3 Introduction Certain spare parts for the two-stroke engine are considered to be Essential Wear Parts as they are key components that have a critical effect on the performance of the engine. Our continuous development and focus help us provide our customers with the best possible product and service every time. We have a sharp focus on this group of components which share a number of commonalities, the overall being a long lifetime. mainly include large components, and not standard wear parts such as O-rings, which means that they represent a larger investment. The lifetime is related to the quality of the components, and the high quality of the parts from MAN PrimeServ ensures an optimal lifetime. Features of : - Key components critical for the performance of the engine - Long lifetime - Increased focus internally - Mainly large components - Large investment. 3

Cylinder Liners The size and design of this Essential Wear Part requires a high level of technological know-how and experience within engineering and manufacturing of these complex components.

4 Cylinder Liners The size and design of this Essential Wear Part requires a high level of technological know-how and experience within engineering and manufacturing of these complex components. MAN Diesel & Turbo has both the know-how and the experience and is therefore able to produce our cylinder liners in a high quality. The design of our liners is based on many years of service experience and is under continuous development. The above combination as well as having the world s leading and most experienced cylinder liner supplier, ensures the highest quality of the products. MAN Diesel & Turbo has been designing engines for more than 100 years, and our desire to provide the best products ensures that the development and optimisation never stops. This is reflected in our entire product portfolio including the cylinder liners. Features of the cylinder liners The standard liner surface has a semi-honed profile that ensures good oil retaining properties, as oil is accumulated between the plateaus thereby ensuring a hydro-dynamic oil film. Benefits Latest design updates Reliability Know-how of the engine designer Extended warranty = 36 months. 4

5 Piston Crowns This Essential Wear Part must be of high quality and precision, as it is vital for the reliable operation of the engine. This is why all sub-suppliers of MAN Diesel & Turbo piston crowns must demonstrate their ability to fulfil all the requirements stated in the quality control agreements before they can be approved as producers and suppliers. These agreements also contain CSR (corporate social responsibility) requirements, as MAN Diesel & Turbo considers this an important matter when doing business. Features of the piston crown The piston crown is the top part of the piston which transmits the pressure created during the ignition of the air-fuel mixture to the crosshead, on to the connecting rod and from there to the crankshaft. In other words, it is an essential part of transforming the combustion-energy into mechanical energy. Furthermore, the piston crown is exposed to a very harsh environment with high temperatures and pressures. This is why the design includes special features that requires the most advanced manufacturing technology to achieve the high standard we offer. Benefits High quality All suppliers/manufacturers must fulfil quality control agreements Focus on CSR Extended warranty = 36 months. 5

fulfilled. This is done by using our in-house expert knowledge on precision machinery. Worldwide focus and demand is on reducing fuel oil consumption and emissions.

6 Spindle Guides Slide Valves Fuel equipment requires extra focus and the spindle guide is therefore an Essential Wear Part. Many of our fuel equipment components, and components which have an influence on the engine emissions, are manufactured in-house in Copenhagen to ensure that our high production requirements are fulfilled. This is done by using our in-house expert knowledge on precision machinery. Worldwide focus and demand is on reducing fuel oil consumption and emissions. Therefore, the development and optimisation of the spindle guide and nozzle has a high priority in our R&D department, where beneficial features are continuously developed and tested. Features of the Spindle Guides Slide Valves The spindle guide and nozzle are the main wear parts of the fuel valve, and they need to be changed at certain intervals to ensure a good performance. The combination of the spindle guide and HIP (Hot Isostatic Pressing) compound nozzle ensures a TBO of running hours, thereby keeping the maintenance budget at a minimum. Benefits Latest design Own production in Copenhagen on precision machinery No dripping from the nozzle = cleaner component Cleaner exhaust gas ways. 6

This is also the reason why it is manufactured in-house in Copenhagen to ensure that our high production requirements are fulfilled.

7 Plunger-and-Barrels This Essential Wear Part is included in the IMO technical file because it is essential to the running of the engine. The reason is that the plunger-and-barrel assembly is among the fuel equipment that influence engine emissions. This is also the reason why it is manufactured in-house in Copenhagen to ensure that our high production requirements are fulfilled. When buying a plunger-and-barrel assembly from MAN PrimeServ, we make sure to match the right component with your engine and ensure compliance with the technical file. Benefits Receive the right component for your engine Own production in Copenhagen on precision machinery Latest design Amendments to the IMO technical file free of charge (if required). Features of the plunger-and-barrel The function of the plunger-and-barrel assembly is to deliver the correct amount of fuel oil to the fuel valves for injection into the combustion chamber. Thus, it is important to apply the correct plunger-and-barrel assembly to ensure an optimal combustion process. This is always the case when buying the components from MAN PrimeServ. 7

MAN FIVA Valves The FIVA (fuel injection, valve actuation) valve is essential to the running of the ME engine as it controls the fuel injection and the exhaust valve actuation.

8 MAN FIVA Valves The FIVA (fuel injection, valve actuation) valve is essential to the running of the ME engine as it controls the fuel injection and the exhaust valve actuation. This is the reason why the MAN FIVA Valve is considered an Essential Wear Part. It is the latest in-house component developed, designed and manufactured in Copenhagen. Optimisation is in focus and its development is ongoing. This ensures that we always deliver the best possible product. As an alternative to buying new MAN FIVA Valves, PrimeServ Copenhagen also offers reconditioned units from our production facility in Copenhagen. These valves are reconditioned to their original design and quality but at a lower cost. Features of the MAN FIVA Valves It is a high precision unit that controls the fuel injection and exhaust valve opening of the ME engine and thereby serves the same function as the camshaft on conventional engines. Benefits Latest technology and design High quality Own production in Copenhagen on precision machinery Full reconditioning/exchange programme. 8

Bearings Shells Over the past century, development has moved in the direction of getting a more efficient engine output with a more compact engine design.

Optimisation and development is therefore an ongoing process in order for us to ensure the best possible engine performance.

9 Bearings Shells Over the past century, development has moved in the direction of getting a more efficient engine output with a more compact engine design. such as bearing shells must be adapted to these new requirements and be designed accordingly. Optimisation and development is therefore an ongoing process in order for us to ensure the best possible engine performance. It is vital that the bearing shells can withstand the different loads and wear processes that they are exposed to. Our focus is on increasing the reliability of these products by continuous research. MAN Diesel & Turbo is a designer of two-stroke engines, and we strive to minimise the differentiation between each engine type and, thereby, ensure a higher availability. Features of the bearing shells Thick shell has flex edge Thin shell has blended edge. These features have following positive effects: Ensures equal pressure distribution Increases oil film thickness. Benefits Increased reliability compared to previous designs High availability Thoroughly tested bearing shells High quality. We test various products on seagoing vessels before introducing them to our customers. This means that our bearing shells are more reliable compared to previous designs. 9
