Yanmar L-Series Brochure

AIR-COOLED DIESEL ENGINES

L-N / L-V / L-W Series 3.1 kW / 4.15 hp - 6.6 kW / 8.85 hp

COMPACT, DIRECT INJECTION ENGINE = EASY INSTALLATION & LOW FUEL CONSUMPTION Keeping with the traditional compact design, the L series engines are simple to install by fitting into cramped spaces without sacrificing power and performance. YANMAR’s proprietary direct injection technology allows the engine to sip rather than gorge on fuel, which means lower running costs in the world of rising fuel prices.

Exceeding Power & Environmental Expectations

Designed with YANMAR’s 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.

QUICK, EASY STARTING WITH STANDARD RECOIL

A special auto-return decompresser and YANMAR’s own efficient combustion system breeze through starting with electric starting also offered as an option. 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. THE TOTAL FIE EXPERTISE ONLY A COMPLETE DIESEL ENGINE MANUFACTURER CAN PROVIDE YANMAR developed one of the world’s smallest fuel injection systems. We have since raised it to a level of efficiency that ensures maximum power from every drop of diesel. Its extraordinarily low fuel consumption is a result of our super-precise FIE, and our direct injection system, the first to ever go into this type of engine.
