Engine Selection for Power Generation OEMs
Key Factors That Impact Performance, Cost & Compliance
Choosing the right engine for your OEM application isn't just a technical decision — it's a strategic one. The wrong choice can lead to performance issues, costly redesigns, compliance failures, and limited market reach.
The right choice, however, becomes a competitive advantage that improves reliability, efficiency, and lifecycle cost.
Power Solutions International (PSI) is thrilled to share a two-part guide that walks OEMs through the complete engine-selection process, from duty cycle and power sizing to fuel strategy, emissions, integration, and long-term scalability.
Define the Duty Cycle (The Foundation of OEM Engine Selection)
Duty cycle determines everything: performance, sizing, fuel strategy, and lifecycle cost.
Duty Cycle Categories
Standby Power
Emergency use, limited runtime
Prime Power
Variable load, extended runtime
Continuous Power
Constant load, 24/7 operation
PSI supports all three configurations with engines designed for standby, limited-time power (LTP), and prime/continuous applications.
Power Output, Efficiency & Engine Sizing for Generators
Oversizing increases cost and fuel consumption. Under-sizing causes overheating, derating, and downtime.
Key Factors in Power Generation Engine Selection
- Required kW output (peak / average)
- Peak vs. average load
- Altitude and temperature derating
- Future scalability
Goal: Match the engine precisely to the real-world operation and our PSI team is ready to help you make the best decision along the way.
Fuel Flexibility: Natural Gas vs Diesel Engines for OEM Applications
Fuel choice affects emissions, cost, availability, and deployment flexibility.
PSI Supports Multiple Fuel Types
When to Choose Each Fuel
Natural Gas
Lower emissions, ideal for stationary/urban.
Diesel
High power density, remote or heavy-duty.
Dual-Fuel
Flexibility for variable fuel availability.
Wellhead Gas
Oil & gas applications with on-site fuel.
