The Kingisepp Machine-Building Plant (KMZ), a military-industrial holding, has signed a contract with a foreign customer for the repair of a 15D100 engine based on its technical condition. To verify the engine's performance after the repair, KMZ has its own testing facility consisting of 12 stands of varying power.
15D100 is a complex installation consisting of an engine and a three-phase synchronous generator, which are mounted on a common frame and connected by a semi-rigid coupling. The diesel engine is two-stroke, vertical, ten-cylinder, two-shaft, with opposed pistons, direct fuel injection, straight-flow scavenging, and water cooling.
Each cylinder has two pistons that move in opposite directions. In the upper part of the cylinder liner, there are intake ports through which air enters the cylinder from the scavenging receiver. In the lower part of the liner, there are exhaust ports through which exhaust gases enter the exhaust manifold. In the central part of the cylinder liner, there are two injectors through which fuel is injected into the combustion chamber. The upper and lower crankshafts are connected by a torsional vertical transmission.
The diesel engine is started using compressed air. The diesel generator can be controlled either remotely from remote posts or automatically from an external pulse without the participation of the service personnel. The diesel engine itself has manual control, and no additional switching is required when switching from remote to manual control.
The nominal power of the 15D100 is 1600 kW, the fuel consumption at nominal mode is no more than 250 g/kW*h, and the oil consumption at nominal mode is 4.5 g/kW/*h. This engine is used in most nuclear power plants in Russia as a backup power source. The company does not specify for what purposes the foreign customer uses it for repair work.
