Abstract

The infrared emission mask consists of an external screen (3) fitted to the outlet end (2) of a vehicle engine exhaust pipe so that it lies perpendicular to the exhaust gas flow (S). The area of the screen is greater than that of the exhaust pipe outlet, and it is positioned at a distance (d) from the end of the exhaust pipe equivalent to between a quarter and three quarters of the pipe end diameter (D), being fixed in place by a support (4) in line with the edge of the exhaust pipe, Variants of the design can include a cylindrical or truncated conical collar between the exhaust pipe and screen, which can have two layers with an air gap between them.
