20090183491 | Internal continuous combustion engine system - A continuous combustion system for an internal combustion engine includes a reaction vessel external to the engine cylinders. The reaction vessel contains a combustion chamber for sustaining continuous combustion of an air fuel mixture during the operation of the associated engine. The reaction vessel contains an incoming air chamber and an exhaust gas chamber that are each in communication with the combustion chamber. Injected fuel vapor is mixed with scavenged exhaust gas for pre-heating and with compressed air from each cylinder provided during the compression stroke of each piston. The compressed air and fuel vapor mixture sustains the ignited combustion continuously, while exhaust gas is fed to the cylinders to provide working fluid to the engine during the power stroke of each piston. A valve mechanism is provided to control the flow of air from and working fluid to the cylinders at the appropriate times in order to sustain operation of the engine. | 07-23-2009 |
20090057438 | Ultrasonically activated fuel injector needle - A fuel injector intended for use on an internal combustion engine contains an injector needle that is longitudinally driven by an ultrasonic actuator during the time the injector valve is open to provide an atomized fuel spray output of sub-micron droplet sizes. A piezoelectric disk stack is mounted within the injector housing to surround a portion of the injector needle component and is used to provide the mechanical ultrasonic stimulation to the injector valve at the end of the injector needle and set up a corresponding wave-front at the injector valve to atomize the fuel as it leaves the injector nozzle. | 03-05-2009 |
