Car spare tires have a lifespan of four years. Below is a detailed introduction about car spare tires: 1. Spare tires are rubber products and will age over time: The aging cycle of a spare tire is 4 years, so it needs to be replaced every four years. 2. Spare tires are not suitable for long-term use: Spare tires are smaller and used less frequently, with different aspect ratios and widths compared to regular tires. After replacing with a spare tire, the friction coefficients of the four tires differ, and so does the ground adhesion. Prolonged use can affect the vehicle's braking system. 3. Spare tires should not be used for high-speed driving: Spare tires cannot match regular tires and require more protection. After installing a spare tire, the driving speed should not exceed 80 km/h to avoid accidents.

What is the fuel tank capacity of the 2014 Volkswagen Polo in liters?

2014 Volkswagen Polo has a fuel tank capacity of 45 liters, which is the officially announced data. Owners who have purchased the 2014 Volkswagen Polo can also check this information on the vehicle's configuration sheet. The 2014 Volkswagen Polo requires 92-octane gasoline, with a fuel consumption of 7.0 to 7.5L per 100 kilometers. A full tank can cover a distance of 600 to 643km. During daily driving, it is necessary to pay attention to the remaining fuel level in the tank at all times. Generally, the fuel level is observed through the fuel gauge inside the car. If there are no other issues, the fuel level will be accurately reflected on the gauge. The fuel gauge typically has 5 to 6 segments, and it is advisable to refuel when there are only 2 segments left to avoid running out of fuel midway. During actual refueling, the amount of fuel may exceed the marked capacity. This is because the fuel tank capacity marked by the car manufacturer is the volume from the bottom of the tank to the safe limit. There is additional space from the safe limit to the tank opening, which is reserved to allow for fuel expansion when temperatures rise, preventing overflow. If fuel is filled up to the tank opening during refueling, the actual amount of fuel added may exceed the marked tank capacity.

Reasons for the Poor Performance of the GAC Trumpchi GS4's Heating System

GAC Trumpchi GS4's heating system does not work well because it needs to wait for the car's water tank temperature to rise to a certain level before the engine's preheating can be delivered to the cabin. Non-independent Heating System: The GAC Trumpchi GS4 uses a non-independent heating system. The non-independent heating system, also known as a residual heat heating system, utilizes the residual heat from the car's exhaust or the engine's cooling cycle water as a heat source and introduces it into a heat exchanger. A fan then blows air from inside or outside the car through the heat exchanger to warm it up. This is why some people say that using the heater in winter does not consume extra fuel. Automotive Air Conditioning Heating System: The main function of the automotive air conditioning heating system is to work together with the evaporator to adjust the air to a comfortable temperature for the occupants, providing warmth to the car's interior in winter and improving the internal environment temperature. When the car's windows are frosted or fogged, it can deliver hot air to defrost and defog. There are several forms of heating equipment, which can be divided into non-independent (engine-based) heating systems and independent (non-engine-based) heating systems based on the heat source used.
