Lombardini LMG18000 20kVA Marine Diesel Generator Package

Description

Cast iron cylinder block metallurgy reinforces the Lombardini LMG18000 Marine Generator Package. This four-cylinder 1.372-liter auxiliary diesel power plant delivers 16.0 kW continuous three-phase power with 20.0 kVA peak capacity at 3,000 RPM. Engineered for motor yachts and passenger vessels, it maintains stable 400-volt 50 Hz electrical power to run central chillers, hydraulic thruster power packs, and commercial galleys without voltage droop.

Heavy-duty compacted cast iron forms a rigid foundation to resist structural distortion during high-load marine cycles. The internal reciprocating train features a forged chrome-moly crankshaft, heavy-section connecting rods, and oil-jet cooled forged aluminum pistons. Technical specifications include a 72 mm bore, 84 mm stroke, 22.8:1 compression ratio, 4.0-quart oil capacity, and dry net weight of 507 lbs inside its acoustic capsule.

Key Features of Lombardini LMG18000

Yacht builders buy Lombardini LMG18000 generator packages to deliver balanced three-phase electrical power without excess engine mass. This modern turnkey package matches high electrical demand while holding engine room sound levels down to quiet conversation volumes.

• 16.0 kW continuous 400-volt three-phase output balances electrical phases across commercial machinery without phase drop.
• Brushless revolving field alternator utilizes electronic voltage regulation to hold line voltage within one percent.
• Sealed acoustic housing suppresses internal operational noise down to 54 decibels at seven meters distance.
• LMG18000 marine generator package digital controller tracks oil pressure, water temperature, AC frequency, and runtime.
• Cupronickel tube-and-shell heat exchanger prevents raw seawater from entering inner cast iron engine cooling channels.
• Single-side maintenance face organizes oil filters, fuel filters, and zinc plugs behind one fast latching door.
• Water-cooled cast iron exhaust elbow isolates extreme exhaust heat from composite yacht bulkheads.

Three Phase Alternator Load Performance

Operating at an exact 3,000 RPM governing point, this four-stroke diesel maintains steady 50 Hz current standards. Full electrical output yields 16.0 kW (20.0 kVA at 0.8 power factor) across 400-volt lines. Measured fuel burn records 0.95 gallons per hour at half load and 1.70 gallons per hour at full continuous rating. The pressurized lubrication circuit maintains 35 to 55 PSI hot oil pressure, shielding critical crankshaft and camshaft journals from friction during non-stop offshore operations.

Engine Bed Machinery Clearances

Outer dimensions measure 860 mm long, 520 mm wide, and 610 mm high within its heavy sound enclosure. Four captive marine mounts detach engine harmonics from stringer frames. The 2-inch wet exhaust fitting requires direct fall to waterlock silencers, and side panels require five inches of technician working room.

Scheduled Marine Service Instructions

Prime fuel passages using the hand pump primer to expel air pockets before turning the starter motor. Fill freshwater circuits completely to avoid localized cylinder head hot spots. This generator package is not engineered for non-marine installations, raw seawater engine blocks, or unventilated bilge holds.

• Drain factory break-in oil and install replacement lube filter canisters after the first 50 engine hours.
• Inspect flexible sea water pump impellers and drain water collection bowls every 200 engine hours.
• Descale heat exchanger tube bundles and replace internal protective zincs every 12 months.

Factory Warranty Crate Inventory

Lombardini covers this equipment with a 24-Month limited marine manufacturer warranty. The wooden shipping pallet contains the complete generator package, acoustic sound shield, digital remote station, flexible fuel line kit, factory load bank test report, and operator service documentation binder.
