Is It Dangerous to Leave Windshield Washer Fluid in the Trunk Under the Sun?

What is the reason for the difference in fuel consumption between national highways and expressways?

The reason for the difference in fuel consumption between national highways and expressways is that the speed at which a car travels on a national highway differs from that on an expressway, leading to variations in fuel consumption rates. Overview of vehicle speed: Vehicle speed refers to the distance a car travels per unit of time, commonly referred to as speed, with units typically expressed in kilometers per hour or meters per second. Vehicle speed is one of the three parameters used to describe traffic flow and holds significant importance in traffic flow theory research. Classification of vehicle speed: Vehicle speed can also broadly refer to motor vehicle speed. To accommodate different purposes, vehicle speed is mainly categorized into spot speed, segment speed, and design speed. Spot speed is the instantaneous speed of a vehicle passing a specific point on the road. Design speed is the speed established to determine the design indicators of various geometric elements of the road and to ensure their coordination.

What are Road Warning Markings?

Warning markings are designed to alert motor vehicle drivers and pedestrians to changes in road conditions, enhancing vigilance, accurate prevention, and timely response measures. These include lane width transition markings, obstacle approach markings, and railway crossing approach markings. Lane width transition markings warn drivers of narrowing road widths or reduced lane numbers, advising cautious driving and prohibiting overtaking. Obstacle approach markings indicate the presence of fixed obstacles on the road surface. Railway crossing approach markings signal an upcoming railway crossing, warning drivers to proceed with caution. Violations related to these markings include: both single and double solid yellow lines are prohibitive markings, and crossing or driving over them is illegal; failing to follow directional markings in the appropriate lane at intersections is also a violation; illegal temporary or long-term parking; making U-turns in no-U-turn zones or left turns where prohibited are all considered violations of prohibitive markings.

Why Turn on the Left Turn Signal in the Fast Lane on the Highway?

Reasons for turning on the left turn signal in the fast lane on the highway are as follows: Signaling to the rear vehicle: When driving in the fast lane, if you notice from the rearview mirror that a vehicle in the right lane wants to change lanes into the fast lane but is hesitant due to fear of sudden right lane changes, you can turn on the left turn signal to indicate that you have no intention of changing lanes to the right. This allows the other vehicle to change lanes with confidence. Alerting the front vehicle: To remind the vehicle ahead, nowadays, there are quite a few drivers who occupy the fast lane for extended periods or even drive at very low speeds in the fast lane. This poses significant risks to normal traffic flow. Therefore, turning on the left turn signal at this time serves as an effective reminder for the other vehicle to move away quickly.

How long does it take to drive a dozen kilometers?

Driving time depends on the speed. Generally, the speed in urban areas is 30 to 50 km/h, taking about 10 minutes. The driving time is also related to road conditions, traffic lights, speed limits, and other factors. Time required for urban roads: If the speed limit on urban roads is 60 km/h, it takes 15 minutes to cover 15 kilometers without considering traffic lights. Including the waiting time for traffic lights, it would take around 16 minutes. If driving at the regulated speed, for example, a speed limit of 40 km/h, it would take 22.5 minutes to cover 15 kilometers without traffic lights, and around 23 minutes including traffic light waiting time. Time required for special road conditions: For special road conditions such as flooded roads, slopes, or muddy roads with a speed limit of 30 km/h, it would take 30 minutes without considering traffic lights.

How many kilometers should the spark plugs of the Envision be replaced?

Envision spark plug replacement cycle: Under normal maintenance conditions, replace after driving 40,000 to 60,000 kilometers. However, due to differences in brands and engines, it may vary. It is recommended to follow the user manual. You can refer to the following standards for maintenance replacement: Platinum spark plugs should be replaced at 40,000 kilometers, ordinary nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000 to 80,000 kilometers. How spark plugs work: The spark plug's ground electrode is connected to the metal shell, which is threaded into the engine block via the cylinder head. The insulator mainly serves to isolate the metal shell and the central electrode. The terminal nut is the part of the spark plug that contacts the high-voltage coil. When current passes through the terminal nut and the central electrode, it ionizes the medium between the central electrode and the ground electrode to produce a spark, thereby igniting the air-fuel mixture in the cylinder.

How Much Refrigerant Should Be Added to a Car Air Conditioner?

Generally, a car air conditioner requires 4 cans of refrigerant, but the actual amount is controlled based on the pressure gauge readings during operation. Below are the methods and timing for adding refrigerant to the air conditioner: Method for Adding Refrigerant to a Car Air Conditioner: Prepare qualified refrigerant charging tools, connect the car air conditioner to the charging tool adapter, evacuate the system, and inject liquid refrigerant from the high-pressure side to complete the refrigerant charging. During the process, constantly monitor the high and low pressures. Typically, the low pressure should be 150-250 Kpa, and the high pressure should be 1300-1500 Kpa. Specific values can be referenced in the user manual. Timing for Adding Refrigerant to a Car Air Conditioner: Normally, refrigerant should be added every 2-3 years. However, if the owner notices a decline in cooling performance or continuous bubbles in the sight glass of the air conditioner's tubing, refrigerant should be replenished.
