    汽车发动机涡轮增压器的常见故障
    来源:http://daryaravandegan.com 发布时间:2019-10-09

    现象一:机油消耗量大,但排气烟色正常,动力不降低。
    Phenomenon 1: oil consumption is large, but exhaust smoke color is normal, power does not reduce.
    原因:这种情况一般是由于机油渗漏造成的。
    Cause: this situation is generally caused by oil leakage.
    处理方法:
    Treatment method:
    (1)首先应检查发动机润滑系外部油管(包括增压器进、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)检查增压器废气排出口是否有机油。如有机油,可判定涡轮一端密封环损坏,应更换此密封环。
    (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.
    现象二:机油消耗量大,排气冒蓝烟,但动力不下降。
    Phenomenon two: large oil consumption, exhaust smoke, but power does not decline.
    原因:由于增压器压器端漏油,机油通过发动机进气管进入燃烧室被烧掉所造成的,有以下几种可能:
    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)增压器回油管不畅通,机油在转子总成的中间支承处积留过多,沿转子轴流入压气叶轮。
    (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)靠近压气叶轮一端的密封环或甩油环损坏后,机油由此进入叶轮室,然后随室内增压后的空气一同经进所管进入燃烧室。
    优配车联
    (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.
    处理方法:
    Treatment method:
    (1)打开压气机的出气口或发动机进气直管(橡胶软管),看管口、管壁是否粘附机油。如有,请检查增压器回油管是否畅通。如不畅通则是由于中间支承处积油过多引起,应将回油管疏通后装复。
    (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)如畅通,则是由于叶轮一端密封环或甩油环损坏所造成,应解体增压器进行修复。
    (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.
    现象三:机油消耗量大,排气冒蓝烟或黑烟,且动力下降。
    Phenomenon 3: large oil consumption, exhaust smoke or black smoke, and power decline.
    原因:
    reason:
    (1)活塞与汽缸之间的间隙磨损过大,机油窜入燃烧室而被烧掉。
    (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)空气在被增压器吸入的过程中,空气流遇较大阻力。(如空滤芯堵塞,进气胶管被吸变形或压扁等),压气机进气口处的压力较低,造成机油渗漏进入压气机内,随压缩空气一起进入燃烧室内烧掉。
    (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.
    处理方法:
    Treatment method:
    (1)检查进气直软管壁内有无机油、是否被压扁,使气流受阻或空滤芯有堵塞现象。
    (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)如管口和管壁有机油,应清洗或更换空气滤芯。
    (2) If there is oil in the pipe orifice and pipe wall, clean or replace the air filter element.
