Study Notes
Ignition Systems
- The spark is adjusted to be generated when the piston is near the top dead center.
Types of Ignition Systems
- Battery ignition system or coil ignition system
- Magneto ignition system
- Electronic Ignition System
Battery Ignition System or Coil Ignition System
- Consists of battery, ignition switch, ignition coil, distributor, condenser, contact breaker, spark plugs, and Rb.ballast resistor
- The conventional coil-ignition system is breaker-triggered
- Battery provides current to the ignition system
- Ignition switch turns the engine on or off
- Ignition coil steps up battery voltage to generate spark
- Distributor regulates spark in each spark plug in the correct sequence
- Spark plug generates the actual spark for fuel combustion
Construction of Battery Ignition System
- Consists of primary and secondary circuits or windings
- Primary circuit: battery, primary winding of ignition coil, condenser, and contact breaker
- Secondary circuit: secondary winding of ignition coil, distributor, and spark plugs
- Voltage depends on the number of turns in each coil
Operation Principles of Ignition System
- Current flows through primary circuit, then to primary winding, and lastly to contact breaker
- Contact breaker opens, generating a high voltage (10,000 to 20,000 volts) in the primary winding section
- High voltage then passes to the distributor
Electronic Ignition System
- Fully controlled electronically
- Used in aircraft engines, bikes, motorcycles, and cars
- Generates high voltage spark that can burn lean mixtures, providing better economy and lower emissions
- Components: transistors, sensors, and electric pulses
Starting System
- Includes battery, starter motor, solenoid, ignition switch, and starter relay
- Components:
- Battery: supplies current to starter motor, ignition system, and acts as electrical reservoir
- Ignition switch: distributes electrical current to where it is needed
- Neutral safety switch: prevents vehicle from starting while in gear
