Is this a purely ecological innovation or just a ‘’trick’’ to reduce the emissions produced by heat engines?

An advantage for the environment and a disadvantage for the vehicle? The theories surrounding Start and Stop Technology are contrasting.
It is basically a mechanism projected to interrupt the functioning of the heat engine when the car is stationary or out-of-gear, halting so fuel delivery, the ignition starts again when the car begins moving and the clutch is pressed. It only shuts the engine, meeting zero-emission capability, yet the electric circuit remains active and everything connected to it does so.

This is seen as 100% eco-innovation because it reduces fuel consumption and vehicle emissions. In fact, the idea behind it is to reduce the amount of time your engine spends idling. What this really is, as Rete Riparo suggests, vehicle manufacturers hide behind fuel emission normative: Start and Stop Technology permits heat engines to remain between an emission standard limit. Any heat engine, petrol or diesel it is, function on the basis of a combustion chamber in where once fuel and air are insert and after a compression process, all the remaining gases are eliminated and the cycle begins.

Later in the years, systems do not only filter, but also try to depurate harming gaseous pollutants. This is not enough. In order to pollution be reduced to the minimum, it is necessary that the heat engine is completely shut. This is where the Start and Stop Technology comes to play. As mentioned earlier, it intervenes stopping the combustion engine. On one hand, this technology brings many advantages, especially environment-wise. On the other hand, it is also necessary to consider the wearing-out of an engine: higher number of Stop-Start cycles lead to increased engine wear unless steps are taken to prevent it.
As everything, also this technology has its pros and cons. The only solution is to establish what causes the minor harm to your vehicle.
