Lombardini KDI1903TCR-MP Turbo Common-Rail Marine Diesel Package

Description

Need high-pressure common-rail injection torque? Choose the Lombardini KDI1903TCR-MP Marine Diesel Package to propel commercial aquaculture vessels and service barges. The 1.9-liter inline three-cylinder turbo diesel generates 75 continuous brake horsepower at 2600 RPM. Common rail electronic injectors burn 3.8 gallons per hour at full continuous throttle, providing superior operating economy across long working days.

High-tensile gray cast iron provides rigid block architecture without excessive chassis mass. Induction-hardened parent bores eliminate cylinder distortion under continuous turbocharger boost. Sea water circulates through a corrosion-resistant cupronickel tube heat exchanger. Dry engine weight measures 485 lbs. Sump volume holds 9.0 quarts, while fuel lines connect via #6 JIC male fittings.

Key Features of Lombardini KDI1903TCR-MP

Aquaculture operators buy Lombardini KDI1903TCR-MP inboard engine systems to power mussel harvesters, oyster barges, and harbor utility craft. The broad low-end torque band provides exceptional pushing power when positioning heavy work platforms against tidal surges.

• 1600-bar common rail fuel systems atomize diesel into micro droplets to maximize combustion chamber expansion
• Wastegate turbochargers generate high manifold boost across low engine speeds to move heavy hulls
• Top-access canister filters speed up lube oil changes inside cramped commercial vessel motor boxes
• Lombardini KDI1903TCR-MP electronic controllers broadcast engine load data straight to digital bridge displays
• Cupronickel tube heat exchangers resist ocean corrosion with internal sacrificial zinc pencil protection
• Four-valve cylinder heads improve volumetric efficiency to lower exhaust emissions under continuous load
• Gear-driven bronze seawater pumps provide steady cooling flow without relying on rubber drive belts
• Four-point isolation engine mounts absorb torsional vibration before hull stringers receive engine harmonics

Combustion Profile Heat Dispersion

Electronic common-rail metering generates 162 lb-ft of continuous torque at 1800 RPM to swing heavy four-blade propellers. Thermostats regulate closed cooling circuits between 165°F and 185°F. Seawater heat exchangers shed 5,200 BTU per minute into raw cooling discharge lines, maintaining a lean 218 g/kWh specific fuel burn rate.

Stringer Drop Exhaust Geometry

Mounting brackets span across 18.5-inch engine bed stringers on threaded vibration isolation studs. The wet exhaust elbow connects to 3.0-inch marine exhaust hose adhering to ABYC P-1 standards. Clearances require at least 2.0 inches of open air gap beneath the pressed steel oil pan.

Operating Protocol Negative Filter

Electronic helm controls provide instant throttle pickup for delicate vessel maneuvering around fish farm pens. Visual inspection through clear sea strainer covers must confirm raw water flow before starting. This turbocharged diesel package is not engineered for light planing skiffs, dry uncooled stacks, or operation beyond 2600 RPM.

• Inspect sea water pump impellers for wear each shift
• Drain water accumulation from primary fuel filters every 50 hours
• Install fresh lube oil and spin-on filters every 250 hours

Warranty Statement Package Inventory

The commercial warranty protects vessel owners for 2-Year or 2000-Hour operating terms. The export crate contains the marine engine, four vibration isolation mounts, digital helm display panel, intermediate wire harness, oil sump drain hose, and official factory service manual.
