Abstract: A method of cooling a compressor, providing compressed working fluid, in a natural gas based combustion engine is provided. The method includes diverting at least a portion of natural gas from a fuel tank of the combustion engine. The method further includes routing the portion of natural gas towards the compressor. The method also includes providing one or more nozzles disposed at one or more strategic locations of the compressor. The method further includes injecting the portion of natural gas, via the one or more nozzles, inside the compressor. The method also includes allowing the portion of natural gas to diffuse with the compressed working fluid inside the compressor in an endothermic expansion process, to convectively cool the compressor.

Abstract: An internal combustion engine is provided. The internal combustion engine includes an engine block having at least one cylinder. The internal combustion engine includes a cylinder head engaged with the engine block. The internal combustion engine includes a pre-chamber assembly associated with the cylinder head. The pre-chamber assembly includes a pre-chamber in fluid communication with a main combustion chamber. The pre-chamber assembly includes a fuel supply unit in fluid communication with the pre-chamber to selectively supply fuel to the pre-chamber. The pre-chamber assembly includes an auxiliary unit configured to produce oxygen and hydrogen. The auxiliary unit is in fluid communication with the pre-chamber to supply oxygen to the pre-chamber and in fluid communication with the main combustion chamber to supply hydrogen to the main combustion chamber. The pre-chamber assembly includes an ignition unit associated with the pre-chamber to selectively ignite a mixture of fuel and oxygen in the pre-chamber.

Abstract: A gaseous fuel-powered engine includes a fuel injector configured to selectively inject a plurality of gas plumes into the combustion chamber, and a laser ignition system configured to selectively ignite the gas plumes within the combustion chamber. The laser ignition system includes a laser source configured to generate at least one laser beam, and a beam splitter for splitting the laser beam into a plurality of partial laser beams. A focusing unit is provided to direct each partial laser beam to corresponding focal points in the gas plumes within the combustion chamber. A controller is configured to determine an operating state of the gaseous fuel-powered engine, regulate an intensity of each partial laser beam, and operate the focusing unit for directing the partial laser beams within the combustion chamber to ignite the gas plumes at the focal points during injection of the gas plumes within the combustion chamber.

Abstract: A method for controlling combustion in plasma ignition engine is provided. The method includes receiving a signal indicative of a cylinder pressure, determining a location of predefined MBF and COV of IMEP based on the cylinder pressure, and comparing the determined location of predefined MBF with a target location of predefined MBF and the determined COV of IMEP with a target COV of IMEP. When the determined location of predefined MBF has note reached the target location of predefined MBF and the determined COV of IMEP is not less than the target COV of IMEP, the method includes steps to either vary characteristics, such as number of pulses, input voltage, distance between two subsequent pulses, of a plasma shock wave or advance a plasma spark timing. The plasma shock wave is of an order of nanometer.
