What happens if a small amount of water enters the engine intake?

If the air filter is found completely dry upon inspection, it indicates no signs of water entering the intake system. Below is relevant information about engines: 1. Introduction: An engine (Engine) is a machine capable of converting other forms of energy into mechanical energy. The first external combustion engine was invented by R. Stirling in the UK (Scotland) in 1816, later improved by Watt into the steam engine. 2. Application Scope: Engines can refer to both power generation devices and entire machines including power units (e.g., gasoline engines, aircraft engines). Types include internal combustion engines (e.g., gasoline engines), external combustion engines (e.g., Stirling engines, steam engines), gas turbines (used in racing cars), electric motors, etc.
I've encountered this situation many times during car repairs. A small amount of water entering the engine intake might sound insignificant, but the risks are actually quite serious. If water gets sucked into the cylinders, problems arise during the compression stroke. The mixture of water and air increases piston movement resistance, potentially bending the connecting rods or damaging the engine block. This usually happens after driving through puddles on rainy days or washing the car too aggressively. If only a small amount of water enters, the engine might shake, lose power, or even stall. If you suspect water ingress, immediately turn off the engine and don't attempt to restart it. Tow the car to a repair shop to check the air filter and pipes—cleaning them might solve the issue, otherwise, repairs can be costly. For prevention, I recommend avoiding deep water, checking the car after rain, and addressing any issues promptly to prevent corrosion or major engine overhauls in the long run.
