How Long Can a Spare Tire Be Used on the Highway?

There is no mileage restriction for using a spare tire on the highway. Definition of a Spare Tire: A spare tire refers to the backup tire for a car, typically matching the specifications of the original tires. However, some vehicles use spare tires with special-colored rims, compact spares, foldable spares, or run-flat tires to remind owners to inspect and replace faulty tires promptly. Types of Spare Tires: There are three types of spare tires: full-size spares, non-full-size spares, and run-flat tires. A full-size spare has identical specifications to the other four tires on the vehicle and can replace any temporarily or permanently unusable tire. A non-full-size spare has a slightly smaller diameter and width compared to the other four tires, making it suitable only for temporary use and exclusively for non-drive wheels. Run-flat tires, also known as safety tires or colloquially as "anti-blowout tires," are officially termed "tire pressure monitoring tires" in the industry.

What is the typical fuel tank capacity of large vehicles?

Large vehicles typically have a fuel tank capacity of 140 liters. The fuel tank capacity measures a vehicle's ability to store fuel, which directly determines the driving range. For two vehicles with identical engines, the one with a larger fuel tank can travel farther. The fuel tank serves to store the working fluid required by the hydraulic system and also functions to dissipate heat, settle impurities, and separate air bubbles from the liquid. During actual refueling, the amount of fuel may exceed the calibrated capacity. This is because the fuel tank capacity specified by manufacturers is measured from the bottom of the tank to the safe fill level, leaving some space between the safe fill level and the tank opening. This space ensures that the fuel can expand when temperatures rise without overflowing. If fuel is filled up to the tank opening during refueling, the actual amount of fuel added may exceed the calibrated tank capacity. To check the remaining fuel level, drivers can observe the fuel gauge on the right side of the dashboard, marked with 'E' and 'F'. When the needle is close to 'E', it indicates low fuel, while proximity to 'F' means the tank is nearly full.

Why is the idle speed high?

Here are the reasons for high idle fuel consumption: 1. The engine's throttle is dirty or malfunctioning. 2. The engine's spark plugs are faulty. 3. Excessive carbon deposits in the engine combustion chamber, intake tract, fuel injectors, or intake manifold lead to incomplete combustion. Below is an introduction to idle speed: 1. Idle state refers to a working condition when the engine is running without load. When the accelerator pedal is fully released while the engine is running, the engine enters idle state. The reason idle speed increases fuel consumption is that the engine is operating in an abnormal state. 2. During idle, the engine speed is very low, intake turbulence weakens, and fuel atomization becomes poor, resulting in incomplete combustion. Additionally, prolonged fuel combustion time and increased cylinder heat dissipation losses also contribute to higher engine fuel consumption. 3. For naturally aspirated engines, the intake pressure is low and airflow is weak during idle, requiring the engine to inject more fuel to maintain higher fuel-air mixture concentration for operation, which also increases fuel consumption. Prolonged idling lowers engine temperature, slowing the evaporation of gasoline entering the valves, leading to carbon deposits.

How Many Degrees to Turn the Steering Wheel Right?

Turn the steering wheel approximately 150 to 160 degrees to the right. The steering wheel is a wheel-shaped device used to control the direction of cars, ships, and airplanes. Below are some relevant details: When holding the steering wheel, both hands should be positioned at the "9:15" position and grip it firmly. While turning the steering wheel, keep both hands on it and rotate up to 180 degrees in either direction. This range of steering is sufficient for most situations. In rare cases, such as making a U-turn on a mountain road or parking, simply repeat this hand-over-hand motion, which is commonly referred to as "full-lock steering." When turning right, there is a frequently overlooked traffic violation: failing to yield to pedestrians. If pedestrians are crossing the road during a right turn, you must stop and wait; otherwise, you may face a fine. Additionally, if a left-turning vehicle approaches while you are turning right, you must yield to it. In the event of a collision, the right-turning vehicle typically bears greater responsibility.

Will Insurance Cover Vehicle Water Damage During a Typhoon?

Insurance will cover vehicle water damage during a typhoon. The premium for water-related damage insurance is not high, and engine damage caused by water accounts for 20% to 30% of the total vehicle value. Regulations on vehicle compensation due to natural disasters: If the vehicle causes personal injury or direct property damage to a third party due to a natural disaster, third-party liability insurance must be activated for claims. Typically, auto insurance has a certain percentage of an absolute deductible, usually around 15%, which the insured must bear themselves. Therefore, when selecting insurance types, special attention should be paid to no-deductible coverage. Solutions for vehicle water ingress: Do not start the engine immediately. Attempting to start the engine at this time can cause water to enter the combustion chamber, leading to bending of the engine connecting rod and, in severe cases, serious damage to components such as the engine block. The correct method for driving through water involves first assessing the depth of the water. If the water does not exceed half the wheel height, it is safe to proceed; otherwise, it is not advisable to continue. Once entering a waterlogged area, reduce speed and drive slowly. For automatic transmission vehicles, use the first gear if possible, ideally entering snow mode to prevent wheel slippage. After exiting the waterlogged area, apply the brakes several times in succession to evaporate the moisture from the brake discs and avoid affecting the vehicle's braking performance.

What Causes the Yellow Engine Light on the Dashboard of a New Car?

After starting the car, if the yellow engine warning light remains illuminated, it indicates that the ECU is alerting you to a fault in the engine, which is abnormal. Below are the reasons why the yellow engine light may be on: 1. Sensor issues. This includes the coolant temperature sensor, crankshaft position sensor, air flow sensor, intake air temperature sensor, oxygen sensor, etc. When these sensors are damaged, have poor connections, or experience signal interruptions, the car's ECU cannot accurately obtain engine data, triggering the engine warning light. 2. Maintenance problems. Poor engine maintenance is the most common cause of the engine warning light turning on. Vehicles have specific maintenance schedules, and if the owner fails to adhere to them, combined with poor driving habits, it can increase the burden on the engine, eventually prompting the yellow warning light. 3. Fuel or oil quality issues. This includes both fuel and engine oil. The fuel used in cars typically has a specific octane rating, and engine oil can be semi-synthetic or fully synthetic. Manufacturers usually recommend specific fuel grades and oil types. Failure to follow these recommendations can lead to engine wear over time. 4. Poor combustion of the air-fuel mixture. Faulty spark plugs, ignition coils, fuel pumps, or clogged fuel lines can all cause poor combustion of the air-fuel mixture in the engine. 5. False alarms. Driving on bumpy roads and experiencing jolts, tampering with engine connectors, or temporary ECU signal interruptions can all potentially trigger the yellow engine light.
