Sometimes oil and water are found at the air inlet of the intercooler, and leakage occurs from the connection between the air inlet of the intercooler and the rubber pipe. Many users are unaware of the origin of these oils and water and suspect where the malfunction occurred.

The reasons for this situation are normal and abnormal, mainly including:

(1) Excessive refueling, high oil level;

(2) The added oil is poor and has high volatility after heating;

(3) The floating bearing of the turbocharger of Baotou Beiben Heavy Duty Truck accessory is damaged, the sealing ring is broken or severely worn, and oil is discharged from the compressor end;

(4) Incomplete separation of oil and gas separator;

(5) There is a small amount of water seepage inside the engine of Baotou Beiben Heavy Duty Truck Parts, and the steam separates after heating.

The above are abnormal factors. For new cars, the phenomenon of oil and water accumulation is mostly the result of (1) and (2). Some users believe that adding more oil is wrong. Due to excessive fuel supply, the engine becomes weak and the output power cannot reach the specified value; If the reason is (3), the oil consumption will significantly increase, exceeding 1.56-1.76g/w, accompanied by a pressure drop or abnormal noise from the turbocharger, and blue smoke from the engine.

Sometimes it is normal for oil and water to be present at the inlet of the intercooler of Baotou Beiben Heavy Duty Truck parts:

(1) The turbocharger has a speed of up to 80000/min and adopts fully floating bearings with large radial clearance and pressure lubrication. Although there is a sealing ring, the compressor end cannot leak oil at all.

(2) The mixture from the oil gas separator always contains a small amount of engine oil, fuel vapor, and water vapor.

(3) Gases originally contain moisture, especially in rainy, humid environments (in the south), or when driving in snow, the air humidity is high.

(4) When replacing with new oil, it still contains a small amount of water and volatile substances, which enter the air inlet through the oil gas separator after heating. These factors cause the engine to condense into liquid oil and water at low points in the engine intake duct. If the rubber pipes connected are aged or the clamps are loose, the accumulated oil and water here will leak. If oil and water leaks are caused by the above reasons, it will not affect the normal operation of the engine.

Therefore, to determine whether the oil leakage at the intake of the intercooler is normal or abnormal, it is not only necessary to pay attention to the quantity, but also to carefully inspect and observe the engine operation and fuel consumption. Generally speaking, if the engine starts normally, the exhaust smoke color and running sound are normal, the speed and load can reach the standard values, and there is no abnormal noise or situation, it can be judged as a normal phenomenon. Otherwise, for abnormal situations, different accompanying phenomena (1) 1 (4) should be checked. The normal fuel consumption should be less than 1.55-1.76g/kWh, or eight eighth of dry fuel, which means that 1000 kilograms of fuel requires 8 kilograms of engine oil.
