What is Transistor Controlled Ignition?
Instead of using a distributor to determine when each cylinder fires, the car's ECU uses camshaft and crankshaft position sensors, along with MAP/MAF and throttle position sensors to determine the optimum time to fire each cylinder for the most power/lowest emissions. As opposed to fixed advance (vacuum or centrifugal) employed in distributors. Transistor Controlled Ignition is commonly referred to as Coil On Plug (COP), Transistor Controlled Ignition is just marketing bumpf to make it sound awesome.

Typical of most newer engines, the coil either is used to fire two plugs simutaneously, or each plug will have it's own coil. We will try the first. A four cylinder engine has a typical firing order of 1342. If you split the running mates you end up with 14,& 32. The engine will have two coils, each… with two high tension wires coming out and going to the repective plugs. So, that means one coil pack will operate cylinders 1&4, while the other will go to 3&2. The other method with the plugs having it's own coil, the primary wires should be in a loom together at different lengths, and it would be hard to get them confused. I solved the problem by looking how the leads are connected on a Peugeot 205. This has the same transistorised distributor. The firing order is 1 3 4 2 Where Plug 1 is on the RHS looking into the engine from the front and Plug 4 is on the LHS. Plug 1 connects to the Top LH Connector on the distributor (again looking from the front) Plug 2 connects to the Bottom LHS connector. Plug 3 connects to the bottom RH connector and Plug 4 connects to the top RH connector. (MORE)

Answer . It takes the place of the 'points' that used to be in the distributor, collapsing the coil's field at a precise time, dissipating voltage from the coil to the spark plugs and firing the air fuel mixture in the engine's cmbustion chambers.

Answer . the little gray box on top the a.c. compressor or by the radiator.
A transistor is an electronic component known as a semiconductor.The first practical transistor was invented in 1947 and became analternative to vacuum tubes (valves) and relays. Early transistorswere made with germanium but silicon is used almost universally insemiconductor manufacturing. A single …transistor is a fewmillimetres wide and tall and has three terminals. It works bytransferring a high resistance input to a lower resistance output.The transfer of resistance gave rise to the name trans - istor. Atransistor will generate a large change in current for a giveninput or a large change in voltage. There are numerous ways to usethem and the applications and science of the transistor can fillmany books - too complex to discuss in detail in this answer.Transistors are good amplifiers and are found in radios, musicequipment, video systems in their role as an amplifier. They arealso very efficient switches and because they will switch from lowto high, are common in binary circuits. The transistor is the basisof all digital computers. A modern CPU chip in a computer isactually made of many billions of transistors inside the integratedcircuit. A typical computer will have trillions of transistors intotal. For further reading, take a look for basic electronicstutorials. All of them will have detailed descriptions of the way atransistor works and demonstrate the more common applications. (MORE)

Answer Transistors are semiconductor devices which can be used as switches (to turn on and off an electrical signal or current path) and also as a signal amplifier in a circuit. There are two broad types of transistors BJT (Bipolar Junction Transistor) and FET (Field Effect Transistors). - Neer…aj Sharma A transistor is a silicon device with 3 leads, emiter, collector, and base. It is used both as a fast switching device and for signal amplification. It is said to be "saturated" when maximum current is flowing and "cutoff" when no current is flowing from the emiter to the collector. It takes a difference of approx. .7 volts between the emiter and base to turn it "on". Good switch but actually inferior in sound quality to its predicessor, the "Thermionic" or good ole vacuum tube. If you don't believe me, listen to a guitarist play through both a transistor and vacuum tube guitar amp. You will be quite amazed!!! For signal amplification the input signal goes into the base and the amplified output signal is taken at the collector with the transistor operating, or biased, between cutoff and saturation. It would be normally biased in between cutoff and saturation for the signal to be "linear" or non distorted. The signal at the collector will be inverted (180 phase shift) with respect to the input signal. There are other applications where the output is taken at the emiter where the signal is not inverted (in phase) with respect to the input signal. This configuration, generally, has no gain or has what is called "unity gain". Sometimes you see this when separate stages need to be impedance matched for maximum efficiency. The transistor is first "biased" or configured for a specific amount of gain and the output signal is taken at the collector with a higher amplitude than the input at the base. A transistor is a semiconductor device used to amplify and switch electronic signals and electrical power . It is composed of semiconductor material with at least three terminals for connection to an external circuit. A voltage or current applied to one pair of the transistor's terminals changes the current through another pair of terminals. Because the controlled (output) power can be higher than the controlling (input) power, a transistor can amplify a signal. Today, some transistors are packaged individually, but many more are found embedded in integrated circuits . The transistor is the fundamental building block of modern electronic devices, and is ubiquitous in modern electronic systems. Following its development in 1947 by John Bardeen , Walter Brattain , and William Shockley, the transistor revolutionized the field of electronics, and paved the way for smaller and cheaper radios, calculators, and computers, among other things. The transistor is on the list of IEEE milestones in electronics, and the inventors were jointly awarded the 1956 Nobel Prize in Physics for their achievement. (MORE)
You may be out of luck with this check. I have a 93 with a non-turbo 1.6 and due to a non-start senario I knew the ign. module was the culprit. Being a master Ford/GM tech. and former automotive parts sales man at a local NAPA store, I took the unit out and took to every parts store around as well a…s a ford dealer. No one has a way to check this module to see if it is bad. Being that the car was made in Australia the local Ford dealers never botherd catering to soulving any of it's primary problems. If you suspect the module is the problem due to a no-start...the module is not cheap and trial and error may be the only course of action...good luck. my son had the same problem & he could not find a module we replaced the whole distributor & it started but the dist. cost him over 300 dollars.

The "brain" of the ignition system, the Ignition control module controls the ignition timing and strength, as directed by the main computer. It can be located in a variety of places, but it can normally be found underneath the hood.
A device such as a radio can be said to be transistorized when earlier designs are replaced by designs in which transistors replace vacuum tubes.
It sends the proper signal to the ecu to allow certain curcuits to close to allow power to the acc, on and run positions with the key.
That depends on the car. Most are under the hood in a electronics module box.
Answer: . The 1994 Dodge Intrepids (3.3 and 3.5L engines) don't have a separate ignition module. The Powertrain Control Module (PCM) controls the functions of an ignition module. The PCM is located under the hood on the engine. It's held in place by a stud bolt and push pin. There's a "60-pin" co…nnector attached to the back of the PCM. If you're removing the PCM, you'll need to remove the stud bolt and push pin, and unplug the 60-way connector. (MORE)
The ignition control module on a 2.5L Fiero is changed by removingthe lower steering column panel, disconnecting the wiring harness,and unbolting the module. A new module is then bolted in and thewires reattached. I owned one of these and never saw a ignition box of any kind inthis location. The 19…85 to 1988 had distributorless ignition. Themodule is held to the bracket by the ignition coil screws. Tochange remove the 4 screws holding coils on, seperate the coilsfrom the module, unplug the module, depending on year 1 or twoharnes plugs. To assemble reverse process. 1984n the module lives under the rotor inside the distributor capand has two wires from the harnes and two that run to the pick upcoil.

It is basically an electronic "thing" that has three terminals. Lets say E (emitter), B (base) and C (collector). Lets say we connect C to positive of a battery and E to negative (or ground). As long as we keep some current at B , we'll have current flowing from C to E . Basically it…s some device that controls current on one side from current on another side. the former being larger in magnitude than the later. ANSWER: Is a semiconductor voltage amplifier (MORE)
Yes the ignition control module is a part of the distributor or d.i.s system intruduced in the late 70's by some manufactuers.
If you have a 350 with HEI (electronic ignition), it will be under the distributor cap, under the rotor, bolted with two small bolts to the landing of the distributor. Hope that helps.
Depending on how the transistor is biased and various othercircuits connected to it, a transistor acts as an amplifier and/orswitch. When acting as an amplifier the circuit containing the transistorcan do things like transmit or receive radio signals, performanalog mathematical calculations, generat…e waveforms, etc. When acting as a switch the circuit containing the transistor cando things like turn on/off a light, turn on/off a motor, performdigital logic or mathematical operations, fetch and decode computerinstructions, etc. Exactly what a transistor can do is really only limited by thesystem requirements and the designer's imagination as to how tomeet those requirements. There are several different types of transistors: bipolar junctiontransistors (BJTs), field effect transistors (FETs), unijunctiontransistors (UJTs), programmable unijunction transistors (PUJTs),spacitors, surface barrier transistors (SBTs), tetrode transistors(TTs), point contact transistors (PCTs), etc. (MORE)
A FET is just a material either N or P whereby a restriction is applied by a field volts impressed on the material as restricting the current flow or allow the current flow
It does not have one. It don't even have a distributor in it. You either have a bad cam sensor or crank sensor if it's not firing.
The ignition control module acts like the coil and sends the sparks to the correct cylinder when the computer tells it to.
You can do it yourself by going to troubleshootmyvehicle.com(the author is correct) or take it to oreilly auto parts or autozone. They both will test it for you...Take it to both places..a second opinion never hurts...good luck....

for a BJT to amplify we give input signal if suppose we use BJT in CE configuration input is given at Emitter-Base junction and output is taken at Collector base junction the input voltage increases or decreases the forward bias of the E-B junction affecting a change in the base current and we know… that collector current is a function of base current collector current also varies so by selectively changing the base current we can effectively change the collector current (MORE)
if your Honda has a v-tech the igniton control should be on the left side of the engine and if it don't then look on the far right of the engine and it should be where the spark pulgs are.
When using an arduino controlling a relay- why are resistors used with the transistor to activate the relay coil?
Because without the resistor, there would be a short from the base to ground, and sometihng would smoke.
It may be possible for an auto parts store to test it for you ( depending on type of vehicle). Call around and tell them the make and model of your vehicle. You will have to remove it ( disconnect your battery first ) and take it to them.
It sends a power to the starter relay/solenoid to engauge the starter. Know that the ignition switch is not what you put the key in and turn. That is the lock assembly. The ignition switch is located lower down on the steering column.
ignition module is located under the distributor, where the spark plugs come out to go to the spark plugs, remove 6 bolts that hold the 3 capped distributor on, unplug the wires from both ends of module, 3 plugs, lift module out, nothing holds it in after distributor is removed, plug new module in, …replace distributor. (MORE)
No. think of the transistor as the ignition coil on conventional ignition systems. It's what sends the spark to the spark plugs. The only thing really controling the speed is you... These cars tack really high. And you don't really have to worry about top end because you'll never really get a chance… to go that fast. So if your trying to mess with the govenor then you really don't need to. (MORE)
1) Voltage overload due to bad ground connections, or possibly other open or short connections. 2) Heat. Lack of proper heat sink compound (when mounting certain types) or lack of proper ventilation. 3) poor quality replacement parts.
The Ignition Control Module on the 4 cyl models is located under the Distributor cap.
The control module is located under the hood, sometimes inside distributor,or mounted on outside of distributor, or as a distibutor-less module with coil packs mounted on top or on passengerside fender behind headlight area. All depends on make of vehicle.
Because the operation of the transistor is determined by the current at the base. the principle equations of BJT operation are: I c = h*I b ,and I e =I b +I c thus device operation is controlled by the input current.
base Umm.... Device current results from forward biasing of the emitter-base junction. Thus you can: 1. hold the emitter constant and apply control to the base (most common), or 2. hold the base constant and apply control to the emitter (common/grounded base circuit, mostly used at hig…h/very high frequencies).

It is mounted on a BRACKET that holds the coil in place. It's flat with electric wires pluged into it. It is on the top left rear side of the engine.
Yes. The ratio of collector current and base current is DC gain, also known as beta, or hFe.
All BJT transistors are. You have the base input current and collector output current with a gain factor. FETs are voltage controlled resistances.
The electronic ignition control module on an automobile is installed by first locating the unit at the top of the engine. The wiring harness is then disconnected from the original unit an a new module put in its place.
When bipolar junction transistor(BJT) is operated under proper biasing large current flows through the BJT,thus it is called current operated device.
