This database lists 545 gas generator engines from 53 manufacturers ranging from 16 kWe to 11,830 kWe, covering gas (natural gas including CNG/LNG, biogas and propane/LPG) power. 448 are marked active in the catalog and 97 are discontinued or archived. Cylinder configurations include V12, L6, V16 and V8. Recorded emissions classifications include Application-dependent, China III (GB20891), China Non-road Stage III / GB20891-2014 and Historical production ended 1944. 449 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 gas generator engines around 16-11,830 kWe, then compare prime, standby and frequency ratings against the actual load profile.

Check site constraints

Review gas 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.

Frequently asked questions

What is the power range of gas generator engines?

Gas generator engines in this database range from approximately 16 kWe to 11,830 kWe of electrical output, across prime and standby ratings at 50 Hz and 60 Hz.

How many gas generator engines are listed?

There are 545 gas generator engines in the database — 448 marked active in the catalog and 97 discontinued or archived.

Which manufacturers make gas generator engines?

Gas generator engines come from 53 manufacturers, including Cummins, Waukesha, Generac, Jichai and PSI.

Are supporting documents available for gas generator engines?

Yes — 449 of the 545 gas generator engines have documents or reference links on their detail page. These may be datasheets, manuals, brochures or reference pages; a link alone does not verify every listed specification.
