Fuel Delivery

Fuel delivery is vital to vehicle performance and drivability. That’s why we offer premium quality fuel injectors and fuel system components.

Fuel Injectors


SMP designs and manufactures fuel injectors used in Natural Gas applications. Injectors are available in a variety of fits, forms, and functions, including:

  • Compressed or Liquid Natural Gas
  • Top or Side Feed
  • Saturated or Peak and Hold drive
  • Low or High pressure

SMP puts its injectors through the most stringent tests to ensure operation excellence. Typical performance achievements include:

  • ECE R110 certification
  • Life cycle of 1 billion
  • Cold start at -40ºC

Designed for performance under all conditions

Our fuel injectors are flow-matched to each specific application, with advanced laser-drilled metering holes that deliver precise flow and spray patterns for proper injector performance under all conditions. They’re manufactured in our TS16949-certified facility in Greenville, SC, and 100% tested for coil resistance, injector leakage, static and dynamic flow.

Our injectors promote smooth engine operation reducing overall fuel consumption and harmful emissions

High-temp fluorosilicone o-rings enable prolonged sealing of injector under extreme temperature conditions

Stainless steel calibration slide and spring assembly prevents corrosion within the fuel control body leading to an extended service life

Precision wound and trimmed solenoid windings allow the computer to command efficient delivery of fuel

Fuel Rail Assemblies

As an extension of its fuel injector product line, SMP offers a variety of fuel rail assemblies for Mixing Valves and Sequential Port Injection applications. Besides fuel injectors, the fuel rail assembly can also include components such as a temperature sensor, pressure sensor (separate or combined), and pressure regulator.
