Yanmar 6LY3-ETP marine diesel engine 380hp
Yanmar Marine has introduced two more engines in its new generation series of electronic control diesels. The new 6LY3-STP is rated at 440HP (324kW) and the 6LY3-UTP is 380HP (279kW), both at 3,300rpm and measured under conditions defined by ISO 8665 conditions.
These latest engines were introduced at Genoa Boat Show, one month after the first in the new line, the 480HP (353kW) 6LY3-ETP, was shown in public for the first time, at Southampton Boat Show. The completely redesigned, turbocharged, intercooled, wastegated, direct-injection, 24-valve, in-line-six 6LY3 series engines have Yanmar’s new electronic governing system. Exhaust emissions have been reduced significantly.
This new electronic control offers constant power regulation – regardless of fuel temperatures up to 50ºC – and synchronises the engine speeds of twin installations. Yanmar is working on triple-installation synchronisation. The electronic control manages the fuel delivery and injection timing of the high-pressure fuel pump, resulting in more torque and improved fuel economy.
