Product Introduction
The Bosch 0445110059 is a CRI 1.0-generation solenoid injector that prioritises mechanical durability and serviceability – a design philosophy that distinguishes it from later sealed-unit injectors. With a maximum rail pressure of 1,350 bar (19,580 psi) and a static flow of 830 cc/min at 100 bar, this injector delivers the fuel volumes required for 2.2L diesel engines across the Renault, Opel, and Isuzu vehicle families. However, the defining specification of the 0445110059 is its mechanical tolerance – the injector is manufactured with a 6–8 micron plunger clearance, which accommodates the thermal expansion of the cylinder head in commercial vehicle applications where continuous high-load operation is common. In common rail systems where rail pressure is maintained by the high-pressure pump, this clearance ensures consistent injection characteristics across a wide temperature range (−20°C to +130°C), contributing to the injector's reputation for reliability in fleet operations. The serviceable bolted nozzle retainer further enhances its appeal, enabling component-level overhaul without specialised equipment – a feature that keeps operating costs manageable for high-mileage vehicles.
█ Application Coverage – Renault, Opel, Isuzu, and the 2.2L Diesel Family
The 0445110059 is a service replacement across several European and Japanese platforms using the 2.2L diesel engine family:
Renault – 2.2L dCi (engine code G9T) in Laguna II, Espace III, Avantime, Vel Satis
Opel/Vauxhall – 2.2L DTi (engine code Y22DTR) in Vectra C, Signum, Zafira B
Isuzu – 2.2L TD (engine code 4JJ1-TC) in some commercial vehicle applications
Suzuki – 2.2L DDiS in certain model years
The injector's 7-hole nozzle with 0.195 mm diameter orifices and 145° spray angle produces a droplet SMD of approximately 22 µm. It directly replaces Bosch part numbers 0445110060, 0445110061, and Renault OEM number 8200475965, as well as Opel/GM number 55191050.
▐ Technical Specifications – Electrical and Hydraulic Data
| Parameter | Specification |
|---|---|
| Maximum Rail Pressure | 1,350 bar (19,580 psi) |
| Actuator Type | Solenoid CRI 1.0 |
| Coil Resistance (20°C) | 0.95 – 1.10 Ω |
| Peak Pull-in Current | 16 A |
| Holding Current (PWM) | 5.0 – 5.5 A |
| Static Flow @ 100 bar | 830 ± 25 cc/min |
| Nozzle Holes / Diameter | 7 × 0.195 mm |
| Spray Angle | 145° |
| Needle Lift | 0.22 mm |
| Hydraulic Opening Pressure | 210 bar |
| Leak-off Rate (new, idle) | ≤ 18 ml/min |
| Max. Engine Speed | 4,600 rpm |
| Solenoid Inductance | 2.5 mH |
The 2.5 mH inductance, combined with the 16 A pull-in current, provides an opening delay of 270 µs – a response time that is well-matched to the 4,600 rpm governed speed of the 2.2L dCi engine.
◆ Construction Details – The Serviceable Advantage
The CRI 1.0 architecture used in the 0445110059 is designed for component-level serviceability:
→ Bolted Nozzle Retainer: The nozzle is secured by a threaded retainer nut, allowing the needle and seat to be inspected and replaced during overhaul – a serviceability feature that reduces maintenance costs.
→ Through-Hardened Plunger (56 HRC): Manufactured from SAE 52100 bearing steel and through-hardened to 56 HRC, the plunger accommodates 6–8 microns of wear before performance degradation occurs.
→ Brass-Coated Solenoid Housing: The solenoid housing features a brass coating that improves heat dissipation, extending the service life of the enamel winding in commercial vehicle applications.
→ Non-Serviceable Inlet Filter: A 20 µm sintered metal filter protects the precision components from debris, requiring a 5 µm primary filter upstream.
