wiring up ignition systems

The first ignition system i had to wire up was a system using afunction generator to trigger the module,it also had a coil and spark plug in the circuit so sparkplug can fire.i build the circuit like it was described to do

The thing i found hardest about this one was wiring up the igniter because it has 5 pins and i had to sort out where the go.After doin sum research on google i found the specifications and i found that only four pins are used because the 5th pin is only a misfire detection that i dont need the pins i did use was triger,coil,power and earth.In the picture above the red wire goes to the power,the black wire goes to the earth,the yellow one goes to the coil and the green one goes to triger. it has a function generator to triger the module.After setting it up and turned it on and it was working like it should.

 

The second system i wired up was  a system using a distributor to trigger the module.It has a coil and spark plug in the circuit so spark plug can fire.

in this system I stil used a igniter but i wired in a distributer to triger it instead of using a function generator as shown on the first circuit.The igniter pack is wired up the same as in the first circuit but  wiv the distrubetor in the place of the function generator.After i wired it up i turned the distributor and it sparked at the sparkplug wich meens it works as it should and the exersice was a succes.i used a 12v power supply to make the circuit work

The third circuit I had to build was a system with a wasted spark ignition system using the function generator to triger the module

In this circuit I stil used the igniter but with using a wasted spark setup instead of a coil set up the igniter is stil wired up the same way but with the wires that go to the coil is now goin to the wasted spark with two sparkplugs wired up.I stil used the function generator aswel.The wasted spark has 4 plugs to wire up

1-bat+ 2-bat- 3-triger 4-triger

the reason it has two triger is because it has one for each coil so I only had to wire up one of the two.

after I wired this circuit up and had the tutor check it i turned it on and it was working perfectly as it should didnt hav to change anything

The 4ht circuit I had to wire up was a coil over ignition system.This system uses a function generator to trigger the modue it also had a coil and sparkplug so sparkplug can fire.

In this circuit I did not use the igniter anymore.The reason for this is because it has its own built in igniter so dose not need one to work.

testing ignition coils

the first thing i did in this task is get two coil and get there specifications.Getting secification for the coils is easy you just have to find the part number that would be on the coil then eneter this numer in google and it will give you a website to get all the secifications of.I did this and got:
coil 1:

no:  cic32r
voltage:  12v
primary:  1.8 ohm
secondary: 8 to 9 ohm

coil 2:

no:  cic31
voltage:  12v
primary:  3to4 ohm
secondary  7to8 ohm

After finding the specifications of these coils i tested them and found:
coil1:
primary: 1.8 ohm
secondary: 0 ohm
earth leakage test:no

coil2:
primary: 3.3 ohm
secondary: 9.75 ohm
earth leakage test: no

coil one is not serviceable because at secondary there was no resistance. this shows that this coil is faulty.
coil two is servicable because it meets specifications or is close enough to the specifications.

Next test was testing a wasted spark coil pack
testing the three coils:
coil 1:
secondary: 12.67 kohm
primary: 1.2 ohm
coil2:
secondary:12.73 kohm
primary: 1.2 ohm
coil3:
secondary:12.75 kohm
primary: 1.1 ohm

Next thing to test was ballast resistotrs. first i had to get the specifications
ballast resistor 1:
no:BR2
ohm spec: 1.1ohm
ballast resistor 2:
no:BR3
ohm spec: 1.7ohm

measured resistance:
ballast resistor no1: 0.9ohm
ballast resistor no2: 1.7ohm
both of these ballast resistors are serviceable
Testing the ballast restors was done with a mulltimeter set on ohms the black terminal coming out of com goes onto the -of the ballast and the red terminal coming out of v/ohm goes on the + of the ballast.

Next task was measuring current draw and voltage drop.To do this i had to wire up a ballast resistor in series with a coil primary windings.To test this i had to connect an ameter in series and get the current draw.I did this and got a result of 5.4A. Next i calculated the voltage drop across the coil by using the formula AxR=V from ohms law:
4x1.3=7.02 the 4 is the amprege in the circuit the 1.3 is the resistance in there circuit therefor:
calculated voltage drop across the coil is 7.02v
measured voltage drop across the coil is 4.7v
I calculated the voltage drop across the ballast resistor:
5.4x1.7=9.18 same formula as before 5.4=amprege and 1.7=resistance therefor:
calculate voltage drop across the ballast resistor is 9.18v
measured voltage drop across the ballast resistor is 6.83v
my calculated voltage did not equal my measured voltage the reason for this was my coil was on for to long and if coil are left on for to long they lose power.

injector testing

in this task i had to get 4 injectors to test.the first test was testing the resistance first thing was geting the manufacturers specifications the way i did this was on the injector there are some numbers wich is the part number,i put the number in at google and it came up with specifications and it show me that the resistance specification is 13.5 for two of same ones and 13.8 for other two same ones.the next test was the winding resistance measure with a multimeter result was 13ohm for the one and 14 for the other.the next test i had to do was a earth leakage test and and wasnt earth leaking.I had to wire up the injector to check if it clicks if it does it works.The first thing to do is to get a wire from the positive of the supply and a wire from the negative that has to go onto the plug that has two pins one for positive and one for negative.There are some other engine problems that could give same result as an injector not firing for example sparkplug faulty or the distrubuter wires are shorting.After testing the injectors we had to clean them.When removing fuel injectors from engine you have to make sure to remove residual presure from the system before removal.We used a injector cleaner to clean them its a machine you put the injectors in top of cleaner wire them up,then there is options for u how to clean them like flushing them.It can also pulse like it would in a car and u can change the rpm for faster pulse.The specification for the injector flow rate of my injector was 192cc per minute.
I tested all four my injectors and got a result of:
spray patern:all four good
flow rate:all four good
injector leakage:all four good
none of these injectors require atention

The injector cleaner we used is similar to the one above.I got this image of a webside called gut motorsport http://www.gutmotorsport.net/
after all the tests i did on my injectors i found that all the injectors i used is in good condition and reuseable.
