Internal combustion engine, has injection pumps that convey fuel into common rail, where rail has rail pressure sensor, which determines and transmits rail pressure to engine control device

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.
