from what i know, if 1 out of 4 cylinder break down(ie spark plug not working, or its cable or power), the car can still move, but lose like 50% power,


but 1 out of 3 cylinders break down, there is no chance it can still move

isnt that go EV directly solve the problem ?

sooner or later we need to go ev, carbon is the world's problem, the planet can live without us, we cannot live without the planet.

misfire and not fire at all maybe different ? i think misfire mean wrong timing, not the most efficient way to burn fuel, but not fire at all will break the crank's rotation cycle.

not the car is good, but the car is light, when you put more weight to the car, then the engine shaft, block, cylinder etc will have to push harder, more stress.

old car will have lesser component, ie maybe no aircon, no power steering, no auto braking, no auto gear, no airbag, no extra steel reinforcement, no power window, no remote control, no fog light, no fuel filter, seat belt auto retractor, no this and that. if you able to cut the weight of the car by half, the engine component will have lesser stress.

work as a foreman b4 for short amount of time(uncle's workshop), sometimes it doesnt really design's problem, like sometimes some ppl wash car, they wash engine, and they screw themselves up, sometimes ppl just itchy backside, DIY this and that, replace spark plug cable, replace spark plug. sometimes its hardware issue, like engine oil go into cylinder, spark plug distributor problem ... so it might not be design problem, low quality product also create problems.

really ? 2 cylinder engine for car ? im outdated.

thats cheating, thats still a 3 cylinder engine

like a cpu, a core sleeping doesnt mean the cpu has 1 lesser core.

technically battery waste compare to amount of carbon generated from fuel is nothing. also when we move towards EV, battery might not be completely wasted according to some report i read, cause battery degrade over time, but until 1 point, it will stable, stop degrading, maybe 30% or something(i forgot), its no longer suitable to be used in car(cause car need to be light, else waste power), so old battery will be removed and use elsewhere, like use in storing power for country.

power generated by solar and wind isnt stable, we cant generate solar power during the night, and wind power also cant do shit when no wind, so old EV batteries can be used for longer term storage.
