This series of exceptionally light and compact engines, features very high reliability in every condition; furthermore, this specific project has been carried out in order to optimize durability and low fuel consumption without reducing the performance of the engine.
4 stroke marine diesel engines (LDW 502 M, LDW 702 M, LDW 1003 M, LDW 1404 M), fresh water cooled via heat exchanger, complete with zinc anode protection; cast-iron engine block (aluminium for LDW 502 M); reborable liners; one piece aluminium cylinder head; indirect injection with unit injector pump in the cylinder head; overhead camshaft with timing belt; vane type lubrication pump on crankshaft; fresh water cooling pump in the engine block; stainless steel water injected exhaust elbow; self-priming sea water pump; air filter; anti-corrosion surface treatment.
The original design concept as the pearlitic grey cast iron cylinder head with integral reborable “twin” arranged liners, with cross flow intake and exhaust pipes, has allowed the reduction of the engine length assuring at the same time an exceptional sturdiness. The LDW 502 M, which has been built with an aluminium engine block and reborable liners is the lightest of the FOCS series.
