About diesel generator engines

Models: 4,200
Power range: 3–10,126 kWe
Fuel: Diesel
Brands: 76
With documents / references: 2,904

This database lists 4,200 diesel generator engines from 76 manufacturers ranging from 3 kWe to 10,126 kWe, covering diesel power. 2,796 are marked active in the catalog and 1,404 are discontinued or archived. Cylinder configurations include L6, L4, V12 and V16. Recorded emissions classifications include 2g NOx TA Luft, 2g TA Luft, 4g TA Luft and Application-dependent. 2,904 models have supporting documents or reference links. Check each link’s type and scope on the model page. The electrical range combines recorded duty and frequency ratings; it excludes models with only mechanical shaft-power data. Compare matching duty and frequency on the model pages.

Selection notes for buyers

Start with duty and output

Shortlist diesel generator engines around 3-10,126 kWe, then compare prime, standby and frequency ratings against the actual load profile.

Check site constraints

Review diesel availability, cooling package, emissions rules and service support before treating two similar kWe ratings as interchangeable.

Match the alternator and package

After the engine shortlist is clear, confirm voltage, frequency, alternator frame size and radiator or canopy requirements for the complete generator set.

Use this shortlist in a generator-set project

The model list is a specification starting point. Haifeng Machinery can help confirm the engine rating, alternator match, cooling system and emissions requirement for standby, prime or continuous-duty projects.
