Electronic and mechanical throttle body
Delphi Power Train

Delphi Electronic Throttle Controls and Mechanical Throttle Bodies control airflow to the engine. A butterfly valve in the device opens and closes the passage into the intake manifold to increase or decrease the volume of incoming air.

Delphi Electronic Throttle Controls are regulated by an electronic signal from the engine management system. They offer increased system air control versus mechanical systems to enable the application of advanced engine technologies and vehicle control features to help improve engine efficiency. They can be tailored to meet customer needs for airflow, response time, and system position feedback.

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. They are designed to provide manufacturers with packaging flexibility.
