Overview
Caterpillar Motoren designed the M 34 DF based on the reliable M 32 C engine series. It will be capable of operating on multiple fuels without sacrificing the typical MaK marine engine attributes. The M 34 DF will be capable of running on Liquid Natural Gas (LNG) as an alternative to the expensive low sulfur Marine Diesel Oil (MDO) or large and complex scrubber installations for ECA operation as of 2015. High efficiency and proven reliability make the M 34 DF an excellent generator set. Due to selected operation profiles and low diesel fuel costs, the M 34 DF is a preferred generator set regarding cost of operation.
