AUT 240 quiz 1 || 100% Accurate Solutions.
degrees of crankshaft for a full 4 cylce correct answers 720 degrees or 2 revolutions
degrees of camshaft for a full 4 cycle correct answers 360 or 1 revolution
what is the best way to determine a problem related to compression correct answers cylinder
leakage test
when does spark occur correct answers 10-20 degrees before TDC
during the combustion stroke when is the burn over correct answers 15-20 degrees after TDC
vacuum in the intake at idle should be correct answers 18-20 in of Hg
what happens to vacuum at WOT correct answers quick drop then recover
vacuum at deceleration correct answers highest point of vacuum
what happens if there is no O2 reading correct answers if no O2 reading is present the car will
go into open loop
why is fuel in direct fuel injection squirted into the cylinder at such high pressures correct
answers because it has to go against the pressure of combustion and so that it doesn't boil
why is a test light sometimes more beneficial than a DMM correct answers a DMM only
requires a very small amount of amperage to obtain a good reading, but a test light requires
more, especially if it is incandescent
input impedance correct answers working resistance
in a parallel circuit amperage is? correct answers added together
why is a 5V reference benficial correct answers if you do not have 5V present, then the car
will die or not run/ cranking- B+ drops considerably so 5V is safe
what is reference low correct answers a ground used for the sensor which goes to the PCM
what is the generic setting on a scan tool correct answers a setting where only actual values
will be displayed, otherwise the computer will substitute values
what does the oxygen sensor measure correct answers oxygen
what is the purpose of the O2 heater correct answers to heat up the sensor so it can be faster
as to producing readings and controlling fuel, generates its own voltage
what determines octane correct answers resistance to detonation (high is more resistant)
knock sensors are used to correct answers adjust timing
