The Tognum Group will be showcasing its new-generation, MTU-branded US EPA Tier 4i-compliant Series 2000 and Series 4000 diesel engines for oil and gas applications at OTC, the offshore industry trade show taking place May 2-5, 2011 in Houston, Texas. Both engines meet Tier 4i emission requirements through the use of in-engine technology, without aftertreatment.

While no additional details were provided on the engine technology, MTU said that the Tier 4i engines lay the foundations for meeting the Tier 4 final requirements. The company’s goal is to find an in-engine solution to also meet the Tier 4 final standards which will apply from 2015.

The new Series 2000 engines for oil and gas applications cover the 858 to 1,163 kW (1,150 to 1,560 hp) power range. Typical applications include pumps, blenders, drill rigs, fracturing, hydration and nitrogen pump applications. Series 2000 engines consume up to 10% less fuel than their predecessors, according to MTU. Their performance is constant up to heights of 3,100 m (10,170 ft). Series 2000 engines will be introduced onto the market in stages from mid-2011 as 12- and 16-cylinder units.

The new Series 4000 engines cover the 1,678 to 1,864 kW (2,250 to 2,500 hp) power range with a 12-cylinder version. They are suitable for driving hydraulic fracturing or “frac” pumps that inject special fluids under high pressure to fracture rocks to increase the volume and improve the efficiency in the recovery of petroleum and natural gas reserves. Series 4000 engines are weight optimized, allowing mobile “frac fleets”—truck-mounted pump units for the oil and gas production—to stay within the maximum weight limits for highway transit. The engines consume up to 5% less fuel and provide superior torque performance compared to their predecessors. Their performance remains constant up to heights of around 4,000 meters (13,120 ft) without derate.
