Timed Intake Cleaner Dispensing for GDI Valve Deposit Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Gas direct injection (GDI) engines are prone to carbon deposits on intake valves, requiring frequent cleaning that is time-consuming and often necessitates multiple persons to perform, with existing automatic systems being cumbersome and inefficient.
Innovation Solution
A self-contained apparatus with a pressure-resistant container, dispensing assembly, and a timer-controlled valve system that allows for single-person, automated cleaning of intake valves by delaying the discharge of an engine cleaner composition into the intake manifold.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual cleaning methods are used, then cleaning can be performed, but it requires multiple persons and is time-consuming
Solution Approach 1:
The system enables self-service cleaning where the engine cleans itself through automated delivery of cleaning composition to the intake manifold, eliminating the need for manual intervention by multiple persons and reducing time loss through autonomous operation
Solution Approach 2:
The patent replaces manual mechanical cleaning operations with an automated system using timers, valves, and fluid delivery mechanisms to dispense cleaning composition, substituting human labor with automated mechanical and control systems
2Ease of operation
If automated cleaning systems are implemented, then single-person operation is enabled, but system complexity increases
Solution Approach 1:
The automated cleaning system is divided into distinct functional modules including timer control, valve actuation, fluid storage, and delivery mechanisms, allowing each component to perform a specific function and simplifying the overall system architecture for single-person operation
Solution Approach 2:
The patent introduces intermediate components such as timers and control valves that mediate between the operator and the cleaning process, automating the coordination of multiple actions and enabling single-person operation without requiring direct manual control of each step
3Reliability
If frequent cleaning is performed, then engine performance is maintained, but time and resource consumption increase
Solution Approach 1:
The system implements periodic cleaning operations with timers that automatically initiate cleaning at predetermined intervals, maintaining engine performance through regular maintenance while optimizing time and resource usage by avoiding excessive cleaning frequency
Solution Approach 2:
The automated system enables continuous or near-continuous cleaning operations to be performed efficiently by eliminating setup and coordination time between cleaning cycles, maintaining consistent engine performance while improving overall operational productivity

AI summary
An apparatus for cleaning an intake system of an engine includes a pressure-resistant container having a reservoir chargable with an engine cleaner composition and a discharge orifice for discharging the engine cleaner composition from the reservoir. The apparatus also includes a dispensing assembly including an assembly inlet connectable to the discharge orifice of the pressure-resistant container for receiving the engine cleaner composition discharged from the pressure-resistant container. The dispensing assembly further includes an assembly outlet, and a length of tubing for receiving the engine cleaner composition from the dispensing assembly. The apparatus further includes a timer configured to control a timed valve that, when opened, allows the engine cleaner composition to discharge from the pressure-resistant container. The timer is configured to delay opening of the timed valve for a predetermined period of time after actuation of the timer.
