Understanding Fuel Injector Flow Rates

Why Flow Rate Matters

Proper fuel injector sizing is crucial for optimal engine performance. Too small, and your engine won't get enough fuel at high RPMs. Too large, and you'll experience poor atomization and inconsistent fuel delivery at low RPMs.

Key Factors Affecting Flow Rate

  • • Target Horsepower: Higher power output requires more fuel flow
  • • Engine Configuration: Number of cylinders affects individual injector requirements
  • • Duty Cycle: Maximum safe operating time for injectors
  • • Fuel Type: Different fuels require different flow rates
