allocator ceiling androtorsare responsible for for passing the voltage from theignitioncoils to the engine ’s cylinders to ignite the fuel - melodic phrase mixture inside and power the engine . The spiral connect forthwith to the rotor , and the rotor spins inside the allocator pileus . When the rotor ’s tip passes a contact on the cylinder , a high - potential difference pulse rate travels from the coil to the cylinder via the rotor coil . That pulse jumps the little spread between contact and rotor and moves on to the sparkle plug wire , finally igniting the Dame Muriel Spark plug on the piston chamber . Because of all the high - potential drop natural process , the rotor coil and cap have to be replace relatively frequently . They wear out out easy .
The distributor cap and rotor are part of the firing system , which has to work in concert with the rest of the engine in Holy Order to fire up the fuel at the proper time . The musical theme is to maximize the output of the expanding gases in the engine by lighting them so that they produce heat and the fuel turn to eat up . The exhaust fumes increase the press in the piston chamber and promote the Walter Piston down . The theme is to create as much pressure as possible inside the piston chamber , thereby maximizing torsion and office . Plus , the more efficient the piston chamber are , the better the car ’s gasoline mileage will be .
Therefore , the real grab to the volute - distributor - cylinder system is time . Since there ’s a short holdup between when the light is created and when it ignites the mixture in the cylinder , the spark has to happen before the piston reaches the top of its stroke . That way , by the time the twinkle arcs its means across the gap between the rotor and the cylinder , the piston will just reach the top of the solidus and the pressure will be able to build up as it descend into its business leader cam stroke .
