I saw similar topics but that did not explain my things... As we can see 4 stroke engine with 4 pistons
Is there any chance (only for test) to 'switch-off' two pistons? For this example I'm talking about spark plug/EFI disconnect of two pistons. Is there any chance so car with 4 pistons will works fine with only 2 pistons (as I say 2 pistons without EFI/Spark plug connect). I test it on my second car but disconnecting two pistons gives a result that car vibrated and wasnt 'stable' as normal (perhaps maybe there was knock detonation).
Can someone explain this in simple words and 'science' words?
