Abstract: An arrangement for fitting an exhaust cleaning unit (2) in an exhaust passage (1b): An annular resilient component (7) is fitted around the exhaust cleaning unit (2) at a distance from a gasket (5). The annular resilient component (7) has a first contact portion (7a) which comes into contact with a wall surface (3) of the exhaust cleaning unit (2) and a second contact portion (7b) which comes into contact with a wall surface (1b) of the exhaust passage when the exhaust cleaning unit (2) is in a fitted state in the exhaust passage. The annular resilient component (7) keeps the exhaust cleaning unit (2) in a centered position in the exhaust passage with a spring force.

Abstract: In a method for manufacturing of thermochromic material, a target increased luminous transmittance level for the thermochromic material is determined (210). The luminous transmittance level is defined within a predetermined wavelength region. Preferably, this predetermined wavelength region at least partly comprises visible light. A concentration level of a first dopant element is determined (212) for generating the luminous transmittance level of the thermochromic material. The first dopant element is capable of forming an oxide having a high bandgap in its electronic structure, and in a specific embodiment is Al and/or Mg. A VO2-based thermochromic material is doped (214) with the determined concentration level of the first dopant element. At least one second dopant may also be employed.

The engine block comprises cylinder cavities, which cylinder cavities are separated from each other by intermediate walls, each intermediate wall comprising a bolt hole. The method comprises the step of: removing a test specimen from an area of the intermediate wall of the engine block, such that the test specimen comprises the bolt hole.

Abstract: Pollutant decomposition device, including at least one outer transparent sheet and at least one inner transparent sheet being arranged such that a gap is formed between them and such that the gap is in communication with a surrounding gaseous composition on one side of the device such that the gaseous composition can pass through the gap. The device further including a photocatalyst arranged in the gap for depolluting the gaseous composition that pass through the gap. To obtain optimum decomposition efficiency the outer transparent sheet has a high degree of ultraviolet transmittance compared with the inner transparent sheet.
