20100147233Coke burning engine - A coke burning engine is described wherein hot coke fuel chunks are first compressed with air and reacted therewith to form a carbon monoxide rich gas, during a compression cycle time period. Next these primary reacted gases are mixed into and burned with secondary air during a blowdown cycle time period. These fully reacted gases are expanded though an expander engine whose power output drives the air compressor, and yields a net useful engine power output.06-17-2010
20110259286Common rail slurry fuel injector system - A fuel injection system is described for injecting slurry fuels into the combustion chamber of a diesel engine, equipped with a fuel common rail, and fitted with a gas to fuel contactor chamber for dissolving supplementary atomizing gas into the continuous phase of the slurry fuel, at high pressure. Each fuel injector comprises a combined double valve for starting and stopping fuel injection, so that slurry fuel containing atomizing gas is only depressurized when injected into the engine combustion chamber, when such depressurization greatly improves fuel atomization and combustion efficiency. In this way small bore, high speed, diesel engines can be efficiently operated on high viscosity, low cost fuels such as tars from tar sands, tars from coal and biomass, and residual petroleum fuels.10-27-2011

When the power supplying source applies a voltage to the first and second electrodes, electric arc is generated between the first active metal wire and the second electrode to vaporize and combust the metal wire for driving movements of the piston. A method of driving a piston in a cylinder is also disclosed.08-02-2012

20130087109ENGINE - An engine without a compressor or a turbine comprises a combustion chamber for burning a fuel-air mixture formed by mixing a fuel with outside air; and an outside air introduction part for introducing outside air into the combustion chamber. The outside air introduction part comprises an intake main port for introducing outside air into the combustion chamber from the direction along the central axis of the combustion chamber and a plurality of intake sub-ports for introducing outside air into the combustion chamber from the direction toward the central axis. The intake sub-ports comprise ejection openings capable of ejecting outside air toward a collision point inside the combustion chamber. Streams of outside air ejected from the ejection openings of the intake sub-ports mutually collide at the collision point and are thereby compressed.04-11-2013

123037000 MULTIPLE EXPLOSION 1
20110220041Accelerated compression ignition engine for HCCI - An internal combustion engine has cylinder wall cavities located near the top dead center stroke end to allow optimizing the compression ratio in first stage compression, as function of fuel octane number used. The volume of the cylinder wall cavities is designed to be adjustable, even when the engine is operating. Using a conventional piston motion, the second stage compression becomes accelerated as soon the upper piston ring seals-off the cylinder wall cavities. This is due to the sudden significant reduction in volume. During the power stroke, after the upper piston ring opens the cylinder wall cavities; their fuel content is ignited by second stage combustion products. Because the torque required during accelerated compression is no greater than during first stage compression, stresses in the crankshaft are no more than in conventional spark ignition engines. This allows small displacement engines to be of light weight and to be hand cranked.09-15-2011
