Importance of checking ignition circuit
Objectives: At the end of this lesson you shall be able to
• explain Importance of checking ignition circuit.
Checking the ignition circuit is important because it ensures that the engine’s spark plugs receive the necessary
voltage to ignite the fuel-air mixture. Without proper ignition, the engine will not start or may run poorly, leading
possible damage. Regular checks help maintain optimal engine performance, reliability and fuel efficiency.
1 Reliable Engine Starting: Engine starting reliably, especially in various weather conditions such as cold or
rain.
2 Optimum Engine Performance: It contributes to maintaining engine performance and output power.
3 Fuel Efficiency: Proper ignition timing improves fuel efficiency, which saves fuel costs.
4 Emission Control: Helps reduce harmful emissions by providing efficient combustion.
5 Preventing Engine Damage: Early detection and resolution of ignition problems helps prevent damage to
engine components.
6 Safety: A properly functioning ignition system ensures safe vehicle operation.
7 Smooth Engine Idle: Helps keep engine running steady and smooth while reducing vibration and noise.
8 Acceleration Response: Ensures responsive acceleration by providing consistent spark timing.
9 Diagnostic Aid: Checking the ignition circuit can help diagnose other engine performance problems.
10 Long Term Reliability: Regular checks contribute to engine reliability and longevity.
