Technical characteristics

The OE turbocharger 55266228 è a’unità with variable geometry equipped with an integrated electronic actuator. The turbine housing è made of high thermal resistance cast iron, while the compressor part è constructed from lightweight alloy, with a high-precision machined impeller and dynamically balanced. The heart of the system, namely the central cartridge (CHRA), è pressurized lubrication via the engine oil circuit and designed to withstand high speeds and extreme temperatures. The’electronic actuator allows direct control of the position of the movable vanes on the exhaust side, enabling continuous adjustment of the boost pressure based on load and parameters transmitted by the engine control unit.

Applications on models

Fiat

• 500X
• 500L
• Type
• Doblò (Bus, Cargo, Flatbed)
• Bravo
• Linea

Alfa Romeo

• Giulietta

Jeep

• Renegade
• Compass

Opel

• Combo

DIPA recommends always check compatibilityà based on the specific engine code and chassis number.

Typical defects

• Failure of the’electronic actuator, due to infiltrations, thermal stress or degradation of the internal motor. This results in incorrect adjustment of the variable geometry.
• Jamming of the movable blades, due to soot deposits in vehicles used in urban cycles or low load conditions.
• Excessive play on the’shaft, caused by wear or inadequate lubrication, resulting in smokeà in the exhaust and loss of pressure.
• Breakage of the impeller or blades, due to the ingress of foreign bodies or overheating.
• Core overheating, in the absence of adequate cooling or following improper engine shutdown after heavy use.

Final conclusions

The turbocharger with OE code 55266228 è is an essential component to ensure performance, efficiency, and reliabilityà in the Multijet diesel engines used in Fiat, Alfa Romeo, and Jeep vehicles.
