Approximate parameter
）
Rail pressure of above 197 MPa (2010 kgf/cm2, 28600 psi), and below 230 MPa (2350 kgf/cm2, 33400 psi) continues total time for 35 seconds under condition of above 800 min-1 (rpm). [Threshold changes depending on the engine speed. 2000 min-1 (rpm) should be used as a reference] Or, rail pressure of above 220 MPa (2250 kgf/cm2, 31900 psi) continues total time for 1.7 second under condition of below 800 min-1 (rpm). [Threshold changes depending on the engine speed. 700 min-1 (rpm) should be used as a reference]
