Does Driving Through Deep Water Affect the Car?
1 Answers
Driving through deep water does affect the car, and the potential hazards of driving through water are as follows: 1. Crankshaft bending: Rainwater may enter the engine cylinders through the intake and exhaust systems. Due to the incompressibility of water, it can cause bending deformation of the valve linkage and piston crankshaft, and in severe cases, damage the cylinder block. 2. Electrical circuits in the car: Especially if the engine control unit (ECU) gets wet, it can cause a short circuit. If the ECU is damaged by water, the only option is to replace it. 3. Water ingress: Since water pressure is much lower than the exhaust pressure of the cylinder, as long as the engine does not stall, water generally will not flow back into the exhaust pipe. In 90% of cases, water entering the engine cylinders is caused by water entering through the intake. Below are measures to take after water ingress: 1. When the car enters the water, try to keep the vehicle as balanced as possible: Avoid rushing in and splashing water onto electrical components or allowing water to enter the engine's intake system. The correct driving method is to reduce speed first, shift to a lower gear, preferably using first gear to keep the engine speed at around 4000 rpm, maintaining a steady and even speed. 2. Do not stomp on the accelerator: This would cause a sudden increase in engine load, which could draw water droplets into the engine due to the sudden surge in air intake. If you notice the wheels slipping or sinking, remember not to accelerate abruptly. Instead, with the engine still running, try to drive out of the water with the help of manpower or another vehicle.
