Is the Highway Not Free During Mid-Autumn Festival?

The toll issue of the Mid-Autumn Festival highway is specifically introduced as follows: 1. Toll on the Mid-Autumn Festival highway: The highway is not free during the Mid-Autumn Festival. 2. Conditions for highway toll exemption: Currently, highway toll exemption only applies to important holidays, and there are certain requirements for vehicles, which means only small cars with seven seats or less, i.e., policies for private cars. Commercial vehicles, of course, still have to pay tolls. Vehicles that meet the regulations are exempt from tolls nationwide during these holidays. 3. The holiday period starts at 00:00 on the day and ends at 24:00 on the last day, which is common knowledge. So, what if you enter the highway before the holiday and exit during the holiday? In this case, it is free, meaning the standard for highway toll exemption is that as long as you exit the highway during this period, it is free, regardless of when you enter the highway.

How many liters does it take to fill up the Sylphy's fuel tank?

The fuel tank capacity of the Sylphy 1.2L model is 41 liters, the classic 1.6L model has a 50-liter tank, and the 1.6L-CVT version comes with a 47-liter tank. These figures are officially released data. The Sylphy uses 92-octane fuel. The 1.2L model has a fuel consumption of 3.9L per 100 kilometers, allowing a range of 1051km on a full tank. The classic 1.6L model consumes 5.2-6.1L per 100 kilometers, providing a range of 819-961km on a full tank. The 1.6L-CVT version consumes 4.9-5.3L per 100 kilometers, offering a range of 886-959km on a full tank. During daily driving, it's essential to monitor the remaining fuel level in the tank. This is typically done by observing the fuel gauge inside the vehicle. If there are no other issues, the fuel level will be accurately reflected on the gauge. The fuel gauge usually has 5 to 6 segments, and it's advisable to refuel when there are about 2 segments left to avoid running out of fuel midway. In actual refueling, the amount of fuel might exceed the marked capacity. This is because the fuel tank capacity specified by the manufacturer is measured from the bottom of the tank to the safe limit. There is additional space from the safe limit to the tank opening, which is designed to allow for fuel expansion due to temperature increases without causing overflow. If fuel is filled up to the tank opening during refueling, the actual amount of fuel added may exceed the marked tank capacity.

How to Prevent Car Fires?

Methods to prevent car fires: 1. Fires usually have early warning signs, such as unusual noises or odors from the vehicle. In such cases, you should immediately turn off the engine and park the car in a sheltered area; 2. Locate the source of the fire, but avoid hastily opening the hood, as introducing air can fuel the fire. Have a fire extinguisher ready before opening the hood; 3. If the fire becomes uncontrollable, call emergency services immediately and also contact your insurance company to report the incident, obtaining a claim number or requesting an on-site assessment; 4. After the fire is extinguished by the fire department, request a fire report and an explanation of the fire cause; 5.

What causes the car to shake when accelerating from 60 to 80 mph?

The reasons for the car shaking when accelerating from 60 to 80 mph are as follows: Loose drive shaft: Check if the drive shaft (i.e., the half shaft) is loose. You can also perform a test drive to inspect. The inspection method is to release the throttle and shift to neutral at 80 mph. If it doesn't shake, it's a half shaft issue. If it still shakes, perform a four-wheel dynamic balance check to see if there is water inside the tires. Excessive gap in suspension ball joints or connecting components: When the car accelerates from 60 to 80 mph, the front body shakes, but it doesn't shake when not pressing the throttle or at other speeds. This is caused by excessive gaps in the front suspension ball joints or connecting components, which create shaking at a certain frequency. It is necessary to go to a repair shop to adjust the toe-in and front wheel alignment.

Does Using Air Conditioning While Parked Damage the Car?

Using air conditioning while parked can indeed harm the vehicle. Keeping the car idling with the AC on for extended periods leads to several issues: it increases fuel consumption, accelerates engine carbon buildup, and in poorly ventilated areas or garages, may cause carbon monoxide poisoning for occupants. Below are the specific hazards of leaving the air conditioning on while the car is parked: 1. Carbon Monoxide Production: When the engine runs, incomplete combustion in the cylinders can produce high concentrations of carbon monoxide. While driving, air flow through the AC system ensures low CO levels inside. However, when parked with AC on and windows closed, stagnant air allows CO from the exhaust to accumulate, potentially leading to poisoning or fatalities. 2. Battery Drainage: Although the AC compressor is engine-powered, the blower fan relies on the battery. During idling, the alternator may not sufficiently recharge the battery, causing prolonged power depletion from continuous blower operation. 3. Engine Carbon Deposits: Extended AC use while idling increases fuel consumption and significantly contributes to carbon buildup within the engine components.
