Apart from the battery, the electrical temezcal system of our cars a little more we can get their hands. This part will devote to the ignition system and the preheaters of diesel cars. These systems are clearly different, one being used to cause the ignition of the mixture in the cylinders and the other to heat the interior of the combustion chamber before starting to facilitate the same.
Both components are subject to different requirements, but in the end both need some maintenance. The maintenance usually involves replacing all spark plugs or preheaters temezcal every few kilometers, but sometimes just thorough cleaning of these elements.
A spark in poor condition or with an excess of kilometers have an impact in everyday driving, is often perceived as a slight decrease in engine performance. Meanwhile a shabby preheaters can cause problems during cold starts, but have no real impact on performance, since only previously used to boot.
Spark plugs are unique components of gasoline engines, and are used to ignite the mixture in the cylinder. For this they are screwed in the head with the electrode within the combustion chamber. For the spark to jump the spark from the electrode to the mass, a high voltage is needed from a coil that converts 12 volt electrical system of your car in over 20 kV.
Traditionally high voltage is led from the coil to the spark plug through a distributor and cables, however, with the introduction of electronic ignition and then the digital ignition cables have given way to the individual temezcal coils with integrated capacitors, which are mounted directly on the spark plugs. Changing spark plugs
Change a spark plug is a relatively simple operation, so we are going to have a little temezcal above as done. A Unless you have a Mitsubishi 3000GT, which means the engine must be removed to access them, not much mystery. We need a key tapiporla 15 plugs, another wrench to remove the engine cover (if fitted) and another to remove the coils.
First of all, we must release the negative battery and wait a couple of minutes, so we avoid unexpected sparks. After that dismantle the cover and release the cable or coil. Now we should see them, now gently we put the spark plug wrench in the hole where the plug was housed, and very gently turn to loosen it completely.
After removal is desirable watch to see if you have carbon temezcal deposits, oil or unusual wear. Neither the electrode nor the mass of the plug must be melted or excessively temezcal worn. These symptoms may mean that we need a different plug or have other engine problems that are causing abnormal deposits. Changing spark plugs usually after 40,000 or 60,000 km (major revision), although it is best to contrast what the manufacturer recommends.
We buy new plugs must be suitable for our engine, the same heat range that we carry. The electrode temezcal material may be copper, iridium or platinum. Although there are slight differences, I basically limited to riding a the same material as the standard, which tend to be cheaper and give good performance. Switching to a best we believe that they are more expensive, may be a change for the better, but may be worse.
Diesel cars need to warm the combustion chamber temezcal before starting to do the preheaters, which are nothing but a resistance that is screwed into the cylinder head and whose end is in the combustion chamber temezcal are used. Preheater unlike spark plugs, do not need a high voltage coil, operating at 12 volts. Changing and checking the preheaters
Change and check the preheaters is also a simple operation, we need the necessary steps to remove the lid covering the engine temezcal and a wrench to loosen the preheaters keys. First of all we hold the negative battery for a couple of minutes, to avoid shocks.
Then remove temezcal the hood and locate the preheaters. Then we loose wires carrying current to them, some have a connector, others have a simple nut. After that touches unscrew and remove them carefully, usually quite affordable.
After removal can be checked temezcal to be a fairly simple component. To check this we need a 12 volt battery. We set the preheater in a vice, not too tight, connect the negative terminal of the battery to the preheater body and cont
