Abstract

A method of making a throttle body assembly, includes casting a main body portion having a passage there through and mounting features for pivotally mounting a throttle valve within the passage. An annular spigot is formed by 3-dimensional printing and is welded to the main body portion in order to provide a quicker less expensive method of prototyping.

Description

technical field [0001] The present invention relates to a method of manufacturing a throttle body, and more particularly, to a method of manufacturing a throttle body for rapid prototyping. Background technique [0002] This section provides background information related to the present disclosure which is not necessarily prior art. [0003] Throttle bodies are commonly used in the intake system of internal combustion engines to control the flow of air to the engine in response to driver activation of the accelerator pedal. The throttle blade is mounted in the throttle body which regulates airflow. Movement of the accelerator pedal may be transmitted via a cable to a linkage that moves the throttle blade. In an electronic throttle control system, an electric motor may be used to control the throttle linkage, which responds to a throttle pedal position sensor. The engine control unit determines the throttle opening based on accelerator pedal position and input from other e...
