Latest Patents

One of his latest patents is an electrically heated catalytic converter for an engine. This invention features a substrate for a catalyst, a rod-like metal electrode connected to the substrate, and a casing that accommodates the substrate. The substrate is designed as a scroll-like cylindrical laminated assembly of thin metal sheets wound around the electrode. The electrode extends from the laminated assembly along the central axis, bends towards the wall of the casing, and penetrates it. The electrode is fixed to the casing via an insulating material at the penetration point. When electricity is supplied to the electrode, electric current flows through it to the laminated assembly and the casing, generating heat in the substrate. This design allows the catalyst to quickly reach its activating temperature. The rod-like electrode is formed as a hollow pipe, which minimizes heat mass and maximizes the heat available for the substrate, significantly reducing the heating time.

Another significant patent is the double-walled exhaust pipe for an engine. This invention consists of an outer pipe forming the outer wall and an inner pipe forming the inner wall of the exhaust pipe. The outer and inner pipes are fixed together at the exhaust inlet portion, which serves as a reference point for thermal expansion. The double-walled exhaust pipe includes at least one bent portion, and the inner pipe is divided into longitudinal sections. A sliding connection is provided between the exhaust inlet portion and the bent portion, allowing for relative longitudinal movement of the pipe sections.
