John Deere PowerTech™ radiator-cooled, dry‑exhaust manifold engines (TF and HF models) are engineered to run vessel auxiliaries such as pumps, winches, deck cranes, and hydraulics. With displacements from 4.5 to 13.5 liters and power ratings from 74 to 448 kW (99 to 600 hp), meeting EPA Marine Tier 3 requirements has never been easier. Features - 2-VALVE CYLINDER HEAD .Cross-flow head design provides excellent breathing from a lower-cost 2-valve cylinder head - HIGH PRESSURE COMMON RAIL FUEL SYSTEM (HPCR) AND ENGINE CONTROL UNIT (ECU) .The HPCR fuel system provides variable common-rail pressure, multiple injections, and higher injection pressures, up to 1600 bar (23,000 PSI). It also controls fuel injection timing and provides precise control for the start, duration, and end of the injection -FIXED GEOMETRY TURBOCHARGER .Fixed geometry turbochargers are precisely matched to the power level and application - TURBOCHARGED .In turbocharged engines, the air is pre-compressed. Due to the higher pressure, more air is supplied into the combustion chamber allowing a corresponding increase in fuel injection which results in greater engine output -MULTIPLE INJECTION STRATEGY .The new HPCR fuel system and engine control unit (ECU) allow for multiple fuel injections. The number of fuel injections, based on speed and load, help contribute to lower combustion temperatures, which reduce the formation of NOx and particulates. The multiple injection strategy also provides an added benefit of noise reduction
