If you are looking for a silent, compact, power source, with minimum fluctuations, the new YDG is waiting for you. Durability and long operation are designed in. Mobility approaches that of a gasoline generator. And the direct injection air - cooled diesels, the amongst smallest in the world, offer very good fuel savings. The power is high. The cost is low. Specifications and accessories are available for most markets. Listen carefully, or you might not even notice they're at work.
An AVR (Automatic Voltage Regulator) gives low-fluctuation power delivery at a selection of voltages from 110V to 240V. Each model also makes available 12V D.C.-really useful for charging car/boat batteries. (excluding 3-phase models)
A single tankful of diesel will keep these air-cooled gensets on the go for 6~15 hours. The secret to such long operation is their low fuel consumption from features like direct injection ?a major feat for this type of compact engine. These genesets give savings with every tankful of diesel. And they have a utility-size fuel tank, so you can leave them running all night.
The extra-lightweight YDG is as easy to move around as most gasoline units. And its easy to store too. We've achieved it by linking together our small air-cooled diesel (the Yanmar L-A type) with a highly compact and light U-frame generator. The size and weight trimming allows you to take these ‘open-type' sets anywhere.
Engine and generator rest on inclined rubber blocks. This improved mounting system takes away both vertical and horizontal vibrations, leaving you with a smoothly purring engine. Noise prevention measures are taken at several levels; at intake, in the combustion system and through the well muffled exhaust system.
The chance of damage due to low oil level operation is reduced with a Yanmar genset. An alarm is activated and the engine stops as soon as the oil falls low. Besides, the sockets on the control panel are recessed and the muffler is enclosed with a cover.
With a short 70cm stroke of a recoil starter, the engine jumps into life. Auto-return decompression makes starling easier and quick even when the temperature is low.
Fewer parts mean fewer maintenance worries-inspection is easy and adjustments simple. Forced lubrication feeds oil to vital parts, and high quality materials give first-class durability
AIR-COOLED DIESEL ENGINE L-A SEIRIES
Its secret is Yanmar's micro-sized
fuel injection system
The fuel injection system, the
heart of a diesel,
has been refined through years of research and
development at Yanmar. We have now
succeeded in minimizing the weight and size of
this equipment and simplifying its structure by
adoption of a bushless pump and a smaller
nozzle.
● Durable-because it built by a specialist in
large diesel technology.
● Convenient Recoil starter-a feature commonly
associated with gasoline engines.
● Fuel costs dip to a new low with Yanmar ' s
direct fuel injection system.
● Very low vibration and quiet running make it
ideal, a popular choice for constantly
operating machinery
