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

摘要

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°, 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.
