Latest Patents

Dumitrescu holds a patent for a "Gaseous and liquid fuel injection valve with concentric needles." This invention features an injection valve body that houses two separate concentric fuel injection valve assemblies. The first assembly is a pilot fuel needle valve assembly, which includes a first needle that moves along the longitudinal axis of the body between open and closed positions. The second assembly is a gaseous fuel needle valve assembly, which comprises a second needle that also moves along the longitudinal axis. This assembly controls the injection of gaseous fuel into the combustion chamber through multiple gaseous fuel holes formed in the nozzle tip. Notably, at least one of the nozzle tips is rotatable, allowing for adjustments in the position of the pilot fuel holes relative to the gaseous fuel holes. The number of pilot fuel holes differs from the number of gaseous fuel holes, showcasing the complexity and innovation of his design.
