Improvements in Type 16Д49 Diesel Engines Powering Type 1ДДА12000 Two-Engine Propulsion Unit Used in Series 20380 Corvette
Presented are the results of Kolomna Works project targeted at designing and improvement of medium-speed marine diesel engines type 16Д49 powering two-engine propulsion unit type 1ДДА 12000. In particular, the research included identification of a cause of smoky exhaust of engine (driving fixed pitch propeller through a gearbox) during transients. Smoke in exhaust was mitigated through use of low-inertia turbocharge systems, grouping of exhaust manifolds into individual sections, and optimization of engine loading ramp rate.
