Recommendations for Heavy Fuel Oil
Cat 3600 Series engines can burn a wide range of heavy fuel oils. The 3600 Series engines that are configured for using heavy fuel oil have a special fuel system. The engines also have special components for the combustion chamber. These features help to resist the corrosive elements that are found in heavy fuel oil. Because of those special features, DO NOT use heavy fuel oil in 3600 Series engines that are configured to use distillate fuel. DO NOT use heavy fuel oil in C280 Series diesel engines.
Heavy fuel oil, residual fuel, or blended fuel can be used in Caterpillar 3600 Series diesel engines that are configured to use heavy fuel oil.DO NOT use these types of fuel in 3600 Series diesel engines that are configured to use distillate diesel fuel. DO NOT use heavy fuel oil in C280 Series diesel engines. Failure to follow this recommendation will result in severe wear of components and engine failure.
Do not use these types of fuel in engines that are Tier 4 EPA certified.3600 Series engines that are properly configured can operate on fuel which is within the specifications that are listed in Tables 1 and 2. Table 1 lists recommended specifications for heavy fuel oil that will help to provide maximum service life and performance. Table 2 lists the maximum bunkered fuel limits. If the fuel exceeds the limits that are listed in the Tables, Cat recommends diluting the heavy fuel oil with a distillate diesel fuel.
Cold-soaked starts occur when the engine has not been operated for a time, allowing the crankcase oil and the fuel to become more viscous due to cooler ambient temperatures. Consult the factory if the viscosity of the cold-soaked fuel in the fuel system will be above 20 cSt.
Note: All fuel grades listed in Tables 1 and 2 require appropriate fuel treatment prior to delivery to the injector. For information on fuel treatment see "CIMAC Background Design and Operation of Heavy Fuel Treatment Plants for Diesel Engines".Note: For more information on operating a 3600 Series engine with heavy fuel oil, see Special Instruction, REHS0104, "Guidelines for 3600 Heavy Fuel Oil (HFO) Engines".
