摘要： The invention relates to a piezo injector (1), comprising a piezo element stack (3) (piezo stack) mounted in an injector housing (2), wherein the piezo element stack (3) is indirectly connected to a valve needle (5) by means of a connecting element (4). It is essential to the invention: that a piston arrangement (6) is provided between the valve needle (5) and the piezo element stack (3), wherein said piston arrangement has two pistons (8, 9), namely a first piston (8) and a second piston (9), connected to each other by means of a spring lying therebetween; and that the connecting element (4) and thus the piezo element stack (3) are connected to the first piston (8) of the piston arrangement (6) in such a way that a transfer of axial forces between the piezo element stack (3) and the piston arrangement (6) is substantially possible, and wherein the second piston (9) is directly connected to the valve needle (5). Thus the piezo injector (1) can be quickly opened and closed with little wear.

摘要： The housing (1) has a knock sensor (12) for producing signals (28) representing a combustion performance. A drill-hole (16) is guided from a housing wall (14) to a housing interior space. An acoustically conductive transmitting medium (18) e.g. metal pin, arranged in the drill-hole acoustically couples the sensor arranged outside at the housing. The drill-hole is provided in a crankshaft wall (15) and extends to a crankshaft main bearing (10), where the acoustically conductive transmitting medium and the knock sensor form a structural unit.

摘要： An injector nozzle (80) for internal combustion engines, having a sensor (50) in the inner or outer area thereof in order to measure the flow of fuel through said injection nozzle or another status parameter of the fuel. The sensor (50) is connected to the outer area via a pressure-tight electric leadthrough (9) disposed in the housing (81) of the injector nozzle (80). The exact amount of fuel injected individually into the combustion chamber is controlled by a feedback sensor/actuator system.
