Chapter 8 Ignition System Fundamentals 157 Copyright by Goodheart-Willcox Co., Inc. 4. List fi ve types of distributorless ignition system. 5. In a waste spark ignition system, there is one ignition coil for every _____ cylinders. (A) two (B) three (C) four (D) Any of the above, depending on the engine manufacturer. 6. A(n) _____ ignition system does not have secondary wires or conductor strips rather, the coil assembly is directly mounted on the spark plug. 7. A dual coil-on-plug system has two _____ per cylinder. (A) coils (B) plugs (C) plug wires (D) valves 8. Primary wiring is _____ in size compared to battery cables. 9. In the primary circuit, a resistor is used to: (A) increase voltage in the circuit. (B) increase current in the circuit. (C) decrease voltage in the circuit. (D) decrease resistance in the circuit. 10. Defi ne ignition timing. 11. Th e ignition timing advance system: (A) adjusts the spark earlier (advances) for starting the engine. (B) increases (advances) the voltage at the spark plug gap to improve combustion. (C) adjusts the voltage for high engine speeds. (D) adjusts the spark earlier (advances) or later (retards) in relation to engine speed and load to prevent spark knock. 12. Th e secondary ignition circuit: (A) distributes the high-voltage current. (B) times the high-voltage current. (C) creates the spark. (D) Both A and C. 13. Th e _____ is an ignition device that provides a gap in the combustion chamber across which the high- voltage current in the secondary circuit can jump. 14. Th e misfi re monitor: (A) is an internal function of the ECM. (B) can detect a misfi re within 200 crankshaft revolutions. (C) fulfi lls a requirement of the OBD II protocol. (D) All of the above. 15. An ion-sensing ignition system uses the spark plug as an ion sensor to determine whether _____ has occurred. ASE-Type Questions—Chapter 8 1. All of the following are part of a photoelectric sensor assembly, except: (A) LED. (B) magnet. (C) photodiode. (D) shutter. 2. Technician A says that the pickup coil rotates with the distributor shaft . Technician B says that the Hall- eff ect switch is stationary on all types of systems. Who is correct? (A) A only. (B) B only. (C) Both A and B. (D) Neither A nor B. 3. Technician A says that a distributorless ignition system may have more than one coil. Technician B says that a distributorless ignition system may have more than one pickup. Who is correct? (A) A only. (B) B only. (C) Both A and B. (D) Neither A nor B. 4. Self-induction occurs in the _____ coil windings. (A) primary (B) secondary (C) Both A and B. (D) Neither A nor B.
