Volvo Penta IMOIII solution

Volvo Penta IMO Tier III solution

Optimized for marine

Volvo Penta will offer an IMO III engine range for IPS, inboard, 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.

A proven concept

A proven concept

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 20,000 hours at the launch in 2018.

Play

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.

An important step

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.”

Our SOLUTION

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. Watch the film clip to see a systems overview and how our SCR works.

FLEXIBILITY AND INTEGRATION

FLEXIBILITY AND INTEGRATION

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 twin 6-inch 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.

THE D13 IMO III RANGE

The robust Volvo Penta D13 is an engine that is 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 35-40 dBA. Volvo Penta has been able to fulfil IMO III targets while maintaining the same low fuel consumption. And thanks to SCR, the engine power output remains unaffected.

THE D13 IMO III RANGE

The outputs of the IMO III engine range span from 300 to 600 kW. The range comprises Gensets 1500/1800 rpm (1), Inboard R1-R4 (2), IPS R3-R4 (3), and Auxiliary 1500/1800 rpm plus R1-R3 (4).
