Engine Valve Cleaner Dispenser for Single-User GDI Intake Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for cleaning intake valves in gasoline direct injection engines are expensive, require professional services, and pose challenges for single users attempting to apply chemical cleaners in their own garages, with environmental and operational difficulties.
Innovation Solution
A dispenser system with a flexible elongate delivery conduit and support clip allows single-handed application of a cleaner to engine intake valves from within a vehicle, using a pressurized canister and actuator components, enabling a steam-like cleaning effect with a water-based solution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If professional services are used to clean intake valves, then cleaning effectiveness is improved, but cost increases and accessibility decreases
Solution Approach 1:
The dispenser system enables vehicle owners to perform intake valve cleaning themselves without requiring professional service. The system includes a pressurized canister connected to a delivery conduit that allows the user to directly apply cleaner to the intake valves through the air intake manifold, transforming a professional service into a do-it-yourself maintenance task
Solution Approach 2:
The dispenser acts as an intermediary device between the cleaner chemical and the intake valves. It provides a controlled delivery mechanism that ensures proper application of the cleaner while protecting the user from direct contact with chemicals and eliminating the need for disassembly of engine components
2Reliability
If chemical cleaners are applied manually to intake valves, then cleaning capability is improved, but operational difficulty and safety risks increase
Solution Approach 1:
The dispenser serves as an intermediary that simplifies the cleaning operation. Instead of requiring the user to manually handle chemicals and access hard-to-reach valve areas, the system provides a guided delivery mechanism where the user simply activates the dispenser from a safe position, and the system handles the precise application
Solution Approach 2:
The system replaces complex manual mechanical operations with a pressurized delivery system. The pressurized canister automatically propels the cleaner through the delivery conduit and onto the intake valves, eliminating the need for manual pouring, spraying, or positioning operations
3Reliability
If traditional dispenser designs are used, then cleaner delivery is achieved, but device complexity and storage requirements increase
Solution Approach 1:
The delivery conduit is stored in a nested configuration within the dispenser housing. The conduit can be coiled or folded within the housing structure, allowing a long conduit to be compactly stored without requiring additional external storage space or complex mounting arrangements
Solution Approach 2:
The dispenser housing serves multiple functions: it stores the delivery conduit, houses the actuator components, provides structural support, and guides the conduit during operation. This multi-functionality eliminates the need for separate storage containers and mounting brackets, reducing overall device complexity

AI summary
A dispenser, method and system using a pressurized canister of cleaner for removing deposits from GDI engine valves including components such as an external housing having an actuator including a valve for engaging a valve stem of the canister, a button trigger for activation of the valve and valve stem by a user, and a trigger return spring, to bias the button trigger out of engagement with the valve, an outlet for attachment to a flexible delivery conduit having a support wire guide, where the delivery conduit is wrapped around the external housing during storage, and during operation by a single individual user extends for a length from the vehicle driver seat through an open window or door, under the open hood for engagement with the vehicle engine intake manifold supported on a delivery conduit support clip, to enable one handed operation of the system by a single user.
