Abstract: The present invention relates to a nozzle for a combustion chamber (3) of an engine (T) for providing a fuel-air mixture at a nozzle exit opening of the nozzle (2). According to the invention, an extension (5) for guiding the fuel-air mixture extending in the axial direction with respect to a nozzle longitudinal axis (DM) is provided at an air guide element (271b) of a radially outwardly located air channel (27b) of the nozzle (2).

Abstract: A method and apparatus for reducing undesirable air flow in a passenger compartment of a forward moving vehicle taps into an external air stream source to provide a counteractive air flow supply. The counteractive air flow supply is used to introduce at least one generally forward to rearward directed counteractive flow of air into the passenger compartment at a generally laterally central portion of the vehicle in an amount and at a velocity sufficient to counteract at least a portion of a rearward to forward flow of air in the passenger compartment to provide a forward to rearward directed flow of air through a generally laterally central portion of the passenger compartment at a head level of at least one front seat passenger.
