China Tonglint Turbo Technologies Co., Ltd. Company Cases

Tonglint products are warranted to be free of defects in materials and processing technic for a period of 6 month from the installation by the end user, or 12 months from the date of the arrival at the port of destination.   During this period Tonglint will repair or replace, at its option, any product that proves to be defective. Failure due to improper installation, abuse, poor maintenance, misuse or accidental damage shall be denied. Tonglint shall be the sole adjudicator for all warranty determination.   The following conditions (Turbo failure due to improper installation, abuse, poor maintenance, misuse or accidental damage) will be denied.   Ⅰ. Dirty oil damages the turbocharger by causing heavy scorch of critical bearing surfaces.   Ⅱ. The turbocharger bearing system shows signs of heat discoloration as well as polished and burnished surfaces, due to the insufficient oil supply.   Ⅲ. Impact damage caused by foreign objects entering the turbine housing or compressor housing, visible on the turbine and compressor wheels.   Ⅳ. User dismantles and assembles turbo on his own.   Ⅴ. The housing / wastegate damaged by user.    

Before Installation   ● Understand why the turbocharger needs replacing, determine the cause of any failure and rectify it before fitting a replacement unit.   ● Ensure that the turbocharger is fitted to your engine, or the warranty will be invalid due to the wrong application.   ● Ensure the engine intake/exhaust systems are clean and without foreign objects (free from oil, gasket pieces, dust, dirt, carbon or other debris). Replace air filter if necessary.   ● Ensure the oil inlet and outlet flanges are clean and free from obstruction, internal carbon and sludge. Replace the new ones if necessary.   ● Replace the oil & filter, ensuring that only OEM recommended parts and specified oil are used (oil level ≥ 40CF). ​   During Installation   ● The orientation of the end housings may need changing in order to align correctly with all other connections. If so, ensure all fastenings are tightened to the specified torque.   ● Mount the turbocharger on the exhaust flange, check that the turbine inlet gasket fits correctly to give a gas tight seal.   ● Fill the turbocharger oil feed hole with the clean oil (see Figure below), and slowly rotate the rotor by hand to make the oil reaches to all the bearings.   ● Start the engine and idle checking that all air, gas and oil connections are tight and free from leakage. ​   Attention   ● Never take the turbocharger wastegate brackets as the lifting handle during transportation or installation.   ● Where wastegate brackets are connected to the compressor cover, the orientation of the end housings relative to each other, must not be changed.   ● Avoid any foreign objects into the turbocharger, during removing and installing one unit.   ● Start the engine, idle for 3-5 minutes before loading up, to make sure of good lubrication of turbocharger.   ● Turn off the engine after idling 3-5 mins, to avoid overheating, oil coking and bearing damage problems.   ● Regular inspection and good driving habits can effectively extend the lifetime of a turbocharger.  

A turbocharger is a device that boosts the power output of an internal combustion engine by increasing the amount of air entering the engine. Here's how it works:   Exhaust Gas Collection: As the engine runs, it burns fuel and air, producing exhaust gases. These hot exhaust gases are directed towards the turbocharger's turbine.   Turbine Spin: The exhaust gases flow through the turbine, causing it to spin. The turbine is connected to a shaft that also drives a compressor on the other side.   Air Compression: The spinning of the turbine causes the compressor to spin as well. The compressor draws in outside air, compresses it, and forces it into the engine's intake manifold.   Increased Air Pressure: By compressing the air, the turbocharger increases the amount of air that can enter the engine cylinders. More air allows for more fuel to be injected, leading to a more powerful combustion.   Enhanced Combustion: With more air and fuel in the cylinders, the engine can burn the mixture more efficiently, producing more power compared to a naturally aspirated engine of the same size.   Wastegate Control: To prevent the engine from getting too much boost (which could damage it), a wastegate is used to regulate the amount of exhaust gases reaching the turbine. The wastegate opens to allow some exhaust gases to bypass the turbine, controlling the turbocharger's boost pressure.   Intercooler (Optional): Often, the compressed air gets very hot, reducing its density. An intercooler can be used to cool the air before it enters the engine, improving efficiency and power output.     In summary, a turbocharger recycles exhaust gases to compress the intake air, allowing the engine to burn more fuel and air, thereby producing more power. This process increases the engine's efficiency and performance without needing to increase its size.
