現(xiàn)象一：機油消耗量大，但排氣煙色正常，動力不降低。
Phenomenon 1: oil consumption is large, but exhaust smoke color is normal, power does not reduce.
原因：這種情況一般是由于機油滲漏造成的。
Cause: this situation is generally caused by oil leakage.
處理方法：
Treatment method:
（1）應檢查發(fā)動機潤滑系外部油管（包括增壓器進、回油管）是否漏油；
(1) First of all, the oil pipes outside the engine lubrication system (including the inlet and return pipes of supercharger) should be checked for oil leakage;
（2）檢查增壓器廢氣排出口是否有機油。如有機油，可判定渦輪一端密封環(huán)損壞，應更換此密封環(huán)。
(2) Check whether there is oil at the exhaust outlet of supercharger. If there is oil, it can be judged that the sealing ring at one end of the turbine is damaged, and the sealing ring should be replaced.
現(xiàn)象二：機油消耗量大，排氣冒藍煙，但動力不下降。
Phenomenon two: large oil consumption, exhaust smoke, but power does not decline.
原因：由于增壓器壓器端漏油，機油通過發(fā)動機進氣管進入燃燒室被燒掉所造成的，有以下幾種可能：
Causes: the oil leakage at the compressor end of the supercharger is caused by the oil entering the combustion chamber through the engine intake pipe, which may be caused by the following:
（1）增壓器回油管不暢通，機油在轉(zhuǎn)子總成的中間支承處積留過多，沿轉(zhuǎn)子軸流入壓氣葉輪。
(1) The oil return pipe of supercharger is not smooth, and the oil accumulates too much at the middle support of the rotor assembly, and flows into the compressor impeller along the rotor shaft.
（2）靠近壓氣葉輪一端的密封環(huán)或甩油環(huán)損壞后，機油由此進入葉輪室，然后隨室內(nèi)增壓后的空氣一同經(jīng)進所管進入燃燒室。
(2) After the seal ring or oil slinger ring at one end of the compressor impeller is damaged, the oil enters the impeller chamber, and then enters the combustion chamber with the pressurized air in the chamber.
處理方法：
Treatment method:
（1）打開壓氣機的出氣口或發(fā)動機進氣直管（橡膠軟管），看管口、管壁是否粘附機油。如有，請檢查增壓器回油管是否暢通。如不暢通則是由于中間支承處積油過多引起，應將回油管疏通后裝復。
(1) Open the compressor outlet or engine intake straight pipe (rubber hose) to see if the pipe orifice and pipe wall adhere to oil. If yes, please check whether the oil return pipe of supercharger is unblocked. If it is not smooth, it is caused by excessive oil accumulation at the middle support. The oil return pipe should be dredged and reassembled.
（2）如暢通，則是由于葉輪一端密封環(huán)或甩油環(huán)損壞所造成，應解體增壓器進行修復。
(2) If it is smooth, it is caused by the damage of the sealing ring or oil slinging ring at one end of the impeller. The supercharger should be disassembled for repair.
現(xiàn)象三：機油消耗量大，排氣冒藍煙或黑煙，且動力下降。
Phenomenon 3: large oil consumption, exhaust smoke or black smoke, and power decline.
原因：
reason:
（1）活塞與汽缸之間的間隙磨損過大，機油竄入燃燒室而被燒掉。
(1) The clearance between the piston and the cylinder is worn too much, and the engine oil rushes into the combustion chamber and is burned off.
（2）空氣在被增壓器吸入的過程中，空氣流遇較大阻力。（如空濾芯堵塞，進氣膠管被吸變形或壓扁等），壓氣機進氣口處的壓力較低，造成機油滲漏進入壓氣機內(nèi)，隨壓縮空氣一起進入燃燒室內(nèi)燒掉。
(2) In the process of air being sucked in by the supercharger, the air flow meets with greater resistance. (for example, the air filter element is blocked, the intake rubber tube is sucked out of shape or flattened, etc.), the pressure at the compressor inlet is low, which causes the oil leakage into the compressor and enters the combustion chamber together with the compressed air to burn off.
處理方法：
Treatment method:
（1）檢查進氣直軟管壁內(nèi)有無機油、是否被壓扁，使氣流受阻或空濾芯有堵塞現(xiàn)象。
(1) Check whether there is oil in the wall of the air inlet straight hose, whether it is flattened, so that the air flow is blocked or the air filter element is blocked.
（2）如管口和管壁有機油，應清洗或更換空氣濾芯。
(2) If there is oil in the pipe orifice and pipe wall, clean or replace the air filter element.
