Volvo Penta is revealing a new 8-liter diesel engine with aftertreatment system as the next model in its EU Stage V range. It 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).

The 8-liter off-road industrial diesel engine by Volvo Penta has a power output of up to 235 kW. The Stage V version of this engine, TAD880-883VE, is compact and has a perfectly matched exhaust aftertreatment system, to meet new EU Stage V emissions regulations. It has been developed for the future needs of customers and offers world class fuel efficiency with maximized uptime via the optimized regeneration strategy. 

“With Stage V regulations approaching we are continuing to move forward with our solution,” says Johan Carlsson, chief technology officer for Volvo Penta. “Our Stage V concept is designed for customers to reap the benefits of the combination of an 8-liter engine which reduces fuel consumption and an exhaust aftertreatement system that minimizes emissions. The solution is easy to install, easy to operate and easy to maintain. It is optimized for our customers’ future needs.” Stage V regulations for Europe will be implemented in 2019, requiring new emission limits for diesel and spark-ignited 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.

The new D8 Stage V engine is powerful and reliable and has been equipped with a fixed geometry turbo which contributes to reduced complexity. It achieves excellent fuel economy thanks to its efficient common rail injection, and has a power output of 160-235 kW. Maximum power and torque are available at low rpm, and the robust engine provides low noise. The air inlet throttle, together with the uncooled exhaust gas recirculation (EGR), and the electrical exhaust pressure governor (EPG) deliver highly effective heat management of the engine. This enables the system to function without the need to inject fuel into the exhaust stream to raise the temperature. With this approach, the exhaust gas has an optimal temperature when it passes through the exhaust aftertreatment system (EATS). Low heat rejection from the complete system means that less cooling is required.
