Will the engine emit smoke when it blows up?

Engine blow-up will emit smoke, which is one of the factors causing engine smoke. The reasons and conditions for engine smoke are as follows: Black smoke from the exhaust pipe: Indicates that the air-fuel mixture is too rich and combustion is incomplete. Main causes: vehicle overload or engine overload; insufficient cylinder pressure; engine temperature too low, improper carburetor adjustment, clogged air filter; individual cylinders not working and delayed ignition. Blue smoke: Blue smoke from the exhaust pipe indicates a large amount of engine oil entering the cylinder without complete combustion. Removing the spark plug will reveal severe carbon deposits.
I remember last year my buddy's car had an engine seizure, what a scene that was! We were on a long-distance trip when suddenly thick blue-black smoke started pouring from the hood, accompanied by a pungent burnt smell. After stopping, we found engine oil leaking everywhere. When the mechanic opened up the engine, the piston was stuck in the cylinder with visible scoring on the cylinder walls. Engine seizure smoke is mainly caused by high temperatures leading to burning oil or coolant leakage, though it varies by vehicle. Once I saw a modified car spewing white smoke after seizure - that was from a ruptured radiator releasing steam. Bottom line: if you smell something odd or see smoke, shut off the engine immediately, otherwise repairs could cost more than a new car.
