The compression system comprises a main fluid inlet adapted to receive a production stream of natural gas; first and second stage scrubbers; first and second compression units; first and second heat exchange units; one or more liquid dump containers; and an engine. The engine operates within a range of 1600-2100 revolutions per minute and the compressed gas comprises a pressure within a range of 360-600 pounds per square inch. The system comprises a weight to thousand cubic feet of gas per day ratio of less than twenty.

A system and method is disclosed for storing a fluid in a storage vessel in liquefied form and delivering it in gaseous form to an end user through a supply line. The system comprises a pressure relief circuit for returning the fluid from the supply line to the vessel when predetermined conditions are met. The pressure relief circuit comprises a return line connected to the supply line and the storage vessel, a diversion line to divert the fluid elsewhere and a switching device operable to direct the fluid to either one of the lines, as a function of predetermined conditions.

The present invention relates, in general, to systems and methods for generating hydrogen from ammonia on-board vehicles, where the produced hydrogen is used as fuel source for an internal combustion engine. The present invention utilizes an electric catalyst unit operating in series with a heat exchange catalyst unit. The electric catalyst unit is used to initiate an ammonia cracking process on-board during a cold start or low load operating condition of the internal combustion engine, where the ammonia cracking process occurs in the heat exchange catalyst unit once exhaust gas from the internal combustion engine has been heated to a threshold temperature suitable to perform the ammonia cracking process.

A liquid-gas separation unit of a dual-fuel engine is provided. The liquid-gas separation unit includes an exhaust conduit and a separator mounted on the exhaust conduit. The exhaust conduit has a first end and a second end distal to the first end. The first end of the exhaust conduit is coupled to a gaseous fuel supply conduit of the dual-fuel engine for receiving a leaked liquid fuel and a gaseous fuel. The leaked liquid fuel is received from at least one injector of the dual-fuel engine. Further, the separator is adapted to separate the leaked liquid fuel from the gaseous fuel before ejecting the gaseous fuel through the second end of the exhaust conduit.

A natural gas fueled vehicle, includes a natural gas fueled Internal Combustion Engine (ICE) to provide motive power to the vehicle. A pressurizable tank is disposed on the vehicle to contain a natural gas. A natural gas adsorbent is disposed in the tank. A fuel supply tube is to convey the natural gas to the ICE. A scroll compressor is on the vehicle to receive the natural gas from the tank and to deliver a first mixture of compressed natural gas and an oil to a gas and oil separator. The gas and oil separator is to receive the first mixture of the compressed natural gas and the oil from the scroll compressor and to separate the oil from the compressed natural gas and to deliver the compressed natural gas to the fuel supply tube substantially free from the oil.

Systems and methods for thermal management of a direct injection propane fuel system are disclosed that include control a temperature of the fuel tank at or below a desired operating temperature to avoid venting of fuel to atmosphere.

An internal combustion engine includes an intake manifold, at least one intercooler, at least one cylinder head with a plurality of piston-cylinder-units, at least one ammonia source, and a controller. Each piston-cylinder-unit includes at least a main combustion chamber, at least one intake valve, and an ignition device. The at least one ammonia source is configured to provide ammonia to each piston-cylinder unit as part of a combustion charge. The controller is configured to control the intercooler to provide a gaseous medium with a temperature of at least 60? C. to the intake manifold, and control a lambda of the combustion charge inside each main combustion chamber to be between 0.9 and 1.2.

An internal combustion engine includes an intake manifold, at least one cylinder head with a plurality of piston-cylinder-units, at least one ammonia source, and at least one hydrogen source. Each piston-cylinder-unit includes at least a main combustion chamber, at least one intake valve, a prechamber coupled to the main combustion chamber, and an ignition device in the prechamber. The at least one ammonia source is configured to provide ammonia to each piston-cylinder unit. The at least one hydrogen source is configured to provide hydrogen to each prechamber, wherein the at least one hydrogen source includes at least one reformer for cracking ammonia.

The disclosure relates to a fuel supply device for supplying a fuel to an internal combustion engine comprising: a fuel store for storing a primary fuel; and at least two parallel fuel supply paths that are connected to the fuel store, on the one hand, and to the internal combustion engine, on the other hand, wherein the primary fuel can be supplied from the fuel store to the internal combustion engine by means of the first fuel supply path for the purpose of combustion, and the second fuel supply path has at least one reforming device that reforms the primary fuel supplied from the fuel tank into a secondary fuel, and to supply at least a portion of the produced secondary fuel to the internal combustion engine for the purpose of combustion.
