Abstract: An automotive bodywork constructed as a floor pan formed by a platform frame. The platform frame has a structure of the "sandwich" type. It is constructed by overlapping three sheet metal sheets. The intermediate sheet of these three metal sheets is undulated and secured to the other two sheets of metal. Each of the other two sheets of metal are integrally secured to the undulated intermediate sheet where the crests of the undulations contact each other sheet.
Abstract: The device allows the physical quantity used for the feedback-governing of the supercharging pressure of an internal combustion engine to be corrected as a function of ambient air temperature.
