Can Blocking the Exhaust Pipe Cause the Engine to Stall?

[IsabellaDella]

Blocking the exhaust pipe will cause the engine to stall. Reason for stalling: Combustion requires a mixture of fuel and air to form a combustible mixture. After each combustion, the exhaust gases are expelled through the exhaust pipe. If the exhaust pipe is blocked, the exhaust gases cannot be expelled from the vehicle, and at the same time, new combustible mixture cannot enter, causing the engine to stall and the vehicle to stop starting. Ignition method: When the engine starts, the mixture of air and gasoline is atomized (in a ratio of 14.7:1) and enters the cylinder. The piston, driven by the motor, compresses the mixture. The spark plug then ignites the mixture, causing an explosion that drives the engine to operate.
