MaK has been a marine engine manufacturer since 1922, a rich production history in northern Germany. Since Caterpillar acquired MaK in 1997, the Kiel facility has become a center for research and development for large diesel MaK engines, as well as large diesel and gas engines manufactured under the Cat trademark.

The Kiel Engine Center is responsible for machining, assembling, testing, painting and shipping the MaK M 20 C, M 25 and M 32 C inline marine engines.  In fact, the engine blocks, valves, heads and connecting rods are all manufactured directly on the facility grounds.  Today, the facility is 68,200 m2 (735,000 ft2) and there are plans to expand production further in the future.

To meet market expectations, the Kiel Engine Center has received a massive investment in parts production, assembly lines, test cells and employee training – ensuring that the facility is well-prepared to serve future demands.
