How Ignition Systems Work ?
Every action has a reaction.On your car’s engine is same thing when we are talking about the ignition system.Is mixture of air and fuel, we need spark to ignite this mixture.The spark fire the mixture is the action, that what cause an explosion for the engine to start running is the reaction.
The ignition system is ensemble of components to create the ignition.The components ignition is the coil,a distributor,a distributor cup,a rotor,plugs wires and spark plugs.There are two types of the ignition system, the modern car today using an ECU, I already talk about the ECU before Engine Control Unit. In the other hand the old ignition system type is using points and condenser.I am going to explain to you the function for each ignition system components.
– 1. Ignition Coil
The ignition coil collect the power from the battery and transformed to spark.We have two coils in the ignition coil and there are on the top of each other that what we called winding .Is the primary winding collect the power and create a spark. The secondary winding is to send the spark to the distributor.The malfunction of these winding can cause bad starting,misfires,and short spark plug life. Complete testing of the coil requires an ohmmeter.The primary and secondary winding resistance can be checked and compared .During testing the LT and HT wires must be disconnected from the coil.To test the primary winding connect the ohmmeter between the two LT terminals.To test the secondary winding connect the ohmmeter between the negative terminal and the HT terminal.

-2. Distributor, Distributor Cap, And Rotor
The distributor explain it self.The function of the distributor is to collect the spark from the coil,and distribute it to the engine following the order of the firing engine to the spark, using the spark plugs wires.In the distributor you find the rotor, and on the top of the distributor is distributor cup. Some old type of the distributor take point and condenser. Find your car distributor from this store online.
– 3. Spark Plugs And Wires
The functioning of the spark plugs is vital for the correct running and efficiency of the engine.It is essential that the plugs fitted are appropriate for the engine.The spark plug gap is considerable importance.If it is too small or too large , the size of the spark and efficiency will be seriously impaired.The gap of spark plug is set with a feeler gauge, and then bend open or close,the outer plug electrode until the correct gap is achieve.For the spark plug receive spark we use spark plugs wires.
