Volvo Penta launches new five and 13 litre Stage V engines

Published:  22 November, 2017

Two new engines with complementary after-treatment systems have been launched by Volvo Penta at the international agricultural machinery trade fair Agritechnica in Germany.

The five and 13-litre Stage V engines are intended to offer fuel efficiency, low emissions, productivity and reliability.

The engines join Volvo Penta’s Stage V engine range – D5, D8, D11, D13 and D16, offering a power range from 105 to 565 kW (143-770 hp).

‘As new emissions regulations are on the horizon for 2019, we know that OEMs are planning now on how to move towards this new chapter for equipment manufacturing,’ said chief technology officer at Volvo Penta Johan Carlsson.

‘With our new engine solutions, OEMs can be sure that their customers will get the right power output for their needs at the appropriate emissions levels. We offer an excellent solution for manufacturers and operators, one that will also help preserve the viability of the environment.’

The 13-litre engine – TAD1381-1385VE – is a six-cylinder unit with a maximum output of 405kW (551hp) at 1900rpm. The five-litre engine – TAD580-582VE – is a four-cylinder unit with a maximum output of 160kW (218hp) at 2200rpm.

Each is designed to deliver maximum power and torque at low rpm and is equipped with all the key features of Volvo Penta’s Stage V concept. They are compact, with hardware layout and electrical interfaces that are compatible with engines of earlier emissions legislation.

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 EATS. Low heat rejection from the complete system means that less cooling is required.
