How to set the ignition on a four-stroke engine?

Each of the car enthusiasts knows firsthand what the wrong moment of ignition is. For the driver this is a constant problem with starting the engine, with loss of power, as well as with increased fuel consumption. For the unit itself, such malfunctions can end very badly, especially if the moment of ignition is selected a little earlier than it should be.

In this article, we will look at how to set the ignition on a contact and non-contact system. The first from the very beginning of production is set on the classics, the second appeared at the beginning of the twenty-first century. It immediately gained popularity among car owners, as it differs from the previous reliability and resource, as well as the best electrical characteristics, on which the sparking in the combustion chamber directly depends.

On how to put the ignition on a car, you can tell in brief. The process will be discussed below. The fact is that four-stroke engines are quite picky at the moment, but despite this, putting the ignition on the same Soviet or foreign car is not so difficult as putting the ignition on Izh Jupiter 5. The latter on each cylinder, of which two, has its own , A separate contact ignition system, each of which requires adjustment.

Now directly about the procedure itself. Naturally, you can get to the nearest service station where this will be done with a stroboscope, but it costs money, and this device is not for every motorist, so we will consider the simplest method that requires minimum efforts, tools and knowledge.

First of all, you need to calculate the compression stroke in the first cylinder. You have to plug a candle hole with a cotton wool, after which smoothly rotate the crankshaft for a ratchet. As soon as it flies, we turn on, until the marks on the pulley coincide and on the ebb of the front cover. In some cars there are three marks, each of which corresponds to AI-80, AI-92 and AI-95 in the course of rotation. In fact, how to put the ignition on a particular car, there are a lot of manuals, you just need to spend some time searching the Internet.

Let's return to our procedure. Crankshaft installation along the middle mark will set the ignition advance 5 degrees. While the crankshaft will "turn them on", ignition will already occur in the combustion chamber. For each brand of gasoline, the time for this is different, hence the lead angle also changes.

The need to install the ignition may occur after repair, as well as after negligent use of the car. The ignition can go off by itself, if the engine creates an increased vibration. Then we will have to ask ourselves again: "How to set the ignition?". Vaz 2106 has the same system as described above, so there will be no problems with it. Now, when the piston is at the top dead center, you can install the ignition distributor in the desired position.

To do this, remove it from the drive, and then install the runner by an external contact in the direction of contact of the first cylinder on the lid. Thus, at the end of the compression stroke in the first cylinder, a spark will flow into it, which will ignite the mixture. Well, now questions about how to put the ignition, should not arise. After the completion of this procedure, it is necessary to start the engine, after which it is necessary to make a more accurate adjustment on the heated unit.
