With temperatures rising recently, the phenomenon of spontaneous combustion occurred around the car brought to our attention, and the other fires, like the same car with the unpredictability of spontaneous combustion, so once the car spontaneous combustion, is likely to bring to the owners not economic loss alone.
Well, according to David tie rod end note, the spark plug operating temperature is very high. When the engine runs, the temperature of the spark plug insulator of the skirt is generally maintained at between 500 to 600 degrees Celsius. Temperature is too high or too low impact on the spark plug is not good. In the case of the spark plug temperature is too low, easy on the spark plug insulator deposition, eventually causing leakage that produce misfire phenomenon. If the spark plug operating temperature is too high, easily lead to early ignition and engine knock. Store staff will appear common faults summed up in two spark plugs. A serious erosion of spark plugs, spark plug another sediments.
Spark plug ablation
When the owners found a scar on top of or damage to the spark plug electrodes appear melting, ablation phenomena indicate that the spark plug has been destroyed, then you should replace the spark plug. During the replacement process owners can check the spark plug change disease as well as ablation of color.
Symptom 1: melting electrode and insulator white
Diagnosis: This phenomenon indicates that the combustion chamber temperature. It may be too much coke combustion chamber, causing the valve clearance is too small, and further lead to overheating or bad exhaust valve cooling devices work caused. In the spark plug according to the specified torque when tightening will cause the electrodes to melt the insulator is white phenomenon.
Symptom 2: The electrode and insulator knot round scar
Diagnosis: This indicates that early engine fuel, ignition timing may be premature or low gasoline octane, high heat value of the spark plugs and other reasons brought.
Symptom 3: Top cracked insulator
Diagnosis: Generally, knocking combustion is the main reason for broken insulators. The premature ignition timing, low-octane gasoline, the combustion chamber temperature is too high, it can cause engine knocking combustion.
Symptom 4: Insulation top with gray and black stripes
Diagnosis: This indicates that the spark plug is already streaked leak, the owner needs to unconditionally replaced with new parts.
There are deposits on the spark plug
Well, according to David tie rod end is understood that the spark plug insulator between the electrode tip and sometimes tainted sediments. Do not underestimate the owners of such deposits. This may cause severe engine is not working properly. After cleaning the spark plug, you can get the normal operation of the vehicle temporarily, but soon after there will be a similar situation. In fact, only one surface of the spark plug deposits phenomenon occurs, which may be a signal other mechanical parts of the vehicle in question.
Symptom 1: oily deposits on the spark plug
Diagnosis: When oil deposits appear on the spark plug, it means that oil has entered the combustion chamber. If you have oily deposits on the spark plug is only an individual, it may be caused by the valve stem seal damage. But if each cylinder spark plug such deposits are sticky, the performance of cylinder oil appeared jump. Generally, in the case of clogged air filter and ventilation, and prone to the phenomenon of jump cylinder oil.
Black deposits on the spark plug: Symptoms 2
Diagnosis: spark plug electrodes and internal black sediment, usually indicates that the cylinder gas mixture is too thick. Owners can increase the speed of the engine is running, and a few minutes in order to burn to stay in the top electrode layer of black soot layer.
Car flammable
Many people like to dress fancy car: Today, in the center console to put bottles of perfume; tomorrow, the next window filled with dolls; acquired and took seat covers replaced linen. However, these car move, to eventually become the root of the evil car.
Well Hung tie rod end, according to informed how to diagnose: Last summer, the car received a spontaneous combustion in Hangzhou German BMW X3. And most of the spontaneous combustion of different car, the car's ignition point is the back seat - according to maintenance personnel concluded that the owners put debris in the back seat, is an important contributing cause of the fire. Summer temperatures, car items at any time may become a dolphin "time bomb."
Treatment recipe: take advantage of the summer before the real arrival of the debris and clean your car: the perfume, dolls, ornaments, everywhere throw waste paper, do not often wear clothing, upholstery is easy to burn away, The more simple the better car. After all, this is a transportation tool, not a storage room.
