The Engine Cylinder Not Working

The engine is the power source and core of the car. If the engine is "sick", it will show some symptoms, misfiring of an engine is just one of the faults. The most common symptom of insufficient cylinders is a noticeable drop in power. At this time, the vehicle is like a body without a soul, so it is very important to know the danger of a lack of cylinders.

The lack of an engine cylinder is one of the aftermarket engine blocks that do not work. A lack of cylinders will shorten the service life of lubricating oil, and it is prone to dead fire, high fuel consumption, black smoke, and weak acceleration. Idling is like an asthmatic, dying vehicle. After a few minutes, there will be signs of flameout and death.

Main cause: The ignition system and fuel injection system are faulty. It should be noted that when the engine lacks one cylinder, both cylinders can be started, but the power performance drops significantly. According to research, as long as one spark plug is out of the cylinder, the fuel consumption may increase by 10%-15%, the power will decrease by 18%-35%, the CO and HC content in the exhaust gas will double, and the power performance will decrease.

As for the problem of carbon deposits in the engine, due to the current oil products, there is no pollution after combustion. Often, these combustion products are likely to cause engine carbon buildup. Just like "being sick and catching a cold", individual cylinders ("nostrils") of the engine with poor breathing at this time will be blocked, and the intake air volume will be insufficient to ignite the mixture, resulting in a lack of cylinders. In addition, these carbon deposits will cause premature combustion and deflagration, detonation, detonation, and abnormal wear, and irregular cleaning will easily affect the service life of the engine.

Judgment method for engine lack of cylinder: observe whether the body shakes violently when idling, and then observe whether there is obvious intermittent airflow in the exhaust pipe. The exhaust pipe shakes violently, with a "chug" or "plop" sound. During driving, when the speed is lower than 2000 rpm, the body shakes violently, the acceleration is weak, and the symptoms improve slightly after increasing the speed. The test method to determine which cylinder is missing. You can short-circuit the spark plug with a screwdriver, or pull out the cylinder tube of the split cylinder for an ignition test. If there is no obvious change in the operation of the engine, the cylinder is not working.
