Avg score: 61% Most missed: “Octane number is associated to ____________”
Ignition and Power Transmission topics include: IC engine ignition system, power transmission system, battery ignition system working principle, fuel supply system and its components, fuel quality, volatility, ignition quality and detonation. Here are some basics about ignition and power transmission: Ignition: The ignition system produces high voltage, which is applied between the electrodes. This breaks down the insulation between the electrodes, which causes a current to flow. This creates an electrical spark, which activates fuel particles between the electrodes. The spark also triggers... Show more
