Volvo Penta D4-175 175HP Inboard Diesel Marine Engine

Description

During engine-room layout planning, the Volvo Penta D4-175 requires consideration of its 1,058-pound engine-only dry weight, 3.669L inline four-cylinder configuration, and 12V 115-amp alternator. Turbocharging, charge-air cooling, and common rail direct injection support the stated 175 hp output at 2,800 rpm. The thermostatically controlled heat-exchanger system, EVC network, transmission selection, and access around service components should be defined before final installation.

The supplied application data identifies low-RPM auxiliary propulsion or core mechanical drive for specified heavy-displacement motor yachts, passenger tenders, and trawlers. The stated fuel requirement is EN 590 or ASTM D975 No. 2-D diesel, and listed emissions include EPA Tier 3, IMO Tier II, and EU RCD 2. Final vessel suitability depends on the complete drivetrain, hull, shaft, propeller, and installation design.

Key Specifications of the Volvo Penta D4-175 Marine Diesel Engine

• The 3.669L inline four-cylinder engine produces 175 hp at 2,800 rpm through turbocharged and charge-air-cooled diesel operation.
• Common rail direct injection defines the supplied fuel-system configuration for the stated 17.5:1 compression ratio.
• EN 590 or ASTM D975 No. 2-D diesel supports the documented fuel requirement for this marine engine configuration.
• Volvo Penta Electronic Vessel Control requires compatible digital controls within the completed propulsion-system installation package.
• A 12V 115-amp alternator provides the stated charging output for the listed engine electrical-system configuration.
• Closed-loop fresh-water heat-exchanger cooling uses thermostatic control within the documented engine thermal-management arrangement.
• The 1,058-pound engine-only dry weight requires engine-bed and handling planning before transmission selection and final installation.

Engine Configuration and Service Access

This Volvo Penta marine diesel engine uses 103 by 110 mm bore and stroke dimensions in a vertical inline four-cylinder layout. The turbocharger, charge-air cooler, common rail components, heat exchanger, alternator, and EVC connections should remain accessible after the completed propulsion package is installed.

The supplied application data identifies dedicated low-RPM auxiliary propulsion or core mechanical drive for specified heavy-displacement installations. Final vessel suitability depends on the transmission, shaft, propeller, hull, controls, fuel system, cooling arrangement, and professional installation design.

Why Choose the Volvo Penta D4-175 Marine Diesel Engine

The D4-175 marine diesel engine combines 175 hp at 2,800 rpm with turbocharging, charge-air cooling, and common rail direct injection in a 3.669L four-cylinder layout. Buyers can assess its EVC control network, 12V 115-amp alternator, thermostatically controlled heat-exchanger cooling, and supplied 1,058-pound engine-only dry weight. The stated heavy-displacement application context provides an additional comparison point for propulsion planning.

Installation and Compatibility Considerations

Confirm that the vessel supports the supplied 1,058-pound engine-only dry weight and allows service access around the turbocharger, charge-air cooler, injection system, heat exchanger, alternator, and EVC connections. Plan transmission selection, shaft alignment, propeller matching, fuel supply, cooling-water intake, exhaust routing, ventilation, and 12V electrical wiring before installation.

Use fuel meeting EN 590 or ASTM D975 No. 2-D requirements. Verify the complete propulsion package against the intended hull and allow access to the cooling, fuel, exhaust, electrical, and control-system components for commissioning and maintenance.

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. Mulmarine.com provides product-information support before purchase and assistance with order-related questions.
