Liquid water is discharged from the exhaust pipe as the engine operates at high speed, causing water to drip from the car chassis. Here are the details: Introduction: When gasoline is injected into the cylinder and mixed with air, it burns completely in the combustion chamber, primarily producing carbon dioxide and water. The water is discharged into the atmosphere as water vapor in a gaseous state under high temperatures. Since the muffler is located at the rear of the car where the temperature is relatively low, the water vapor condenses into liquid water upon cooling. Some of this liquid water is expelled from the exhaust pipe due to the airflow generated by the high-speed operation of the engine, resulting in water dripping or even spraying from the exhaust pipe. Abnormal phenomena related to the car chassis include: Oil leakage from lubricants—if oil or gear oil leaks when the car is started after being parked for several hours, it indicates a problem. Coolant leakage—coolant not only prevents freezing but also has anti-corrosion, anti-rust, and heat-conducting properties. If liquid is found leaking from the upper or lower hoses of the radiator or if there is leakage from the radiator itself, immediate repair is necessary.

What are the precautions for safe driving?

Precautions for safe driving: 1. The stronger the high beam at night, the less safe the driving is. The larger the angle of light irradiation, the safer it is. The higher and brighter the light is raised, the more dangerous it is; 2. After parking on uneven ground, not only should you pull the handbrake, but also engage the gear. This is the appropriate method to prevent the vehicle from sliding due to uneven road surface; 3. It is unsafe to depress the clutch while braking during high-speed turns. In any case, driving with the clutch depressed will increase the vehicle's inertia. You should lower the gear and then brake while driving; 4. On slippery roads, learn to use the gear properly to control the vehicle's movement; 5. When accelerating to overtake, observe and judge the situation behind. After confirming that no vehicle behind intends to overtake you, observe and judge the situation ahead.

What does 4S store replacement subsidy mean?

Automobile replacement subsidy is aimed at used cars over 5 years old, intended to be provided in the form of cash subsidies, with the cost shared equally by Beijing Municipality and automobile companies. The following is an introduction to the replacement subsidy: Understand the price of used cars: Before replacement, it is advisable to refer to some appraisal prices. You should neither underestimate the price of your vehicle nor overestimate it. It is best to drive the car directly to a used car brokerage company with certain brand recognition and strength for an actual appraisal. Grasp the preferential situation of new cars: You should not only understand the price of used cars but also the price of the new car you intend to replace and the recent promotional offers. Trade old for new: After understanding the actual purchase price of your vehicle, you can refer to the used car purchase price to consider the ideal discount for the new car. Generally speaking, new car dealers without used car business projects are not very confident in pricing used cars when replacing them, and the purchase price of used cars will be slightly lower than that of brokerage companies. But don’t worry, be sure to check the discount on the new car again. If the discount on the new car does not meet your expectations, you can also negotiate with the dealer on the used car. Generally speaking, in replacement, there is little room for negotiation on the discount of new cars, but there is some room for adjustment on the price of used cars. Car owners can make some adjustments here, but these adjustments will not deviate far from the overall market transaction conditions.
