DIAGNOSTIC METHOD OF ESTIMATION OF COMBUSTION CHAMBER TIGHTNESS IN COMBUSTION ENGINES BY MEANS OF VORTEX FLOW--METER WITH ULTRASONIC SWIRLS DETECTION

Treating the engine as a complex object, coupled with the environment by many factors indispensable for its running (such as fuel, air, combustion products, output power), we can consider the above elements as diagnostic symptoms in relation to the technical state of the internal structure of the object under examination. The factors coupling the complex object (engine) under examination with the environment are functions of many parameters characterizing the state of the complex object, e.g. they can be rotational speed functions. The authors of this paper have made an attempt to identify the relationships between the quantity of air sucked-in by the compression-ignition engine and the technical state of some of its elements determining the operation of the complex object (combustion chamber tightness).
