Turbocharger Blower and Turbine cleaning

The turbocharger is a critical component of modern diesel engines, boosting power output and improving fuel efficiency by compressing the incoming air. However, over time, the turbocharger’s blower and turbine sides can become clogged with dirt, debris, and oil buildup, reducing its effectiveness and potentially causing engine damage. To ensure optimal engine performance and longevity, it’s important to regularly clean the turbocharger’s blower and turbine sides.

In this blog post, we’ll discuss why cleaning the turbocharger is crucial, the steps involved in cleaning both the blower and turbine sides, and some best practices to follow. We’ll also touch on some common issues that can arise with turbochargers and how to address them. Whether you’re a diesel engine enthusiast or a professional mechanic, this post will provide valuable insights into maintaining and optimizing your turbocharger’s performance.

Keeping the blower and turbine side of the turbocharger clean is essential for its proper functioning. Turbocharger Blower and Turbine cleaning helps to remove carbon, soot, and other debris that can cause the turbocharger to malfunction and decrease its efficiency. Therefore, it is essential to regularly clean a turbocharger’s turbine and blower side to maintain its optimal performance levels.

एक टर्बो का टरबाइन पक्ष क्या है?

टर्बोचार्जर एक डीजल इंजन का एक महत्वपूर्ण घटक है जो इंजन के पावर आउटपुट को बढ़ाता है और इंजन के फ्यूल एफिशियंसी को बेहतर बनाता है। टर्बोचार्जर के दो प्रमुख भाग होते हैं – टरबाइन पक्ष और ब्लोअर पक्ष। टरबाइन पक्ष, जो टर्बाइन हाउसिंग में स्थान रखता है, द्वारा प्रवेश करने वाली धातु गैस को धार्मिक शक्ति में बदलता है। इस शक्ति का उपयोग ब्लोअर पक्ष द्वारा इंजन में उपयोग होने वाली वायु को नियंत्रित करने के लिए किया जाता है। अधिकतम फ़ायदा प्राप्त करने के लिए, टर्बोचार्जर के ब्लोअर और टरबाइन पक्षों को नियमित रूप से साफ करना आवश्यक होता है।

Cleaning of turbine blades and nozzle rings during operation

The combustion of heavy fuel oil in diesel engines leaves dirty deposits on the turbocharger turbine blades and nozzle rings. The following products of combustion cause these deposits on the turbine components:

  • Soot
  • Molten ash
  • Cinders
  •  Incompletely burned fuel
  • Sodium vanadyl vanadate

It is, therefore, an advantage if fuels with a low content of ash, sulfur, sodium, and vanadium are used. The fuel, furthermore, must also be stored, prepared, and handled correctly.

The dirty deposits increase with time, so regular and proper cleaning is essential to remove what has accumulated.
The charging pressure can rise somewhat if dirty turbine components reduce the turbine cross-section. The dirty deposits cause a drop in turbine efficiency and a rise in engine temperatures after the cylinders.

This may mean that the engine output has to be reduced.
In addition, dirty turbine results in rotor unbalance. Heavy deposits of dirt can lead to unacceptably high rotor imbalance.

Experience with turbocharger operation shows that despite regular cleaning while the installation is running, overhauls during which the turbine and nozzle ring are cleaned mechanically cannot be dispensed with. However, if cleaning is carried out correctly and the cleaning system is appropriately sized, the intervals between overhauls can be extended.

Turbine Side Cleaning Procedure

Dry Cleaning of Turbocharger – Turbine Side

Turbine side cleaning

Cleaning Procedure

1) Cleaning is performed at a high engine load of at least 75% at full load.
2) Before connecting the “blow gun”, open the shut-off valve (1) as shown above and make sure that the passage is secured.
3) Fill the container (2) with cleaning agent.
4) Connect the “blow gun” to the valve (1). Open the air valve (3). 5) Next, slowly open the valve (1), you will hear a whooshing sound as the granules are blown. (Injection time about 2 minutes)

Turbine Side Water Washing

Cleaning Procedure

1) Set the engine load to approximately 20% and wait 10 minutes for the engine to stabilize.
2) Open the drain cock of the turbocharger outlet and check the free passage. See Figure 1.
3) Turn the 3-way valve to position 2 OPEN. See Figure 2 for free passage. If OK, switch to rinsing position 3 “Wash”.
4) Connect the water supply to the water cleaning system.
5) Activate the operating valve (see Fig. 1). Then open the adjustment valve and adjust the water flow until the condensate flow is approximately 0.25 l/min.

6) Continue washing with water for 5-10 minutes. Or until the drain water is free of particles.
7) Loosen the operation valve and disconnect the water supply. Turn the three-way faucet to the “closed” position of 1 and check if the water has stopped.
8) Continue this exercise for at least 5 minutes. before raising the load to normal.
9) After washing with water, the engine should be run for at least 1 hour before stopping the engine.
Note: The control valve should open slowly. The operating valve must not lock in the open position. Do not exceed the irrigation time stated in point 6

Cleaning the compressor during operation

How dirty the compressor stage (compressor wheel and diffuser) becomes depends on how clean the drawn-in air is.

Deposits of dirt can build up in the flow ducts if the following substances are in the intake air:

  • Oily or salty mist
  • Solid combustion residues
  • Various kinds of dust

Dirty deposits on the compressor stage negatively influence the compressor efficiency and charging pressure.

This results in higher exhaust temperatures and higher fuel consumption by the engine. Dirty deposits on the compressor can also increase unbalancing of the rotor.

Regular compressor cleaning during operation can significantly prevent or slow fouling buildup. In no way does it replace the regular service work during which the turbocharger is completely dismantled, and the compressor is cleaned mechanically.

The interval between periodic cleanings varies greatly depending on the operating conditions. Generally, cleaning should be performed every 25 to 100 hours of operation.

Blower Side Cleaning Procedure

ब्लोअर साइड का वॉटर वॉशिंग क्या है?

ब्लोअर साइड वॉटर वॉशिंग एक विशेष प्रक्रिया है जो टर्बोचार्जर के ब्लोअर पक्ष को साफ करने के लिए किया जाता है। इस प्रक्रिया में, एक विशेष वॉशिंग सॉल्यूशन टर्बोचार्जर के ब्लोअर पक्ष में डाला जाता है और फिर इसे धीरे-धीरे चलाया जाता है। इस प्रक्रिया में, जल से पैक गंदगी, रसायन और तेल को साफ करने में मदद मिलती है। वॉटर वॉशिंग को नियमित रूप से किया जाना चाहिए ताकि टर्बोचार्जर के ब्लोअर पक्ष को साफ रखने से इंजन की ऊर्जा प्रदर्शन क्षमता और फ्यूल एफिशियेंसी में सुधार होता है।
