A controller for a motor vehicle having an internal combustion engine, and a device for detecting a fire in a fluid conduit, the device having a fluid state sensor for detecting a state variable of a fluid that is conducted in the fluid conduit, are provided. The determination of a fire situation is performed in a manner dependent on a signal of the fluid state sensor.

An explosion relief valve for a crankcase of an engine includes a carrier plate, a cap, and an annular flame arrestor. The carrier plate includes a valve plate that has a sinuous shape for redirecting flame back into the engine. The flame arrestor includes a plurality of layers of smooth metal sheets, with each layer having a pattern of apertures that is different in size and spacing than the pattern of apertures of its adjacent layer. The apertures of each layer are partially, and only partially, aligned with the perforations of its adjacent layers. The layers are laid flush against each other to minimize or eliminate air space between the layers, leaving only the air channels existing between the apertures of the metal sheet layers as passageways for exhaust gases to be released from the valve.

An engine system includes an engine having a housing and moving parts for converting energy into mechanical motion; and a first containment blanket having a sheet member and a fastening system. The sheet member extends below a bottom of the engine housing. The fastening system holds the sheet member to the engine such that the first containment blanket laterally shrouds the engine housing to contain debris projected from the engine housing.
