Marine Inboard Engines
D4 Series
The Volvo Penta D4 Series offers a line of in-line 4-cylinder, 3.7-liter diesel engines using common-rail fuel injection, double overhead camshafts, and turbo. This contributes to excellent operating economy, high reliability and long-term durability.
Product Highlights
- Immediate response and high performance is matched by lower amounts of noise and vibrations further reduced by the balance shaft and the optimized engine suspension.
- The engine is extremely compact for its large swept volume. The rigid cast-iron cylinder block and cylinder head, balance shaft, and exactly controlled fuel injection give excellent onboard comfort.
- The unique marine torque of the Volvo Penta diesel engines stands out among the competition by offering increased load-carrying capability, rapid acceleration, and the ability to maintain a high cruising speed, irrespective of load or sea state.
- The high-tech fuel injection system helps make the engine highly fuel efficient. The control unit monitors several parameters which reduces the overall fuel consumption.
- A propulsion system from Volvo Penta is easy to maintain. Our comprehensive range of high-quality oil, lubrication and coolant ensures uptime and top performance in the long term. Accessories include a fuel pre-filter to keep the engine in good condition.
