Diesel Injector Bosch Fca Psa Opel 1.3

The’injector with original code 1723813 è is a component of the Common Rail injection system used in 1.3 Multijet diesel engines, utilized in vehicles from the FCA (Fiat, Alfa Romeo, Lancia), PSA (Peugeot, Citroën) and Opel/Vauxhall. It is a high-precision injector made on a Bosch basis, which allows for the correct atomization of fuel in the combustion chamber, contributing to efficiency, reduced consumption, and low emissions.

Technical characteristics

L’OE injector 1723813 è of the Common Rail type with electric control, featuring a high-pressure nozzle and electronic adjustment of the injected fuel quantity.à It is part of the Bosch CRI (Common Rail Injector) generation, and è is made of hardened steel to withstand high pressures and prolonged cyclic stress.

The component è is designed to operate at pressures up to 1.600 bar and integrates a control valve that regulates the opening and closing of the’nozzle with millesimal precision. L’injector è programmable and must be electronically adapted to the engine via OBD diagnostics after replacement.

DIPA può intervene to also revise this component whichì is important for the correct functioning of the engine.

Functionalityà

The’OE injector 1723813 has the task of:

• Precisely dosing the fuel in the combustion chamber
• Atomizing the diesel fuel intoù phases (pre-injection, main injection, post-injection)
• Optimizing combustion under all operating conditions
• Ensuring smooth engine response and fuel consumption containment

The engine control unit electrically commands each injector, adjusting its’opening based on the speed, temperature, load, and other operating parameters.

DIPA recommends to always check the compatibilityà of the spare part before’purchase.

Defects and causes

• Pressure loss due to wear of the’nozzle or internal seals
• Blocking due to carbon buildup and residues from incomplete combustion
• Malfunction of the’control solenoid valve, with irregularitiesà in the injection phase
• Difficultiesà in starting, irregular idle, loss of power
• Increased consumption or smokeà at the exhaust

After replacement è it is necessary to perform the programming of the IMA code or injector offset calibration, otherwise operational issues may arise.

Final conclusions

The’OE diesel injector 1723813 è a key component for the 1.3 Multijet/CDTi/HDi engines of the FCA, PSA, and Opel groups. Built on a Bosch basis, it ensures injection precision and reliability.à, but è subject to wear and failures related to contamination and thermal cycles.
