Title: Exhaust catalytic converter of an internal combustion engine
Inventor: RUBBERT STEPHAN
IPC: F01N3/20
Filed: 1993-07-06
Abstract: A catalytic converter, especially a pre-catalytic converter, is supported in a housing with the formation of an air gap, which housing has a coolant circuit of the internal combustion engine flowing around it. The air gap is dimensioned in such a way that at operating temperature the pre-catalytic converter bears on the inside wall of the housing over extensive surface areas as a result of thermal expansion. Undesirably large amounts of heat can then be thoroughly dissipated by way of the coolant circuit. When the catalytic converter cools down again the air gap is formed which, especially following a cold starting of the internal combustion engine, ensures rapid heating-up of the catalytic converter to its operating temperature by the hot exhaust gases.

The flowable surfactant mixture provides a base for forming a pseudo-plastic detergent formulation. The pseudoplastic detergent formulation is formed by introducing solid materials such as an anionic surfactants, solid foam regulators, detergent builders and the like. When the solid materials are introduced into the substantially water-free, flowable surfactant mixture, a paste-form detergent is formed. The paste-form detergent does not flow under the action of gravity but upon introducing shear energy into the mixture, the viscosity is reduced and the composition flows under the force of gravity. Upon removing the shearing forces, the composition returns to its pseudoplastic form.
