Device for determining the gas sealing efficiency of cylinder head gaskets during engine operation

摘要

In a device for determining the gas sealing efficiency of cylinder head gaskets during engine operation the quantity of leakage gas getting into the coolant circuit is determined by measuring the buoyancy of a measuring vessel arranged in a liquid tank, the gas collecting vessel mounted on the gas separator being connected directly to the coolant circuit by a pipeline, the gas collecting vessel being provided with an oil separator and a float valve, which regulates the gas leakage line to the measuring instrument as a function of the liquid level in the gas collecting vessel. <IMAGE>
