The first thing you notice about
the New YEG
series is that there is so little noise. Yanmar's own CAE techniques
have gauged the stiffness of materials just right and damped radiant
noise. Those methods have also produced the perfect muffler volumes
and optimum use of sound isolation materials. It all adds up to
extra-low noise that is ideal for use in urban and residential
areas.
The all-round people-friendliness is obvious
in the exhaust data, too, thanks to the Yanmar TNV engines.
The New YEG series satisfies EPA Tier 2. It features even
better flow mixing in the main chamber and the special mouth
around the injector, plus efficient use of incoming air for
cleaner burning and low emissions. The New YEG series gives
the air and fuel charging more fluid energy. The swirl continues
better mixing and lower emissions.The New YEG series is kind to the
environment. Beside low noise and emissions, it contains no
asbestos, mercury, polybrominated biphenyl, polybrominated
biphenyl ether or cadmium. The use of safe materials was a
core theme from the word go.

Yanmar has a long tradition of producing world class small, high-speed,hard-working engines. Their combination here with superb 3-phase, 4-wire generators, tried and tested across Asia and the Middle East, brings substantially bigger generation capacity for the same package size. The sound proofed bonnet is lightweight and takes up very little space. The TNV are Yanmar's state-of-the-art small industrial engines, now even more durable than ever due to enhanced block cooling, stiffer cranks and pistons, and finer journal and other tolerance. The gensets have protective devices against lubrication oil pressure drop, excessive water temperature rise and faulty battery charging. These are gensets that will continue to run and run.
Yanmar has developed a remarkable new
shape for the air flow of the combustion chamber through
a rigorous process of experimentation and analysis. It achieves
great mixing of fuel with air that maximizes air use and
minimizes fuel consumption. The combination of low fuel consumption
engines with high-efficiency power generation makes these
quality gensets remarkably cheap to run.
The convenience extends to every aspect of use and maintenance.
You can put the light and compact New YEG almost anywhere
without special foundation work, and all components are
mounted on the single bed. Specially designed anti-vibration
blocks establish even smoother running. The various filters
and battery are located on the same side as the instrument
panel for straightforward daily inspection and handling.
The big fuel tank is good for over 12 hours' continuous
use at 70% load for YEG 170, 230 and 450, and good for
10 hours foe YEG650 and 750.
In fact, all engine, generator and power functions are operated
from a single location, and the control panel is big, high
up and easy to see! The New YEG is a dream series for sureness
and simplicity of use.
Full attention is given to the fine details of safety and dependability that count for so much. The output terminals are covered and placed well way from the instrument panel to prevent electric shocks etc. An earth terminal is included. All rotating parts are well covered, too, for accident-free operation. The use of damper coils in the brushless, AVR generation increases reliability still further by equalizing wave distortion.
