Direct Ignition System

The high generated vltaje is divided according to the relative pressure of the cylinders. Cylinder that is on the compression stroke will require and consume more discharge voltage in comparison with the twinned cylinder that is on the exhaust stroke. This is because an electric spark leads better in high-pressure environment, as it is a cylinder in compression, in comparison with a low pressure environment, such as a cylinder in the career of exhaust that is close to atmospheric pressure, so in the latter case voltage to produce spark is much smaller. When we compare them against ignition with distributor systems, the total voltage required for electronic distributorless ignitions is virtually the same. The loss of voltage derived from the space between the rotor and the terminal within a distributor CAP, is replaced with the loss of voltage in the cylinder that goes in the career of exhaust in a simultaneous system of Distributorless ignition. Direct ignition (Direct Ignition System DIS) system to the DIS have evolved, there have been changes in the function and location of the ignition module. The independent is on DIS, there may be a turn-on for all cylinders module or a unique module for each cylinder.

It depends on the design, but the electrical behavior is equal. DIS there is a module for all coils in simultaneous ignitions. The following illustration gives an overview of the different types used in different engines. The following DIS uses an ignition module for all coils. The SCE signal is deactivated when the STE signal is activated. They are contrary. The coils on this system using a high voltage diode for quick cuts of the secondary circuits.

If you suspect a faulty coil, swap it with another another cylinder coil. On simultaneous DIS this system uses three signals STE to activate the coils according to the sequence of the firing order. When a coil is activated, the STE is disables. I hope this information you have been useful. If you want to see more, Monterrey.
