Delphi Mechanical Throttle Bodies for Small Engines

Delphi Mechanical Throttle Bodies for Small Engines control airflow to the engine. They feature a butterfly valve in the throttle body which opens and closes the passage into the intake manifold to increase or decrease the volume of incoming air.

Delphi Mechanical Throttle Bodies offer a simpler alternative to electronic systems while maintaining excellent durability and reliability. They are mechanically linked to the accelerator and are constructed of aluminum or composite materials. Delphi Mechanical Throttle Bodies are also designed to provide the manufacturer with packaging flexibility.

Benefits

  • Offer integrated idle air control options, including an Idle Air Control Valve (IACV) or an idle air control bypass adjustment screw
  • Optional integrated sensors can be used for more advanced engine control and diagnostics:
    • Throttle Position Sensor (TPS)
    • Manifold Absolute Pressure/Manifold Air Temperature (MAP/MAT) Sensor 
  • Throttle control interfaces include cable over cam or multiple lever linkage 

Delphi Mechanical Throttle Body with Throttle Position Sensor offers manufacturers a good value for engine air control.

Typical Applications

Delphi Mechanical Throttle Bodies for Small Engines are designed for one- and two-cylinder (In-Line and "V") gasoline engines, from 10 hp to 42 hp. They can also be used in flexible fuel applications.

Delphi Mechanical Throttle Bodies for Small Engines can be used for the following:

  • Motorcycles
  • Motor scooters
  • Commercial products
    • Lawn mowers
    • Stationary power generators
  • Power sports products
    • Personal all-terrain vehicles
  • Marine engines

Performance Advantages

Delphi's Mechanical Throttle Bodies for small engine non-automotive applications are integral to electronic fuel injection systems, which offer a significant improvement in performance, fuel economy and emissions reduction compared to conventional carbureted systems.

Delphi offers the benefits of proven experience producing a wide range of non-automotive engine products for motorcycles, marine engines and power equipment.
