1. A device for manual operation of cleaning deposits from an internal combustion engine, said device designed to attach to a vacuum port of said engine to draw air through said device with said engine operating, said device allows air flow into the engine before drawing cleaning fluid into said device to mix with air creating a mixture that is channeled through a combustion chamber of said engine, said device comprising:

  • a housing having a cavity defining a chamber;

    said chamber having an air passageway extending completely through said housing, from an inlet side of said housing through said chamber to an exit side of said housing;

    said inlet side of said air passageway defining an air inlet port at entry of said chamber, and said air passageway defining an exit port at exit of said chamber;

    a source of cleaning fluid below said chamber;

    a cleaning fluid passageway extending from bottom of said chamber through said housing;

    entry of said cleaning fluid passageway into said chamber defining a cleaning fluid passageway port;

    a conduit from said source to said cleaning fluid passageway port, a valve fitted within said housing chamber capable of obstructing said air passageway within said chamber, wherein said valve operates a rotational manner from a closed position completely obstructing said exit port;

    said valve is operated by a knob;

    rotating said knob moves said valve through positions partially obstructing said exit port but not obstructing said air inlet port, and through positions not obstructing said exit port but obstructing said air inlet port;

    whereby with said engine operating said valve thereby governs flow of air drawn through said chamber;

    a fluid exit hose communicating with said exit side of said air passageway providing fluid communication to said engine vacuum port;

    wherein with said fluid exit hose connected to said vacuum port of said operating engine, rotating said valve from said closed position draws air across said fluid port, and further rotation of said valve through positions obstructing said air inlet port create a siphoning of said cleaning fluid into said chamber to mix with air before entering said combustion chamber of said operating engine.
