Diesel Engine Series 50 and 60 for Petroleum Applications

Electronic Engine Controls.The Way To Control Profits.Complete Control WithThe DDEC SystemDDEC is a complete, integratedengine management and controlsystem. The functions of DDEC canbe easily categorized:I N P U TInput to DDEC comes from a variety of sources:■ The machine operator■ The machine itself■ Engine sensorsThese inputs flow to the Electronic Control Module(ECM), which is mounted on the engine. The ECM isa powerful yet simple computer.A N A L Y S I SThe ECM analyzes the input from the sources mentioned. Itanalyzes hundreds of inputs every second and knows whatthe machine operator would like the machine to do, whatthe machine is doing, the temperature of the engine, RPM,oil pressure, load factor and so on.The ECM then comparesthis input to the data stored in its memory.O U T P U TThe commands from the ECM activate each fuelinjector. Each fuel injector is instructed to inject agiven amount of fuel at a given time.Display Every Event W ithElectronic ControlsDetroit Diesel offers an electronicdisplay that can replace a typicalmechanical instrument panel. Inaddition, the Detroit Diesel electronicdisplay will indicate any problem with ascript message. The engine ECMrecords every significant event withinits built-in memory. It’s a simpleprocedure for a service technician, oreven the machine operator, to accessand display the information andquickly locate a problem.Detroit DieselElectronic Controls(DDEC)DDEC is a complete, integrated enginemanagement and control system.DDEC IV, the fourth generation ofDDEC, is now standard equipment onall Series 50, Series 60, Series 2000,and Series 4000 engines.DDEC Features And Benefits■ Fewer parts improves reliability■ No adjustments or tune-Upsmeans reduced downtime■ Improved fuel economy■ Engine protection helps avoiddamage to engine, transmissionor machine■ Torque limiting helps savedrivetrain components■ Self diagnosis■ Engine overspeed■ Maintenance Alert System (MAS)■ Half-engine idle for rapidwarm-up■ Reduced emissions and cold startsmoke control■ Built-in and remote PTO control■ Starter lock-out■ RPM limiting capability■ Variable speed or limiting speedgovernor options■ Pressure-sensing governoroption■ Ether injectionFilter and Fluid Checks withMaintenance Alert System■ Checks oil and coolant levels■ Checks pressure drop across thefuel and air filters■ In-cab monitor for quick view ofoperating status■ Maximizes filter change intervals■ Extends maintenance intervals tothe maximum safe limits■ Eliminates costly, away-fromhomemaintenance interventionsGreen light indicates system checked andwithin preset specifications.DDEC illuminates a red light indicatingexactly what the maintenance departmentmust check. No hassle, no guesswork, nowasted downtime.Sensors monitor oil level, coolant level, andpressure drop across the fuel and air filters.Maintenance Alert System simply mountsunder driver seat for quick and easyviewing.
