Methods and systems are provided for removing moisture from an engine exhaust system. In one example, a method includes, during a vehicle key-off condition, in response to a higher than threshold exhaust moisture level and a lower than threshold engine run time during an immediately prior drive cycle, operating an electric air compressor to remove the moisture accumulated in the exhaust manifold.

A method for producing a corrosion resistant metal substrate and corrosion resistant metal substrate provided thereby. The method involves forming a plated substrate including a metal substrate provided with a nickel layer or with a nickel and cobalt layer followed by electrodepositing a molybdenum oxide layer from an aqueous solution onto the plated substrate, which is subsequently subjected to an annealing step in a reducing atmosphere to reduce the molybdenum oxide in the molybdenum oxide layer to molybdenum metal in a reduction annealing step and to form a diffusion layer which contains nickel and molybdenum, and optionally cobalt.

The diffusing member of the present invention is disposed in an exhaust pipe to partially block exhaust gas flowing in from upstream of the exhaust pipe, the diffusing member including a ceramic member and a metal member, wherein the ceramic member surrounds the metal member in such a manner that the metal member is partially exposed, and the volume of the ceramic member constituting the diffusing member is larger than the volume of the metal member constituting the diffusing member.

The present disclosure is directed to ceramic honeycomb bodies, systems incorporating such honeycomb bodies, and methods of preparing and/or manufacturing such honeycomb bodies.
