What brand is ACDelco spark plug?
1 Answers
ACDelco is a brand of spark plugs under the Delco brand, which is an independent aftermarket business brand owned by General Motors in the United States. Below is the relevant introduction about spark plugs: 1. Working principle: Under the effect of high voltage, the air between the center electrode and the side electrode of the spark plug will rapidly ionize, forming positively charged ions and negatively charged free electrons. When the voltage between the electrodes reaches a certain value, the number of ions and electrons in the gas increases like an avalanche, causing the air to lose its insulating properties, forming a discharge channel in the gap, and resulting in a 'breakdown' phenomenon. 2. Characteristics: The standard for spark plugs usually uses the heat value to characterize the thermal properties of the spark plug. The heat value of a spark plug indicates the balance ability of the spark plug's insulator skirt to absorb and dissipate heat. The higher the heat value, the stronger the balance ability of heat absorption and dissipation. Therefore, hot-type spark plugs have a low heat value, while cold-type spark plugs have a high heat value. Generally, engines with high power and large compression ratios use cold-type spark plugs with high heat values; conversely, engines with low power and small compression ratios use hot-type spark plugs with low heat values.
