Why does smoke come out from the front of the car when driving through water?

[DePhoebe]

Reasons for smoke coming out from the front of the car after driving through water: 1. Normal combustion phenomenon: The exhaust pipe usually emits white smoke accompanied by liquid in the morning when the car is just started. This liquid is water, indicating good engine combustion. 2. Cylinder head gasket leakage: If you notice jerking while driving and white gas and water discharge from the exhaust pipe, along with a lack of water in the radiator and water overflow, it is most likely due to a leaking cylinder head gasket, which needs to be replaced. 3. Issues with the fuel injector or electronic control unit (ECU): Symptoms include jerking, reduced power, liquid discharge from the exhaust pipe, and high fuel consumption. The fault may lie in the fuel injector of a certain cylinder or the ECU, with the latter being less likely and the former more probable. 4. Excessive clearance in the engine's piston, cylinder liner, or piston rings: If the liquid from the exhaust pipe is black and sticky, accompanied by blue smoke, rapid oil consumption, and noticeably insufficient engine power, it indicates excessive clearance in the engine's piston, cylinder liner, or piston rings.
