EngineCaterpillar four-stroke cycle, six cylinder3056E DIT ATAAC diesel engine.Rated Net Power2300 rpmISO 9249108 kW/145 hpEEC 80/1269 108 kW/145 hpMaximum Net Power 1900 rpmISO 9249117 kW/156 hpEEC 80/1269 117 kW/156 hpBore100 mmStroke127 mmDisplacement6 liters Net Power ratings are testedat the reference conditions forthe specified standard. Net power advertised is the poweravailable at the flywheel when theengine is equipped with alternator,air cleaner, muffler and fan atminimum speed. No derating required up to 3000 maltitude. Auto derate protects hydraulicand transmission systems. When the fan is at maximum speedrated net power is 97 kW (130 hp)and Maximum Net Power is 109 kW(146 hp) at the flywheel per the SAEreference conditions.
