ABSTRACT:
A serviceable exhaust particulate trap for diesel engines comprising, in a preferred embodiment, a concentric dual bath filter including a tubular outer filter element of high surface area, such as pleated paper or the like, acting as a primary filter, and a tubular mesh-packed secondary filter in a central bypass passage. A normally closed pressure relief valve opens to permit bypass flow through the secondary filter in order to limit back pressure acting on the primary filter under various operating conditions. The particulate trap may be combined in a convenient package with a vehicle muffler.
