(EnergyAsia, June 16 2011, Thursday) — Tognum Group Brand MTU recently showcased its new generation of MTU Series 2000 and 4000 engines in Asia for use in the oil and gas industry.

The Series 4000 engine on display at the Oil and Gas Asia in Kuala Lumpur, Malaysia complies with US EPA Tier 4 interim, the current US emissions standard. This is done without the need for exhaust gas after treatment, and with even lower fuel consumption than before. The new generation engines also provide the basis for MTU’s current development work on engine compliance with Tier 4 final, the even tighter emissions regulations to apply in the US from 2015.

MTU also provides an in-engine solution. The new-generation engines satisfying the Tier 4 interim stage are to be introduced gradually onto the market in the second half of 2011.

“The market for oil and gas applications has huge growth potential and the launching of our new engines will swiftly strengthen our market position in Asia,” said Peter Kneipp, Tognum COO with responsibility for the business unit engines.

“What sets our drive systems apart is the fact that they are both low on fuel consumption and low on emissions, which brings down life-cycle costs overall. That achievement again puts us at the forefront of technological progress,” he added.

The new-generation Series 2000 engines cover the 858 to 1,163 kW output range and are suitable for powering pumps, mixers and drilling rigs. They consume up to ten percent less fuel than their predecessors, although the current emissions stage they have to satisfy is much more demanding. Their combination of fuel efficiency and longer maintenance intervals for specific components reduces life-cycle costs significantly.

The new Series 4000 engine generation is built for a higher output of 1,678 to 1,864 kW and is primarily used for powering mobile hydraulic fracturing rigs. These are pumps which use a special fluid to fracture rock layers under high pressure so that natural gas and crude oil reserves can be tapped in greater quantities and more economically.

The new Series 4000 engines consume up to five percent less fuel than the previous generation and provide a bigger torque range at low speeds with an optimum power-to-weight ratio.
