CUMMINS QSK19-R HORIZONTAL ENGINE MEETS THE LATEST STAGE IIIA EMISSIONS
19 September 2006
Berlin, Germany (September 19, 2006) - Cummins latest version of the Stage IIIA/Tier 3 certified QSK19-R horizontal engine for passenger railcars is exhibited at the Innotrans exhibition (September 19 - September 22). By incorporating state-of-the-art modular common rail fuel system (MCRS) and the latest combustion technology, the well-proven 19litre horizontal engine now has even lower emissions whilst retaining its output range of 485 kW to 560 kW (650 hp to 750 hp).
"The engine is purpose-designed for powering high speed rail Diesel Multiple Units (DMUs) and passenger railcars around the world", commented Steve Dodman, Locomotive-Business Development Manager. "The new generation QSK19-R meets the latest Stage IIIA European emissions as well as Tier 3 EPA MOH (Mobile Off-Highway) emissions. The 19litre engine is the number one engine in the European market in the range of 485 kW (650 hp) to 560 kW (750 hp) for the underfloor railcar diesel market".
"The QSK19-R will be equipped with Modular Common Rail Fuel System (MCRS) as early as 2007 which is normally found in the locomotive version of the QSK19-L. The vertical locomotive engine with MCRS is already in rail service in a multi-engine, ultra low emissions switcher in California", Mr Dodman added. MCRS offers incomparable capabilities. It enables precise control of fuel injection to prevent unbalanced fuelling and the uneven pressure between cylinders which contribute to NVH (noise, vibration, harshness). Noise under load and at idle can dramatically be reduced, by up to 7 dB(A). Also, engine idle stability and cold starting are considerably improved.
Over 1,500 Cummins QSK19-R engines have been installed worldwide in high speed passenger trains. In particular, Cummins has supplied more than 550 engines to German train manufacturers. A few of the Cummins QSK19-R powered railcars in Germany include the VT612 built by Bombardier, VT605 built by Siemens-Bombardier and VT614 re-power by DB.
This proves that the 19-litre engine far surpasses any other equivalent engine in terms of durability and uptime availability. Indeed, the upgraded Stage IIIA/Tier 3 QSK19-R engine will move this reputation even further ahead with overall durability increased by up to 30%. The engine offers high acceleration and high speed capability reducing journey times - very important factor to both train operators and passengers.
The QSK19-R's compact size, low profile and in-line configuration allows simple underfloor installation, as well as the benefit of all-external maintenance and good accessibility. Furthermore, the QSK19-R's proven high reliability, long life to overhaul and multiple rebuilds make it a unique product in the underfloor railcar diesel market giving increased confidence to rail operators every time.
The 19-litre engine uses full authority control electronic management system which precisely and continually maintains an optimum balance between load demands, fuel-efficiency and emissions control. Plus, it provides advanced monitoring, diagnostic and prognostic capabilities. The Cummins electronic control system has been proven in railway applications throughout the world from the high altitudes of Tibet to the deserts of Namibia.
The engine electronic module operates at twice the processing speed of the previous system, fully isolated from any detrimental thermal or vibration loadings. Engine sensors, harness and connectors have all been upgraded to rugged, fail-safe designs matching that found on much larger Cummins Quantum locomotive engines.
