Abstract (en)
The internal diameter of the insulating surrounding sleeve (1) of the manifold is greater than the external diameter of the exhaust manifold tube (2), so that an air gap (4) is formed which reinforces the insulating effect of the surrounding sleeve. This loose insulating sleeve is held in position on the exhaust manifold by means of tubular straps (5) or similar suitable devices. <IMAGE>
Abstract (de)
Der Innendurchmesser der isolierenden Ummantelung (1) des Krümmers ist grösser als der Aussendurchmesser der Auslasskrümmerrohre (2), so dass sich ein Luftspalt (4) bildet, welcher die Isolationswirkung der Ummantelung verstärkt. Dieser lose Isolationsmantel wird durch Rohrbriden (5) oder ähnlich geeignete Vorrichtungen am Auslasskrümmer in Position gehalten.
