Can a Car Fuel Saver Actually Save Fuel?
2 Answers
Car fuel savers can indeed save fuel. There are several types of fuel savers, including electrolytic water oxygen-enhancing fuel savers, electronic turbo fuel savers, and cigarette lighter-type electronic fuel savers. An onboard car fuel saver is a compact gas-generating device that employs Faraday's electrolysis principle to produce hydrogen and oxygen from water. This introduces hydrogen energy as a new energy source into the car's fuel system while also providing oxygen to ensure complete combustion of hydrocarbon fuels. The hydrogen and oxygen mixture is directed into the car's air intake, where it enters the engine's combustion chamber along with air and mixes with the fuel-air mixture for explosive combustion. Hydrogen has a lower ignition point than gasoline, making it easier to ignite, and its flame propagation speed is five times faster than gasoline. The flame quenching gap is 0.06 seconds, only one-third of gasoline's 0.18 seconds, so adding hydrogen to the fuel-air mixture promotes more efficient combustion.
I've been driving for over a decade and have come across many so-called fuel-saving gadgets. There are several types of fuel savers on the market: electronic fuel-saving cards that plug into the cigarette lighter, magnetized fuel savers installed on fuel lines, and turbos that claim to optimize air intake. To be honest, reputable auto repair shops never install these for customers. The engine's fuel injection is precisely controlled by the ECU, and adding external devices might interfere with the wiring. If you really want to save fuel, it's better to maintain proper tire pressure and avoid sudden braking. Last time I cleaned the carbon deposits, my fuel consumption dropped by 0.5L. Those so-called fuel-saving miracles hardly save any money when tested, and they might even damage the oxygen sensor.
