Yanmar 6LY3-STP marine diesel engine 440hp

الوصف

Yanmar Marine has introduced two more engines in its new generation series of electronic control diesels. The new 6LY*-STP is rated at **0HP (**4kW) and the 6LY*-UTP is **0HP (**9kW), both at 3,**0rpm and measured under conditions defined by ISO ***5 conditions.



These latest engines were introduced at Genoa Boat Show, one month after the first in the new line, the **0HP (**3kW) 6LY*-ETP, was shown in public for the first time, at Southampton Boat Show. The completely redesigned, turbocharged, intercooled, wastegated, direct-injection, **-valve, in-line-six 6LY3 series engines have Yanmars new electronic governing system. Exhaust emissions have been reduced significantly.

This new electronic control offers constant power regulation regardless of fuel temperatures up to *0ºC 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.



Information from the electronic control system is shown on a multi-function Yanmar LCD display at the helm. Yanmars display unit, factory pre-set, provides full run-time engine data, including engine speed percentage load, hours, battery voltage, coolant temperature, fuel usage rate, fuel level (by using an optional fuel sensor), plus boost and oil pressures. There are *6 alarm indicators and an active command window is included. The system allows event sequencing as well. The engines weigh just **0 kilos, providing outstanding power-to-weight benefits. Dimensions are those of a **0HP engine, making the 6LY3 series the most compact diesels in their class. Length is 1,**0mm, width **1mm and height **7mm.

A new range of marine transmissions has been developed specifically for these electronic control engines. They can be packaged with these Yanmar by Kanzaki hydraulic KMH series gears, quick and smooth to engage, including an electric trolling feature, and with exceptional torque handling capability. These marine gears are *0% more compact and nearly *0% lighter than the closest competitor.



The 6LY3 series engines displacement is 5.**3 litres. They are fully compliant with EPA Tier 2, SAV/BSO Tier 2 excluding mass emission (for 6LY*-ETP), the 6LY*-STP & 6LY*-UTP models will be certified in due course, RCD and IMO requirements.
