Volvo Penta offers an IMO III engine range for Volvo Penta IPS, Diesel Inboard, Marine Genset and Auxiliary applications. Based on SCR exhaust aftertreatment technology, our robust solution is designed for tough marine conditions. The system is built to cope with high sulfur fuel and sustain high back pressure, while maintaining engine efficiency and driveability.
The exhaust aftertreatment technology chosen by Volvo Penta is Selective Catalytic Reduction, SCR, which ensures high engine power and efficiency while reducing NOx. We are leveraging our knowledge of SCR technology within Volvo Penta and the Volvo Group. Our IMO III solution has been adapted to demanding marine conditions, and tested extensively at our own facilities as well as in commercial customer applications – in total 35,000 hours at the launch in 2018.
With Volvo Penta, you benefit from the simplicity of a single-supplier offer. The type approved solution is developed, certified, monitored and maintained by one company. One complete system, including all functions. One point of contact. One common engine platform. One source of aftermarket support. One tool for service technicians. One interface for operators. Volvo Penta’s Marine Commercial expert, Jan Willem Vissers is your guide.Play video
Volvo Penta’s Environmental Director Cecilia Gunnarsson explains how we can reach further, beyond compliance with the IMO Tier III regulations: “SCR technology for NOx reduction, IPS for fuel efficiency and fossil-free fuel to reduce CO2. This combination is an important step towards sustainability.”Play video
IMO III puts a focus on NOx limit, because NOx damages eco systems and poses health hazards. The Volvo Penta SCR solution reduces NOx levels by up to 75%. With SCR technology, Diesel Exhaust Fluid (DEF) is infused into the exhausts, and gases are mixed inside the SCR unit. Here, the ammonia content of the DEF/urea transforms the NOx into nitrogen and water. The systems allows for 32 or 40% urea.

We made installations very flexible. A large part of the installations will be repowering, so we have prioritized utilization of machine room space. That is why we have emphasized easy installation, with a design of the SCR unit that allows for space-efficient configuration possibilities. For easy installation, the SCR unit features multiple outlets with robust bolt flanges. You also benefit from a fully integrated system. The monitoring is integrated and values are shown on your EVC or MCC displays. The whole solution is optimized for ease of installation, operation, maintenance and service.
Volvo Penta offers IMO III for D13 in Volvo Penta IPS, Diesel Inboard, Marine Genset and Auxiliary applications. During the year 2020, Volvo Penta will extend the IMO III range with the D8 for Diesel Inboard, Marine Genset and Auxiliary applications. Both engines are designed to cope with high back pressure and high-sulfur fuel – up to 1,000 ppm. The exhaust aftertreatment system is tailored for a perfect fit. The SCR unit, also a silencer, reduces noise by up to 35 dBA. Volvo Penta has been able to fulfill IMO III targets while maintaining the same low fuel consumption. And thanks to SCR, the engine power output remains unaffected.
