    Method of cleaning an internal combustion engine and system therefore
    Technical field of the invention
    The present invention relates to internal combustion engines.
    Background of the invention
    Most vehicles such as cars, motorcycles, boats, and portable machinery, such as electric generators, utilize internal combustion engines. Generally, these engines use fossil fuel to operate.
    In the internal combustion engine, combustion of a fuel occurs with an oxidizer (air) in a combustion chamber. The expansion of the high temperature and high pressure gases produced by the combustion process exert forces to mechanical components of the engine transforming chemical energy into useful mechanical energy. Incomplete oxidation during the combustion, or improper combustion, may increase the emissions. Emissions carry harmful substances, such as carbon monoxides, nitrogen oxides, and other greenhouse gases, such as carbon dioxide that can adversely affect health and the environment. To control the emissions, users and manufacturers of internal combustion engines must comply with stringent regulations and emissions control standards.
    For economic and environmental reasons, technologies on fuel and engine have been developed to produce internal combustion engines with improved fuel efficiency and reduced emissions. For example, unleaded fuels are used for reducing carbon deposits in the engine, and fuel additives are used for increasing performance and fuel efficiency of the engine. However, the effects of carbon build-up are still present in almost all vehicles, and the use of some fuel additives may further increase carbon deposits in the engine. Excessive build-up of carbon deposits in the engine will reduce engine performance and create significant drivability issues.
    DK 2016 00715 A1
    It is therefore desirable to provide a system, which can reduce the build-up of carbon deposits in an internal combustion engine.
    Summary of the invention
    The inventor of the present invention has provided a system capable of reducing the build-up of carbon deposits in an internal combustion engine. Surprisingly, it was found that administering repeatable doses of hydrogen gas into the internal combustion engine works even better than using a continuous flow of hydrogen. Without being bound by any specific theory, it is speculated that the hydrogen reacts, in an exothermic reaction, with a) oxygen being co-administered and/or b) oxygen from the air intake duct of the internal combustion engine to form water vapor. These small explosions, and in pulses, releases the carbon deposits from the inner walls of the system, and decreases the NOX emission from the system.
    A first aspect of the present invention relates to the use of a gas delivery system configured to deliver a range of repeatable doses of hydrogen gas and optionally oxygen gas for cleaning an internal combustion engine.
    A second aspect relates to a gas delivery system adapted for cleaning an internal combustion engine, the gas delivery system comprising:
    - means capable of performing electrolysis on water; and
    - means adapted for transferring the produced hydrogen to an internal combustion engine; and
    - a direct current electrical supply configured to deliver direct current pulses of 200-1000 Hertz to the means capable of performing electrolysis on water.

    Detailed description of the invention
    A first aspect of the present invention relates to the use of a gas delivery system configured to deliver a range of repeatable doses of hydrogen gas and optionally oxygen gas for cleaning an internal combustion engine.
    In one or more embodiments, the gas doses are delivered at a frequency of 200-1000 Hertz, such as within the range of 250-950 Hertz, e.g. within the range of 300-900 Hertz, such as within the range of 350-850 Hertz, e.g. within the range of 400-800 Hertz, such as within the range of 450-750 Hertz, e.g. within the range of 500-700 Hertz, such as within the range of 550-650 Hertz.
    In one or more embodiments, the hydrogen gas and the oxygen gas is continuously produced in doses by electrolysis of water.
    When a pulsed voltage is imposed on the terminals of an electrochemical cell a corresponding pulsed current through the cell is produced. In the present context, the pulsed current and pulsed voltage are generally interchangeable. A peak current is turned on for a period of time called the on-time, followed by a zero current for a period of time called the off-time. The sum of on-time and off-time is known as the period of the pulse and the inverse of the period is known as the frequency of the pulse. The percent on-time in a pulse is defined as the duty-cycle of the pulse. The pulsed voltage results in the production of hydrogen gas in pulses (doses).
    In one or more embodiments, the hydrogen gas and the oxygen gas is continuously produced by means capable of performing electrolysis on water, and wherein a direct current electrical supply is configured to deliver direct current pulses of 200-1000 Hertz to the means capable of performing electrolysis on water, such as within the range of 250-950 Hertz, e.g. within the range of 300-900 Hertz, such as within the range of 350-850 Hertz, e.g.

    In one or more embodiments, an internal combustion engine with an engine displacement of 4-6 liters is treated with 250-1,500 liters of hydrogen gas per hour, such as within the range of 300-1,400 liters of hydrogen gas per
    DK 2016 00715 A1 hour, e.g. within the range of 350-1,300 liters of hydrogen gas per hour, such as within the range of 400-1,200 liters of hydrogen gas per hour, e.g. within the range of 450-1,100 liters of hydrogen gas per hour, such as within the range of 500-1,000 liters of hydrogen gas per hour, e.g. within the range of 650-950 liters of hydrogen gas per hour, such as within the range of 700-900 liters of hydrogen gas per hour, e.g. within the range of 750-850 liters of hydrogen gas per hour.
    In one or more embodiments, an internal combustion engine with an engine displacement of 10-20 liters is treated with 750-2,500 liters of hydrogen gas per hour, such as within the range of 800-2,400 liters of hydrogen gas per hour, e.g. within the range of 850-2,300 liters of hydrogen gas per hour, such as within the range of 900-2,200 liters of hydrogen gas per hour, e.g. within the range of 950-2,100 liters of hydrogen gas per hour, such as within the range of 1,000-2,000 liters of hydrogen gas per hour, e.g. within the range of 1,100-1,900 liters of hydrogen gas per hour, such as within the range of 1,200-1,800 liters of hydrogen gas per hour, e.g. within the range of 1,300-1,700 liters of hydrogen gas per hour, such as within the range of 1,400-1,600 liters of hydrogen gas per hour, e.g. within the range of 1,4501,550 liters of hydrogen gas per hour.

    In one or more embodiments, the hydrogen and oxygen gas is mixed with the air entering the air intake duct of the internal combustion engine prior to reaching the internal combustion engine.
    A second aspect relates to a gas delivery system adapted for cleaning an internal combustion engine, the gas delivery system comprising:
    - means capable of performing electrolysis on water; and
    - means adapted for transferring the produced hydrogen to an internal combustion engine; and
    - a direct current electrical supply configured to deliver direct current pulses of 200-1000 Hertz to the means capable of performing electrolysis on
    DK 2016 00715 A1 water.
    In one or more embodiments, the gas delivery system further comprises a controller adapted for receiving user input about the engine displacement of an internal combustion engine to be treated, and in response to said input, instruct the means capable of performing electrolysis on water to produce a specific amount of hydrogen per hour.
    It should be noted that embodiments and features described in the context of one of the aspects of the present invention also apply to the other aspects of the invention.
    The present invention is not limited by a specific type of means capable of performing electrolysis on water. However, an example of a means capable of performing electrolysis on water could comprise:
    an electrolytic cell, for generation of a water electrolytic gas, including an electrolyte inlet (e.g. formed in a bottom wall), an outlet (e.g. formed in a top wall) adapted to extract a mixture of an electrolyte and a generated gas, an anode plate (e.g. internally arranged near the bottom wall), a cathode plate (e.g. internally arranged near a top wall), and an electrolyte spinning and passing portion, for spinning and passing an alkali electrolyte in a direction leading from the anode plate to the cathode plate;
    a separation cell, for an electrolyte/water electrolytic gas, in which gasliquid separation is performed for the mixture that has been extracted from the outlet in the upper end of the electrolytic cell and the mixture that includes the electrolyte and a water electrolytic gas, and as a result, gas components comprising the water electrolytic gas are separated from the electrolyte, so that only the gas components are externally extracted, while an electrolyte component is retained, internally; and
    DK 2016 00715 A1 an electrolyte circulation unit, for circulating, toward the electrolytic cell, the electrolyte that has been retained in the separation cell. The electrolyte spinning and passing portion, which is located between the anode plate and the cathode plate in the electrolytic cell, may comprise a predetermined number of metal plates with a plurality of electrolyte passage openings. The metal plates are arranged by sequentially displacing the electrolyte passage openings at a predetermined angle, so that the electrolyte is passed through the metal plates, while spinning is being performed.
    The metal plates are not electrically connected to the anode plate or the cathode plate, or to another portion or each other. Instead, the metal plates are securely supported by an insulating member.
    Potassium hydroxide (KOH), which is an alkali electrolyte, and water are introduced into the electrolytic cell, and a direct-current voltage is applied between the anode plate, arranged inside, near the bottom of the electrolytic cell, and the cathode plate, arranged near the top thereof, in accordance with the polarities of these electrodes. As a result, the potassium hydroxide (KOH) electrolyte and water are forced upwards in the electrolytic cell, while being spun between the anode plate, located near the bottom, and the cathode, located near the top. During this process, electrolysis progresses, while the reaction for the generation of hydrogen gas (and oxygen gas) continues to develop in the electrolyte solution.
    When electrons collide with a metal plate (that serves as a member of the electrolyte spinning and passing portion), arranged between the anode plate and the cathode plate, oxonium ions (H3O+) are generated by the collisions and are moved to the cathode side, and anions (OH-) are also so generated and are moved to the anode side. When multiple metal plates have been so arranged, a large quantity of water electrolytic gas can be generated in the electrolytic cell. Thereafter, the mixture of the electrolyte and an increased amount of the thus generated hydrogen gas is extracted via the outlet formed in the upper end of the electrolytic cell. As would be
    DK 2016 00715 A1 appreciated by a person skilled in the art, the size of the anode and cathode plates, the magnitude of the electric current (voltage, amperes) used, and the flow and temperature of the electrolyte solution are decisive for the amount of generated hydrogen gas (and oxygen gas).
    The thus extracted mixture of the electrolyte and the hydrogen gas is passed through a connecting pipe to a separation cell, in which gas-liquid separation is thereafter performed to separate the hydrogen gas from the electrolyte. Hence, only the hydrogen gas (and oxygen gas) is extracted via the lead-out pipe, and is transferred to the internal combustion motor. The residual electrolyte is recirculated through the electrolytic cell to continue the above described reaction process.
