Yanmar L-Series Engine

A Sustainable Future ​

This small industrial diesel engine may have compact dimensions on the outside, but there is clever stuff going on inside. Available in two options, the L70N5 and L70N6, the difference is in the performance characteristics. The L70N5 reaches peak power at around 3000 RPM and the L70N6 peaks higher at 3600 RPM. Also the L70N6 has a much flatter torque curve, peaking at 18 Nm up to 2400 RPM, and offering nearly 14 Nm even at 3600 RPM. This means whatever industrial use you have in mind, you can choose an engine perfectly suited to your speed requirements.
