From choke to microcontroller in powertrain control module at intel
Combine a certain amount of fuel whit air, ignite the mixture and you
receive energy and residues of the reaction. We want to have as much as
possible energy and as less as possible residues. The fuel / air
mixture has to be "stoichiometric" (exact combined) . Before we ignite,
we compress the air/fuel. After the ignition we need time for the
reaction and for exporting the energy. The exact moment a sparkplug
starts the firing in a cylinder is important.
The conditions in and around an engine change. (throttle, rpm,
temperature of the engine, density of the air, accelerating or slowing
down)
The mechanical tools could adjust a few factors. (like the old choke)
Cost of fuel and environment factors obliged to do better. Electronics
came involved in the to organize the recipe for a better engine.
The [microcontroller] receives impute from car en environment
conditions. The microcontroller adjust fuel/air impute and ignition
point. The old ignition coil, spark distribution, and choke are gone.
Research will give more decisions to the "brain" of the microcontroller.
You know an important article that we do not link. We would love to hear from you.
