Lombardini Marine, a division of the Lombardini Group, was set up with the objective of preparing and marketing engines for marine applications based on well-esta- blished and reputed FOCS and CHD families. Lombardini Marine is a very modern structure managed by a group of persons highly experienced in the marine engine field and capable of applying to this specific sector the most advanced available technology.

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 dura- bility and low fuel consumption without redu- cing the performance of the engine. Finally, the engines fully conform to the new Particular attention has been paid to sim- plifying the installation and maintenance ope- rations as well as the specific processes that have been applied to the metals to preserve them against the salt corrosion, which place this line of engines among the technologically most advanced...

Robustness, sturdiness and minimum The original design concept as the pearlitic grey cast iron cylinder head with integral re- borable "twin"arranged liners, with cross flow intake and exhaust pipes, has allowed the reduction of the engine lenght assuring at the same time an exceptional sturdiness. The LDW 502 M, which has been built with an alumi- nium engine block and reborable liners is the lightest of the FOCS series. Excellent results have been obtained in redu- cing noise emission thanks to the location of the injection system in the cylinder head, to a ribbing system along all the engine...

The camshaft is located in the upper part of the crankcase to allow a reduced width in the lower area of the engine. The innovative design of the gear train, the injection system design and location, and the reduced cylinder pitch, shorten the engine Operational comfort The special crankshaft balancing gives excep- tional low vibrations and ensures an excellent operational performance during use. Reduction in noise emission The innovative design of the fuel injection system, as well as the utilization of hyper- eutectic pistons which reduce piston slap,and the utilization of a heavy-duty block,...

The shape of the submerged part of drive has been evolved to incorpo- rate an excellent hydrodynamic profile with an extremely low drag coefficient, where the drive's section and chord are reduced to the mini- mum, for optimum boat speeds bet- The axial thrust is handled by a spe- cial conical bearing arrangement. To make the installation easier, the drive has its own built-in sea water inlet and is supplied with a sea cock.
