The working principle of the electronic salute is that the atomized gasoline or gas is controlled to enter the combustion chamber through a solenoid valve, and then ignited by a high-voltage and high-energy discharge pulse that can generate 500,000 volts, thereby generating deflagration and giving off a strong and loud sound of guns. The electronic salute was fired by nine seamless pure steel pipes, each with a diameter of 7.5cm and a length of1.1m. Before each launch, pour a small amount of gasoline (about a small handleless wine cup) into each steel tube, then turn on the oxygen cylinder switch, introduce oxygen into the steel tube base, and then turn on the battery switch. When you need to shoot, press the screw switch, and you can freely control whether you can play sound continuously according to the screw switch. There is also a car salute, which sounds similar to other salutes. Is it a barrel? The head is sealed, the other end is open, there is a small hole near the sealed end, gas is injected into it, the gas injection pipe is removed, and then the gas injection hole is ignited with an electronic ignition device, and a salute is sounded. There are also electronic igniters in spark plugs or electronic lighters.
