Latest Patents
Kerska's latest patents focus on advanced methods of distributing air within an engine intake manifold. One notable invention is the "Method of distributing air in an engine intake manifold," where he designed a three-plenum air distribution system for internal combustion engines. This system features long runners extending from two side plenums to deliver air and recirculated exhaust gases into the engine's combustion chambers.
A unique aspect of this invention is its acoustically balanced crossover passage, selectively closed by a manifold tuning valve (MTV), which improves engine output torque during low-speed operations. Additionally, a third plenum situated between the side plenums connects directly to the combustion chambers via short runner passages, optimizing torque output at higher engine speeds. The air flow is further controlled by an onboard electronic controller that responds to engine operating signals, adapting the manifold characteristics according to varying engine speeds.
Another key patent, the "Multi-mode intake manifold assembly for internal combustion engines," exhibits similar principles with a focus on enhancing engine performance across different speed ranges. This assembly allows for direct air supply to combustion chambers and employs innovative electronic control for valve operation, marking it as a significant advancement in engine technology.
