MAN Engines E32 series next generation

MAN Engines is modernizing the tried-and-tested E32 gas engine series for natural gas and biogas applications. Since its market launch in 2012, over 10,000 engines in this series have been installed worldwide. The continuous further development underlines MAN Engines’ claim to continue to set standards in efficiency, emission behaviour and service life in the future.

E32: MAN Engines thinks both to biogas and natural gas

The current product update of the MAN E3262 LE202 (natural gas) and LE212 (biogas) engine types focuses on the revision of the turbochargers. Structural changes have significantly increased its robustness. For example, a dry turbine housing with insulation is now used, which does not require additional water-bearing pipes. This not only reduces potential leaks, but also prevents thermal hotspots in the event of insufficient coolant flow. In addition, new thrust and plain bearings made of a special bronze alloy ensure improved corrosion resistance and longer service life.

The pluses of the new turbocharger

The new turbocharger generation also offers clear economic advantages. Efficiency increases are particularly impressive at a NOₓ limit value of 250 mg/Nm³. This regulatory value for nitrogen oxides is considered the standard in many countries. “The requirements of international markets were clearly the focus of the further development of our systems,” explains Hubert Gossner, Head of Power & Off-Road at MAN Engines. “Particularly in optimizing efficiency, we have taken specific care to consistently take into account the globally applicable emission limits – in particular the 250 mg NOₓ. In this way, we ensure that our solutions are not only high-performance, but also globally operational.”

In addition, a higher pressure reserve via the throttle valve ensures a larger power reserve, which leads to more stable engine performance, especially at increased exhaust gas back pressure or at altitudes.

The V12 platform

The modernized E3262 gas engine is based on the globally proven V12 platform, which has been used for many years as the D2862 diesel engine with a displacement of 24.2 liters in both the marine sector and the E3262 gas engine with a displacement of 25.8 liters in stationary applications for power and heat generation. The engine is available as both turbocharged and naturally aspirated variants, which means that a tailor-made solution can always be implemented for different application profiles – be it electrically or heat-controlled.

The MAN E3262 reliably meets the international emission limits of 250 mg NOₓ/Nm³ within the engine, thus offering a flexible solution for a wide range of market requirements. For particularly emission-critical markets with a limit value of 100 mg NOₓ/Nm³, the engine can be used in combination with an external exhaust gas aftertreatment system – such as an SCR system.

The new engine types E3262 LE272 (natural gas) and LE282 (biogas) replace the previous LE202 and LE212 variants and can be ordered now with delivery from the second half of 2026 at the earliest. The former LE202 and LE212 variants will be available in parallel with the modernized LE272 and LE282 in the medium term.
