Volvo Penta D3-130I-C: Precision Diesel Propulsion for Marine Excellence The Volvo Penta D3-130I-C is a state-of-the-art inboard diesel marine engine engineered for dependable propulsion in demanding aquatic environments. Introduced in 2006 as part of the proven D3 series, this robust powerplant delivers seamless performance for mid-sized vessels, combining advanced engineering with marine-grade durability. Key technical specifications underscore its efficiency and capability: Powered by diesel fuel via a sophisticated three-stage system, it produces 125 crankshaft horsepower (92 kW) from a compact 2.75-liter displacement across five inline cylinders. The M40B common rail injection system operates at pressures up to 1,400 bar, featuring medium atomization spray nozzles and electronic controls that dynamically adjust injector timing for optimal combustion. An electronically managed mechanical supercharger enhances air intake, ensuring responsive torque delivery without the lag common in traditional setups. The engine’s balanced cylinder configuration minimizes vibrations, promoting smooth operation and extended component life in saltwater conditions. For marine applications, the D3-130I-C excels in fuel efficiency, with precise injection reducing consumption and operational costs while meeting stringent emissions standards through lower particulate and NOx outputs. Its adaptive electronic high-pressure common rail technology optimizes performance across varying loads and sea states, providing stable power for reliable maneuvering in choppy waters or long-haul voyages. Reliability is paramount, thanks to the D3 series’ corrosion-resistant construction and proven track record in harsh marine environments, minimizing downtime and maintenance demands. Performance characteristics include instant throttle response from the supercharger, balanced power density for vibration-free cruising, and eco-friendly operation that complies with global regulations like EU Stage II. Ideal for recreational cruisers, sportfishing boats, and workboats up to 40 feet, the D3-130I-C offers versatile propulsion that balances speed, economy, and environmental stewardship—empowering mariners to navigate with confidence and efficiency.
