摘要： A crankshaft bearing shell in an internal combustion engine of a vehicle is made from a steel/aluminum composite material and is composed of a steel supporting layer and an aluminum plated sliding layer containing parts of tin and copper in the aluminum sliding layer, optionally comprising an intermediate layer consisting of pure aluminum. The aluminum sliding layer comprises A1Sn (20-23) Cu(1.8-2.3) alloy, optionally containing additions of up to 0.1 wt % of Ni, 0.7 wt % of Si, 0.7 wt % Fe, 0.7 wt % Mn, 0.2 wt % Ti, wherein the sum of Si, Fe and Mn is less than 1 wt %; and impurities form a total amount of less than 0.5 wt.- % with the aluminum sliding layer having a Brinell hardness of at least 45 HB 1/5/30 after heat treatment.

摘要： An air gap insulated exhaust manifold for an internal combustion engine of a motor vehicle that has a catalytic converter. The exhaust manifold includes an inner pipe and an outer pipe with a connecting flange on the cylinder head side of the outer pipe. The outer pipe encloses the inner pipe and is spaced therefrom at a distance. A pipe end of the inner pipe protrudes in a guided manner into the cylinder head and only the outer pipe is fastenable to the cylinder head by way of the connecting flange.

摘要： A fastening device for connecting a valve spring retainer to a valve stem has a clamping sleeve, which acts radially on the valve stem and which blocks the valve spring retainer axially against the force of a valve spring on the valve stem, with the valve spring retainer being held displaceably on the valve stem. In order to provide a fastening device between a valve spring retainer and a valve stem of an internal combustion engine that is functionally dependable over a long operating period and is easy to assemble and disassemble, it is provided that the valve stem has, at least in the region of the clamping sleeve, a continuous cylindrical circumferential surface and that the clamping sleeve consists of a shape memory alloy.
