58 AB Volvo Penta / Diesel Engine TAMD71B
13.3 Fuel system
Injection pump, settings................................................. 22° ±0.5° BTDC
Injectors, opening pressure ........................................... 30 (+0.8) MPa, (306 (+8) kp/cm
2
= 4351 psi)
Injectors, adjustment pressure (new spring) ................. 30,5 (+0.8) MPa, (311 (+8) kp/cm
2
= 4424 psi)
13.4 Turbocharger
Charging pressure, min. values (measured in the engine’s inlet manifold at 100% load and wide open
throttle (WOT), air temperature approx. +25°C (77°F). When measuring at a different temperature, the
charging pressure measured must be corrected (see Workshop Manual).
If full power cannot be achieved, the pressure is considerably lower.
