Discovery Energy – other nonroad diesel engines: the collective page of small diesel generator-set engines outside the named ranges, 4 to 50 kW from one- to four-cylinders, Tier 2 to Tier 4 Final
Discovery Energy appears in the US EPA certification data as a distribution and certification brand for small-displacement diesel engines, chiefly for generator sets; the model designations on this page such as 11LD625, 9LD625 or KD 350 echo the naming of the classic Italian LD and KD engine ranges in their nomenclature, though the exact manufacturer attribution cannot be reliably established from the data at hand. This page gathers the engines the register could not assign to a named range, with speed variants such as "2400 RPM", "2600 RPM" and "3000 RPM" in the model name, pointing to different mains-frequency or application versions of the same base engine.

The register lists here 197 versions with 4 to 50 kW rated output at 1,500 to 4,300 rpm, from one- to four-cylinders with 75 to 95 mm bore and 66 to 102 mm stroke, torques from 10 to 300 Nm. Indirect injection prevails with around 146 against 51 direct-injection versions; among the emission stages Tier 4 (Final or Phase-in) leads with 114 ahead of Interim Tier 4 with 80 and a handful of Tier 2 engines.
Engines of this class and power range chiefly drive portable and stationary diesel generator sets, plus pumps and small construction compressors; the wide speed band up to 4,300 rpm is typical of air-cooled small diesels in generator applications.
On a used purchase, on these predominantly air- or oil-cooled small engines oil level and oil consumption count, the glow-plug system and cold-start behaviour, anti-vibration mounts and the condition of the exhaust system, and on generator sets the condition of the flanged alternator; given the rather niche nature of this brand, parts supply is worth clarifying in advance, as no wide dealer network is known.

What to check before buying
- Match the data plate against the order: frame size, mounting and rating have to agree.
- For used units, ask about winding condition and bearing play.
- Ask about parts availability for this series — the running costs hang on it.
