Volvo Penta has unveiled a new 8-litre off-road industrial diesel engine with a power output of up to 160 to 235 kW. The compact Stage V version of this engine has according to the company, a "perfectly matched" exhaust after-treatment system to meet new European Union (EU) Stage V emissions regulations that come into force in 2019.
Volvo Penta, a global manufacturer and supplier of engines and powertrains for marine and industrial applications within the Sweden-headed Volvo Group unveiled a new 8-litre off-road industrial diesel engine during Elmia Wood as the next model in its EU Stage V range. The D8 is part of the full spectrum of Stage V D5, D8, D11, D13 and D16 engines, offering a power range from 105 to 565 kW (143-770 hp).
Stage V set to widen the range
With a power output of up to 160 to 235 kW, the compact Stage V version of this engine, TAD880-883VE, has according to the company “a perfectly matched” exhaust after-treatment system (EATS) to meet new European Union (EU) Stage V emissions regulations that come into force in 2019.
According to Volvo Penta, it has been developed for the future needs of customers and offers world class fuel efficiency with maximised uptime via the optimised regeneration strategy.
With Stage V regulations approaching we are continuing to move forward with our solution. Our Stage V concept is designed for customers to reap the benefits of the combination of an 8-litre engine which reduces fuel consumption and an exhaust after-treatment system that minimises emissions. The solution is easy to install, easy to operate and easy to maintain. It is optimised for our customers’ future needs, said Johan Carlsson, Chief Technology Officer for Volvo Penta during the unveiling ceremony.
The Stage V regulations for Europe will be implemented in 2019, requiring new emission limits for diesel and spark-ignition engines. The scope of the legislation is set to widen as engines below 19 kW and above 560 kW will be regulated for the first time. And while current Stage IV regulations limit the overall mass of particle emissions, Stage V will also constrain the number of particles emitted.
We’re seeing increased interest in Volvo’s engines for forest machines – primarily harvesters and chippers. But it’s also suitable for materials handling in other industries – mining, farming and more. Everywhere you need an engine that has an efficient load response that distributes the power optimally. By launching our Stage V version here today we want to show the industry that we’re a force to be reckoned with in the years to come, commented Carlsson.
A “perfectly matched” after-treatment system
According to Volvo Penta, the new engine and complementary exhaust after-treatment system (EATS) work in harmony to comply with forthcoming EU Stage V emissions standards. The EATS includes the following components: Diesel Oxidation Catalyst (DOC); Diesel Particulate Filter (DPF); Diesel Exhaust Fluid (DEF)/AdBlue injection; Selective Catalytic Reduction (SCR); and Ammonia Slip Catalyst (ASC).
With a common engine platform and high installation flexibility of the exhaust after-treatment system, our Stage V solution provides ease of installation for our customers. The engine interfaces, the electrical architecture and the wide range of options that can be chosen with our engines are compatible across different emissions levels, minimising the need of redesign of the machines for our customers regardless of where in the world they are shipping their equipment. This helps OEMs and operators move forward to the new regulations as smoothly as possible, said Carlsson.
The Stage V engine and EATS are designed to work together to maximise passive regeneration during normal operation. There is no high-temperature regeneration due to the fact that sulphur regeneration in the SCR catalyst is not required; only soot regeneration is needed to clean the DPF.
No additional fuel injector (7th injector) for sulphur regeneration is needed. This leads to increased fuel efficiency and uptime for operators.
With our EATS solution, there is no need for daily stand-still regeneration. Passive regeneration enables increased efficiency and maximises uptime for customers. This has been a major driver in our product development in order to provide a solution that helps maximise productivity for the end-users of our products in all the different applications where they operate, said Carlsson.
