WARTSILA RTA—79.1 AND RT—FLEX—08.1 SERVICE BULLETIN — CONTINUOUS LOW LOAD OPERATION

Official service bulletin released by Wartsila and containing necessary technical information to all operators and owners of the RTA/RT-FLEX diesel engines. The content is presented in thee parts. The first one is introductory while the other two parts are dedicated to the considerations and recommendations.

Subject engines have been optimized to operate in the range of loads above approximately sixty percent CMCR. Continuous running of the engine at lower loads is still possible; however, this will influence the engine components and its operational parameters. This manual gives the guidelines for the low-load operation...
