MAN E3268 NATURAL GAS ENGINE

Familiar reliability! Founded on a proven base power unit, MAN Engines has designed a reliable engine in line with the latest technology and extensively tested it in field trials.

Efficient operation: Proven reliability

The MAN E3268 LE242 is based on the E3268 variant with 370 kW_mech, which was introduced in 2013, and has therefore been tried and tested in the field hundreds of times over. The V8 engine is available in a variant optimised for natural gas with a compression ratio of ε 12:1 and can also be used with biogas with a compression ratio of ε 13.6:1. Potential uses in electricity-led CHP (cogeneration) applications range from the industrial and commercial to the municipal and leisure sectors.

Optimised to the application! Flexible use for operation with natural gas or special gas: Specially adapted pistons and turbocharger increase efficiency.

Flexible use

The E3268 LE242 is well-equipped for future emission requirements thanks to a variant with nitrogen oxide levels of 250 mg/Nm³ NO^x (5 % O²). At the same output of 320 kW_mech, the MAN gas engine – equipped only with an oxidation catalyst – meets the requirements of the Technical Instructions on Air Quality Control (TA Luft ½).

For markets with a mains frequency of 60 Hz, MAN Engines also offers an operating variant of the E3268 LE242 for natural gas with 1,800 rpm nominal speed. This delivers 340 kW_mech and achieves a mechanical efficiency rate of 40.3 % and a thermal efficiency rate of 48.2 %, or 88.5 % in total.
