Abstract
PURPOSE: To detect easily injection timing without remodelling a conventional unit by providing the flexible pipe of a fuel reflux passage with sandwich pressure pieces in a fixed state and then by adding a pressure sensitive element there.
CONSTITUTION: Into reflux passage 2 formed of a flexible pipe such a rubber pipe of fuel injection valve 1, timing detecting tool 3 is inserted. By sandwich pressure pieces 4 supported rotatably by pin 5, reflux passage 2 is compressed. Holding groove 7a at the upstream part of flexible-pipe pressure grooves 7 holds the flexible pipe softly enough not to restrain a flow of reflux fuel, and pressure sensitive element 8 which detects the variation in pressure of the fuel is buried there. Downstream throttle groove 7b restrains the flow of reflux fuel in the flexible pipe without influencing the motion of a needle valve in injection of fuel. The detecting tool of the constitution like this provides the measurement of fuel injection point in time from variation in pressure detected by pressure sensitive element 8, and its structure is simplified.
