0445110340 Fuel Injector – Bosch-Compatible Common Rail Injector for PSA 9H (DW10) Diesel Engine
The 0445110340 common rail solenoid injector (Bosch compatible) – also known by OEM numbers 1980S5 (PSA) and AV2Q9F593BA (Ford) – is a precision fuel injection component engineered for the PSA 9H series diesel engine (DW10 family). This 2.0L HDi powerplant is widely used in Peugeot, Citroën, Ford, and other European passenger cars. This injector restores factory-correct fuel atomization, reduces diesel knock, improves cold-start performance, and helps maintain Euro 4/5 emission compliance. Below we examine its structural advantages, vehicle fitment, common failure signs, installation best practices, and why Rsolid engine parts is your trusted supplier.
1. Structural Advantages of the 0445110340 Injector
The 0445110340 belongs to Bosch‘s CRI2‑18/20 solenoid injector family, offering proven engineering for European light‑duty diesel applications:f
f
‑speed magnetic solenoid – Achieves opening times below 0.2 ms at 1,600 bar, enabling multiple pilot injections per cycle. This significantly reduces the characteristic “diesel clatter” of the DW10 engine and lowers NOx and particulate emissions.
Hardened stainless steel body – Rated for rail pressures up to 1,800 bar and resistant to corrosion, cavitation, and high thermal cycling – ideal for engines operating in diverse European driving conditions.
6‑hole micro‑sac nozzle – Laser‑drilled orifices produce an ultra‑fine fuel spray that matches the DW10‘s swirl‑assisted combustion chamber, improving cold starts, reducing soot, and extending DPF life where fitted.
Balanced hydraulic servo system – Minimizes internal leakage and ensures consistent injection quantity across all cylinders, critical for smooth idle on 4‑cylinder engines and balanced power delivery.
Plug‑and‑play electrical connector – Matches OEM pin assignment and coil resistance (0.23–0.27 Ω), allowing direct ECU connection without modifications.
These features translate into quieter operation, lower fuel consumption, and reliable performance across the engine‘s service life.
