发动机进水再启动的后果
如果车辆在过水中熄火一定不要再次发动，再次发动有三种后果：r$http://img.miaomudu.com/2023/12/2023092745305|"http://img.miaomudu.com/2023/12/2023092745305F4http://img.miaomudu.com/2023/12/2023092745305t/http://img.miaomudu.com/2023/12/2023092745305h7http://img.miaomudu.com/2023/12/2023092745305^+http://img.miaomudu.com/2023/12/2023092745305P'http://img.miaomudu.com/2023/12/2023092745305T/http://img.miaomudu.com/2023/12/2023092745305M1http://img.miaomudu.com/2023/12/2023092745305r
一。就是还可以开，但空滤进水，发动机吸入空气后带入部分水到进气道形成水汽，水汽与汽油混合后充分燃烧，对发动机影响甚微。汽车维修技术网http://img.miaomudu.com/2023/12/2023092745305http://img.miaomudu.com/2023/12/2023092745305http://img.miaomudu.com/2023/12/2023092745305原创r$http://img.miaomudu.com/2023/12/2023092745305|"http://img.miaomudu.com/2023/12/2023092745305F4http://img.miaomudu.com/2023/12/2023092745305t/http://img.miaomudu.com/2023/12/2023092745305h7http://img.miaomudu.com/2023/12/2023092745305^+http://img.miaomudu.com/2023/12/2023092745305P'http://img.miaomudu.com/2023/12/2023092745305T/http://img.miaomudu.com/2023/12/2023092745305M1http://img.miaomudu.com/2023/12/2023092745305r
二。发动机内进入少部分水，到缸内后与机油，机油油品变差，含有水分的机油会加大发动机部件磨损，有可能以后车辆行驶发动机噪声及振动会变大。http://img.miaomudu.com/2023/12/2023092745305http://img.miaomudu.com/2023/12/2023092745305http://img.miaomudu.com/2023/12/2023092745305http://img.miaomudu.com/2023/12/2023092745305http://img.miaomudu.com/2023/12/2023092745305汽车维修技术网http://img.miaomudu.com/2023/12/2023092745305http://img.miaomudu.com/2023/12/2023092745305http://img.miaomudu.com/2023/12/2023092745305原创r$http://img.miaomudu.com/2023/12/2023092745305|"http://img.miaomudu.com/2023/12/2023092745305F4http://img.miaomudu.com/2023/12/2023092745305t/http://img.miaomudu.com/2023/12/2023092745305h7http://img.miaomudu.com/2023/12/2023092745305^+http://img.miaomudu.com/2023/12/2023092745305P'http://img.miaomudu.com/2023/12/2023092745305T/http://img.miaomudu.com/2023/12/2023092745305M1http://img.miaomudu.com/2023/12/2023092745305r
三。再次启动发动机发出声音几秒后再次熄火，而后启动多次一直启动不了，这种情况最严重，由于水不能被压缩，水进入气缸后发动机还是在高速工作，在时无法压缩水直接导致气门及连杆顶弯，活塞卡死，中缸磨损严重，曲轴弯曲，建议车主尽快把机油换掉。 有些车型的设计是进气道设计在叶子板上或者是机盖上，而且在水中行驶激起的水花也有高低，无法对比。r$http://img.miaomudu.com/2023/12/2023092745305|"http://img.miaomudu.com/2023/12/2023092745305F4http://img.miaomudu.com/2023/12/2023092745305t/http://img.miaomudu.com/2023/12/2023092745305h7http://img.miaomudu.com/2023/12/2023092745305^+http://img.miaomudu.com/2023/12/2023092745305P'http://img.miaomudu.com/2023/12/2023092745305T/http://img.miaomudu.com/2023/12/2023092745305M1http://img.miaomudu.com/2023/12/2023092745305r

发动机进水危害
车辆涉水后，水由进气歧管进入，由于水的不可压缩性，活塞运动行程将会变短从而导致发动机连杆弯曲或断裂，极端条件下会造成断裂连杆飞出击穿缸体。汽车在水中熄火的原因是分电器盖进水后使分电器丧失正常的点火功能，发动机空滤器滤芯浸水，导致进气阻力增大和燃烧室进水，火花塞无法点燃。如果这个时候重新启动发动机就很容易爆缸。http://img.miaomudu.com/2023/12/2023092745305r$http://img.miaomudu.com/2023/12/2023092745305|"http://img.miaomudu.com/2023/12/2023092745305F4http://img.miaomudu.com/2023/12/2023092745305t/http://img.miaomudu.com/2023/12/2023092745305h7http://img.miaomudu.com/2023/12/2023092745305^+http://img.miaomudu.com/2023/12/2023092745305P'http://img.miaomudu.com/2023/12/2023092745305T/http://img.miaomudu.com/2023/12/2023092745305M1http://img.miaomudu.com/2023/12/2023092745305r汽车维修技术网http://img.miaomudu.com/2023/12/2023092745305http://img.miaomudu.com/2023/12/2023092745305http://img.miaomudu.com/2023/12/2023092745305原创
发动机进水检测方法
1检查机油：
最简单的方法就是检查机油的颜色是否出现异常，如果机油变成乳白色，那就说明油箱或发动机中进水了。
2检查各个管道是否进水。r$http://img.miaomudu.com/2023/12/2023092745305|"http://img.miaomudu.com/2023/12/2023092745305F4http://img.miaomudu.com/2023/12/2023092745305t/http://img.miaomudu.com/2023/12/2023092745305h7http://img.miaomudu.com/2023/12/2023092745305^+http://img.miaomudu.com/2023/12/2023092745305P'http://img.miaomudu.com/2023/12/2023092745305T/http://img.miaomudu.com/2023/12/2023092745305M1http://img.miaomudu.com/2023/12/2023092745305r
逐一检查空滤及空滤下壳体有无较明显进水痕迹，并检查进气管及进气歧管内有无明显过水痕迹。
3检查火花塞汽车维修技术网http://img.miaomudu.com/2023/12/2023092745305http://img.miaomudu.com/2023/12/2023092745305http://img.miaomudu.com/2023/12/2023092745305原创
拆下各气缸火花塞并检查其是否潮湿，若潮湿则表明发动机有进水迹象。
4检查发动机气缸壁是否有积炭痕迹
发动机正常工作时，各缸活塞到达上止点的位置相同，气缸壁上止点位置清晰。当发动机进水后，由于水难以被压缩，导致活塞无法到达原有上止点位置，活塞运动行程变短，上止点位置会有较明显下移。汽车维修技术网http://img.miaomudu.com/2023/12/2023092745305http://img.miaomudu.com/2023/12/2023092745305http://img.miaomudu.com/2023/12/2023092745305原创

拆下火花塞，人为切断燃油供给系统和点火系统后用马达运转发动机，使进入发动机内部的水顺利排出。
同时检查车辆各系统油液状况，出现起沫、浑浊等现象应及时进行更换。汽车维修技术网http://img.miaomudu.com/2023/12/2023092745305http://img.miaomudu.com/2023/12/2023092745305http://img.miaomudu.com/2023/12/2023092745305原创
检测完毕后应用压缩空气清除发动机舱内部电器连接部件，防止水分积存在电器连接部位造成的腐蚀。
4 清理完毕后，进行车辆路试，以确定发动机在行驶过程中无异常噪音。如有明显行驶噪音，检查发动机轴承和旋转部件。但如果在拆下火花塞后启动时发动机没有转动，则说明发动机已经顶死，只能进行发动机大修处理。汽车维修技术网http://img.miaomudu.com/2023/12/2023092745305http://img.miaomudu.com/2023/12/2023092745305http://img.miaomudu.com/2023/12/2023092745305原创
