Using advanced technology which has been called Amplified Common Rail Fuel Systems, the new DD13 and DD15 provide increased fuel economy and combustion.
Turbo compounding on the DD15 turns wasted exhaust gases into usable energy. This model also features an extremely wide torque band and pulls down to 1100rpm, resulting in less shifting.
MTU Detroit Diesel Australia President and CEO, Doug Seneshen said that the launch of these new engines heralds a new era for MTU Detroit Diesel Australia. He said, ““With these innovative heavy-duty engines offering unparalleled torque response and power, increased fuel economy, low cost in ownership, and a smoother, cleaner ride – they are Detroit Diesel’s most technologically advanced engines yet.”
The DD13 and DD15 have completed rigorous 120 point testing on Australian roads and will hit the roads later in the year.
Since May 2009, the five trial engines have traveled over 1.4 million kilometers, hauling single trailers, as well as, B-doubles and road trains on inter and intrastate routes to ensure they are tested under a wide variety of conditions.
According to MTU Detroit Diesel Australia National Engineering Manager, Guy Macklan, the test results were very positive. He said that the DD13 and DD15 would outperform other engines in the market.
“Using a combination of technologies that have never been put together before, Detroit Diesel has manufactured a lighter, quieter, more efficient engine,” said Mr Macklan. “Feedback from drivers of the test trucks has been fantastic– they’ve travelled from Melbourne to Perth, along the east coast of Australia, through stop-start traffic in cities and in regional areas – and in all conditions the DD13 and DD15 have impressed.
“It’s also been designed with low cost of ownership and ease of maintenance in mind and we’re confident this engine will save our customers money over its life-cycle.”
The DD13 and DD15 engines meet current and future Australian emissions standards using Exhaust Gas Recirculation (EGR) that reduces the space claim on the chassis, eliminates the need for a supplementary fuel tank and has minimal after-treatment systems.
Mr Seneshen added, “MTU Detroit Diesel Australia’s dealer and support network are more comprehensive than ever and are service-ready for both the DD13 and DD15. We are confident that they will dominate all in its class.”
DD13 and DD15 engines will be exclusively available in Western Star and Freightliner chassis.
