Whether the spark plug of a Petrol Car is working properly will directly affect the power, economy and purification of the Honda Car engine. How to simply and effectively judge the working status of the spark plug of a Petrol Car plays an important role.
1. Touch method
After starting the vehicle, if you feel that the Honda Car engine is idling unstable or shaking. Check whether there is any missing cylinder. First, stop the Honda Car engine and touch the insulating porcelain body of the Petrol Car spark plug cylinder by cylinder with your hands. If the temperature is significantly lower, it means that the spark plug of the Petrol Car in that cylinder is not working properly.
2. Appearance inspection
Check whether the spark plug insulator of Petrol Car is cracked or damaged, whether the electrode is loose or ablated, whether there is carbon deposits, grease, etc. in the center electrode and the porcelain cavity. The working condition of the spark plug of Petrol Car can be judged by these appearance phenomena.
3. Watch color method
The center electrode of a spark plug for a Petrol Car that is working properly should be reddish brown and the threaded end surface should be rust colored. The spark plugs of Petrol Car turn black due to carbon deposits, which is mostly caused by the poor working of the cylinder. If one cylinder does not work, the spark plugs of Petrol Car will be flooded with oil and water, that is, "cylinder flooding".
4. Fire break analysis method
This method can be further divided into high-voltage line method and short-circuit method. When the Honda Car engine is running at low speed, unplug the high-voltage wire of the cylinder and conduct a flameout test. If the engine speed of the Honda Car engine drops and the vehicle shakes, it indicates that the spark plug of the Petrol Car of this cylinder is working well; if there is no obvious change in operation, it indicates that the spark plug of the Petrol Car of this cylinder is working well. unusual. This method is not suitable for vehicles with high energy ignition.
