Abstract: The invention relates to a combustion engine equipped with a dual supercharging system in which a mechanical compressor is driven by an electric motor. The method controls a combustion engine with the electric motor being controlled by determining a rotational speed setpoint for positive-displacement compressor using a supercharge volume filling model.

Abstract: A brace for use in a door frame of a vehicle to brace an hydraulic ram in order to move the front interior portion of the vehicle away from the seats of the vehicle is disclosed. The brace includes a frame for fitting over the horizontal portion and "B" post of the door frame. The brace includes a brace mechanism that is self-locking with the brace frame through means of opposing sets of openings formed in the sides of the brace frame. The brace has a handle and brace pin which is inserted into the openings. The brace pin has a notch at the end farthest from the handle portion. Notch openings are formed horizontally on each of the openings on the sides of the frame. Accordingly, when the pin portion is inserted through the side openings, the notch fits through the notch openings and then gravity rotates the handle downward thereby locking the notch against the farther side of the brace frame.
