    Abstract: An internal combustion engine system is described herein. The system uses reactor to create pilot fuel from the primary fuel to assist in the ignition of the primary fuel. A controller is used to maintain an operational range of a level of the pilot fuel in an accumulator. The accumulator acts as a buffer to allow the engine to continue to receive the pilot fuel during dynamic and changing conditions of the engine. The controller increases or decreases the rate of production of the pilot fuel by a pilot fuel system to maintain the operational range of the level of the pilot fuel in the accumulator. The controller can receive inputs such as pilot fuel level or power signals from the engine to adjust the rate of production of the pilot fuel to meet engine demand.

    Abstract: A storage tank includes a tank wall, a pressure regulator, a low-pressure coupling, and a fill coupling. The tank wall of the storage tank is configured to contain a stored fluid at an internal pressure within the tank wall, the tank wall including an outer layer, an inner layer, and a regulator mount. The pressure regulator of the storage tank is connected to the regulator mount and is configured to receive a flow rate of the stored fluid and reduce the stored fluid from the internal pressure to an output pressure. The flow rate of the stored fluid is provided, via the low pressure coupling and at the output pressure to an external system. The fill coupling extends through the tank wall and receives the stored fluid from a fluid source to be stored within the storage tank.

    Abstract: A system includes a fuel tank and a dehydration reactor that are configured to provide a primary fuel and a pilot fuel to a power system. The fuel tank is configured to store the primary fuel and is fluidly connected to a reactor feed line and a primary fuel line provide the primary fuel. The dehydration reactor is configured to receive the primary fuel via the reactor feed line and convert a portion of the primary fuel to the pilot fuel and a byproduct. The power system is configured to receive the pilot fuel from the dehydration reactor to initiate combustion of the primary fuel. The power system also includes a cylinder with an internal piston that receives the pilot fuel and the primary fuel, contains the combustion reaction, and generates power from the combustion reaction; and contains the combustion reaction. A pilot fuel injector provides the pilot fuel to the cylinder at a first time to initiate combustion and a primary fuel injector provides the pilot fuel to the cylinder at to generate power via the power system.

    Abstract: A delay circuit for providing natural gas to an engine and systems, components, and methods thereof can comprise a first valve to selectively pass the natural gas from a starter motor configured to start the engine; a delay volume to receive the natural gas from the first valve; and a second valve to selectively pass the natural gas from the delay volume to an inlet of the engine. The natural gas is provided to the inlet of the engine via the delay system according to a predetermined delay by controlling the first valve and the second valve to selectively pass the natural gas to the inlet of the engine according to the predetermined delay.

    Abstract: A system is disclosed. The system can store a fuel reagent such as methanol for conversion into hydrogen to power one or more facility systems via a backup power system. A reactor controller can monitor a power demand of the one or more facility systems and determine whether the power demand is met by a primary power system. The fuel reagent can be provided to a fuel reactor in response to the reactor controller determining that the one or more facility systems are operating at a power deficit to generate an amount of hydrogen that, when provided to the backup power system, causes the backup power system to generate an amount of power that meets or exceeds the power deficit.

    Abstract: A method for estimating damage of a component of an internal combustion engine includes receiving a fuel rate signal indicative of a fuel rate of the internal combustion engine and estimating a temperature value of the component of the internal combustion engine based on at least the received fuel rate signal. The method also includes estimating an incremental amount of damage of the component of the internal combustion engine based on the estimated temperature value of the component of the internal combustion engine, updating a cumulative amount of damage of the component of the internal combustion engine based on the estimated incremental amount of damage, and outputting a notification based on at least the cumulative amount of damage of the component of the internal combustion engine.
