During the inter-war period, several original solutions in engine technology were developed. One of them was Wibu dynamic-charge system invented by two young engineers, Adam Wiciński and Jakub Bujak. They succeeded in practically solving the well-known concept of using the inertia of gas column in suction tube to increase pressure of fuel mixture in high -pressure cylinder. They obtained an increase in efficiency up to 30 percent of the engine’s power. During the years 1933-1935, both engineers were working to improve their system and were trying to find possibilities to implement it, i.a. in railcars produced in Poland. Also foreign industry was interested in the invention, i.a. in the United Kingdom and Switzerland. In the end, Wibu system was not implemented and the mere concept of dynamic charge was abandoned for more cost-efficient turbocharging, i.e. forced induction. The history of this invention and its creators has been unknown up to now, partly because of this technological change into forced induction, and partly because of the early death of both inventors. Whereas Wiciński died by suicide in 1936, Bujak vanished without a trace in 1945. The article is based mainly on source materials (authentic period technical articles, patent literature, letters of Jakub Bujak), it presents the history of Wibu concept’s development and outlines the inventors’ profiles.
