CRM: pure energyPoly-fuel engine with alternative feeding withvegetable fuels from renewable sources
Flying on the water
DESIGN• V or W engine configuration aeronautical type• Arrangement with multiples blocks of in-line 6 cylinder• Optimized balance due to high cylinder numbers • Conrod system with master and articulates rods
MATERIALS• Cylinder head and crankcase in aluminium alloy• Crankshaft and conrods in high tensile strength steel• Extensive use of special treatments to increase fatigue resistance• Low magnetic signature
THERMODYNAMIC• Indirect injection with mechanical pump or Common Rail system• Low compression ratio• Supercharged and intercooled engine, with one turbocharger for each bank
QUALITY ASSURANCE• Quality system UNI EN ISO 9001: 2008 certified by R.I.N.A.
