How to Deal with Water Droplets on Rearview Mirrors on Rainy Days?

There are several measures to remove small water droplets from rearview mirrors on rainy days. Here are the specific methods: Using Rearview Mirror Heating to Remove Water Droplets: Utilize the car's rearview mirror heating function. However, this method has certain limitations: the heating process is slow, and the switch only affects the rearview mirrors, leaving the side windows unheated. In heavy rain, its effectiveness is minimal. Installing Rain Guards to Reduce Water Droplets: Rain guards, also known as "rearview mirror rain visors," are made of resin material and can be bent flexibly. They are attached to the rearview mirrors using specialized double-sided tape, functioning like a small umbrella over the mirrors. Installed rain guards are quite effective in light rain. However, in heavy rain, their effectiveness diminishes, especially against diagonally falling rain. Using Soap or Dishwashing Liquid to Reduce Water Droplets: This requires advance waterproofing preparation. Before driving, apply bar soap or dishwashing liquid to the rearview mirrors and side windows. Once the surface dries, wipe the glass clean with a cloth or tissue. Practical tests show that glass treated with these substances remains free of water droplets even in heavy rain. Additionally, shampoos and body washes also have water-repellent properties and can be used similarly. The reason is that these products contain surfactants. When applied to the rearview mirrors, even after rinsing off the foam, the surfactants remain on the surface, creating a protective film.

What Causes a Car to Feel Sluggish?

Reasons for a car feeling sluggish: engine fuel system malfunction, intake system malfunction, engine misfire. Engine fuel system malfunction: If the car's fuel injectors are clogged, fuel lines are leaking, the fuel filter is blocked, or the fuel pump's power is reduced, the car will exhibit symptoms of poor acceleration. The underlying reason is that the engine does not receive sufficient fuel during acceleration, leading to decreased combustion efficiency. Solution: Check the fuel level in the float chamber. If it meets the requirements, then inspect whether the main jet is properly adjusted and if there is any blockage. If a fault is found, proceed with repairs. Intake system malfunction: Combustion cannot occur without air. If the engine's air intake is insufficient, the combustion efficiency will naturally decrease. If the car's air filter is clogged, the throttle body has severe carbon buildup, or there is a leak in the intake pipe, these issues can all cause poor acceleration. Solution: Open the intake manifold switch valve cover, place a listening rod against the intake manifold switch valve, start the engine, and repeatedly press the accelerator pedal. This can help diagnose whether there is a fault in the intake system, followed by targeted repairs. Engine misfire: In this case, the engine and steering wheel will exhibit noticeable vibrations. Generally, a four-cylinder engine can still operate with one cylinder misfiring, but if the number of misfiring cylinders increases, the engine will stop working. This can also lead to poor acceleration or a sluggish feeling in the car. Solution: Take the car to a professional repair shop for servicing.

Why Does the Car Vent Blow Hot Air?

Reasons for the car vent blowing hot air: the external circulation is on, allowing hot air from the engine compartment to enter the cabin; or the external circulation is on and the temperature setting is for hot air. External circulation is on, allowing hot air from the engine compartment to enter the cabin: The car's air conditioning system has both internal and external circulation modes. Internal circulation draws air from inside the car, while external circulation draws air from outside. When driving, airflow enters the engine compartment through the front grille, creating positive pressure, which can force hot air from the engine compartment into the cabin through the external circulation intake. This results in hot air blowing from the vents. Solution: Turn off the external circulation. Note that in automatic air conditioning systems, the external circulation cannot be turned off in windshield defrost mode. If hot air is blowing but you can't turn off the external circulation, switch the vent position to any setting other than windshield defrost to disable the external circulation. External circulation is on and the temperature setting is for hot air: The car vents can blow either hot or cold air. The principle is simple: there is an air duct under the dashboard containing a heater core and an evaporator. The heater core is connected to the engine's cooling system and contains high-temperature coolant. The evaporator is part of the air conditioning system, where refrigerant evaporates to absorb heat and produce cold air. A baffle in the duct controls airflow—when cold air is selected, the baffle blocks the heater core, preventing airflow from being heated. When warm air is selected, the baffle opens, allowing airflow to pass over the heater core and be heated before entering the cabin. Solution: Turn off the external circulation or adjust the temperature knob to a cooler setting. Turning off the external circulation stops airflow, preventing hot air from blowing. Adjusting the temperature knob to a cooler setting ensures the baffle blocks the heater core, preventing it from heating the air.

How Does an Automotive Relay Work?

Automotive relays operate by generating a magnetic field when the coil is energized, which then attracts the connected contact plate to complete the circuit, thereby protecting the circuit. Typically, the two wires of the coil are connected to positive and negative terminals, with one end connected to a switch. The other wires are connected to the electrical device. Automotive relays are widely used to control various functions in vehicles, including starting, preheating, air conditioning, lighting, wipers, fuel injection, fuel pumps, anti-theft systems, audio systems, navigation, electric fans, cooling fans, power windows, airbags, anti-lock braking systems (ABS), suspension control, as well as automotive electronic instruments and diagnostic systems. Their usage is second only to sensors in terms of quantity. The function of a relay is to enable one signal or pulse to open or interrupt another current. Typically, relays use lower voltage or current to control higher voltage or current. These low-voltage/current signals can be activated by smaller, more affordable switches and transmitted via smaller-gauge wires to the relay. Thus, relays can be used to control larger currents. For example, in an automotive engine, turning on the ignition switch sends a signal to the relay near the starter.

Does Car Air Conditioning Consume Fuel or Electricity?

Car air conditioning consumes fuel rather than electricity. If it's an electric vehicle, then it uses electricity. Currently, most cars charge the onboard battery via the gasoline engine, and a standard lead-acid battery cannot power the air conditioning system. Although the air conditioning uses electricity, this electricity is provided by the car engine, which ultimately consumes gasoline. The air conditioning compressor is the most critical component of the air conditioning system and also the most energy-consuming part. In traditional fuel-powered vehicles, the compressor is typically connected directly to the engine and driven by it, rather than being electrically powered. This is why using the air conditioning consumes fuel instead of electricity. Fuel consumption of car air conditioning: Different compressors consume varying amounts of fuel. Generally, the power consumption of car air conditioning accounts for about 20% of the engine's power. Using the air conditioning diverts a portion of the engine's power, leading to increased fuel consumption. The exact increase in fuel consumption depends largely on the car's displacement and speed. For example, a car that normally consumes 10 liters of fuel per 100 kilometers may see an increase of about 2 liters when the air conditioning is on. Therefore, for variable compressors, the impact of air conditioning on fuel consumption is quite significant, while the effect of different fan speeds is relatively smaller. This is just a rough estimate; the actual fuel consumption depends on the specific car model, speed, and road conditions.
