Series 4000
The new generation of the Series 4000 engine covers the 1,678 to 1,864 kW (2,250 to 2,500 bhp) power range with a 12-cylinder version and is suitable for driving hydraulic fracturing or “frac” pumps. The engines fulfill the EPA Tier 4 interim emissions regulations using only in-engine technology and no exhaust gas aftertreatment.

Series 2000
The new generation of the Series 2000 engines for oil and gas applications covers the 858 to 1,163 kW (1,150 to 1,560 bhp) power range and is used in various mechanical and generator-drive applications such as in pumps, blenders, drill rigs, fracturing, hydration and nitrogen pump applications. The engines fulfill the EPA Tier 4 interim emissions regulations using only in-engine technology and no exhaust gas aftertreatment.

The new engines for applications in the oil and gas industry meet the new emission targets with even less fuel consumption. Pictured: Assembly of a Series 4000 diesel engine at the MTU plant in Friedrichshafen Download (JPG, 259 KB)
The new engines for applications in the oil and gas industry comply with EPA Tier 4 interim, the current US emissions standard. They do so without the need for exhaust gas aftertreatment, and with even lower fuel consumption than before.

Exhaust gas recirculation (EGR)
In exhaust gas recirculation, some of the exhaust gases are returned to the fresh air intake in the part-load range. The resultant mixture of fresh air and exhaust gas has a lower calorific value in terms of the volume and is thus unable to reach the temperature required in the combustion chamber to produce nitrogen oxide (NOx).
