汽车进水后的维修方法

来源:http://www.sdjnltqf.com发布时间:2017-08-05 11:39:00

1、气缸大量进水时
1 、 when the cylinder is flooded
当水淹没过进气口,水就混合着气体一同进入燃烧室中,而水是不可压缩和燃烧的,此时发动机气缸燃烧室里就会充满油水混合液体,造成发动机熄火。当发动机在涉水熄火时,气缸内已经充满了水,由于水是不可压缩的,活塞也就没有上行的空间,这个时候点火启动发动机,启动机将无法驱动发动机,发动机无法启动,进水后再次启动发动机,将对发动机造成很大损伤。
When the flooded water inlet, a mixture of gases together into the combustion chamber, and the water is incompressible and combustion, the engine cylinder combustion chamber will be filled with water mixture, causing the engine flameout. When the engine is in wading flameout, the cylinder is filled with water, because the water is incompressible, the piston will not start the engine ignition uplink space, this time, start the machine will not be able to drive the engine, the engine can not start, start the engine again after water, will cause great damage to the engine.
维修方法:对发动机进行拆解检查,清除内部积水,检测活塞、连杆、燃烧室缸筒是否发生了形变。对受损的连杆、活塞、燃烧室缸筒进行更换。另外,拆解排气歧管,使进入排气管中的水流出,以免损坏三元催化转换器及排气管消声器。
Maintenance method: disassemble the engine, check the internal water, and check whether the piston, connecting rod, combustion chamber and cylinder are deformed. Replace the damaged connecting rod, piston, combustion chamber and cylinder. In addition, the exhaust manifold is disassembled so that the water entering the exhaust pipe flows out so as not to damage the three yuan catalytic converter and the exhaust pipe silencer.
2、气缸少量进水时
2, a small amount of water into the cylinder
在气缸燃烧室进水很少时,如果发动机可以运转,在转动的瞬间,发动机燃烧室的某个活塞上行完成点火前的压缩工作,进排气门关闭,此刻的气缸燃烧室是一个密闭空间,由于水是不可被压缩的,当活塞上行至接近上止点的一定位置时,阻力会增大,而其它正在做功的活塞推动曲轴快速旋转,由于活塞是通过连杆和曲轴一起运动的,所以曲轴会把这个活塞送到气缸燃烧室上止点位置,而气缸燃烧室内的水会阻止活塞向上止点位置运动。
In the cylinder combustion chamber inlet rarely, if the engine can run in the rotation moment, a piston combustion chamber of the engine to complete the compression work before ignition, into the exhaust valve closed, at the moment of the cylinder combustion chamber is a closed space, because the water can not be compressed, when the piston up to close up check a certain position, resistance will increase, while the other is acting piston to drive the crankshaft to rotate quickly, because the piston is through the connecting rod and crankshaft moving together, so the crankshaft will make the piston to the cylinder combustion chamber TDC, the combustion chamber of the cylinder water will stop to check on the movement position of the piston.
维修方法:当发动机进入少量水时,如果心存侥幸对发动机进行二次点火,当发现发动机动力不足和排气管冒白烟时,立即停车,将汽车拖到修理厂,完全拆解发动机,对发动机连杆、活塞、缸筒进行检测,更换受损零部件。
Maintenance method: when the engine into a small amount of water, if luck on the engine two ignition, when the power of the engine and the white smoke, immediately stop, towed the car to the garage, completely dismantling the engine, detection of engine connecting rod, piston, cylinder, to replace the damaged parts.
3、停车熄火状态进水时
3 、 stop flameout when water inlet
如果是汽车在停车熄火的状态泡水了,进气口、排气管消声器,都被积水淹没,就会出现积水倒灌排气管的现象,积水会通过排气歧管流向排气门处于打开状态的气缸燃烧室。另外,积水还会进入到进气系统。
If the car is in the parking stall in the water, air inlet, exhaust muffler, have been flooded, there will be water intrusion of the exhaust pipe through the exhaust manifold, the water flow in the cylinder exhaust valve open combustion chamber. In addition, the water will enter the intake system.
维修方法:拆解发动机进气管和进气歧管以及火花塞,对发动机内部积水进行清理,用压缩空气将气缸燃烧室内的水吹干。
Maintenance method: disassemble the engine intake pipe and intake manifold and spark plug, clean the water inside the engine, and use compressed air to blow the water in the combustion chamber of the cylinder.
