacing the pressure limiter.
