A short description is given of the Bergensfjord double-acting two stroke loop-scavenged main engines, which are of the same design as for the m.s. Oslofjord, the only difference between the two engines being the number of cylinders.
Results of test-bed and trial trip are included to show the performance of the engines.
The increasing demand for tanker propulsion units wih ratings of up to 10,000 b.h.p. and over called for a Diesel engine with minimum maintenance requirements and high exhaust temperature for maximum steam production.
Together with the new application of turbo-charging for two-stroke engines, this induced Stork to develop a new single-acting two-stroke engine with uniflow scavenging, specially constructed for the application of turbo-charging by means of exhaust-driven turbo-blowers and adapted for the use of heavy fuel. A description of this engine type is given together with performance curves.
The sound constructional principles which have been responsible for the satisfactory service results and the reliability of the double-acting engine were incorporated in the new design and the service results of this new engine so far have been completely satisfactory.
