Usage of heavy fuel oil (HFO) in Caterpillar Medium Speed Engines is common. Caterpillar is becoming more involved with operation/maintenance contracts in these applications. Heavy fuel oil provides significant fuel cost savings. However, the use of HFO leads to increased engine wear and shortened component life. The quality of the fuel oil is a major factor that determines engine component life. The life of engine components can be optimized by monitoring fuel quality.Demand has grown for a test kit that allows on-site testing of the heavy fuel oil. Several factors have driven the demand for a quick, accurate method of monitoring the fuel quality at the engine site:
The quality of worldwide HFO supplies is deteriorating.
On-site testing provides quick analysis of the fuel.
Testing can be used as a diagnostic tool in order to troubleshoot problems that are related to the auxiliary treatment system for the heavy fuel oil.
Testing helps prevent damage to engines due to low quality HFO.
Testing helps prevent damage to engines due to contaminated fuel.
Overall engine performance can be maximized by monitoring the fuel quality.
Accurate prediction of service intervals results in reduced maintenance costs.Caterpillar Chemical Services has evaluated several HFO test kits. Test kits are available from various sources. Caterpillar recommends the Zematra test kit for on-site testing of HFO.Caterpillar Chemical Services has determined that the following parameters are necessary for testing HFO. The test parameters are listed in order of importance.
Viscosity
Density
Water Content
Salt Water Content
Stability and Compatibility
Pour PointThe Zematra kit can test for each of the parameters that are listed. Proper use of the Zematra test kit will result in more consistent fuel quality at the engine. Consistent fuel quality will provide reduced maintenance costs and reduced repair costs.Zematra can be contacted at the following address:Zematra BV
