What are the symptoms of a car running on water-contaminated gasoline?
1 Answers
Using gasoline mixed with water can significantly impact a car's engine. The symptoms of a car running on water-contaminated gasoline are as follows: 1. At the moment of startup, when a piston moves upward to complete the compression work before ignition, the intake valve closes almost simultaneously, creating a sealed space inside the cylinder. Since water is incompressible, the piston will encounter significantly increased resistance as it moves upward to a certain position. However, the crankshaft driven by other working pistons is determined to push this piston to the top dead center. The accumulated water will be expelled from the cylinder when the exhaust valve opens during startup, but the damage to the connecting rod is already done. A bent connecting rod inadvertently reduces the cylinder's compression ratio and increases the engine's operational resistance, making the vehicle feel less powerful than before. 2. A slightly bent connecting rod makes the piston's movement in the cylinder extremely unstable, and higher RPMs undoubtedly accelerate its deterioration. Additionally, the piston's erratic movement in the cylinder worsens the bending of the connecting rod. The more the connecting rod bends, the more violently the piston will wobble during operation, eventually leading to damaged piston rings, cylinder walls, and the piston seizing in the cylinder. The connecting rod may also bend or break under immense pressure, and in more severe cases, a broken connecting rod can puncture the engine block directly. The engine then loses power, and the vehicle will come to a stop after a short coast.
