ISOLITE presents innovative internal insulation for turbochargers
ISOLITE is going new ways in the development of insulation systems for the exhaust tract. In close cooperation with a leading manufacturer of turbochargers, the insulation specialist has developed a patented multi-component turbine housing which is effectively insulated from the inside using a snap-in insulation.
• Optimized energy conservation in the exhaust tract ensures low CO2 emissions thanks to better preheating of exhaust gas aftertreatment components
• Reduced thermal load on surrounding components allows more flexible material selection
• Snap-in insulation solution replaces cast-in insulation
(firmenpresse) - Ludwigshafen am Rhein, 13 April 2015 – ISOLITE is going new ways in the development of insulation systems for the exhaust tract. In close cooperation with a leading manufacturer of turbochargers, the insulation specialist has developed a patented multi-component turbine housing which is effectively insulated from the inside using a snap-in insulation. This means that the exhaust gas aftertreatment components reach their operating temperature more rapidly without requiring additional heat or energy.
The faster the vehicle catalysers reach their ideal operating temperature of several hundred degrees Celsius, the lower are the polluting emissions relevant for the fleet consumption. Up to now, the necessary temperatures could only be achieved by providing external energy, for example by injecting additional fuel, but this increased the polluting emissions. Increasingly stricter legal CO2 and NOX standards are causing OEMs worldwide to search for alternative solutions in the form of additional insulation systems for use in the exhaust tract. As a result, as much energy or heat as possible is conserved in the front part of the components that conduct the hot gas. This energy is urgently required for heating up the exhaust gas aftertreatment components.
Temperature conservation thanks to innovative internal insulation
ISOLITE meets the current challenges of the market with a newly developed internal insulation in a sandwich design, in which an inner and an outer liner surround the insulation layer. For this insulation, ISOLITE uses the proven XP technology, with the so-called “popcorn effect” allowing the insulation material to increase its volume by up to 30% when heated up for the first time. Besides being suitable for geometrically demanding installation spaces, the material offers a high acoustic absorption potential and a low specific thermal conductivity. With this innovative internal insulation, it is possible to achieve an approx. 10% higher preheating temperature of the exhaust gas aftertreatment components using only one insulation body, whereas two to four external insulation systems are usually required for the same result.
An internal insulation offers various advantages in comparison with conventional external insulations. The reduced thermal load on the turbine housing and the adjacent components allows the manufacturers to be more flexible in their choice of materials. At the same time, an internal insulation is ideally suitable for use in extremely restricted and thus demanding engine compartment geometries as external insulation systems can be dispensed with. The challenges met by the insulation expert also make an important contribution here. On the one hand, the material used allows as little as 25 to 50 % of the usual tolerances, and on the other, the simultaneous development process requires close coordination with the manufacturer of the turbocharger.
