Can a Car Fuel Saver Actually Save Fuel?

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.

What are the functions of the three wires in the Excelle ignition coil?

The functions of the three wires in the Excelle ignition coil are: 1. Power supply wire: Provides voltage from the ignition switch and main relay; 2. Ground wire controlled by the engine ECU; 3. Control signal wire is the switching signal output from the ECU computer circuit board, which controls the ignition signal. The independent ignition system does not have high-voltage wires because the coil output is directly connected to the spark plug. The Excelle has a length of 4468mm, width of 1765mm, height of 1469mm, a wheelbase of 2611mm, front track of 1495mm, rear track of 1502mm, and a top speed of 170km/h.

Will mixing 95-octane gasoline with a car designed for 92-octane have any impact?

According to the "Motor Vehicle Gasoline" (GB17930-2016), using 95-octane gasoline in a car designed for 92-octane does have an impact. Long-term mixing of different octane ratings will affect the service life of the car's ignition system, fuel injectors, and spark plugs, leading to an earlier need for major repairs. The appropriate gasoline grade can be determined based on the engine's compression ratio. Cars with an engine compression ratio between 8.6-9.9 should use 92-octane gasoline, while those with a compression ratio between 10.0-11.5 should use 95-octane gasoline. If the compression ratio is even higher, 98-octane gasoline is recommended. However, with the application of new technologies, the compression ratio alone cannot determine the required gasoline grade. High compression ratio engines can be tuned to use lower-octane gasoline because other factors, such as ignition timing, turbocharging technology, and Atkinson cycle technology, also play a role. Generally, the higher the gasoline octane rating, the higher the octane number and the better the anti-knock performance. 92-octane gasoline contains 92% isooctane and 8% n-heptane, while 95-octane gasoline contains 95% isooctane and 5% n-heptane. According to "Motor Vehicle Gasoline" (GB17930-2016), occasional use of the wrong gasoline grade only requires switching back to the correct grade after consumption. However, long-term use of the wrong gasoline grade can have the following effects: Using a higher-octane gasoline in a car designed for a lower octane rating will not cause damage, but the increased octane number may alter the fuel's ignition point, leading to delayed combustion in the engine. This reduces the engine's power output and thermal efficiency, resulting in poorer performance. Using a lower-octane gasoline in a car designed for a higher octane rating can cause engine knocking. The significantly lower octane number reduces the fuel's ignition point, causing premature ignition during the compression stroke. If combustion occurs before the spark plug fires, resistance is created during the upward stroke, making the engine run very unstably. Mild knocking may only increase noise without obvious engine damage, but severe knocking indicates serious engine conditions, affecting driving stability and causing abnormal wear on pistons and cylinders, potentially leading to severe damage like cylinder scoring. Notes on gasoline selection: Choose gasoline with appropriate volatility based on the car's operating temperature. Gasoline with good volatility facilitates cold starts and ensures smooth engine warm-up. However, excessive volatility can easily cause vapor lock in the fuel lines, preventing the fuel pump from delivering gasoline properly and leading to engine stalling. Select gasoline based on its lead content.

Should Antifreeze Be Added in Summer?

Antifreeze should be added in summer. During summer, the engine operates at high temperatures, with normal working temperature limits often exceeding 100°C. Water boils at 100°C and is corrosive, which can lead to scale formation and affect cooling efficiency. Therefore, antifreeze is used to cool the engine. High-quality antifreeze coolant typically has a boiling point above 110°C, making it less likely to boil over in summer compared to water. The full name of antifreeze is antifreeze coolant, meaning it is a coolant with antifreeze properties. It is a specially formulated coolant containing additives, primarily used in liquid-cooled engine cooling systems. It provides functions such as preventing freezing in winter, boiling over in summer, and protecting against scale and corrosion throughout the year.
