Title: Innovations of Jonas Aspfors in Internal Combustion Engine Technology
Introduction
Jonas Aspfors is a notable inventor based in Nykvarn, Sweden. He has made significant contributions to the field of internal combustion engines, holding 2 patents that showcase his innovative approach to engine design and functionality.
Latest Patents
One of his latest patents involves a four-stroke internal combustion engine. This invention comprises at least one cylinder arrangement, an exhaust conduit, and at least one turbine. The cylinder arrangement features an exhaust port arrangement designed to open and close an exhaust flow area, A. The maximum volume, V, of the cylinder arrangement is a critical aspect of this design. The exhaust conduit connects the exhaust flow area, A, to the turbine wheel inlet area, A, and has a volume that is ≤0.5 times the maximum volume, V. Additionally, the exhaust port arrangement is configured to expose the exhaust flow area, A, at a size of at least 0.22 times the maximum volume, V, when the piston is at the bottom dead center, BDC.
Another significant patent relates to the use of a lubrication oil that forms water-soluble ash when combusted. This invention is designed for an engine system that includes an internal combustion engine and an exhaust gas system featuring a diesel particulate filter. The system captures particulate matter from the exhaust gases, including the water-soluble ash, and collects condensed water formed during cold starts or cold operation. This condensed water is then led through the diesel particulate filter, effectively dissolving and removing the water-soluble ash.
