What component in the ignition system steps up voltage?
What type of grease is used in spark plug boot ends to inhibit corrosion?
Most automobiles have a ______ volt DC battery.
In a distributor ignition system, what rotates under the distributor cap to send the high voltage to each spark plug wire?
Some electronic ignition systems eliminate the use of spark plug wires. What do they use to do this?
What would be a reasonable gap setting for a spark plug?
What would be a reasonable voltage at the tip of a spark plug?
What keeps track of piston and valve positions in the engine to efficiently time the spark?
Which of the following is NOT used to keep the crankshaft and camshaft synchronized?
What would be a common timing belt replacement interval?
What type of engine could result in a bent valve and piston damage from a timing component breaking?
Which of the following would NOT impact the life of a timing belt?
It is usually recommended to replace the whole timing belt system at the service interval. Which of the following is NOT one of those components commonly replaced at this interval?
In a coil, the ____________ winding is low voltage.
What is sometimes used on the threads of the spark plug?
Technician A says that most new cars have electronic ignition systems. Technician B says that crankshaft and camshaft sensors are used with electronic ignition systems. Who is correct?
Technician A says that most car batteries are 6 volts. Technician B says that about 50% of new cars have 6 volt systems while 50% have 12 volt systems. Who is correct?
Technician A says that all automobiles only have one ignition coil. Technician B says that some automobiles have one coil per cylinder. Who is correct?
Technician A says that diesel engines do not have spark plugs. Technician B says that diesel engines use two spark plugs for each cylinder due to the high energy content of the diesel fuel. Who is correct?
Technician A says that when changing the spark plug wires on a distributor ignition vehicle it is essential not to mix up the firing order. Technician B says that it is important to route the wires away from the exhaust manifold to prevent the wires from burning. Who is correct?
What is the purpose of the ignition system? Explain how the chemical energy of the battery ultimately becomes mechanical energy of motion to move the vehicle.
What are the main differences in distributor ignition engines and electronic ignition engines?
