Bukh DV36RME Three-Cylinder SOLAS Lifeboat Diesel Package

Description

A heavy three-cylinder crankshaft balances combustion pulses to propel large enclosed lifeboats through storm-tossed coastal seas. The Bukh DV36RME Marine Lifeboat Diesel Package generates 36BHP continuous output at 3,600 RPM via an inline Bosch injection pump. This 1.45L cast-iron unit requires manual sump pump operation and regular valve clearance checks instead of automated plug-in diagnostic support.

High-strength cast iron forms the parent-bore three-cylinder block and rigid head casting to absorb high drop forces during davit release. Dry weight reaches 540 lbs within a compact equipment stance measuring 36in long by 20in wide and 26in high. The keel-cooling jacket circulates 1.80 gallons of coolant through water-cooled exhaust paths, while an isolated ground 12V 1.4 kW starter and 50A alternator protect shipboard electrical loops.

Key Features of Bukh DV36RME

Commercial vessel owners buy Bukh DV36RME diesel packages to equip large passenger ship evacuation craft. Direct factory package pricing includes a matched PRM marine gearbox to lower total repower labor inside survival vessel engine boxes.

• Mechanical Bosch inline injection pumps deliver fuel without reliance on electronic engine harnesses.
• Three inline cylinders deliver smoother torque transfer than twin-cylinder units to reduce drivetrain vibration.
• Closed keel-cooling passages protect internal block water jackets from silt and floating harbor debris.
• An included PRM reverse-reduction gearbox provides mechanical shifting control for forward and reverse maneuvers.
• Water-jacketed exhaust manifolds suppress ambient engine compartment heat inside enclosed survival hulls.
• A fixed manual oil drain pump empties the 1.22 gallon wet sump without bilge mess.
• The 12V 1.4 kW electric starter cranks the 1.45L displacement through cold weather sea deployments.

Three Cylinder Dynamometer Bench Data

Continuous dyno testing at 3,600 RPM logs 36BHP mechanical power with exhaust pyrometer readings stabilizing at 895°F before the water-cooled discharge riser. The 1.80 gallon keel-cooling circuit keeps cylinder wall temperatures at 176°F under sustained full-load water brake absorption. Crankshaft torsional vibration measurements stay within 0.05 degrees, proving smooth balance shaft dynamics across the three inline cylinders. Oil pressure stays firm at 50 PSI across main bearings during forty-degree extreme tilt trials, ensuring complete lubrication during steep sea survival launches.

Manual Controls Sump Drainage Protocol

Manual throttle linkage controls require 6 lbs of movement force to overcome internal governor resistance from neutral to wide-open run. Do not install this high-speed lifeboat diesel in continuous commercial river pushboats or offshore fishing trawlers that demand low-RPM shaft torque and slow wheel rotation.

• Drain the 1.22 gallon crankcase oil sump using the manual pump every 150 operating hours.
• Inspect the keel-cooling heat circuit and replace thermostat seals every 12 calendar months.
• Adjust cold valve lash settings on the cast iron cylinder head every 1,000 engine service hours.
