The Caterpillar 3600 Series Engine Family has been designed to provide economical operation in heavy fuel applications. The engine family consists of in-line six and eight cylinder and vee twelve and sixteen cylinder engines with ratings from 1400 to 5000 kW at speeds of 700 to 1000 rpm. It has been in production since 1985. Economical heavy fuel operation has been achieved by establishing component durability goals in conjunction with a coordinated engine overhaul strategy. Component durability has been achieved by using state-of- the-art materials at conservative temperatures. Such measures include ceramic coating of exhaust valves to provide a thermal barrier; plasma coating of the top piston ring face to provide increased scuffing and wear resistance and induction hardening of the centrifugally cast iron cylinder liner bore to provide increased wear resistance. Ceramic exhaust valve coating development included bench testing to evaluate the adhesion and chemical stability of various ceramic materials under thermal cycle and high-impurity fuel conditions. Engine testing in the laboratory confirmed the suitability of the combustion system component materials and operating temperatures with fuel viscosities up to 700 cSt (CIMAC K55 designation). This has been further confirmed by results from 3600 Series heavy fuel engines in customer applications.
