The Yanmar L100N is a compact, air-cooled diesel engine designed for industrial equipment and packaged applications where simplicity, reliability and service access are priorities. It is a 1-cylinder engine with 0.435L displacement and direct injection combustion, delivering up to 7.4 kW at 3600 rpm. The air-cooled layout keeps installation straightforward and reduces cooling-system complexity, which is particularly useful in compact machinery and portable equipment packages.

For OEM builds and replacement projects, using the exact model code L100N is important for matching the correct supply configuration and installation details (mounting, shaft, governed speed requirement and start type). If you share your application and any existing engine plate information, we can confirm the correct configuration and quote the right package.
