The engine can start, but when the work is abnormal, when the black smoke is dripping, it may be the internal fire, carbon accumulation, and blocking of the engine. At this time, you can use an industrial endoscope to check. The mirror is called "Kong Tanzi" and is one of the five major tools of daily maintenance and routine inspection. The endoscope inspection is to master the internal conditions of the engine.
The endoscopic brand inspection can be checked in the inspection method of the internal conditions without breaking down the engine. The endoscope inspection is of great significance and value for safety and efficiency: First, it is intuitive, accurate and easy to run, and can detect the internal engine as soon as possible. The damage of the components is greatly conducive to excluding safety hazards in the bud stage; the second is that the endoscopic examination avoids the cost of decomposing engines and corresponding engine demolition, transportation, and unnecessary losses, saving maintenance costs.
Car endoscopy is small and light, easy to carry, easy to carry, easy operation, can detect various small parts such as car engines, and have clear images, high cost performance, handheld design, light weight, easy to carry. For some emergencies, fast and effective inspections are performed. Realize the rapid investigation of "finding problems → finding problems → solving problems" to improve work efficiency.
The engine can start, but the work is abnormal, the exhaust pipe is fascinated by black smoke, and it is accompanied by a jitter. The reason for the above failure is that the engine has a cylinder or a few cylinders of fire.
Start the engine, use a screw rotation to carry the spark plug -in nuts one by one, and observe the operating conditions of the engine. If the engine speed does not change after the iron is carried, it indicates that the cylinder does not work; if the engine speed decreases significantly after the iron is carried, then the engine speed is significantly reduced, then the speed of the engine is significantly reduced. It shows that the cylinder work is normal, and then further check according to the situation.
1. A tank does not work. The high -voltage division of this cylinder spark plug should be taken to make it about 4mm from the spark plug, connect the ignition switch, and observe the jumping situation. There is fire, indicating that the spark plugs should be cleared, and the carbon accumulation should be removed; no fire, indicating that the high -voltage segmentation or the distribution equipment fails, and it should be maintained or replaced.
2. Two cylinders do not work. Check whether the order of ignition should be correct, check and correct.
3. Several cylinders do not work at the same time. The central high -voltage line of the electrical cover should be removed for a jumping experiment. If the jumping fire is normal, it means that the high -voltage line power supply is normal. The fault should be maintained or replaced on the electrical cover, the high -voltage segmentation, or the spark plug. Essence You can clean the power -off cams first, and then check the electric container and ignition coil.
The application of industrial endoscopes in the engine field makes the inspection and maintenance of the engine faster and efficient. If you have relevant needs, please contact Shenzhen Micro Vehicle Optoelectronics Technology Co., Ltd. to consult.
