World leaders in compact diesel engines

Yanmar has been at the forefront of design and production for small compact air-cooled diesel engines. The total production of these engines has now exceeded 1.5 million engines since the start of production back in 1959.

Yanmar’s current ‘L Series’ engines are designed and produced specifically for different markets around the world. Their engines range in power from 2.6 kW up to 14.7 kW and continue to power stationary and off-highway equipment worldwide.

The L-N series of engines are designed specifically for the Southeast Asia, Middle East and Africa markets where emissions are not considered for these engines.

The L-V series of engines are fully EURO STAGE V approved specifically for the UK and European markets. These are also a great choice for Japan and surrounding areas.

The L-W engines has been designed and approved to EPA Tier IV Final to fully comply with the USA markets and legislation.

Exceeding Power and Environmental Expectations

Designed with Yanmars proprietary direct injection technology, maximum combustion efficiency is achieved through an ideal match between the combustion chamber and injection system. This means a powerful, yet environmentally friendly engine.

Low Vibration and Noise

Superior vibration and noise reduction is achieved through the use of precision balancers, which leads to operating comfort even during long work hours.
