FUEL PRESSURE DETECTION DEVICE FOR COMMON RAIL TYPE FUEL INJECTION DEVICE, AND COMMON RAIL TYPE FUEL INJECTION DEVICE HAVING SUCH FUEL PRESSURE DETECTION DEVICE

In collecting fuel pressure data in a common rail 2 during engine operation, the common rail fuel pressure is detected each time a crank shaft rotates 6 DEG , and the common rail fuel pressure is stored in storage means 12 by associating the common rail fuel pressure with a cylinder number and a crank angle for tabulation, thus providing improved detection data accuracy.
