Abstract
A system for sensing and monitoring the injection of fuel into a fuel injection type engine, such as a diesel engine, including a piezoelectric transducer comprising a piezoelectric collar mounted on the fuel line to sense the change in dimensions of the fuel line due to the surge of pressure created in the fuel line as the fuel is injected through the line into the engine.
