Kompatibilní vysokotlaké čerpadlo (Sestava palivového okruhu)
Pracuje na stejném vysokotlakém okruhu Common Rail. Při poklesu tlaku (P0087) ověřte dodávku čerpadla před výměnou vstřikovačů.
Pokyny k montáži
- Always counter-hold the pump body outlet adapter: Loosening or tightening the metal line flare nut without holding the body hex will shear the pump internal thread boss.
- Never reuse the rubber flange O-ring: Reusing an aged radial seal causes severe oil leakage down the engine block onto the steering rack.
- Inspect drive coupling teeth: Inspect the camshaft-driven drive tang; if teeth show fretting wear, replace the intermediate drive cup to prevent sudden pump seizure.
- Mandatory ignition pre-priming: Turn ignition ON without pressing brake pedal for 10 seconds three times to run the low-pressure pump and purge all air pockets before first crank.
Chybove kody (DTC) a diagnosticke protokoly
Bezne diagnosticke chybove kody (DTC), ktere se spousteji pri opotrebeni, zavade obvodu nebo odchylce kalibrace tohoto vstrikovace common rail:
Fuel Rail / System Pressure Too Low
Excessive internal backleak from worn control valve seats drops common rail pressure below target under engine load.
Injector Circuit Malfunction / Open Circuit
Solenoid coil resistance drift (0.2-0.5 Ω) or piezo stack degradation triggers driver stage shutdown on affected cylinders.
Cylinder Misfire & Balancing Deviation
Carbon-clogged nozzle spray holes or missing IMA calibration causes uneven cylinder contribution. Recode ECM and verify washer seating.
Fuel Rail / System Pressure Too High
Spill line backpressure or stuck metering valve prevents rail depressurization, creating overpressure risks under load.
