Rolls-Royce is presenting its EU Stage V certified MTU engines for the construction equipment and industrial sectors at bauma, the world’s largest construction machinery trade fair. Series 1000, 1100, 1300 and 1500 engines were given certificates of compliance with EU Stage V emission requirements in March 2018, and have been available as standard production engines since June 2018. The first units have already been delivered to vehicle manufacturers Tadano, Hidromek, Kato, Manitowoc, Bomag, Bell and Hyster.
Based on Daimler commercial vehicle engines, these diesels cover a power range of 115-480 kW. The new limits are achieved by internal engine enhancements and by adding an SCR system and an additional diesel particulate filter. As well as reduced CO2 emissions, the torque, performance and fuel consumption of the engines have all been improved.
“The first EU Stage V engines have been tested rigorously in numerous prototypes, at times under extreme weather and altitude conditions. This way, we've been able to evaluate a wealth of application data and operating experience, and the engines finally went into full production seven months before the new directive came into force,” explains Lars Kräft, Head of Industrial Business at Rolls-Royce Power Systems.
Positive customer feedback
After almost 110,000 hours of field testing, the first MTU EU Stage V engines are already shipping to customers, destined for a variety of applications. Hyster heavy-duty forklift trucks over eight tons, container handlers and reach stackers are to be fitted with MTU Series 1000 and Series 1100 EU Stage V engines. “The added performance will enable our European customers to streamline operations and boost productivity – whether they’re handling containers during a Swedish winter or steel pipes in the Italian summer heat,” says Jan Willem van den Brand, Director Big Truck Product Strategy & Solutions at Hyster Europe.
International articulated steering specialist Bell Equipment also recently took delivery of the first six EU Stage V certified MTU Series 1000 to 1500 engines from Rolls-Royce. As early as 2016, Rolls-Royce provided two EU Stage V prototypes for external testing at Bell, which were duly trialed in the hot, dusty climate of South Africa and endurance-tested at extreme altitudes of up to 3,000 m.
One-box solution and dual certification
Rolls-Royce offers a one-box SCR-DOC-DPF solution to integrate all components into the limited installation space of the machines. This exhaust gas aftertreatment system is both compact and robust. The box meets the requirements of vehicle manufacturers and operators by being simple to install, operate and maintain. As well as being certified to EU emission Stage V, MTU engines are also certified to the U.S. Environmental Protection Agency’s Tier 4 Final. This dual certification gives Rolls-Royce customers full flexibility when it comes to selling machinery.
Also MTU Series 2000 engines (567–970 kW) for construction equipment, industrial and mining applications will be available with EU Stage V certification from the end of 2022.
