IN certain instances, where Diesel engine speeds have been taken above 2,000 r.p.m., quite an unexpected degree of trouble has been met with in big‐end bearing design. Bearing areas and connecting‐rod stiffness have been increased in the oil engine, as compared with the petrol engine, so as to allow for the higher gas pressure in the former type, but in spite of this, the white‐metal linings in some engines have been found to break up in the course of long running.
