What are the effects of water in gasoline on the engine?
2 Answers
If there is water in the gasoline, it will affect the normal combustion of the gasoline in the cylinder, leading to symptoms such as abnormal engine shaking, poor acceleration, and difficulty starting. Below is some relevant information about automotive gasoline: 1. Overview: Automotive gasoline is a liquid fuel refined from petroleum, mainly used for cars and motorcycles. 2. Classification: In China, automotive gasoline is divided into unleaded and leaded types. The unleaded types have octane ratings of 90, 93, and 95 RON (Research Octane Number). The leaded types have octane ratings of 90, 93, and 97 RON. Among them, the lead content in 90 RON does not exceed 0.35g/L, while the lead content in 93 and 97 RON does not exceed 0.45g/L.
I once encountered a situation where water got into the gasoline while driving. It happened after refueling at a suburban gas station. The car started shaking violently while driving and almost broke down. It turned out that water had mixed into the gasoline. When water is sucked into the engine, it cannot burn, leading to incomplete combustion. The engine made crackling sounds, and the horsepower dropped sharply. Over time, it can also corrode fuel injectors and pistons, increasing repair difficulty. That time, I spent over 3,000 yuan replacing parts and also delayed my trip. Since then, I've only gone to major brand gas stations to avoid fuel with water content, and my car hasn't had similar problems again.
