Recently, a new Fuel Shark economizer (economizer) has appeared on the market. The manufacturer assuriy that the counter inserted in the cable's nest allows saving up to 30% of the fuel. Fuel economy is said to be achieved by a capacitor within an economizer, which first collects and accumulates electricity and then releases it back into the electricity grid when many powerful consumers are included.
In fact, inside the device is actually a small capacitor, there's nothing else there. The capacitor capacitor is capable and accumulating and producing electric energy, but the capacitor's capacitor is so small that it could not affect the fuel consumption of the vehicle in any way. Moreover, the capacitor is itself accumulating energy by taking it from the electric vehicle.
The function of the capacitor in the car is the battery. From the parallel installation of another battery, the effect will be more than that of the economizer. By the way, a capacitor installed in the economy of the economizer's shop is worth several dozens of rubles at the radio store.
