Method for recognising and determining a defective high pressure pump of a common rail system by means of sensor signals and control device for a combustion engine |
摘要 |
The engine (1) has two injection pumps (2, 3) driven by a camshaft/crankshaft of the engine. The pumps convey a fuel into a common rail (4) and into a respective cylinder head of the engine. The common rail has a rail pressure sensor (5), which determines rail pressure and transmits the determined rail pressure to an engine control device (7). A camshaft/crankshaft angle sensor (6) transmits a crank angle of the camshaft/crankshaft to the engine control device. The control device transmits a warning signal to an error memory (9). An independent claim is also included for a method for safe operation of an internal combustion engine. |
