LS Mtron – other nonroad diesel engines: the collective page of the L3 range outside the named models, South Korean maker from the LS Group, 22 to 54 kW from three- and four-cylinders, Tier 3 to Tier 4 Final
LS Mtron is a South Korean company within the LS Group, formed in 2005 from the split of the LG conglomerate; the company builds farm machinery, construction-machinery components and its own diesel engines, among others for the group's own LS tractors. This page gathers the engines the register could not assign to a named range; model designations such as L3C19-T5 or L3CRV-T10A combine cylinder count (L3 for three-cylinder, L4 for four-cylinder), a displacement figure (19 for 1.9 litres) and a code for the version, while the EPA engine-family codes such as NLGCL01.9L3C encode displacement in litres and cylinder count a second time.

The register lists here 53 versions with 22 to 54 kW rated output at 2,300 to 2,600 rpm, from three- to four-cylinders with 88 to 90 mm bore and 95 to 105 mm stroke, torques from 102 to 276 Nm. Of the 42 turbocharged versions, all carry a waste-gate turbocharger, so the remainder are naturally aspirated; injection is direct on 48 of the 53 engines, indirect on 5. Among the emission stages, Tier 4 (Final or Phase-in) dominates with 50 ahead of Interim Tier 4 with 3 versions; model years run from 2011 to 2026, and the power categories up to 37 kW and 37 to 56 kW split the field almost evenly.
Engines of this size class drive mini excavators, small wheel loaders, tractors and stationary units; LS Mtron supplies both its own farm- and construction-machinery production and OEM customers in the lower to mid power segment.
On a used purchase, operating hours count, the condition of the turbocharger on the turbocharged versions, the injection system and its injectors or nozzles, the tightness of crankshaft seals and valve cover, and on the Tier 4 Final engines the exhaust aftertreatment; spares run through the LS Mtron dealer network.
