How do car gas systems work?

The gas is managed by intelligent electronics included in the gas system components every step of the way from the tank to the engine.

Sometimes when you accelerate while the engine is still cold, the fuel type immediately switches from gas to petrol. Surely you already know it is no accident. This happens when the engine receives too large a  dose of cold fuel. This is detected by the reducer, which is equipped with a  housing temperature sensor. It immediately sends a signal to the controller, which reacts by switching the fuel type to petrol. Only once the engine reaches the right temperature will the controller switch the system back to using gas.

It is worth noting that despite the engine start process automatically using petrol by default, all ALEX systems also feature an emergency start function that allows you to start your engine using gas in case of a  failure in the petrol system.
