Volvo Penta D6-440 – Inboard Diesel Engine 440 HP

Description

With 440 hp at 3,700 rpm, the Volvo Penta D6-440 combines a 5.5L inline six-cylinder diesel configuration with turbocharging, supercharging, and aftercooling. Common rail injection, a 17.5:1 compression ratio, and EN 590 diesel define the supplied fuel-system specification. The listed propulsion arrangement includes hydraulic transmission, an HS85A shaft interface, SAE 4 flywheel housing, and EVC electronic steering compatibility.

The 625 kg dry engine uses a 12V 150-amp alternator, heat-exchanger cooling with 16L coolant capacity, and a water-cooled riser exhaust system. Pressure-feed lubrication holds 20L oil. The supplied specifications list EPA Tier 3 and IMO II emissions ratings, with a 1-5-3-6-2-4 firing order for this inline six-cylinder engine.

Key Specifications of the Volvo Penta D6-440 Marine Diesel Engine

• The 5.5L inline six-cylinder engine produces 440 hp at 3,700 rpm through turbocharged, supercharged, and aftercooled diesel operation.
• Common rail injection and EN 590 fuel requirements define the supplied fuel-system configuration for the stated 17.5:1 compression ratio.
• An HS85A shaft interface requires drivetrain compatibility review alongside the hydraulic transmission and SAE 4 flywheel housing.
• EVC electronic steering compatibility requires control-system planning within the complete propulsion and vessel-electronics installation package.
• The 12V 150-amp alternator provides the stated charging output for vessels using this engine electrical-system configuration.
• Heat-exchanger cooling holds 16L coolant, while the water-cooled riser defines the specified exhaust-system arrangement.
• Pressure-feed lubrication uses 20L oil capacity, requiring engine-room access for scheduled fluid maintenance and inspection.

Engine Configuration and Service Access

This Volvo Penta marine diesel engine uses 103 by 110 mm bore and stroke dimensions in an inline six-cylinder, four-stroke layout. The turbocharger, supercharger, aftercooler, common rail system, heat exchanger, water-cooled riser, and alternator should remain accessible after final installation.

The 625 kg dry weight, hydraulic transmission, HS85A shaft interface, EVC controls, cooling system, and pressure-feed lubrication should be planned as one propulsion package. Engine-bed loading and clearance require review before the engine is positioned.

Why Choose the Volvo Penta D6-440 Marine Diesel Engine

The D6-440 marine diesel engine combines 440 hp with a 5.5L inline six-cylinder platform using turbocharging, supercharging, aftercooling, and common rail injection. Buyers comparing shaft-drive propulsion systems can assess its HS85A interface, hydraulic transmission, EVC compatibility, 12V 150-amp alternator, and SAE 4 flywheel housing. The supplied 625 kg dry weight and 16L coolant capacity support installation planning.

Installation and Compatibility Considerations

Confirm that the vessel supports the supplied 625 kg dry engine weight, SAE 4 flywheel housing, hydraulic transmission, HS85A shaft interface, and EVC electronic-control arrangement. Plan engine beds, shaft alignment, propeller matching, fuel supply, cooling-water intake, water-cooled riser routing, 12V wiring, ventilation, and clearance around forced-induction components before installation.

Use fuel meeting EN 590 requirements. Confirm provisions for 16L coolant capacity, 20L oil capacity, hydraulic transmission servicing, and access to the common rail system, turbocharger, supercharger, aftercooler, cooling system, and electrical components.

Warranty and Support

Warranty coverage should be confirmed against the current Volvo Penta warranty policy applicable to the exact engine, purchase market, installation, and operating use.
