An atomizing nozzle for a burner, especially for a vehicle heater has a flow guide element, which provides a flow guide surface and which has an atomizing lip in an end area. It also aims to provide exhaust gas treatment processes and systems capable of efficiently treating oxidizing gases such as F2, Cl2 and Br2; acidic gases such as HF, HCl, HBr, SiF4, SiCl4, SiBr4 and COF2; and CO in addition to PFCs. The device further includes a limit determining control unit determining whether to limit acceleration, and an input torque change speed limiter control unit limiting the change speed to less than the predetermined value when the limit determining unit makes a determination to limit acceleration. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract without departing from certain embodiments of the invention. Solvent, such as diesel fuel, is pumped into the elongate passageways defined between the heaters and screens. In the pneumatic tire, a sagged portion is formed by a concavo-convex structure in the air permeation preventing layer at least between points P and Q in a shape that a length La of a straight line connecting points P and Q and a length Lb of the air permeation preventing layer actually passing through points P and Q satisfy a relationship of \u2266Lb\u2266.
