How many kilometers can a spare tire last approximately?

Replacing with a full-size spare tire can run over 100 kilometers without any issues, while a non-full-size one should not exceed 60 kilometers. Here is some information about tire usage: 1. When checking whether a tire meets the replacement standard, you can judge by the wear indicators on the tire. When the wear indicators in the tire grooves are level with the tire tread, it indicates that the tire's grip and drainage performance are very poor. In such cases, it is recommended to replace the tire. 2. Under long-term exposure to sunlight, ultraviolet rays and high temperatures can cause the rubber on the tire to harden and crack. After these problems occur, the elasticity of the rubber and its tensile resistance will sharply decrease. 3. The phenomenon of surface cracking and aging on tires generally occurs after more than 5 years, meaning that tires used for 5 years or more will have significantly reduced safety coefficients and comfort levels. At this point, the tires need to be replaced.

What to Do When a Car is Not Used for a Long Time?

Methods for dealing with a car that has been idle for a long time: 1. If possible, prioritize parking in an underground parking space. This effectively protects the car's paint. The outermost layer of the car's paint is clear coat, composed mainly of epoxy resin, which protects the color coat. Under prolonged exposure to sunlight, bird droppings, tree leaves, fruit sap, etc., the paint can easily lose its luster. Additionally, attachments like leaves and fruit sap can form small yellow spots that are hard to clean. Therefore, try to park underground for long periods. If conditions don't allow, remember to cover your car with a car cover. 2. Disconnect the car's power supply. The most common issue when a car is not used for a long time is battery drain, making it difficult to start the car next time. 3. Adjust the tire pressure. If a car is left unused for a long time, the tires bear weight on the same spot, leading to irreversible deformation over time. Thus, increasing the tire pressure is necessary. 4. Don't fill the fuel tank too much, as fuel can deteriorate. Avoid filling the fuel tank to the brim. Under normal conditions, gasoline has a shelf life of about three months, while ethanol-blended gasoline typically lasts only a month. Avoid using ethanol-blended gasoline for long-term parking. It's recommended to keep the fuel level at about a quarter of the tank. 5. Remove flammable items from the car when parking for a long time. Items like perfumes and lighters can pose a risk. In high summer temperatures, especially if the car is parked outdoors, the interior can get extremely hot, potentially causing flammable items like lighters and perfumes to explode or catch fire. Therefore, it's essential to remove such hazards promptly.

What causes the ignition device of BMW 5 Series to fail to start?

BMW 5 Series ignition device fails to start for the following reasons: Excessively rich air-fuel mixture: If the engine has difficulty starting when hot but starts normally when the accelerator pedal is fully depressed (no fuel injection when fully depressed), it indicates an excessively rich air-fuel mixture. In this case, the air filter element can be removed to release some of the accumulated rich mixture in the intake tract. Additionally, removing the filter element reduces intake resistance; the lower the intake resistance, the leaner the air-fuel mixture becomes, allowing normal starting. Focus should be on checking whether the charcoal canister solenoid valve is stuck in the open position. Excessive carbon deposits in the throttle system and bypass air passage: If the accelerator pedal feels much heavier than usual when pressed for the first time each day, and the engine has difficulty starting, but starts normally when the pedal is slightly depressed, it indicates excessive carbon deposits in the throttle. These deposits block the throttle, causing starting difficulties. Slightly depressing the accelerator pedal during startup ensures sufficient air intake, allowing normal starting, but releasing the pedal while driving will cause the engine to stall immediately. The throttle system and bypass air passage should be cleaned promptly, and recalibrated after cleaning to restore normal operation. Poor battery terminal contact in cold weather: Over time, white crystalline particles form on the battery terminals, causing battery leakage and preventing the engine from starting after parking in cold weather. Pouring hot water over the crystalline particles on the terminals can allow normal starting. During maintenance, use sandpaper to remove the white crystalline particles from the terminals and apply grease to resolve the issue. Short circuit in the ignition coil: This can cause difficulty in starting the engine, poor acceleration, black smoke from the exhaust pipe, and a sharp increase in fuel consumption. Replacing the faulty ignition coil can resolve the issue.

What is the fuel consumption of the Ford Kuga 1.5t?

The Ford Kuga 1.5t comes in six models. The 2019 EcoBoost-180-FWD Jingyi Type-National V, FWD Haoyi Type-National V, and FWD Boyi Type-National V are equipped with a 181-horsepower engine, with an NEDC combined fuel consumption of 7.2L/100km. The FWD Jingyi Type-National VI, FWD Boyi Type-National VI, and FWD Haoyi Type-National VI are equipped with a 182-horsepower engine, also with an NEDC combined fuel consumption of 7.2L/100km. The fuel tank capacity is the same across all Ford Kuga 1.5t models. The distance that can be covered on a full tank of fuel is as follows: For models equipped with the 182-horsepower engine, the fuel tank capacity is 60L, allowing a distance of 60/7.2*100=833km on a full tank. For models equipped with the 181-horsepower engine, the fuel tank capacity is also 60L, allowing a distance of 60/7.2*100=833km on a full tank. Vehicle fuel consumption is directly influenced by five major factors: driving habits, the vehicle itself, road conditions, natural wind, and environmental temperature. Specific factors that can increase fuel consumption include: Driving habits: Aggressive driving, such as sudden acceleration, frequent overtaking, or not easing off the throttle before a red light, can increase fuel consumption. The vehicle itself: Vehicles with larger engine displacements generally consume more fuel than those with smaller displacements, as larger displacements typically require more gasoline to generate power. Heavier vehicles also consume more fuel due to the greater driving torque needed. Road conditions: Driving on dirt roads, muddy roads, soft surfaces, or mountainous terrain increases resistance and fuel consumption. Natural wind: Driving against the wind or on windy days increases vehicle resistance and fuel consumption. Low environmental temperatures: When the engine block is cold, injected gasoline does not vaporize easily, requiring more fuel for combustion, thus increasing consumption. Additionally, in cold temperatures, the engine control unit may increase idle speed to warm up the engine, further raising fuel consumption.

How to Fix a Door That Won't Close?

Steps to repair a car door that won't close are as follows: 1. If the door lock is faulty, the locking mechanism of the door may have changed, causing the car door to not close properly; 2. When disassembling the door lock, it is necessary to remove the control device of the door lock and detach the fixing clip between the control device and the lock device; 3. After installing a new lock, repeated adjustments are needed until the door can open and close normally. Additional relevant information is as follows: 1. The central locking switch button in a car is located next to the driver's seat. When the driver presses it, they can control the locks of the other three doors alone, or conversely, each door can be controlled independently. As a control device, a common issue with the central locking system is malfunctioning control, which prevents the doors from locking. If the door lock devices of all four doors can only be opened, it indicates a failure in the central locking system's lock actuator. 2. There are many different products for central locking systems in cars, but the basic components mainly include the door lock switch, door lock actuator, and door lock controller. If the central locking system fails and the doors cannot be locked, it is usually due to a malfunction in the door lock actuator or the door lock controller.
