MAN Diesel & Turbo The responsible way in leading technology
MAN Diesel & Turbo is the world’s leading designer and manufacturer of low and medium speed engines. Our involvement with electrical power generators goes back to 1904 when we supplied the first ever diesel generator sets to the Kiev Tram System. Since those early days, MAN Diesel & Turbo has never lost its technological preeminence in the large engine field. Likewise, our engines have never relinquished their status as the most efficient combustion engines available. More than ever before, MAN Diesel & Turbo’s development focus is on the environmental performance of our engines. Using our unrivalled grasp of large engine technology, we aim to make our engines progressively cleaner, more powerful and more efficient. With our absolute commitment to reducing emissions while increasing fuel effi ciency and power density and, with our active partnership in the emissions law making process, we intend to be part of the global emissions solution.
