Volvo Penta Marine Diesel
Volvo Penta has introduced a new line of D11 marine diesel engines. Available in three power classes, 625, 670 and 725 hp, the engines provide more torque, improved drivability and reduced noise levels compared to other engines in its horsepower classes, said the company, while meeting EU Recreational Craft Directive (RCD) and U.S. EPA Tier 3 emissions regulations.
Technical upgrades in the in-line, six-cylinder D11 engines include an enhanced twin-entry turbo, “where each exhaust pulse maximizes charging pressure,” said Thomas Lantz, chief product manager, Volvo Penta. “This gives an extremely powerful torque already at low rpm. The engine responds instantly to operator commands and provides improved drivability with stronger acceleration.”
The engines use the latest generation of the Volvo Penta Electronic Vessel Control (EVC) platform for increased security and control, and improved functionality, said the company.
All engines in the series have the same installation dimensions as before. The fuel and oil filters, oil dipstick and oil filler are at the back of the engine where they are accessible for servicing. The same engine specification can be used for port and starboard installations.
The D11 engine will be available for traditional inboard installations as well as the Volvo Penta IPS (Inboard Performance System) pod drive system. The IPS800 and IPS950 propulsion systems were also launched, and use D11 diesel engines.
