What is the biggest problem with flood-damaged cars?
1 Answers
The problems with flood-damaged cars are as follows: 1. Electronic system failure: Modern vehicles are equipped with various functions, and it's not an exaggeration to say they are collections of electronic components. Non-professional off-road vehicles generally have little waterproof treatment for their electronic equipment. After water exposure, the engine's related electronic modules are prone to short circuits due to rust and corrosion caused by water immersion. Additionally, car wiring is usually routed along the bottom edges of doors, making it easily soaked. If these modules and circuits malfunction, the consequences can range from a single function failure to vehicle destruction, or even fires caused by short circuits. 2. Engine failure: When the water level is higher than the engine's air intake, water naturally flows into the cylinders, forming a mixture of air and water. While air is compressible, water is not. When the crankshaft pushes the connecting rod to compress the piston, the incompressible water causes the connecting rod to deform and bend. If the owner attempts to restart the vehicle after the engine stalls due to water intake, the tremendous reverse force can cause the bent connecting rod to rub against the cylinder wall, instantly rupturing the engine block.
