Pressure measurer for IC engine combustion chamber - has measurement chamber in gap between cylinder head and block for measurement free of influence from vibrating parts

摘要

An arrangement for measuring the pressure in the combustion chamber of an i.c. engine (1) has a pressure transducer connected to a measurement chamber (12). The latter is formed in a gap between the cylinder head (3) and the cylinder block (2). A measurement chamber wall (13) on the cylinder side forms a direct transfer wall and the boundary to the cylinder vol. or combustion chamber (7) in the region of the cylinder wall. USE/ADVANTAGE - Combustion chamber pressure is measured directly without influence of vibrations in engine housing parts.
