Currently Delco is known as the component that generates the spark current through a synchronized break and then distributes it to the corresponding cylinder.

-It is powered by a battery and the current rises through a coil, outside the "Delco" itself.

-We have seen this in surface vehicles such as cars, trucks, boats, etc.

-In aviation, except for some sporadic cases, ignition by Delco takes place in a somewhat different way.

-Instead of a battery, a dynamo was installed on the engine.

-This in turn requires a voltage regulator.

-For safety there is a small battery of about 8 Volts in parallel with the generator.

-On top of the cylinders and taking advantage of the cam shaft, which is already rotating at the right speed, there are distributors with their breakers, including a voltage booster.

-And there is a switch in the cockpit controlled by the pilot.

-Below we see some generators in important examples of top brand engines.

"Lorraine-Dietrich, with Delco"

-Very similar is the assembly of the American Liberty engine. With an almost identical layout compared to the above mentioned Lorraine engine.

"American Liberty engine with Delco"

-The components are identically identified with the letters G and D like the previous example.

“The 24-cylinder Lorraine-Dietrich engine”

-This engine requires two spark-generators (G) and four distributors (D).

-Observe the beautiful support with the "Cross of Lorraine" (Croix de Lorraine) signs on its structure.
