mtu Series 4000
mtu diesel engines provide reliable solutions for all of your marine needs.
More than 20 years ago, in 1996 the first mtu Series 4000 marine engine was presented at SMM exhibition in Hamburg. Since then, the mtu Series 4000 is trusted in numerous applications. With more than 58,000 Series 4000 engines sold worldwide we gained experience from more than 345,000,000 operating hours which were directly fed into the development of the next generation of our marine workhorses.
This is just as true today, as it was in 1996 when we introduced the first high speed diesel engine with common rail fuel injection. Since 2016, we have the only high-speed diesel engine for hard workboat applications with a power output of up to 4300 kW (5780 hp).
Legendary. Since 1996.
Our Series 4000 M05 for commercial marine applications is the latest marine engine of the powerful Series 4000 family. When designing the Series 4000 M05 we kept three topics always in our mind: Life-cycle- costs, perfomance and ease of maintenance.
We used our legendary IRONMEN engines as a basis but finetuned it with high attention to detail to maximize durability, performance and efficiency. Some examples: we changed the alloy of the piston ring to reduce wear. We also relocated fuel filters to grant optimal servicability.
Additionally the air filters are now integrated in the outline of the engine which makes the Series 4000 M05 even more compact. We used advanced simulation of the combustion process to reduce particulate matter inside the engine which makes the need for an additional DPF redundant. Only SCR is needed to fulfill IMO III and EPA Tier 4 emissions regulations.

Low emissions. Maximum flexibility.
As installation space is always restricted inside the engine room, the inhouse developed airless SCR (Selective Catalytic Reduction) solution from mtu is compact and maintenance friendly. Besides easily accessible doors for replacement of the SCR catalysts, the system also features an integrated mixing pipe and dosing units. The integrated mixing pipe and DEF (Diesel Exhaust Fluid) dosing allows the shipyard highly flexible pipework between the engine and the SCR box. Additional space to fit the exhaust gas aftertreatment is reduced to a bare minimum. Amonia slip is prevented under all operating conditions by a closed loop regulated control system.
When using EGR (Exhaust Gas Recirculation) technology, the quality of the fuel is essential. Fuel with more than 15 ppm sulfur will lead to the formation of sulfur acid in the EGR cooling process. Sulfur acid will cause substantial engine failures over time. As many vessels operate worldwide, especially in the offshore service and supply business, mtu evaluates SCR as the preferred solution to maintain reliability of our engines and the safety of your vessel and crew. SCR technology allows operation with lower fuel quality.

Encapsulation and Mounting
Sound encapsulation and engine mountings for marine engines involves the strategic implementation of soundproofing materials and design modifications to reduce noise emissions from the engine compartment. This process aims to contain the noise at its source, preventing it from escaping and propagating through the water and surrounding environment. Depending on the application different targets can be achieved such as raised passenger comfort in yachts to enhanced tactical advantages for frigates based on the lower noise levels. mtu engines can optional be equipped with enhanced mounting and sound encapsulation technologies and contracted sound levels via our internal engineering experts.
Propulsion solutions
We are a leader in the field of propulsion systems with low magnetic and acoustic signatures, allowing us to reduce the magnetism of all ferromagnetic parts with our own method to a stable minimum.
