Search for Ignition leads :

Ignition system serves to ignite the working mixture in the cylinders of petrol car engines. There are several requirements to the ignition system. For example, it must provide a spark in the right cylinder in accordance with the order of the cylinders. One more requirement is to provide a timely moment of ignition.

Spark must also occur during the ignition according to the best timing angle of the engine, depending on the speed and load on it, under the given conditions. The spark must have enough ignition energy. The amount of energy required for reliable ignition of the working mixture is caused by several factors: density, composition and temperature of the mixture. But the main condition for the ignition system is its reliability that is continuous sparking ensuring.

Malfunction of the ignition system leads to malfunctions during start-up and when the engine is operating. These are irregularity of the engine operation or its stoppage when passing the sparking in cylinder or several cylinders, difficulty or impossibility of starting the engine, as well as malfunction of other electronic systems in the car. In modern engines there is installed one coil per one single plug. And the coil is made in the form of caps, combining high-voltage transformer with a power control key. This eliminates distributor and high-voltage wires use.

If you have a need to buy the ignition coil, you can do it in our online store. To do this you just need to order the required spare part without leaving your home or office. And we will deliver your order in short terms to any convenient place for you. In addition to ignition system we offer you to buy ignition coil, ignition module and other spare car parts.

What is necessary to know about ignition cables replacement: lifetime limits, common defects and their signs, tips and recommendations

High-voltage cables of the ignition system have no specified lifetime limit, they should be replaced upon necessity.

The most common defects of the cables are connected with damaged current-conducting core and insulation. Also parts stop working properly due to oxidised or thermally damaged contacts.

Necessity of high-voltage ignition cables replacement can be noticed by unstable engine operation, troubled start in moist weather and increased fuel consumption. The engine stalls, its power lowers, jerks are noticeable when pressing accelerator pedal.

Diagnostics of the ignition cables should be performed at a service station. Specialists will measure resistance of the components with the help of a multimeter. To do so, the high-voltage cable is disconnected from the ignition coil and the spark plug, then connected to the unit contacts. Received data is compared with allowable values, provided by the manufacturer.

Replacement of the parts is also performed at a service station. During replacement of the ignition cables kit, tips are removed from the spark plug isolators, moving the cables aside. Then, defective wires are sequentially disconnected from the ignition distributor cover, and new parts are installed.
