Reconditioned Turbo Smart (450) (452) 0.7

The turbocharger with OE code 1600960999 è is a component installed on the gasoline engines of Smart. It is a small-sized turbo, manufactured by Garrett, which uses a radial type compressor housing and an internal wastegate for boost pressure control. The turbocharger allows for an increase in the’volumetric efficiency of the small three-cylinder turbo, improving its performance and responsiveness.à.

Technical specifications

The OE turbocharger 1600960999 è is also identified by the alternative Garrett codes 727211-5001S. The base model è is the Garrett GT1238S, designed for small displacement gasoline engines, with pressure control via mechanical or pneumatic wastegate.

• Type: radial turbocharger with internal wastegate
• Lubrication: engine oil (without liquid cooling)
• Actuator: pneumatic calibrated for standard opening pressure
• Materials: cast iron turbine housing, aluminum compressor housing
• CHRA rotor: with radial bearings, dynamically balanced
• Working pressure: approximately 0,5–0,6 bar (variable depending on the ECU)

Functionalityà

The function of the turbocharger è compress the’incoming air to the engine to increase its densityà and improve thermodynamic efficiency. By utilizing the’residual energy of the exhaust gases, the turbine drives the compressor that supercharges the’intake. In Smart engines of 0,7 liters, the turbocharger ensures a quick response at low RPMs and a’smooth delivery, keeping fuel consumption low. The integrated wastegate regulates the boost pressure by diverting gases when the preset limit is reached.

Defects and causes

The main faults that can affect this turbocharger are:

• Wear of the CHRA (rotating core), which canò cause axial and radial play, resulting in pressure loss and oil consumption.’.
• Seizing or excessive play of the’shaft: a symptom of insufficient lubrication, often caused by contaminated oil or delays in oil changes.
• Stuck wastegate or faulty actuator: canò cause overpressure (overboost) or performance drop (underboost).
• Breakage of the impellers: from ingestion of foreign bodies or excessive overheating.
• Cracks in the exhaust scroll: from thermal shocks or prolonged stresses.

DIPA highlights: the breakage of the turbo mayò have generated metallic shavings that circulate freely in the lubrication system. Before carrying out the intervention, replace the lubricating oil along with the respective filter. After the intervention is completed, briefly run the engine to facilitate the removal of impurities.à and change the oil and filter again.

Final conclusions

The Smart OE turbocharger 1600960999 represents a fundamental component for the’power delivery in Smart series engines. Its compact dimensions and Garrett design ensure reliability.à and good performance with proper maintenance.
