Easy To Build CDI (1)
Easy to Build of CDI – We know, the principle advantage of a CDI (Capacitor Discharge Ignition) System is the ability to present a superior spark to the air/fuel mixture inside the combustion chamber, thus maximizing burn efficiency. The easiest way to build CDI, we must understand to know Basic Ignition System. Look This below Schematic Diagram of CDI System.
We start from pickup coil, when the tooth approaches a pickup coil, the magnetic field in the pickup coil changes, and an AC signal voltage is induced in the sensor coil/ pickup coil. This signal transmit to control the SCR with resistor and capacitor (parallel R1 and C1 for adjust the advance timing), SCR turn ON and OFF if receive this signal and make the voltage an anode the SCR turn ON and OFF appropriate input the SCR. This cycle make the capacitor (C2) charge and discharge to switches an ignition coil and make the field magnetic and produce high voltage to secondary ignition coil, this high voltage supply to spark plug.
Component this Circuit:
R1=22K Ohm
R2=1K Ohm
C1=3,3uF/50V
C2=1 uF/400V
D1,2,3=IN4007
SCR=2P4M
The simple ignition just produce results like above picture, the linear advance with RPM Engine, we can not adjust the advance timing, because we use the parallel R and C for adjust advance timing for this CDI ignition. We can be adjust the advance timing with Advance Module like below picture.
The purpose advance module as this circuit is adjuster advance timing, with change delay of time charge and discharge of capacitor C2, if the positive signal come to the module, the module switch ON the SCR, and delay some time to switch OFF. This function to get accurate the ignition timing appropriate RPM of Engine. We get optimum power of engine (Acceleration and top speed can be maximum) if the the timing ignition is accurate, acceleration begin 1500RPM, top speed over 2500RPM, not misfire and knocking, this make to damage the engine. The flexible and easy to adjust the advance timing, we must to use The Programmable Ignition System or read in HERE to Learn more or jump to Easy to Build CDI (2).

woowww…nice info friend
ur very2 expert in automotive
Nice blogg shell we echange our links, plz link me and drop a msg to me i will add you friend thank you
Nice blogg shell we echange our links, plz link me and drop a msg to me i will add you friend thank you
makin mantefff brow
good idea of easy to build ignition
How about Easy to built CDI (2)? The link cannot click or maybe still under progress?
Every standard CDI have a cutt-off at certain RPM. How we can adjust or remove the cutt-off to get better or no limit RPM? How about the circuit? Thanksss
[...] next to more article… NB: We not sale or product this CDI, this CDI product Bintang Racing Team (BRT), we just open metode to learn more about of CDI Racing to support of Easy to build CDI. [...]
I don’t understand about it, but
oUgh..i’m not UnDersTand..keEp SpiriTs,GuyS!
thanks bro
wew, thanks ur info
tersub posting sob…thank informasinya
wah inget waktu SMP dulu pernah belajar kayak begini
mantap
BLOG walking and dropping smile
here…care to link exchange?
cool bro!
good night bro
very interesting tips, i read first
thanks for tutorial and tips
thanks this article and support me at Pulsa Host to Host for fast to index by google(Cepat Terindex),so Kerja Keras to selles and Bisnis Pulsa.
thanks bro Bisnis Pulsa GSP
istilah IG untuk inputnya apa itu????
IG= Ignition
Engine cut off
otto thk’s bray….@otto : rajin bikin CDI jg?
skrg sdh g lg, dulu thn 2007 msh kenceng2 na experimen cdi motor n mobil, DIS juga he he
@otto : blh bljr bnyk tentang CDI ga???sy mau belajar bt mtr dl….pnya kontak yg bs dihubungi ga????kbetulan sy dr bdg.thank’s ya bro otto.
for big firing on your engines,use our ignition booster
