VOLVO PENTA INBOARD DIESEL enhanced yacht comfort The new generation Volvo Penta D2 series is designed to meet the most stringent environmen- Further reduced sound level and low cruising rpm gives quiet 115A alternator with a built-in charging sensor provides rapid charging for onboard electrical The base engine is developed for industrial applications and marinized for the highest marine demands. This guarantees a reliable engine with a long service life. Smooth running with very low vibra- tion levels is achieved through a dynamically balanced design incor- porating a flywheel of high rotating mass and high efficiency rubber The new engine with re-designed combustion chambers and lower en- gether with the new inlet air silencer gives the highest comfort on board. The noise is further reduced by up to 3 dBA from an already low level. The engine's high torque provides excellent operating characteristics to fined spaces. tion and NMEA interface for present- ing engine data on chart plotters. world's most stringent emission legis- lation - US EPA Tier 3.
