PSI Generator Engines
47 engines in the database
This database lists 47 PSI generator engines ranging from 20 kWe to 3,300 kWe, covering both diesel and gas (natural gas including CNG/LNG, biogas and propane/LPG) power. 45 are current production models and 2 are discontinued or archived. Cylinder configurations include L6, V8, V12 and V16. Emissions certifications span U.S. EPA Stationary and U.S. EPA Tier 3. 47 models link to an official manufacturer datasheet or manual.
PSI repair parts by engine model
These engine pages include reviewed part references. Match the model on your nameplate, then check the serial number and configuration requirements before ordering.
PSI generator engine selection guide
Use this PSI hub to shortlist generator engines by electrical output, fuel type, emissions standard, datasheet coverage, and 50 Hz or 60 Hz rating. For a complete generator set, the engine choice should be checked together with alternator sizing, controller features, enclosure layout, voltage, cooling, exhaust, fuel system, and local compliance requirements.

Selection notes for buyers
Start with duty and output
Shortlist PSI generator engines around 20-3,300 kWe, then compare prime, standby and frequency ratings against the actual load profile.
Check site constraints
Review diesel or 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.
