Abstract: A residual gas cleaner, comprising a manifold assembly having at least first and second inlets and at least an outlet. The first inlet receives spent exhaust gas from an engine, and the second inlet receives clean gas from a fuel tank assembly. A housing assembly comprises a housing that is secured onto the manifold assembly. The housing collects the spent exhaust gas. The housing assembly further comprises draining means to drain the spent exhaust gas from the housing. A filter assembly comprises a filter extending from the manifold assembly and is housed within the housing. The filter assembly filters the spent exhaust gas to create filtered exhaust gas. The filtered exhaust gas exits the manifold assembly through the outlet to join the clean gas. The engine receives the filtered exhaust gas and the clean gas from the outlet.

Abstract: A turbine assembly comprising a hub and a plurality of vanes. The hub has a plurality of slits angularly disposed thereon. The plurality of vanes, each comprises an interior edge and an exterior edge. Each of the plurality of vanes has curvature and trespasses the plurality of slits. Exterior edges on the plurality of vanes comprise at least two protrusions. The protrusions fill channels defined in an air intake line of an engine, thereby allowing the hub to spin within the air intake line to create a vortex.

Abstract: A spark plug that comprises a terminal and a ceramic insulator. The ceramic insulator has ribs and a shaft. The ceramic insulator also has an insulator that extends from the shaft and terminates at an insulator tip. Extending from the insulator tip is a central electrode post. A ground electrode has a circular wall that extends from threads. The circular wall has a top rim. The top rim has a ridge that protrudes inwardly. The ridge terminates at an interior face.
