Abstract
Systems and methods provide for cleaning the air intake valves and surrounding areas of an engine. A gravity-fed cleaning-fluid dispenser may feed cleaning fluid into a hose through a metered device that meters a rate at which the cleaning fluid flows into the hose. A second fluid meter connected to a distal end of the hose further meters the rate at which a mixture of the cleaning fluid and air from is dispersed into the running GDI engine. Cleaning fluid may be distributed to the engine at a gradually decreasing rate as a volume of cleaning fluid in the dispenser decreases as the service progresses.
Claims20
A system for distributing a cleaning fluid to an engine port, the system comprising:
- a fluid dispenser containing a hollow body for receiving the cleaning fluid, the fluid dispenser including a vent, wherein:
- the fluid dispenser comprises a first opening and a lid removably securable in the first opening, and
- the vent comprises a second opening of the fluid dispenser that permits air to passively enter the fluid dispenser when the lid is secured in the first opening;
- a first fluid meter assembly comprising:
- a first fitting coupled to the fluid dispenser and comprising a first fluid passage, which conically tapers from a wider passage closer to the fluid dispenser to a narrower passage farther from the fluid dispenser, the first fitting comprising a male connector with external threads;
- a fluid meter fitting coupled inside the first fluid passage to the first fitting and comprising a second fluid passage that is in fluid communication with the first fluid passage;
- and
- a second fitting comprising a female connector with internal threads, which are coupled to the external threads of the male connector of the first fitting and comprising a third fluid passage in fluid communication with the first fluid passage and the second fluid passage, the fluid meter fitting being positioned between the first fitting and the second fitting, the second fitting being coupled to a valve, which attaches to a first end of a hose;
- a second fluid meter assembly connected to a second end of the hose;
- and
- the second fluid meter assembly adapted to mix air and the cleaning fluid and to dispense the mixture.
A gravity-fed cleaning apparatus for cleaning engine intake valves and surrounding intake areas, the apparatus comprising:
- a fluid-dispersion container having a hollow body for receiving a cleaning fluid, the body having an outlet, a liquid inlet aperture for permitting the cleaning fluid to enter the fluid-dispersion container, and an air inlet vent permitting air to enter the fluid-dispersion container while the cleaning fluid exits the fluid- dispersion container through the outlet, wherein:
- the liquid inlet aperture comprises a first opening and a lid removably secured in the first opening, and
- the air inlet vent comprise a second opening that is separate from the first opening and that permits air to enter the fluid-dispersion container and to exit the fluid-dispersion container when the lid is secured in the first opening;
- a first fluid-flow controller having a first liquid inlet connection and a first liquid outlet connection, the first liquid inlet connection connected to the outlet of the fluid-dispersion container, the first fluid-flow controller including a metering assembly comprising:
- a first fitting coupled to the fluid-dispersion container and comprising a first fluid passage;
- a fluid meter fitting coupled to the first fitting and comprising a second fluid passage that is in fluid communication with the first fluid passage;
- and
- a second fitting coupled to the first fitting and comprising a third fluid passage in fluid communication with the first fluid passage and the second fluid passage, the fluid meter fitting being positioned between the first fitting and the second fitting, the second fitting being coupled to a valve, which attaches to a first end of a hose, wherein the fluid meter fitting comprises:
- a first portion that is inserted into, and contained within, the first fluid passage;
- a second portion that comprises a first chamfered face, which abuts the first fitting;
- and a second chamfered face that abuts the second fitting;
- and
- a second fluid-flow controller having a second liquid inlet connection and a second liquid outlet connection, the second liquid inlet connection connected to a second end of the hose, the second fluid-flow controller including another metering assembly configured to control the flow of the cleaning fluid out of the second liquid outlet connection.
