The country does not advocate magnetic generators because magnetic generators need to be connected to a power source to generate electricity, which will cause electrical losses.
A magneto generator, or magneto generator, is a device that provides high-voltage pulses of electrical energy to the spark plug in the ignition system of a gasoline-powered internal combustion engine. Once used in all gasoline-powered cars, it was limited to lawn mowers, chainsaws, and internal combustion aircraft engines. The first person to come up with the idea of ??a high-voltage magnetic generator was Andre Boudeville (France), but capacitors were ignored in his design. Frederick Simms collaborated with Robert Bosch to develop the first usable high-voltage magnetic generator.
Magnetic generators were used by the Daimler Ph?nix Automobile Company in 1899 and were soon adopted by most automobiles to produce low-voltage and high-voltage magnetoelectric power until 1918. The low voltage, i.e. voltage, is used by the secondary coil to ignite the spark plug, and the high voltage, i.e., ignites the spark plug directly, similar to coil ignition, introduced by Bosch in 1903.
Aviation Applications
Because it does not require batteries or other forms of energy, the magneto generator is a compact and reliable self-sustaining ignition system, so it is still used in many general aviation applications today. . The aircraft engine of the magnetic power generation device is a typical double plug, that is, each cylinder has two spark plugs, and each plug has its own independent magnetic power generation system. This arrangement provides a backup in the event of damage to either magneto generator, and the twin sparks provide twin flame front points in the cylinder.
These two flame front points reduce the time required to complete fuel replenishment and ignition, so most of the fuel is already burning at a relatively low temperature and pressure. As combustion pressure rises in an individual cylinder, a lower octane fuel mixture can detonate at an inadvertent moment to ignite another flame front point on the other side of the cylinder, far away from the initial flame front point.
