Abstract

The injection detection device for Diesel engines has an injection pump, an injector and at least one connecting line between the pump and the injector. There are also detector mechanisms to determine the cross deformation of the connecting line under the action of the pressure of the injected fuel. The detector mechanisms are arranged between clamping devices which tension the connecting line (12) in two non-contacting zones. They are so supported by these clamping devices that the sensitive section of the detector mechanism, at least in the operating position, lies at the middle section (12a) of the line lying between these two zones.
