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

When data on the fuel pressure in a common rail (2) are to be collected during engine running, the fuel pressure in the common rail is detected every 6 ° rotation of the crank shaft, the cylinder number, the crank angle and the fuel pressure in the common rail are associated with each other for tabulation and are stored in a storage means (12). Thereby, the accuracy of detected data is improved.
