How Does Oil Film Form on Car Windows?

The causes of oil film formation on car windows are as follows: 1. Vehicle exhaust: Primarily from vehicle exhaust, which contains various pollutants due to incomplete combustion. Frequent traffic congestion in urban areas, especially when driving behind trucks, inevitably leads to these pollutants adhering to the car windows, forming an oil film. 2. Cooking fumes: Next is pollution from cooking fumes. If the car is often parked near restaurant chimneys, over time, a significant amount of grease and dirt accumulates. If not cleaned promptly, it can form a thick layer of oil residue. 3. Insect remains, bird droppings, and tree resin: Insect remains and bird droppings are highly corrosive. If left uncleaned on the glass, they harden and adhere, affecting the glass's transparency and even turning into an oil film. Additionally, tree resin is another factor. Cars frequently parked under trees may be coated with tree sap or fruit residues, leading to oil film formation.

Do You Need to Fully Depress the Brake When Shifting an Automatic Transmission?

When driving an automatic transmission vehicle, you don't need to press the brake to shift gears, as all shifting actions are autonomously completed by the transmission without manual intervention. Generally, when driving an automatic transmission car, if you accelerate to a certain speed, such as 2500 RPM, and then slightly release the throttle, the transmission will upshift on its own. If you keep pressing the throttle without releasing, some automatic transmission vehicles will delay the shift until higher RPMs. Below are situations where you need to press the brake: 1. Starting in P (Park) gear: When starting the car in P gear, you must press the brake. Since the car is just starting, not pressing the brake can easily cause the vehicle to roll. 2. Driving in N (Neutral) gear: When driving in neutral, you should press the brake. In fact, experienced drivers do not recommend driving in neutral. But if you must shift to neutral, remember to press the brake to avoid emergencies that cannot be resolved. 3. Shifting from N (Neutral) gear: When shifting from N gear to D (Drive) or R (Reverse) gear, you also need to press the brake. Not pressing the brake can cause the car to lurch forward or stop abruptly, which can cause significant damage to the transmission system.

What to Do About Throwing Objects Out of Car Windows?

Throwing objects out of car windows is an illegal act, and traffic police departments will impose fines for such behavior. According to Article 62 of the national "Regulations for the Implementation of the Road Traffic Safety Law," it is explicitly stipulated that while driving a motor vehicle, the driver must not throw objects onto the road, and other passengers in the vehicle are similarly prohibited from throwing items outside the car. Some cities in our country's "Road Traffic Safety Law" regulations state that if a driver is found throwing trash or debris out of the car window, the driver will be penalized with 2 demerit points and a fine. Passengers who throw garbage out of the car will also be fined. If littering causes other traffic accidents, the individuals in the vehicle will bear the corresponding accident responsibility.

What Are the Causes of a Faulty Thermostat?

Due to prolonged warm-up time, electric flatbed trucks operate at lower water temperatures, causing combustion gases to form acidic substances with the water condensed on the cylinder walls, which corrode the cylinders and lead to thermostat failure. Below is some relevant information about thermostats: 1. Introduction: A thermostat automatically adjusts the amount of water entering the radiator based on the coolant temperature, altering the water circulation range to regulate the cooling system's heat dissipation capacity, ensuring the engine operates within an appropriate temperature range. 2. Working Principle: The most commonly used thermostat is the wax-type thermostat. When the coolant temperature is below the specified value, the refined paraffin inside the thermostat's temperature-sensing body remains in a solid state, and the thermostat valve closes the channel between the engine and the radiator under the action of a spring. The coolant then returns to the engine via the water pump, initiating a small internal circulation within the engine.

What Temperature Rating for Windshield Washer Fluid in Winter

In winter, you should choose windshield washer fluid with a freezing point at least 10°C lower than the local minimum temperature. Here is relevant information about windshield washer fluid: 1. Cleaning performance: Windshield washer fluid is compounded from various surfactants and additives. Surfactants usually have functions such as wetting, penetrating, and solubilizing, thereby achieving the effect of cleaning and removing dirt. 2. Antifreeze performance: It can significantly reduce the freezing point of the liquid, thus playing an antifreeze role and quickly dissolving frost. 3. Anti-fog performance: A single-molecule protective layer forms on the glass surface. This protective film can prevent the formation of fog droplets, ensuring the windshield remains clear and transparent with a clear field of vision.
