Lombardini KDI2504TCR-MP Turbo Common-Rail Marine Engine Package

Description

Propel commercial workboats using the Lombardini KDI2504TCR-MP Marine Engine Package to maintain continuous pushing force against river currents. The 2.5-liter four-cylinder turbo common rail diesel produces 75 brake horsepower at 2600 RPM. Precision electronic direct injection burns 3.9 gallons per hour at full continuous rating, providing exceptional operating range across demanding coastal workboat shifts.

Compacted cast iron construction creates an extremely rigid block with parent-bore induction-hardened cylinder barrels. Cast iron cross-flow heads incorporate four valves per cylinder for exceptional thermal efficiency. Cupronickel tube heat exchangers protect closed cooling circuits. Dry weight equals 562 lbs. The lube sump holds 12.0 quarts, with fuel lines connecting via #6 JIC male flares.

Key Features of Lombardini KDI2504TCR-MP

Fleet managers buy Lombardini KDI2504TCR-MP inboard engine systems to repower heavy harbor tenders and pilot vessels with modern electronic diesel machinery. The broad torque curve provides steady pulling force when spinning deep reduction marine reverse gears.

• 1600-bar common rail injection produces fine fuel atomization to eradicate transom exhaust soot
• Wastegate turbochargers supply instantaneous boost to push loaded commercial hulls onto plane
• Four-valve cylinder heads maximize volumetric efficiency to lower exhaust discharge temperatures
• Lombardini KDI2504TCR-MP CAN-bus electronics broadcast engine operating metrics to digital bridge screens
• Compacted cast iron blocks eliminate cylinder wall distortion under continuous high boost pressure
• Cupronickel sea water coolers resist marine erosion with replaceable sacrificial zinc anodes
• Top-mounted spin-on oil filters allow clean mess-free maintenance inside cramped engine bays
• Heavy-duty torsional crankshaft dampers protect marine transmission gears from diesel vibration pulses

Dynamic Torque Thermal Boundaries

Computerized common rail maps produce 221 lb-ft of continuous torque at 1600 RPM, giving propellers exceptional turning authority. Dual wax thermostats regulate internal fresh water coolant between 165°F and 185°F. Seawater exchangers discharge 5,800 BTU per minute into exhaust passages, maintaining a lean 214 g/kWh fuel efficiency rate throughout long continuous towing shifts.

Transom Stringer Exhaust Dimensions

Adjustable elastomeric vibration mounts drop onto 20.0-inch engine bed stringers with fine-pitch leveling bolts. The wet exhaust elbow connects to standard 3.0-inch marine exhaust hose adhering to ABYC P-1 standards. Clearances demand 2.5 inches beneath the stamped steel oil pan to preserve bottom drainage access.

Shift Protocols Operational Limits

Fly-by-wire electronic helms furnish immediate throttle response without mechanical cable binding. Raw water sea strainers require visual inspection through clear covers before each run. This turbocharged common-rail engine is not engineered for light sprint racing craft, dry open-air exhausts, or continuous running past 2600 RPM.

• Examine raw water pump rubber impellers each shift
• Drain water from primary fuel filter separator bowls every 50 hours
• Replace spin-on engine oil filters every 250 operating hours

Warranty Statement Shipping Inventory

Commercial users get a 2-Year or 2000-Hour limited factory warranty on base engine mechanical castings. The heavy export shipping crate contains the dressed marine engine, flexible isolation mounts, digital helm display panel, intermediate wiring loom, manual oil extraction pump, and factory service manual.
