Yanmar has newly developed a diesel engine for auxiliary marine use
"EY26L" to make our SAVETEN's lineup more impressive.
In 1998, Yanmar succeeded in the development of the unique SAVETEN
technology (ASSIGN combustion system, Japan patent: 1997-094056,
international patent: PCT/JP98/04502).
To save energy and to reduce NOx are conflicting factor for engines.
Yanmar developed SAVETEN specially the "EY26L" based on the
concept, "harmony with environment" and "to meet client's
needs", which should be reflected in lower running cost and easier
maintenance. By incorporating the new technology, SAVETEN technology, Yanmar
completed an environmentally sensitive and economical diesel engine, which
we are confident of satisfying customer's requirements.
"EY26L" will be launched for auxiliary marine use first and we
plan to commercialize it as a marine main engine and power station engine as
well.
1. Features
- Our unique ASSIGN combustion system that applies the staggered layout
nozzle and efficient airflow system which achieves both lower fuel
consumption and lower NOx emissions.
- Application of new supercharging system decreases pressure resistance
of suction and exhaust to lower fuel consumption.
- The structure of piston ring has been changed from four-ring to
three-ring structure. Furthermore, the method to cool entire cylinder
liner has been changed to cooling only the upper part of the liner. By
implementing these changes, sliding loss has been decreased and higher
efficiency has been achieved.
- Couplings are located in the front side of engine so that the working
of the installing and maintaining is made easier.
- Strength and rigidity of the main parts are improved, and parts and
overhaul interval lifetimes are now longer. The maintenance interval has
been prolonged to approximately 16,000 hours and the number of parts has
been decreased by 40% compared to the conventional engine.
