It is very important to choose the right spark plugs according to the type and parameters of your car engine. Properly selected and correctly installed candles guarantee high performance and uninterrupted operation of the engine.
Iridium candles, platinum candles – DENSO
Starting from the moment of the invention of electric ignition by the German brilliant engineer Robert Bosch, the search for new and new ways to increase the efficiency of engines is not stopped. In particular, engineering geniuses continue to look for optimal material for electrodes, change the number of electrodes in candles (to increase the stability of the detonation of the fuel mixture) and even try and experience candles of various sizes, hoping to achieve the most productivity of the engine with the optimal ratio of cost and operational resource of light lights. At the moment, you can find candles with 2, 3 and 4 electrodes in the public domain.
In the first cars, collapsible candles were used, which could be cleaned at any time. This was undoubtedly convenient, but the craving for simplification of all the components of the car led to the appearance of whole (non -collapsible) candles.
The device of almost all the spark plugs in general is the same. The candle usually consists of an electrode, an insulator (made of high -strength ceramic material), a case and a contact pin, which is often covered with an attack. The candle housing is also equipped with a thread for screwing into the candle well on the cylinder head, and a hexagon, which simplifies its installation and tightening with a hexagonal key.
Features and differences of platinum and iridium candles
Important!
The first iridium candles were patented in 1997 by DENSO, which, by the way, is one of the main suppliers of electronic components for the production of Toyota cars. The manufacture of an electrode from Irididia will significantly increase the service life of such candles (according to the manufacturer’s statement, the service life of such candles reaches 200,000 km).
In addition, the use of iridium allows you to make the central electrode much thinner. The use of such candles is most justified for small engines operating at high speeds.
Today, practical characteristics as in iridium candles have candles with a platinum electrode. However, the price of such candles can be significantly higher. I advise you to see GDE-KUPIT-I-USTANOVIT-car radio for every taste.
