Lion Engine Science and Technology – other nonroad diesel engines: the collective page of EPA-certified four-cylinder engines from the Chinese maker outside the named ranges, 20 to 36 kW, Interim Tier 4, 90 mm bore
Lion Engine Science and Technology is a Chinese maker of small diesel engines. This page gathers the nonroad diesel engines from the US EPA certification data that the register could not assign to a named range. The four versions carry the designations LN490DZL, LN490DZL-1, LN490DZL-2 and LN490DZL-3 and share cylinder geometry and engine family.

The register lists here four versions with 20 to 36 kW rated output at 1,800 rpm, from inline four-cylinder engines with a 90 mm bore and 105 mm stroke. Maximum torque ranges from 106.1 to 191 Nm, also at 1,800 rpm. All four engines carry a waste-gate turbocharger and direct injection, rated for diesel with 300 to 500 ppm sulphur content, classed in the 19 to 37 kW power category under the EPA Interim Tier 4 emission stage. "Fed (non CA States)" is recorded throughout as the distribution area, meaning the US outside California.
With 20 to 36 kW and four cylinders, the engines sit in the lower to medium power band of mobile machinery, used in smaller construction machines, compressors and generator sets; the Interim Tier 4 emission stage marks a transitional step in US emissions regulation ahead of full Tier 4 Final.
On a used purchase, operating hours and the service history of the injection system, the condition of the waste-gate turbocharger, the tightness of the charge-air ducting, and the starter and cooling system all count. Spare parts and service run through the Chinese manufacturer and its export partners.
