WebbAir Forced Oil Forced. This has a good association with a heating element that is located at the top of the transformer tank and its primary function is to circulate hot air through the oil. This cooled oil circulates to the transformer tank. 4. Water Forced with Oil Forced. WebbIgnition System Basics. The four stroke gasoline engine relies upon an ignition system that can deliver an electric current across the spark plug gap. Air and fuel is drawn into a cylinder during the intake stroke. This mixture is then compressed to raise the temperature of the air fuel mixture. As the temperature increases, the fuel is vaporized.

WebbAn ignition Coil is (also called a spark coil) an induction coil which is used to increase the low voltage of the battery (12 Volt) to a very high voltage ( about 50,000 Volt) to produce a spark within the engine cylinder for the combustion of fuel. It is used in automobile ignition systems. We can also say that it is a short step-up transformer. WebbThe winding to which current is applied, which creates the magnetic field, is called the primary winding. The other windings are called secondary windings. Magnetic core. …
