Yanmar L-V Series – air-cooled single-cylinder diesel engines of the register: L48V, L70V and L100V from Yanmar's industrial engine production
The Yanmar L-V Series brings together on this collective page three air-cooled single-cylinder diesel engines: L48V, L70V and L100V. The power steps 48, 70 and 100 also appear in the L-N range; L-V and L-N thus form two parallel versions of the same displacement classes within Yanmar's industrial engines. Yanmar was founded in 1912 in Osaka and still builds its air-cooled single-cylinders for stationary and mobile industrial use today.

The register lists here 3 versions: L48V, L70V and L100V. Output ranges from 3.4 to 6.8 kW (4.6 to 9.2 hp) at displacements of 219 to 435 cm³ and a rated speed of 3,600 rpm; all three are air-cooled naturally aspirated single-cylinder engines, dry weight lies between 29.5 and 48.5 kg.
Air-cooled single-cylinder diesels such as the L-V range drive pumps, compressors, small construction machines and agricultural equipment; their independence from a coolant circuit makes them especially suited to regions with unreliable water supply or to winter conditions.
When buying used, what counts on these single-cylinder diesels is the condition of the fuel filter and lift pump, play in the crank train, and the condition of the cooling fins; on permanently built-in engines, removing the attached equipment is often the only way to see the true wear condition. Spare parts run through Yanmar's industrial engine distribution.
