3.1

Aim of development

The L-series designs are compact, lightweight engines
suitable for superseding gasoline engines to power
lawn mowers, vehicles, etc. The high-speed (3600 min
1
continuous) engines are also available for generators,
welders, and marine use. The L series are the smallest
and the lightest water-cooled diesel engines in the
world.
3.2

Features of the new series

3.2.1 Small and lightweight engine
The new L-series are 10 to 20% lighter in weight and
15 to 20% smaller in contour volume than the same
class of competitor's engines.
3.2.2 Low noise and economical fuel
consumption
Low noise and economical fuel consumption are
attained by the well designed cylinder block
construction (having curved side faces), the rearranged
combustion chambers, and the compacted fuel
injection system.
3.2.3 Easy starting
The engine can be started instantly only by keeping the
starting switch key in the ON position for about 6
seconds to feed electric current to the glow plugs
automatically (For engines with the automatic glow plug
system). The new governor mechanism also
contributes to easy engine start, by increasing the
amount of fuel injection and delaying injection timing,
without moving the throttle lever to the "full throttle"
position.
