Iv used those cheap lighters that use a quick spark to ignite the gas, but after a couple weeks they die out. How are the ones in engines so reliable and last for so long?
Furthermore, how can they fire at JUST the right time, thousands of times a second?
Thanks in advance

No moving parts and 100+ years of development means it’s pretty much as good as it gets in terms of anything that will just work.
Lighters. They have worked good enough for 100+ years, they don’t need the precision so no one puts the time in anymore. Loads of moving parts comparatively, people will only pay pennies and no one is in that mad of a rush that they need to fire first time every time.
