MAN Engines
Optimum performance from just 12 cylinders.
By fine-tuning the inlet and outlet guide vane units (diffuser and nozzle ring), the turbocharger can be operated at the compressor and turbine’s exact optimum efficiency. This reduces the charge cycle work.
They are specially adapted for the combustion chamber. In the newly designed combustion chamber, ignition of the gas now occurs at several locations. This has a positive impact by accelerating combustion. In addition, there are further improvements to combustion stability during low-NOx operation.
Rather unusual for stationary engines, but with a major positive impact on efficiency
With their trough-like geometry, they help to accelerate combustion and thus increase efficiency.

Last updated: 12/03/2024. Since our products are in continuous devlopment, we reserve the right to make technical modifications.
A version for markets requiring speeds of 1,800 rpm (60 Hz) is also planned. As part of the process of converting our stationary natural gas engine range to “hydrogen readiness”, the new MAN E3872 will be designed to accommodate a hydrogen (H2) admixture when operated with natural gas.
