| Common Rail Fuel Injector 71794088 0445110187 for Fiat Doblo Idea 1.9 JTD Condition: New Aftermarket Part Note: We recommend replacing the entire set of fuel injectors to ensure the engine’s optimal performance. Due to differences in oil output and atomization concentration between genuine and aftermarket parts, they should not be mixed. Replacing the entire set of injectors helps avoid potential issues. Always use clean oil.

Signs You Need a Replacement
If your equipment is showing any of these symptoms, the injectors & nozzle may be the cause:
- Rough idle or misfire — Uneven fuel delivery from a worn injector causes the engine to shake at idle. On engines, this is often accompanied by a knocking sound under load.
- Black or white exhaust smoke — Black smoke means excess fuel; white smoke indicates incomplete combustion. Both point to injector spray pattern degradation.
- Loss of engine power — A single failing injector reduces cylinder output. Multi-cylinder engines lose noticeable power when one injector flows less than the rest.
- Increased fuel consumption — Poor atomization means the engine burns more fuel to produce the same power. Monitor your fuel burn rate as an early warning sign.
- Hard starting or no start — If the injector doesn’t deliver fuel on cranking, the cylinder won’t fire. This is especially common in cold weather with worn nozzles.
- Fuel in engine oil (dilution) — Fuel leaking past the injector seat seal contaminates the crankcase oil. If the oil level rises or smells of diesel, inspect the injectors immediately.
Replace as a Set
Replace all injectors as a set whenever possible. On engines, mixing old and new injectors creates uneven fuel delivery — the new injectors compensate for the worn ones, shortening their life. When installing, use new copper sealing washers and torque to the specification in the service manual. After installation, run the engine at idle for 5 minutes to bleed air from the fuel system, then check for leaks at each injector connection before putting the machine under load.
Frequently Asked Questions
Can I cross-reference 55191959 with 55192579?
Yes. Both 55191959 and 55192579 are interchangeable OEM numbers for this part. They refer to the same component with the same specifications, just different part number revisions.
I have a 1.9 engine – which version do I need?
This part covers 1.9 applications. To narrow down the exact fit, check your vehicle’s model year and engine code. The same displacement can have multiple engine variants with different fuel systems or emissions equipment.
