Sulzer RTA-62 Diesel Engines Service Bulletin - Prevention of Water Carry-Over and Liner Polishing

   Sulzer RTA-62 Diesel Engines Service Bulletin - Prevention of Water Carry-Over and Liner Polishing. This is the Technical information to all operators and owners of Sulzer RTA engines. Released by Wartsila in 2003.


Sulzer RTA-54 Diesel Engines Service Bulletin - Electronic Variable Injection Timing Troubles and Remedies

   The investigations showed that the VIT positioning unit is moving in and out with each injection under the forces in the fuel injection pumps. This movement could have an amplitude of up to 1.5mm (peak-to-peak) and results in excessive wear on the positioner's feedback transmitter. In order to make the system robust agaiast these small but frequent movements, that have to be accepted and must be considered normal in the present arrangement, a backlash of 2mm (peak-to-peak) has been introduced between the piston rod and the feedback potentiometer. The resulting loss in positioning accuracy is within the acceptable tolerance for the VIT system. In addition the solenoid valves were changed to a rigid design based on experience with sticking valves of the previous design. However, those internal changes are not absolutely essential on all engine types and trouble-free operation of the original VIT has been experienced in many installations.


Sulzer RTA-53 Diesel Engines Service Bulletin - Variable Injection Timing and Fuel Quality Setting

   In the seventies when fuel consumption gained more importance Sulzer introduced the so called Variable Injection Timing and Fuel Quality Setting (VITand FQS) system on its low speed two stroke engines. The VIT and FQS system performs two main tasks. The VIT part is an automatic function that controls the injection begin depending on the actual engine load and cares for optimum part load fuel consumption. The FQS part is a manual adjustment that is meant to be used to match the injection timing to the quality of fuel used. VIT and FQS have been introduced as standard on RTA engines at first in a mechanical and later in an electronic version. The latter is the only standard system for current RTA engines and will be the main subject of this Bulletin. A retarded injection is one of the measures used on Sulzer RTA engines to comply with the International Maritime Organisation (IMO) NOx emission regulations. The applied injection delay depends on engine type and rating and has been introduced in the DENIS-system as a new, load-independent parameter. Therefore the VIT system has gained coasiderable importance with the introduction of the engine tuning complying with the IMO NOx (Oxides of nitrogen) emission regulations on the Sulzer RTA engines. Due to the optimisation character of the VIT function an engine can run both with and without VIT and FQS function without any loss of operability. However, because of its proven beneficial effect on fuel consumption especially at part load it Is advisable to have the VITand FQS system always working during normal engine operation. All RTA engines have been designed for continuous VIT and FQS operation i.e. the use of VIT and FQS keeps the engine parameters well within safe limits. On the latest RTA engine designs complying with the IMO NOx emission regulatioas, the range of FQS adjustment is limited so that NOx emission limits are ensured with any setting of the FQS. This Service Bulletin shall explain the VIT and FQS system in its different design versions and give some general advice on how to check the system and its correct function in order to guarantee maximum availability and thus benefit for the operators.

Sulzer RTA-46 Diesel Engienes Service Bulletin - Cracks in Column

   Occasionally some cases of cracks have been reported on the columns of RTA "-8 Series" and RTA "-2 Series" engines. The present Service Bulletin has been released to inform about the possible location of such cracks in the column and how to apply preventive measures to the respective unit. The RTA "-8 Series" comprises the following engine types in this document: RTA 58, RTA 68, RTA 76 and RTA 84. The RTA "-2 Series" comprises the following engine types in this document: RTA 52, RTA 62, RTA 72 and RTA 84M. Wartsila NSD Switzerland Ltd together with the engine builders concerned have investigated the likely causes for the occurrence of cracks in columns and have looked at the problem from various angles such as design, manufacturing and also operational aspects. Numerous strain gauge measurements were performed as well. During gouging of such cracks often shortcomings were found such as: Incorrect plate edge preparation, Welding root faults; lack of penetration, Small non-penetration on the welding comers; sharp edge corner of cross head guide plate; not ground out according to the drawing or welding and quality specification.

Sulzer RTA-38 and RTA-48 Type Diesel Engines Service Bulleetin - Regulation of Cylinder Liner Lubrication

   Basically, the settings of the cylinder lubrication have to be checked from time to time, mainly to learn whether or not the correct amount of cylinder lubricating oil is used. It is sometimes necessary to make some minor adjustments; this should be done without disturbing the basic settings of the linkage or the mesh between the toothed segment and the gear wheel. Minor adjustments should only be carried out on the adjusting screws of the pumps or by changing the fulcrum by moving the connecting bar one hole up or down on the setting lever. For your convenience, we have listed below the setting and checking procedures of the load-dependent cylinder lubrication...
