You can trust our Volvo Penta D4 to provide high reliability, exceptional fuel efficiency and low maintenance cost. This in-line 4-cylinder, 3.7-liter diesel engine features common-rail fuel injection, double overhead camshafts and turbo. Volvo Diesel Marine Engine
High performance
Immediate response and high performance is matched by low levels of noise and vibrations, further reduced by the balance shaft and the optimized engine suspension.
Features & Benefits
Compact and robust
The Volvo Diesel Marine engine is designed and built to be immensely strong, using cutting edge technology and material. This gives high reliability and long-term durability.
Unique marine torque
Volvo Penta engines excel with their unique marine torque. High torque at low rpm gives rapid acceleration to the plane and massive maneuvering power. Even at high load and high rpm, the torque remains strong to provide efficient cruising speed in all conditions. Volvo Penta D4 Marine Diesel Engine Specifications
Volvo Penta builds the 3.7-liter D4 (150 to 320 hp) and the 5.4-liter D6 (300 to 480 hp) diesel engines for marine duty, rather than marinizing truck engines.
Both offer the long-heralded Volvo Penta advantage of existing as part of a complete propulsion system from key switch to prop, whether utilized in inboard, sterndrive, water-jet or IPS variants.
This makes for one-stop shopping when a boat owner needs parts and service.
The engines are said to burn between 1 and 7 percent less fuel than their antecedent generation and cost some 10 percent less to own. When asked just how Volvo Penta achieved these milestones,
the engineering team answered directly and with copious examples. To wit, the common rail fuel-injection system now features higher pressure—2,000 bar, which is 25 percent higher than the previous 1,600 bar.
Controlled by a new engine management -system,
this enables more precise calibration and control of injection parameters, so the engines run even smoother and are more fuel-efficient.
While other details—such as a fuel filter with a sensor, and a new a diamondlike carbon (DLC) coating on the piston pin that reduces friction and increases durability—proved cool,
Volvo diesel marine engine insight into the actual manufacturing environment. Utilizing practices such as pressurized assembly spaces to eliminate dust and grit in the air ensures the mating internal surfaces of moving parts start off with the best chance for long-term reliability.
boaters shouldn’t underestimate the deleterious effects of an errant mote or shaving at 2,800 rpm—suffice to say, so-called “clean manufacturing” methods offer concrete merits.
And the new boost/charge air system, with its larger supercharger and smoother handoff between supercharger and turbo, resulted in torque I could feel from the helm of the test boats.
