The invention provides a fuel treatment system for cracking hydrocarbons in fuel for combustion engines. The system comprises a primary ducting component having an exhaust gas inlet zone, and a secondary ducting component which includes a fuel enrichment component and a processing chamber. The processing chamber may have an outlet zone connectable to the combustion engine. The inlet zone of the primary ducting component and the outlet zone of the processing chamber may be configured in a heat exchange relationship with each other and in a counter-current gas flow direction with respect to each other. During operation of the system, heat from hottest volumes of the exhaust gas flowing in a furthest upstream portion of the ducting arrangement may be transferred to fuel-enriched exhaust gas flowing in a furthest downstream portion of the processing chamber. The system may include turbulence-inducing formations, including vortex-inducing formations configured in accordance with mathematical sequences such as the Fibonacci sequence.

An engine includes a reformer, a reforming-air adjuster, a reforming-fuel supply unit, a reformed-gas adjuster, and a control unit. The reformer is configured to reform fuel into a reformed gas. When a start signal is input, the control unit controls the reforming-air adjuster and the reforming-fuel supply unit to a reformable state in which the fuel is reformable in the reformer, and the control unit controls the reformed-gas adjuster so that the reformed gas flows through the reformed-gas adjuster with a degree of opening smaller than a normal degree of opening that is a degree of opening of the reformed-gas adjuster when composition of the reformed gas is in a stable state before the composition of the reformed gas becomes in the stable state, for a given period of time including at least a period immediately after the engine starts.

A system and method of managing an on-demand electrolytic reactor for supplying hydrogen and oxygen gas to an internal combustion engine. The system minimizes reactor's power consumption and parasitic energy loss generally associated with perpetual reactors. The system comprises a plurality of sensors coupled to the reactor measuring a plurality of reactor parameters, an electronic control unit coupled to the plurality of sensors and the engine, and a reactor control board coupled to the reactor and the electronic control unit. The electronic control unit: monitors the plurality of reactor parameters and the plurality of engine parameters; determines a reactor performance level; determines an engine performance level; determines a change in the engine performance level to forecast a future engine demand level; and determines an ideal reactor performance level corresponding to the engine performance level or the future engine demand level. The reactor control board regulates the reactor by modifying at least one of electrical current supplied to the reactor, electrical voltage supplied to the reactor, and temperature of the reactor.

A fuel reformer for producing a steam reforming reaction between fuel and water on a reforming catalyst includes a fuel injection part that injects and supplies fuel into the reforming catalyst, and an injection control part that controls an injection amount of fuel by the fuel injection part. The injection control part controls the injection amount in order that a temperature of the reforming catalyst is not lower than a preset given temperature. The fuel reformer further includes a temperature obtaining part that measures or estimates the temperature of the reforming catalyst, and a target value calculation part that calculates a target value of the injection amount, such that the temperature of the reforming catalyst after fuel is injected by the fuel injection part is equal to or higher than the given temperature. The fuel injection part is controlled such that the injection amount coincides with the target value.

Methods and systems are provided for injecting gaseous fuel during an engine start. In one example, a method comprises generating gaseous fuel via a fuel gasification device and injecting the gaseous fuel via a fuel injector. The fuel injector is configured to inject adjacent to an ignition device.

A fuel reformer for producing a steam reforming reaction between fuel and water on a reforming catalyst includes a fuel injection part that injects and supplies fuel into the reforming catalyst, a temperature measurement part that measures a temperature of the reforming catalyst, and a determination part that determines whether a process for recovering the reforming catalyst is necessary. The determination by the determination part is made based on a temperature change of the reforming catalyst when the steam reforming reaction is produced.

Aspects relate to zero-emission propulsion systems and generators using ammonia (NH.sub.3) as fuel for engines and power plants. While ammonia has poor flammability, mixing hydrogen with ammonia (NH.sub.3) may improve flammability and thus facilitate the ignition of an air/ammonia mixture in engines or power plants. Alternatively, hydrogen (H.sub.2) may be supplied in a separate fuel system as a pilot fuel for pilot ignition of an air/ammonia mixture. Hydrogen can also be used in air independent systems along with oxygen (O.sub.2) from an oxygen tank. In addition to hydrogen, other bio or fossil fuels can be used as pilot fuel for pilot ignition of an air/ammonia mixture. An advantage of using existing bio or fossil fuels for pilot ignition is that engines or power plants will have a pilot fuel system with sufficient capacity to maintain normal operations if ammonia is not available.

A fuel supply apparatus includes a material fuel tank, a separator, a condenser, a first fuel tank, and a first storage device. The material fuel tank is to store a material fuel. The separator is to separate the material fuel supplied from the material fuel tank into a first fuel and a second fuel. The condenser is to condense the first fuel supplied from the separator through a primary-order recovery passage. The first fuel tank is to store the first fuel supplied from the condenser through a secondary-order recovery passage. The first storage device is provided in the secondary-order recovery passage to temporarily store the first fuel supplied from the condenser.

A method of serially phased, phase forming a fuel-air mixture for internal combustion engine is disclosed. The technical result increases the compression ratio of the engine, resulting in economical fuel burning and improved environmental characteristics. The method includes a serially-staged, serially-phased formation of the fuel-air mixture for the engine, which includes the following steps: fuel evaporation; obtaining hydrogen-gas fuel by cleavage of the fuel; cooling and optimization of fuel temperature; preparation of air parallel to the preparation of the fuel; direct formation of the fuel-air mixture; mixing of the fuel, containing hydrocarbon gases with air, with an excess air coefficient Kea≧3; enrichment of the desired air-fuel ratio to the excess air coefficient Kea=from 1.0 to 2.8; a mixture enrichment correction; obtaining control conditions of an idling engine power mode by changing the excess air coefficient, as well as by changing the value of the cylinder filling coefficient.
