Abstract: Burning of hydrocarbon fuels in a combustion engine creates pollutants that include carbon monoxide, nitrogen oxides, and various hydrocarbons. Catalytic converter which is designed to reduce such pollutants relies on precious metal catalysts like platinum. There is an ongoing need to find more effective methods of pollution control as well as cheaper alternatives to precious metals. The solution proposed in this disclosure takes advantage of electrical characteristics of exhaust gases. Some of the pollutants in the exhaust gas exhibit positive electron affinity. Such pollutants are converted to negative ions by providing extra electrons. Many of the pollutants have charge distributions which facilitate electrical interactions with the ions. They are attracted to the ions to form clusters. Pollutant clusters formed as such are separated from the rest of the exhaust gas by electric and/or magnetic forces.

Abstract: A novel latch seat for a switching rocker arm assembly used in variable valve actuation (VVA) systems for internal combustion engines. The seat is formed interactively in the assembled switching rocker arm using a novel fixture and press. The press interactively creates a curved dimple of the correct curvature, position and depth while measuring several lash dimensions. Since the latch seat is formed on the assembled rocker arm assembly, the latch seat depth is designed to account for the inaccuracies in the rocker arm assembly parts which create lash. Therefore all of the parts may be made with less precision since the latch seat is sized to compensate for the inaccuracies of all of the parts. The rocker arm assembly parts now may be manufactured to less stringent standards, but result in a rocker arm assembly with same accuracy of rocker arm assemblies manufactured to previous standards.
