A crash-tolerant system arrangement in an engine compartment situated in the front end region of a motor vehicle includes an exhaust emission control system having an essentially cylindrical first catalytic converter housing situated in front of the exhaust gas turbocharger in the travel direction. The exhaust gas turbocharger is mechanically connected to an exhaust gas manifold via a first fastening device, and to an engine block via a second fastening device, the first and the second fastening devices being designed in such a way that a detachment of the connection of the exhaust gas turbocharger to the exhaust gas manifold and/or a detachment of the connection of the exhaust gas turbocharger to the engine block take(s) place within a predefined upper value range for the pressure force.

In an exhaust manifold to be mounted on a cylinder head of an internal combustion engine which cylinder head includes a plurality of exhaust passages, the exhaust manifold includes a gas collector housing with a mounting flange, a gas conducting duct arranged in spaced relationship within the gas collector housing and having a mounting collar, and a hold-down element mounted together with the flange onto the cylinder head and including a recess receiving the collar of the gas conducting duct for retaining the gas conducting duct in engagement with the cylinder head but permitting relative movement thereto.

In an arrangement for limiting the fill level in a fuel tank having a filler neck with a tank inlet end, a valve flap is pivotally supported in the inlet end such that, in an open position, the valve flap is pivoted toward the fuel flow entering the tank during refueling and is connected, by way of a crank arm and a coupling rod to a float which is disposed in an essentially vertical guide tube. The coupling rod extends through the float and has spaced top and bottom stops providing for lost motion coupling between the float and the coupling rod whose weight is sufficient to keep the valve flap in an open position. When the fuel in the tank lifts the float and, after the float engages the top stop, lifts the coupling rod, closing movement of the valve flap is initiated which is then fully closed by the inflowing fuel utilizing the lost motion distance between the float and the bottom stop of the coupling rod.

A constructionally simpler and more reliable pressure-controlled valve device operates with opening pressure which can be switched to low pressure and high pressure on the cooling fluid circuit of an internal combustion engine, partricularly for a motor vehicle. The valve device can be subjected to gas or liquid from inside the cooling fluid container, depending on the operating condition of the engine, and a higher or lower opening pressure is effective depending on the type of pressure load. In such a device, two valves are functionally arranged within one unit such that they are located in parallel and open separately from one another for the different pressure ranges. For this purpose, the closing bodies of the low-pressure valve and of the high-pressure valve are located tightly one upon the other when the high-pressure valve is not open. When the high-pressure valve becomes effective, the flow outlet from the low pressure valve is shut off. It is shut off by a float raised by the cooling fluid.
