Gap the plug to .054".1Fill In the BlanksUsing your notes, and the handout, answer the following questions.Engine _____________ and _____________ are the two major factors that effect engine timing.ATDC = ______________________________________________________BTDC = ______________________________________________________True or False (advanced = spark happens sooner, retarded = happens later)Another reason is that as rpm increases, there is less and less TIME for the ignited mixture flame to completely burn, so the spark must occur EARLIER in the process...again, this as rpm Increases. Common usage has EARLIER meaning ADVANCED, LATER meaning RETARDED._________ If timing moves from BTDC 50deg to BTDC 40 Deg, timing is “advanced”._________ If timing moves from ATDC 10deg to BTDC 10 Deg, timing is “retarded”._________ If timing moves from BTDC 10deg to ATDC 10 Deg, timing is “retarded”._________ If timing moves from ATDC 10deg to ATDC 15 Deg, timing is “advanced”.Additional items such as __________________, ________________, and _______________ are monitored to provide better spark accuracy as these conditions change.Answer “Advance or retard” for the questions below:When engine vacuum is low the spark must ___________________________When engine speed is low the spark must ___________________________The faster the engine goes the spark must ___________________________When is engine vacuum low? Open or closed throttle? ___________________Go to www.howstuffworks.com , and then the automotive section (under the hood) to answer the followingpicture.
