Exceeding Power And Environmental Expectations – Yanmar Air Cooled Engine

To achieve the highest performing miniaturized and light weight diesel engines, Yanmar developed the L-N series single cylinder, air-single cylinder technologies.

Designed with Yanmar’s proprietary direct injection technology, maximum combustion efficiency is realised through the ideal match between the combustion chamber and injection system. this means that a powerful, but environmentally friendly engine.

Yanmar L-N Series engine are designed to supply power to a wide variety of Driven Machines including

  • Pumps
  • Power Generation
  • Construction
  • Agriculture

Compact, Direct Injection Engine = Easy Installation & Low Fuel Consumption

Keeping with the traditional compact design, L-N series are simple to install. It fits in cramped spaces without sacrificing power and performance. Yanmar’s proprietary direct injection technology allows the engine to sip rather than gorge on fuel. This means lower running cost in the world of rising fuel prices.

Additionally Yanmar developed the miniaturised fuel injection system, one of the world’s smallest. This FIE and direct injection system give you maxium power from every drop of diesel and low fuel consumption

Low Vibration and Low Noise

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

A Little Engine Built to Stand up to Hard Work

The design, structure and materials of the L-N combine to form a rugged, hard working machine. With tough but lightweight alloys used for main engine parts, an extra tough crankshaft and an overall simplified structure the L-N is a compact package of power.

Quick and Easy Start

This is fast, effortlesss starts from a one- pull recoil starter. Starting is a breeze with the standard recoil starter. A short and smooth pull of the toggle kicks off the engine, as simple as a gasoline model.  It is made easy by a special auto-return decompressor and Yanmar’s own efficient combustion system.  Electric starting is available.
