Nearly 160 members of the Willys-Overland-Knight Registry (WOKR) held their 56th Annual International Meet-up in Jasper, Indiana. During their June 20-23 visit, many of the members took time to tour JASPER's Wernsing Road and Power Drive facilities.
The WOKR was established to bring together people interested in the preservation of vehicles powered by "seeve-valve" engines, or the related family of Willys-Overland vehicles from 1903 to 1942. Nameplates included: Willys, Overland, Whippet, Stearns, Marion and other vehicles powered by a Knight sleeve-valve engine.
By definition, a sleeve-valve fits between the piston and the cylinder wall of an engine where it rotates, or slides. Ports, or holes, in the sides of the sleeves come into alignment with the cylinder's intake or exhaust ports at the appropriate stage of the engine cycle.
Thanks again for the visit WOKR, we appreciate your efforts in the preservation of these historic vehicles!
