Engine failure classifications First, failure of cylinder and tile burning. When there is too much carbon between the piston and the cylinder, or insufficient oil, and too much dirt in the configuration system, the piston will be damaged when heated and expanded. And burning tile is generally in the system when problems, such as insufficient oil, configuration clearance is too small, oil plug is not impassable and so on, resulting in difficult start-up startup, flameout or smoke phenomenon. Maintenance measures for such troubles are to replace the appropriate piston according to different vehicle types and the corresponding engine-like cylinder to alleviate the damage of the cylinder. When the Bush is burnt, it needs to be scraped to adjust the degree of shaft and Bush configuration, and then, bearing dressing can be solved. Feilong Jiangli will share other kind of failure. Second, fuel injection pump problem. If the injection advance angle praseodymium error. If the valve is not sealed or the parts are damaged, the fuel injection pump will be replaced, or if the fuel supply advance device is damaged, the spring may be broken, the spring supporting plate may be worn out, the counterweight block will be stuck and replaced.
Tiffany Yuan posted a topic in Introductions & General TalksEngine failures can be roughly divided into the following: 1. The main reason of engine starting lag is the lack of battery energy. The engine speed is inversely proportional to the starter power. The higher the engine speed, the less starter power. In the case of starter power shortage, the engine starting will be very difficult. Of course, when the engine joint is loose, the tubing is broken and the base cushion is not strict, the piston is damaged, air and oil seepage, or oil seepage, pipeline blockage, sealing is not good, cylinder pressure is too low and so on, will also affect the normal operation of the starter to solve the maintenance measures is to replace the battery first. If the problem still exists, it is necessary to replace the oil pipes, connectors and liners of the engine as soon as possible, and then discharge the filters and sewage from the pipes to keep them open or replace the piston rings with better wear resistance to make the cylinder pressure normal. Feilong Jiangli will share other kind of failure. 2. Premature or late fuel injection causes abnormal oil. People who drive cars often have this experience, such as the cylinder when the fuel supply "when" sound or dull "ringing" sound, which is really premature fuel injection and the performance of the spring, in this case the fuel supply is either too large or insufficient, resulting in engine speed and dynamic abnormality. The maintenance strategy is to loosen the two screws of the fuel injection pump coupling after the car starts, so that the flywheel pair on the fuel meter is on the corresponding degree line on the rotating disc of the fuel injection pump, and at the same time, to align the rear knuckle up by the timing so-called calibration line, which corresponds to the strength of the full pedal on the throttle, so that the fuel supply is stable until the normal power.
