"Increase the fuse capacity?"
Nakamori Ginzo (Kid) frowned:
"Can this really make a moving car explode?"
"Can."
Sakaki looked at the cigarette between his fingers and said softly:
"Older Nissans used open metal fuel tanks and line-type fuses mounted on the positive battery terminal."
"It allows a certain amount of current to pass through. If it exceeds the rated current by 1 times, it will fuse within 1 second to protect the circuit and electrical appliances."
"That is, the fuse."
Everyone looked at each other.
Of course they know what a fuse is, but...
What does this have to do with the explosion?
“What would happen if someone replaced the wire fuse with copper wire?”
Sakaki lowered his eyes and spoke calmly:
"Copper wire won't melt..."
"At this time, just connect a copper wire, wrap a cotton ball around the top, and insert it into the metal fuel tank to create a negative pole..."
"The faster the car goes, the faster the piston moves, which generates high-voltage electric sparks to supply the ignition system. After the power consumption increases, the battery and the generator will work together to supply power to the ignition system."
"Wait a moment!"
Conan looked up and said doubtfully:
"If the copper wire is connected to the battery..."
"When Kiichiro Numabuchi started the car, a large amount of current would surge out of the battery. The car should have exploded immediately!"
"No, because it's an open tank, there's air in it."
Sakaki Makoto shook his head:
"In a stationary oil tank, the oil level is calm. As long as the cotton thread is above the oil level, the cotton wrapped around the copper wire will not burn even if electricity is applied."
"But when the vehicle is running vigorously, the oil level will inevitably begin to fluctuate..."
"At this point, as long as the battery starts working and high voltage current flows, the explosion will naturally occur."
