Definitions

  • Hot gas handling device and motorized vehicle comprising the device
  • the invention relates to a hot gas handling device, and particularly to an exhaust.
  • the invention also relates to a motorized vehicle comprising the device, in particular the exhaust.
  • Exhausts are widely used in multiple types of motorized vehicles, such as cars, motorbikes, buses, boats etcetera. Exhausts transport hot gasses discharged under pressure from an internal combustion engine away from the engine. Depending on the overall exhaust design, the exhaust gas may flow through one or more of a cylinder head and exhaust manifold, a turbocharger to increase engine power, a catalytic converter to reduce air pollution and a silencer to reduce noise. Exhausts are subject to diverse conditions, such as mechanical loads (shock loads, mechanical vibrations and bending), high temperatures up to 1100° C and above, arising from the exhaust gasses and moisture. Known exhausts are made from metals, such as stainless steel, which are strong, durable, but are also heavy. Moreover, the known exhaust produces noise at such levels that additional devices such as silencers and mufflers need to be employed in the exhaust system. These additional devices add further weight, which increases fuel consumption.
  • the silencer in exhausts of motorbikes can be made from carbon fibres embedded in a high temperature resistant resin.
  • the temperature of the exhaust gasses discharged from the engine has significantly decreased as they enter the silencer. This also holds for components like a catalytic converter for instance.
  • a hot gas handling device in particular an exhaust, which is lighter than the known exhausts made from steel.
  • this object is achieved by a device for handling hot gasses, and in particular by an exhaust for exhaust gasses discharged from an internal combustion engine, the device comprising a housing, enclosing a space for transporting the hot (exhaust) gasses, wherein the housing is provided with an entrance-opening for the hot gasses discharged from the engine and an exit-opening for transporting the hot gasses away from the engine, wherein the housing comprises a flexible thermal insulating layer, which insulating layer is arranged for resisting the temperature of the hot gasses discharged from the engine, and a supporting structure at a side of the insulating layer opposite from the space, which supporting structure is made of reinforcing fibres embedded in a matrix, wherein the housing further comprises a liner facing the space, the liner comprising a porous fibrous structure.
  • the liner of the device comprises metal and/or mineral fibers, such as glass fibers.
  • the liner comprises a fibrous spiral, a fibrous mesh and/or a fibrous braid.
  • the insulating layer allows the use of a supporting structure made of fibres embedded in a matrix, which results in a device for handling hot gasses, and in particular an exhaust, which is lighter than the known devices made from steel.
  • a flexible insulating layer allows for the deformation of the insulating layer. Increasing pressure of exhaust gasses in the exhaust will deform the insulating layer, thereby increasing the cross-section of the exhaust. This leads to a decrease of the pressure of exhaust gasses, which results in an increase of power of the engine.
  • exhaust is in particular meant the header-back, which is the part of the exhaust from the outlet of the manifold to the final vent to open air.
  • the manifold itself may also be part of the exhaust according to the invention.
  • insulating materials may be suitable for insulating the support structure. All that is required is that the insulating layer is arranged for resisting the temperature of the exhaust gasses discharged from the engine.
  • the insulating layer and the support structure can be designed as separate parts.
  • the insulating layer and the support structure can also be integrally formed, e.g. by using a pile fabric, wherein the lower side of the pile fabric is embedded in the matrix of the support structure, thereby forming the reinforcing part of the support structure.
  • noise generated by the hot gasses flowing at high speeds is unexpectedly well damped.
  • the high frequency harmonics are well damped.
  • the use of noise reduction means such as mufflers and silencers is no longer required, which makes the whole hot gas handling device considerably lighter and of simpler construction than the known device. Further, it turns out that, contrary to expectations, it becomes possible to reduce the very high temperatures at the inside of the device or exhaust to manageable temperatures at the outside thereof, typically from 700-950 °C and more inside the exhaust device to 150-250 °C at the outside.
  • the liner further offers resistance to ablation, especially in corners and/or bends of the device.
  • a further advantage in this respect is that the fundamental of the noise wave can be attenuated or damped easily by changing the shape of the cross-section.
  • Still another advantage is that the device and the exhaust in particular can be fastened to a substructure such as a vehicle in a rigid way.
  • a metal exhaust for instance needs to be fastened in a flexible way such that the important thermal expansion in the length direction of the exhaust (several cm) can be accommodated.
  • a flexible attachment produces low frequency noise waves that are not easily dampened.
  • the device according to the invention does not have this drawback.
  • the flexible thermal insulating layer comprises a first layer facing the space, arranged for withstanding a first temperature and a second layer at a side of the first layer opposite from the space, arranged for withstanding a second temperature, wherein the first temperature is higher than the second temperature, and wherein the second layer comprises a specific heat capacity higher than 0,5 (kJ/(kg*K)), preferably higher than 0,6 (kJ/(kg*K)) and most preferably higher than 0.7 (kJ/(kg*K)).
  • a thermal insulating layer comprising a first and second layer allows for more design flexibility of the exhaust.
  • the second layer can be chosen to have higher heat capacity at the expense of a lower heat resistance, due to the presence of the first layer facing the space.
  • the temperature of the support structure is lower due to the increased heat capacity of the second layer.
  • both the reinforcing fibres as well as the matrix can be selected, thereby giving more freedom to design.
  • the second layer provides for sufficient specific heat capacity, while being sufficiently heat resistant, wherein the second layer can be designed low weight and thin.
  • the first insulating layer is a permeable fibrous structure, comprising fibres selected from the group consisting of: steel, silicium, calcium, aluminium, titanium, zirconium, platinum and combinations thereof.
  • an insulating layer made from such materials can be designed relatively thin while providing high heat insulation.
  • a thin insulation layer allows for the use of a smaller support structure for a given space, which leads to a more lightweight exhaust.
  • a particular suitable material is Superwool ® , from the company Thermal ceramics.
  • Superwool ® is composed of silicium (50-82 wt%), calcium and magnesium (18-43 wt%), aluminium, titanium and zirconium (less than 6 wt%), and trace oxides.
  • the second layer comprises a material with a closed cell structure. This allows for a moisture barrier from the exhaust gasses towards the support structure and may increase the durability of the exhaust.
  • the second layer may also comprise a material with an open-cell structure, which provides the second layer for increased elastic properties. For a given pressure, the second layer will deform more, thereby increasing the effective cross-section of the exhaust for transporting the exhaust gasses, which provides the engine with increased power.
  • the second layer comprises an aerogel.
  • An aerogel comprises a high heat capacity and is lightweight, as it comprises a relative high percentage of air, up to 90%.
  • Aerogel is a silicum-based substance, derived from silicum gel. Aerogel can have a density as low as 1 mg/cm 3 . For comparison the density of air is 1.2 mg/cm 3 . Aerogel combines good thermal insulating properties with high a heat capacity.
  • the second insulation layer preferably comprises micro-fibres.
  • Preferred fibres are metallic, carbon, silicium and glass fibres.
  • the supporting structure may comprise varying reinforcing fibres.
  • the reinforcing fibres are sufficiently heat resistant to resist the temperature as conducted through the insulation layer.
  • Sufficiently heat resistant reinforcing fibres have a melting temperature of at least 200 °C, preferably at least 300 °C, and most preferably at least 400°C.
  • a melting temperature cannot clearly be indicated or determined.
  • Sufficiently heat resistant amorphous fibres are able to withstand the temperatures indicated above in a tensile test conducted at these temperatures and at a tensile stress of 10% of their room temperature tensile strength for an hour.
  • the support structure comprises reinforcing fibres selected from the group consisting of: polyamide fibres, polyester fibres such as Vectran®, carbon fibres, PBO-fibres (Poly(p-phenylene-2,6-benzobisoxazole)), aramide-fibres, steel-fibres, platinum- fibres, PBI fibres (Polybenzimidazole), glass fibres, silicon carbide fibres and combinations thereof.
  • Such fibres combine low weight with high strength and temperature resistance. Combinations of the reinforcing fibres provide for further increased design flexibility and may increase impact resistance of the support structure.
  • the support structure may comprise fibres different from the first insulating layer.
  • the support structure may also comprise the same fibres as the first insulating layer, or a mixture of fibres different from the first insulating layer and the same fibres as the first insulating layer.
  • the supporting structure may comprise varying matrix materials.
  • the matrix material is sufficiently heat resistant to resist the temperature as conducted through the insulation layer. With sufficiently heat resistant is meant that the matrix material has a glass transition temperature Tg of at least 90°C, preferably at least 140 °C, and most preferably at least 190°C.
  • the matrix of the supporting structure comprises a matrix, which is composed of a polymeric material, and more preferred of a material elected from the group consisting of poly-imides, epoxy, phenol- formaldehyde, melamine and combinations thereof.
  • the matrix comprises a mineral polymer. Preferred mineral polymers are described in WO0024690 and in US6103007, both documents being incorporated in their entirety by reference in the present application.
