The SOLAS range consists of the D3, D4 and D6 engines, all featuring the very latest in technology with common rail, 4-valves per cylinder and supercharging with aftercooler. The SOLAS engines are based on standard engine design with a SOLAS kit mounted and tested in factory before delivery to boat builders. The kit includes a shut off valve for crank case ventilation and a tilt switch, to be mounted on the engine room bulkhead.
The new D3 is the smallest in the range with an in-line 5-cylinder arrangement, 2.4 liter displacement and very low weight – only 260 kg bobtail. It is also equipped with a variable diameter turbo that gives the engine massive torque throughout the speed range.
D4 is the in-line 4-cylinder model with a full 3.7 liter displacement. This large swept volume provides the basis for solid performance, further enhanced by turbo and – on the high power model – also mechanical compressor.
D6 is the in-line 6-cylinder version of the D4, with all the same features in a larger size and 5.5 liter displacement.
All engines are low emission, complying with IMO, EU RCD and US EPA tier 2 regulations (R5 and/or R4).
Over the years, Volvo Penta has delivered well over one thousand SOLAS approved engines in various rescue, MOB and lifeboat applications, as well as engines to Navy and Coast Guard RIBs. All these installations require the added safety and functionality of SOLAS approved engines.
