How about the wrong calorific value?
What will happen if spark plug calorific value does not match properly. The first case is that the caloric value matching is higher than the original factory requirements, that is, if the heat dissipation is too good, the spark plug will not reach the normal working temperature, and over time it will produce carbon deposit at the spark plug electrode, and then affect the ignition efficiency of the engine.
On the contrary, if the calorific value of the spark plug is too low and the heat dissipation is not good, then when the spark plug high temperature accumulation is too much, the oil and gas mixture in the cylinder may not have time to be ignited by the spark plug electric shock, it has been ignited by the overheated spark plug body, which is often referred to as detonation.
As we all know, when the engine appears after the explosion, light power drop, heavy cylinder lava. So we choose spark plug, as far as possible to choose and their original factory calorific value of the same product. But if you are a keen driver, or brush a high-performance ECU, you can choose a higher calorific value of the spark plug, to prevent the engine in a long period of high-speed operation of the probability of detonation.
