What is the spark plug model for Tianjin Honda 90 motorcycle?
1 Answers
Tianjin Honda 90 spark plug model is A7TC. The spark plug is a crucial component in the ignition system of gasoline engines. It introduces high voltage into the combustion chamber and generates a spark by jumping across the electrode gap, thereby igniting the combustible air-fuel mixture in the cylinder. Under high voltage, the air between the spark plug's center electrode and side electrode rapidly ionizes, forming positively charged ions and negatively charged free electrons. When the voltage between the electrodes reaches a certain level, the number of ions and electrons in the gas increases like an avalanche, causing the air to lose its insulating properties. A discharge channel forms in the gap, resulting in a "breakdown" phenomenon. At this point, the gas becomes a luminous body, known as a "spark." Along with thermal expansion, a "crackling" sound is also produced. The temperature of this electric spark can reach 2000-3000°C, which is sufficient to ignite the air-fuel mixture in the cylinder's combustion chamber.
