Volvo Penta D3-110 Auxiliary Inboard Marine Diesel Engine

Description

Drive high-demand hydraulic winches and electrical alternators with the Volvo Penta D3-110 Auxiliary Engine. This 2.4L 5-Cylinder inline diesel produces 110BHP at 3,000 RPM while maintaining continuous 85BHP output at 2,800 RPM. Common-rail injection requires clean fuel supply through strict 2-micron filtration systems. Cast aluminum cylinder construction demands proper sacrificial anode protection during service.

The die-cast aluminum block houses cast-in iron liners with a crossflow 20-Valve DOHC cylinder head. Electrical power runs on a 12V isolated 2-pole system supported by a 3.0 kW starter and a 12V 150A alternator. The compact engine envelope measures 34.2in long, 27.1in wide, and 27.4in high. Total dry weight without gearbox equals 573 lbs. Oil sump volume holds 1.72 US gal of lube oil.

Key Features of Volvo Penta D3-110

Commercial marine operators buy Volvo Penta D3-110 auxiliary engine packages for dedicated shipboard hydraulic skids and heavy power generation. Fleet engineers use this inline configuration for commercial workboat auxiliary power repower projects.

• Piezoelectric common-rail injectors atomize fuel at 1,800 bar pressure for total cylinder combustion efficiency
• Variable geometry turbochargers supply positive intake boost across idle to 3,000 RPM operation bands
• Tubular freshwater heat exchangers transfer heat away from raw seawater cooling circuits
• Electronic Vessel Control monitors throttle input signals through isolated CAN-bus harness connections
• Cast-in iron cylinder liners absorb mechanical piston skirt thrust loads inside aluminum block bores
• Flexible drive couplers protect hydraulic spline pumps against torsional crankshaft vibration cycles
• Multi-rib poly-V belts drive the 12V 150A alternator to recharge heavy service battery banks

Bench Dynamometer Load Test Output

Dynamometer tests verify 85BHP continuous shaft output at 2,800 RPM with peak 110BHP available at 3,000 RPM. The variable turbine geometry maintains 1.35 bar boost pressure under sustained generator drag. Closed-circuit cooling stabilizes coolant temperature at 185°F under full thermal loading. Lube oil pressure maintains 45 PSI across high-temperature cycles. Static engine tilt tolerance reaches 30° during rough water operations. Crankshaft main journals maintain 0.0005in TIR runout to prevent bottom-end bearing wear during peak torsional deflection.

Field Operation Maintenance Rules

Electronic throttle controls react to electrical load swings with under 3 lbs of lever input force. Do not select this lightweight aluminum block for commercial workboat diesel engine repower installations requiring continuous uncooled raw river silt operation or heavy cast-iron ballast weight. Operators must provide clean filtered seawater intake feeds to protect alloy heat exchanger tubes.

• Drain engine lube oil and spin-on filter cartridges every 200 operating hours
• Inspect raw water neoprene impellers and clean brass sea strainers every 100 hours
• Replace the primary 2-micron water separator fuel filter every 250 run hours

Factory Warranty Crate Contents

Factory marine coverage includes a 2-Year limited warranty on major structural assemblies. The wooden shipping crate contains the bobtail engine core, 12V 150A alternator, 3.0 kW starter motor, four elastomeric vibration mounts, digital EVC wiring harness, dual oil pressure senders, and factory operator maintenance manuals.
