इंजन के अंदर पानी जाने से क्या-क्या नुक्सान होता है? | What happens when an engine gets water in it?

A specific type of automotive engine damage occurs when water enters the engine and is compressed in one or more cylinders. Water and fuel (petrol or diesel) have different densities and do not mix with each other. Engine components are designed to function with a specific type of fuel. Fuel is not only used for combustion but also acts as a lubricant and coolant in components such as the injectors and fuel pump.
If significant amounts of water get into the intake of a car engine and are sucked into the cylinders, then you get a phenomenon calls “hydro-locking”. That happens when the piston tries to compress essentially incompressible water. It will lead to severe engine damage, and very probably bend the connecting rods.
Water in the oil won’t cause immediate breaking of parts as hydro locking one will, but a lot of water will cause the oil to become a brownish/whitish sludge that is not good at lubricating your engine. It won’t run long like that, and you are doing significant damage. It’s best to not run one as soon as you realize the oil is contaminated, and drain the oil/water mix out and re-fill. You might even need to do this a few times to be sure to get all the water out.
1. Rust in the fuel tank:
Since water and fuel do not mix with each other and because water is denser than fuel, water rests at the bottom of the fuel tank. The prolonged presence of water will cause rust there. The rusting is accelerated if there are ridges and sharp edges in the fuel tank. Rust can also extend to other parts of the fuel line.
2. Fuel Injector Failure:
Today's petrol engines (MPFI engines) make use of injectors to supply fuel into the combustion chamber rather than a carburettor. The pore size of these injectors is so designed that they spray the right amount of fuel under all conditions. The injector efficiency also depends on the density of the fuel. Water,being denser than petrol, cannot be sprayed as easily as fuel and will produce stresses in the injector. This might lead to injector failure. In diesel engines, although fuel filters can remove foreign elements to an extent, high amount of water content would cause severe problems. The reason is that diesel fuel injectors work at higher spraying pressures.
3. Fuel Pump Failure:
The motor which runs to pump fuel from the tank to the engine is cooled down and lubricated by the fuel itself. Presence of foreign elements will hinder this operation. If water remains in the pump body for long, rust formation will also commence. Since water is denser than fuel, it remains at the bottom of the tank. The fuelling system is constructed such that fuel is sucked from the bottom of the tank. This will cause a higher proportion of water to get into the fuel system and ultimately into the engine. As explained earlier, the injectors and fuel lines might be affected by this.
4. Lubrication Problems:
If the engine has a faulty gasket, water (after being pumped into the engine) might leak into the oil sump. If the amount of water is high, it will form a sluggish mixture with the engine oil. This will seriously affect the lubricating property of the engine.
5. Engine Seize:
A combination of all the above problems will lead to a complete engine failure. The intensity of the problem might range from a simple fuel line flushing to even the replacement of the entire engine.
