What to Do When the Car Can't Accelerate While Driving?

If the car can't accelerate while driving, it is necessary to check the fuel tank pump to see if it is working properly. Here is a detailed explanation of what to do when the car can't accelerate while driving: 1. Check the fuel tank pump to see if it is working properly. The pump motor will make noise when operating. If the pump cannot supply fuel normally, it will lead to insufficient vehicle power. 2. Check if the gasoline filter is working well and if there is any leakage or blockage. If the leakage is more severe, starting the vehicle may cause it to ignite due to static electricity. 3. Check if the intake pipe is blocked by dirt. Remove the air filter to see if it has water ingress. If necessary, replace the air filter. 4. Check if the valve timing is correct and if the intake and exhaust pipes are tightly sealed. The throttle can be cleaned, or a cleaning-type fuel additive can be added to the fuel to achieve a certain carbon removal effect.

What Causes the Fuel Gauge Needle to Stop Moving?

The fuel gauge needle stops moving due to: 1. Issues with the fuel level sensor; 2. Problems with the fuel gauge circuit. Solutions include: 1. Checking whether the fuel level sensor plug on the fuel tank is loose, oxidized, or burnt, and observing if there is any sticking during the sliding process of the fuel level sensor; 2. Removing the instrument panel and using a multimeter and a pin to locate and test the circuit corresponding to the fuel gauge on the instrument panel. The fuel gauge operates via a float in the fuel tank connected to a metal rod. The end of the metal rod connected to the float links to a movable contact point on a variable resistor. The vertical position changes of the float on the fuel surface in the tank alter the position on the variable resistor via the metal rod. The variable resistor is then connected to the vehicle's fuel gauge, which controls the fuel gauge needle based on the amount of current flowing through the variable resistor.

What are the symptoms of a faulty fuel float?

The symptoms of a faulty fuel float: 1. The car fuel gauge suddenly drops to zero, which is caused by a malfunctioning fuel level sensor. This occurs when the fuel level sensor is not cleaned in time, and over time, it affects normal operation. 2. The fuel gauge remains stuck at a certain position, which happens because the linkage between the fuel level sensor and the fuel float gets stuck, preventing the fuel float from moving up and down normally. This causes the fuel gauge needle to stay fixed in one position, requiring the fuel pump to be removed for servicing. If there are impurities in the gasoline, the fuel level sensor will become contaminated after prolonged immersion, directly affecting the sensor's accuracy. In such cases, it is necessary to clean or replace the fuel float promptly. There is no way to prevent fuel float failure, but choosing higher-quality gasoline can help. Higher-quality gasoline contains relatively fewer impurities, significantly reducing the probability of fuel gauge malfunctions.

What is the normal tire pressure range for the Buick Excelle?

The normal tire pressure range for the Buick Excelle is 2.2-2.5 bar, as long as the tire pressure is within the safe range. Hazards of overinflated tires: Reduced friction and adhesion of the tires, affecting braking performance; causes steering wheel vibration and misalignment, reducing driving comfort; accelerates uneven wear on the central tread pattern, shortening tire lifespan; increases vehicle vibration, indirectly affecting the lifespan of other components; overstretches tire cords, reducing tire elasticity and increasing the load on the vehicle while driving. Hazards of underinflated tires: Increases friction with the road surface, leading to higher fuel consumption; causes heavy steering and misalignment, compromising driving safety; increases movement of tire components, leading to abnormal heat generation from excessive rolling; reduces the functionality of cords and rubber, causing delamination or cord breakage, and excessive friction with the wheel rim, resulting in damage to the bead area and abnormal wear.

What to Do When Tire Pressure Display is Abnormal but Tires Appear Normal?

It could be that the tire is leaking air, but the leakage is not obvious enough to be observed with the naked eye; or the tire pressure system sensor might be faulty, causing a false alarm. What to do if tire pressure is insufficient: If no damage is visible on the car's tires, simply inflate them to the normal pressure and reset the tire pressure system. If inspection reveals that the tire has been punctured, drive to a car repair shop promptly to have it patched before reinflating. If the tire pressure warning reappears some time after inflation without any visible puncture, it might be due to air leakage caused by a deformed wheel rim. It is advisable to check the rim and replace it if necessary. How tire pressure monitoring works: Pressure sensors installed inside the tires measure the air pressure, and a wireless transmitter sends the pressure information from inside the tire to a central receiver module.

What is ETC for vehicles?

ETC is an electronic toll collection system, also known as an automatic road tolling system. It is a road tolling method specifically designed for toll roads, commonly seen on highways, bridges or tunnels with toll policies, and certain sections of city centers, aimed at alleviating urban traffic congestion. According to the State Council's regulations, starting from 2020, vehicles without ETC will not enjoy toll discounts. In the future, only one manual lane will be retained at highway toll stations, and tolls can only be paid through manual lanes. Additionally, newly installed ETC devices cannot be used on highways immediately; they need to be activated first. During free holiday periods, vehicles with ETC can still use highways, and no fees will be deducted when passing through ETC lanes. ETC Deduction Principles: Highways have one or more ETC lanes. Through dedicated short-range microwave communication between the onboard electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane at the toll station, the system uses computer networking technology to settle payments with banks in the background. This allows vehicles to pay tolls without stopping at road or bridge toll stations, all based on the principle of passing first and deducting fees later. Benefits of Installing ETC: Time-saving: Eliminates the hassle of waiting in queues. Green and eco-friendly: Reduces noise and exhaust emissions by allowing vehicles to pass toll stations without stopping, thus lowering pollution. Cost-saving: Reduces vehicle wear and fuel consumption by minimizing frequent starts and brakes. Users also enjoy a 5% discount on toll fees. Improved efficiency: ETC lanes can theoretically increase vehicle passing efficiency by 2-3 times, making traditional ETC systems more advanced, faster, and high-tech. Compared to license plate payment, ETC technology is more mature and advantageous. More policy support: The State Council's "13th Five-Year Plan for the Development of a Modern Integrated Transportation System" explicitly states the goal of "achieving interoperability of transportation cards in key city clusters by 2020 and significantly increasing the proportion of vehicles equipped with ETC." It also sets a target of "50% ETC usage rate for road passenger vehicles by 2020" in the main indicators of the "13th Five-Year" comprehensive transportation development plan. More future possibilities: In addition to continuously improving the convenience of ETC installation and usage rates for passenger vehicles, efforts will be made to promote ETC usage for trucks and explore deeper integration of ETC systems with smart transportation directions such as vehicle-to-vehicle communication and vehicle-road coordination. This will provide comprehensive travel services for vehicle owners, meaning more application scenarios will support ETC usage. ETC Usage Notes: The ETC transaction sensing range is 8 meters. If the vehicle in front stops, maintain a distance of more than 10 meters to prevent automatic sensing from deducting fees for the vehicle in front, especially if it has a faulty or no ETC device. The speed limit for ETC lane recognition is 20 km/h. Excessive speed may prevent the system from reading the vehicle's device information, leading to failed deductions. Unauthorized removal or movement of the OBU device, or detachment or loosening of the ETC electronic tag, will render the tag ineffective. It can be taken to the bank where the ETC card was issued or the highway service office for inspection. If the detachment or loosening is not due to human interference, reactivation is sufficient. When using a debit card linked to ETC, insufficient balance may cause deduction failures. Follow the guidance of on-site staff to use the manual MTC lane and pay via cash or card. Thick car windshields may cause poor sensing. This is particularly important for vehicles that have had their windshields replaced after accidents or for those who have modified their front windshields.
