Latest Patents

Johnson holds a patent for an insulated composite piston. This invention features a crown made of ceramic or other heat-resistant materials, which is secured to an aluminum piston body using a bolt made from a temperature-resistant alloy. The design incorporates a low conductivity interface created by a series of stacked discs that possess low effective thermal conductivity. To accommodate the relative thermal expansion of the components, bellville washers are utilized on the bolt. This arrangement effectively insulates the crown from the piston body, minimizing the temperature gradient across the crown. As a result, the temperature can be maintained at a level that enhances efficiency while reducing noxious emissions.
