ABSTRACT:
An apparatus for determining the pressure within the combustion chamber of an engine. The engine has a fuel injector seated within an opening of a cylinder head to inject fuel into the combustion chamber. Combustion chamber pressure acts upon the fuel injector to eject the fuel injector from the cylinder head. A clamping arrangement is provided to mount the fuel injector on the cylinder head and resist the force applied against the fuel injector by the pressure within the combustion chamber. A strain measuring transducer is associated with the clamping arrangement to measure the force that is exerted upon the clamping arrangement by the fuel injector, to thereby indirectly measure the combustion chamber pressure acting against the fuel injector.
