Flowers stuffed with oily lubricant into the sediment is, the top insulator fragmentation may be low grade gasoline. In the maintenance of vehicles should pay more attention to the situation of spark plugs, spark plugs good performance can improve Vehicle Power Performance.
Typically, spark plug life to 15,000 km, long-lasting spark plug life is not more than 30,000 km. However, many owners of the spark plug all kinds of problems often arise not reach its normal service life.
In fact, the spark plug's operating temperature is very high. Normal operation of the engine, the spark plug insulator skirt keep the temperature generally between 500 to 600 degrees Celsius. Temperature is too high or too low on the impact of bad spark plug. In the case of low temperature spark plug, spark plug's insulator easy to coke, and eventually cause leakage and creates the phenomenon of lack of fire. If the spark plug operating temperature is too high, easily lead to early ignition and engine knock. Chery Automobile in training camp, the store staff will spark plugs, common faults summed up in two. A serious erosion for the spark plug, the other is the spark plug with sediment.
Spark ablation
When the owners discovered a scar on the top spark plug or damage, the electrode appears melting, ablation phenomenon, all show that the spark plug has been damaged, then you should replace the spark plugs. In the replacement process owners can check the spark plug erosion of disease as well as color changes.
Symptoms 1: electrode melting and white insulator
Diagnosis: This phenomenon shows that high temperature combustion chamber. This may be too much coke combustion chamber, resulting in valve clearance is too small, and further lead to overheating or cooling exhaust valve caused by poor work. In the spark plug according to the specified torque when tightening will result in electrode melting, the phenomenon of insulator is white.
Symptoms 2: electrodes and insulator end and round scar
Diagnosis: This indicates that as early as fuel engine, the ignition time may be premature or low octane gasoline, spark plugs, high calorific value caused by such factors.
Symptoms 3: insulator top fragmentation
Diagnosis: Generally speaking, the detonation combustion is the main reason for broken insulators. The ignition time early, low-octane gasoline, the combustion chamber temperature is too high, may lead to engine knock combustion.
Symptoms 4: insulation to the top with gray black stripes
Diagnosis: the emergence of such a stripe that has been leaking spark plug, owners need to replace parts without conditions.
Spark plug on a sediment
Spark plug insulator between the electrodes on top and sometimes glue deposits. Do not underestimate the owner of this sediment.
Serious this situation may cause the engine not working properly. In a clean spark plug, the vehicle can be normal operation for the time being, but soon after a similar situation occurs. In fact, the spark plug there is only a superficial sediment, which may be problems with vehicles other mechanical components of signal.
Symptoms 1: spark plugs have oil deposits
Diagnosis: When the spark plug appears when oil deposits, it shows that oil has entered the combustion chamber. If only individual spark plugs have oil deposits, it may be caused by valve rod oil seal damage. But if each cylinder of the spark plug sticking out of this sediment, it means that there jump up the oil cylinder. In general, the air filter and ventilation equipment congestion, the cylinder prone to leap up the oil phenomenon.
Symptoms 2: Spark plug with black sediment
Diagnosis: spark plug electrodes and the internal black deposit, usually indicates the cylinder gas mixture is too thick. Owners can increase the engine operating speed, and a few minutes to burn to stay in the top layer of black soot electrode layer.
