摘要:
The present invention relates to a fuel injection arrangement for a diesel type engine configured to use carbonaceous aqueous slurry fuels. The fuel injection arrangement includes an injector nozzle for injecting fuel into a combustion chamber; a pump chamber housing a fuel pumping element for generating a pressurised fuel flow to the injector nozzle along an injection path between the pumping element and the injector nozzle; and a check valve connected to a fuel supply for regulating and supplying fuel to the injection path via a check valve outlet. A region immediately downstream of the check valve outlet defines an outlet region and the check valve is arranged to expose the outlet region to the pressurised fuel flow to facilitate flushing of the outlet region during fuel flow between the pumping element and the injector nozzle.

Apparatus and a method of introducing a primary fuel, which may be a coal water slutty, and a high combustion auxiliary fuel, which may be a conventional diesel oil, into an internal combustion diesel engine comprises detecting the load conditions of the engine, determining the amount of time prior to the top dead center position of the piston to inject the main fuel into the combustion chamber, and determining the relationship of the timing of the injection of the auxiliary fuel into the combustion chamber to achieve a predetermined specific fuel consumption, a predetermined combustion efficiency, and a predetermined peak cylinder firing pressure.

The valve piston is charged with powdered fuel, such as coal, which is initially metered into a fuel transfer channel during a downward stroke of a dosing and ejecting member and then blown via compressed air through the valve piston into the combustion chamber upon completion of the downward stroke of the dosing and ejecting member. A slider is used to allow metering of the fuel without interference from the compressed air. After the fuel charge is metered, the slider moves transversely of the transfer channel to permit entry of the compressed air so that the charge can be blown into the combustion chamber via the valve piston.

The present invention depicts a reciprocating engine actuated by means of anaerobic fuel comprising a piston reversibly actuated inside a cylinder in an N-stroke operation, the piston being in communication with a crank; a feeding means adapted to introduce the anaerobic fuel to a cylinder head accommodating at least one piston and cylinder, in at least one event of each of said N-stroke; an ignition means igniting the anaerobic fuel in or adjacent to the cylinder head, whereat the piston is in at least one predetermined location in the cylinder along each of the N-strokes, so that in each stroke, a predetermined deflagration of the anaerobic fuel is actuating the crank.

A particulate deflagration combustion engine for burning particulate fuel and method. Fine fuel particles are fed to a mixing box by a pre-measured auger system where the fuel is mixed with dried, compressed combustion air in a desire fuel to air ratio. The fuel mixture enters a combustion cylinder where it is ignited by a pair of spark plugs located approximately 120 degrees apart in the walls of the cylinder. The hot combustion gases leave the cylinder and are vented through an exhaust stack. The exhaust stack is connected to air driers supplying dry combustion air to the engine, thereby pulling a vacuum on the air driers and removing moisture from the air driers. A control panel receives input from dew point monitors, oxygen sensors, and infrared sensors provided in the engine to control the operation of the engine.

An organic matter such as sewage sludge (101) is treated by gasifying the organic matter into a combustible gas and using the combustible gas as a fuel for a gas engine or a gas turbine to recover power (energy). In a method of treating the organic matter, an organic matter as a raw material is dried in a drying process (51), the dried raw material is gasified to produce a generated gas (123), and the sensible heat from the generated gas and/or a combustion gas produced by gasification is recovered by using a heating medium in a recovery process. Then, the heating medium heated in the recovery process is introduced into the drying process as a heating medium gas for drying.

A fuel injection system for alternate fuels such as coal-water slurry comprises a conventional fuel injection pump for supplying timed and metered pulses of diesel fuel to an injector assembly. The injector assembly includes a shuttle piston in a cylinder which is connected at one end by an injection line to the pump and at the other end by a passage to an injection nozzle. The alternate fuel is introduced into the injector assembly passage under pressure through a check valve between injection intervals. A bleed passage in the pump delivery valve provides a rapid pressure decay in the injection line following injection, permitting the shuttle piston to return to its starting position under the influence of the alternate fuel pressure. The timed and metered injection pulses are transferred by the shuttle piston from the diesel fuel to the alternate fuel to open the injection nozzle and inject the alternate fuel into an engine cylinder.

A method is described for integrating a plurality of micro-gasifiers comprising gasifiers, filters, and engine sets or turbine gensets or combined cycle gensets by linking them via a common bus wherein air flow and engine fuel flow is regulated by valves controlling gas flow between the bus and engine genset or turbine genset or combined cycle genset.

This disclosure relates generally to the use of gas clathrates. More particularly, this disclosure relates to systems, methods, and apparatuses related to the use of gas clathrates as a fuel source for automobiles. The gas clathrates may first be dissociated into at least one gas and the at least one gas delivered to the prime mover of a vehicle or the gas clathrates may be directly utilized by the prime mover as a fuel source.
摘要:
An apparatus and method for in situ gas-phase formation and deflagration of nitrocellulose. A nitrating agent such as nitric acid and cellulose are delivered separately to a reaction chamber, where a brief heating pulse initiates nitration of the cellulose and deflagration of the nitrocellulose thus produced. Discharge of the high-pressure gases produced by the deflagration from the reaction chamber can then be used to drive an actuator, turbine, etc.
