Air Intake Control System Connector Positioning for Wiring Simplification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air intake control systems for internal combustion engines face challenges in facilitating the connection of outside conductors to electric actuators, particularly due to the lack of consideration for connector arrangement, leading to complex and inefficient connecting and wiring processes.
Innovation Solution
The air intake control system includes a connector on the housing of the electric actuator positioned towards one axial end of the crankshaft, with the engine main body mounted on a body frame with an inclined cylinder axis and the throttle body arranged lower than the cylinder head, allowing for parallel alignment with the air cleaner and shared use with sensors, reducing the number of connectors needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the connector is arranged on the electric actuator without considering its direction, then the electric actuator can be mounted on the throttle body, but the connecting work of outside conductors becomes difficult and wiring becomes complex
Solution Approach 1:
The connector is positioned to face one axial end of the crankshaft, utilizing the spatial dimension along the crankshaft axis to achieve optimal connectivity. This directional arrangement allows outside conductors to connect to the electric actuator without interference from the engine main body, simplifying both connecting work and wiring routing.
2Ease of manufacture
If the throttle body is arranged at a higher position, then it can be easily connected to the cylinder head, but the overall engine size increases
Solution Approach 1:
The throttle body is arranged in the vertical dimension below the top end of the head cover, utilizing the space along the cylinder axis. This positioning allows the throttle body to be optimally connected to the intake port while maintaining compact horizontal dimensions, thereby reducing overall engine size without compromising assembly ease.
3Adaptability or versatility
If multiple separate connectors are used for the electric motor and sensor, then each component can be independently connected, but the number of parts increases and cost increases
Solution Approach 1:
A single common connector is used to connect outside conductors to both the electric motor and the sensor. This integrated connector consolidates multiple connection functions into one component, reducing the total number of parts and lowering cost while maintaining the ability to independently connect to each component through the shared connector structure.

AI summary
An air intake control system is provided for an internal combustion engine of a vehicle. The control system includes an intake port of a cylinder head for an engine main body, a throttle body having a throttle valve and connected to the intake port, an electric actuator having an electric motor and arranged on the throttle body to drive open or close the throttle valve, and a connector disposed on a housing of the electric actuator in a position facing toward one axial end of a crankshaft. The connector is provided in order to connect to an outside conductor to the electric motor of the electric actuator. The resulting configuration facilitates the work to connecting the outside conductor to the connector.
