OREANDA-NEWS. Rolls-Royce and Claas have signed a project agreement for the supply of MTU engines to be used in agricultural vehicles. The engines will comply with the EU Stage V emissions standard due to come into force in 2019. Claas will be fitting the new improved MTU Series 1000 to 1500 engines to its Lexion and Tucano combine-harvesters, its Jaguar forage-harvester and its 4x4 high-horsepower tractor Xerion. MTU’s Series 1000, 1100, 1300 and 1500 are based on Daimler OM 93x and OM 47x commercial vehicle engines and cover a broad power range from 100 to 480 kW. From 2019, a total of 4,000 to 5,000 engines are to be supplied per year across all series and emissions levels. The MTU brand is part of Rolls-Royce Power Systems.

Bernd Kleffmann, Head of Systems Engineering Development at Claas Selbstfahrende Erntemaschinen GmbH, said: "With an eye, among other things, to the EU Stage V Emissions Directive, we have decided in favour of these tried-and-trusted engines from MTU to power a large proportion of our vehicles. We already have over 10 field-trial vehicles fitted with EU Stage V MTU engines and are very satisfied with them."

Bernd Kr?per, Vice President Industrial Business including Construction & Agriculture at MTU, said, "We are delighted at winning one of the most renowned agricultural machinery manufacturers for the EU Stage V engines we’ve introduced. This is a continuation of our long-standing success story with Claas."

As well as reducing the mass of particulate in exhaust gases, the EU Stage V regulations due to come into force in 2019 are also intended to put a limit on the number of particles. The engines meet these tighter emissions limits, in particular, by having an additional diesel particulate filter and thanks to internal design improvements intended to reduce fuel consumption.
