YANMAR LV SERIES ENGINE
FEATURES AND
APPLICATIONS

To achieve the highest performing miniaturized
and light-weight diesel engines, Yanmar Co., Ltd.
developed the LV series single cylinder, air-
cooled, diesel engine using the most advanced
single cylinder technologies.

Yanmar has incorporated Exhaust Gas
Recirculation (EGR) technology to meet the
stringent exhaust emissions demands required by
the Environmental Protection Agency (EPA - US
Federal) and the California Air Resources Board
(ARB, California). In addition, the pump / line /
nozzle direct-injection system has been
optimized to reduce emissions.

Yanmar LV Series engines are designed to supply
power to a wide variety of driven machines
including:

• Pumps
• Power Generation
• Construction
• Agriculture

We are sure that you will agree these features
provide excellent value in an industrial diesel
engine.

These engines are designed to deliver power to
driven machines by means of a “direct coupled
drive” or “belt drive.” In direct coupled drive
engine applications, the engine’s flywheel
housing or end plate is coupled directly to the
driven machine. In belt drive engine applications,
a belt drive is used to power the driven machine.

The engine is designed for a wide range of
applications. Options are available to customize
the application.

Since designing the application and installing the
engine require special knowledge and skill,
always consult your authorized Yanmar industrial
engine dealer or distributor for these services.
They will help you:

• Select optional equipment. Optional equipment

should be selected to match the work
conditions and environment.

• Maximize engine performance with a minimum

amount of downtime and safety related
incidents by carefully matching the
characteristics of the engine with the driven
machine.

• Plan for safe fuel piping, exhaust piping,

electrical wiring, ventilation and accurate
engine installation.

• Design your applications so they meet

requirements of the local authorities.
