(a) The efficiency of diesel engines, especially of two-stroke low speed diesels, is almost independent of load over a wide load range. Furthermore, low load running without any limitation is possible down to approximately 20% of maximum continuous rating (MCR), while still ensuring high efficiency and reliability, irrespective of the plant running program.
