What is the temp setting for cold air in a car?

In a car, a temp setting of 18°C produces cold air. Below is relevant information about car temp: Definition: Temp in a car refers to temperature, which can be adjusted via buttons. The temp button is generally located on the car's center console, and some models also have it at the rear air vents for independent control of rear air conditioning temperature. Adjustment method: There's a temperature adjustment knob on the car's dashboard with red and blue ends. Turning it fully to the red side produces hot air, while turning it fully to the blue side produces room-temperature air. To get cold air, you need to additionally press the compressor AC switch to activate the cooling system.

How to Remove Whitening Caused by Waxing on Car Plastic Parts?

To remove whitening caused by waxing on car plastic parts, you can use toothpaste to wipe the surface. After cleaning, apply a bright white spray paint to restore the shine. The benefits of car waxing include: 1. Waterproofing: Car wax can reduce water droplet adhesion on the car's surface by 60% to 90%; 2. Heat resistance: It prevents incident light from penetrating the clear coat, which can cause the base paint to age and discolor, thereby extending the paint's lifespan; 3. Anti-static: Waxing creates a barrier between the air, dust, and the car's paint surface, preventing static electricity and significantly reducing dust adhesion; 4. UV protection; 5. Gloss enhancement; 6. Polishing: When there are shallow scratches on the paint surface, waxing with polishing can be used. If the scratches are not deep, polishing and waxing can be completed in one step.

What are the reasons for insufficient power in motorcycles?

There are many reasons that can cause insufficient power in scooters. Apart from the inherently small engine displacement and limited power performance, the main reasons for insufficient power in scooters are as follows: Engine malfunction: Insufficient power leading to weak vehicle performance, inability to increase engine RPM. It is necessary to check the engine's operating condition, whether there is insufficient fuel intake, whether the air filter is clogged, whether the exhaust is obstructed, and whether the high-voltage electricity is normal. Component wear: The engine has RPM and strong power, but the vehicle's power performance is low. It is necessary to check whether the brake pads return to position normally, whether the components inside the transmission (box) are worn or aged, etc. A mechanic should be consulted to test drive and confirm the issue.

Does gasoline expand with heat and contract with cold?

Yes, but the thermal expansion and contraction of gasoline is not significant. Here are the relevant details: Related knowledge: For gasoline, its density is much lower than that of water, so one liter of gasoline certainly does not weigh one kilogram. At room temperature of 25°C, taking 93-octane gasoline as an example, its weight is approximately 0.725 kilograms. Therefore, one liter of gasoline still weighs around 0.7 kilograms, which is far from one kilogram. When the temperature rises, its volume increases, and consequently, its density decreases. From this perspective, the thermal expansion and contraction of gasoline can to some extent affect its density, although this change is very minimal. Thermal expansion and contraction of gasoline: Gasoline does expand with heat and contract with cold. For every 1°C increase in temperature, the volume of gasoline expands by approximately 0.12%.

What issues should be paid attention to when overtaking?

Overtaking requires attention to the following issues: 1. Comprehensive observation of traffic conditions: Before overtaking, not only observe the traffic conditions ahead and to the left, but also check the traffic behind through the interior and exterior rearview mirrors. When overtaking, turn your head to observe the dynamics of the vehicle being overtaken. 2. Reasonable selection of overtaking timing: Overtake when oncoming traffic does not affect the maneuver. Before overtaking, ensure that the oncoming vehicle is far beyond the overtaking distance, so that passing the vehicle ahead will not be hindered by oncoming traffic. 3. Accelerate and merge into the adjacent lane: Accelerate straight to pass the vehicle to be overtaken at a safe distance, then merge back into the original lane.

Will the fare keep increasing if the taxi is stuck in traffic?

Yes, the fare will increase. Because the cost of Didi Chuxing is calculated in two parts: one is the distance, and the other is the time, and the time-based charge is more expensive than that of regular taxis, so the cost will be higher when stuck in traffic. More about taxi services: Relevant regulations: On July 28, 2016, the General Office of the State Council issued the "Guiding Opinions on Deepening Reform and Promoting the Healthy Development of the Taxi Industry," and the "Interim Measures for the Administration of Online Booking Taxi Operation Services" was also jointly released by seven departments including the Ministry of Transport. The new regulations granted online ride-hailing services legal status and clarified that private cars meeting certain conditions can be converted into online ride-hailing vehicles. Additional information: Didi Chuxing is a ride-hailing platform in China. It is known as the mobile "taxi-hailing magic tool" and is a popular ride-hailing application platform among users. Currently, Didi has evolved from a taxi-hailing software to a one-stop travel platform covering multiple services, including taxis, premium cars, express cars, carpooling, designated drivers, and buses.
