There are multiple reasons for high fuel consumption in cars. Here is relevant information about high fuel consumption in cars: 1. Poor driving habits: sudden acceleration, sudden braking, coasting in neutral, and mismatched speed and gear. 2. Carbon deposits and electronic control system failures: carbon deposits on the throttle body, idle valve, and fuel injectors, as well as inaccurate signals from the oxygen sensor, intake pressure sensor, and coolant temperature sensor. 3. Lack of timely vehicle maintenance: failure to replace air filters, fuel filters, spark plugs, and clutch plates on time can also lead to increased fuel consumption. 4. Methods to check the causes: check whether the tire pressure meets the standard, the degree of tire wear, whether the wheels rotate normally, and the condition of the bearings and brake system.

My car consumes a lot of fuel when I drive, mainly because I have a habit of rapid acceleration and sudden braking, especially during traffic jams, where frequent engine starts increase fuel consumption. Last time during peak hours in the city, a full tank only lasted 200 kilometers. Also, idling for too long, like when waiting for someone with the air conditioning on, wastes fuel unnecessarily. Using the air conditioning in summer also increases fuel consumption by 10%. It's recommended to use the recirculation mode and reduce the fan speed to save more. Heavy load is also crucial. Last year when I moved with a fully loaded car, fuel consumption surged by 15%. Driving with lighter loads is much better. Low tire pressure increases rolling resistance, so I regularly check and maintain it at the recommended value of 2.5-3 bar. Developing smooth driving habits and planning routes reasonably can save a lot of money and reduce anxiety.

How to install ETC for private cars?

ETC can be processed at bank outlets or highway service areas. Professional staff will install the ETC device at the service point. Required documents include the original and photocopy of the vehicle owner's valid ID and vehicle license. If processed by an agent, the agent's valid ID is also required. The photocopy of the vehicle license should include the page with the most recent annual inspection seal. A Postal Savings credit card application form is needed to bind with the ETC card. After obtaining the credit card, swipe it twice and present the POS slip at designated postal outlets to receive and install the ETC onboard unit for free, with no additional charges. Applicants must be aged 18-60 and own the vehicle. ETC stands for Electronic-Toll-Collection, meaning electronic toll collection system. Here are precautions for ETC installation: Do not obstruct vision - best installed behind the rearview mirror: Many car models have steeply angled windshields that reduce driver visibility. Installing ETC without considering this may increase blind spots. Install it on the right side behind the interior rearview mirror to avoid vision obstruction. Do not affect charging: The ETC electronic tag consumes power but generally doesn't require charging or battery replacement as it has a built-in solar panel. Avoid installing it on the windshield's blackened areas or positions that might block the solar panel. Do not remove arbitrarily after installation: The adhesive contains an anti-tamper rod connected to a switch. When installed, the windshield presses this rod in. Removal causes the rod to pop out and trigger the switch, locking the device. Unlocking requires visiting an ETC service center. This prevents multiple vehicles sharing one device. ETC usage notes: The ETC sensing range is 8 meters. Maintain over 10 meters distance from the vehicle ahead to avoid accidental payment for others due to their faulty ETC. The ETC lane recognition speed limit is 20 km/h - excessive speed may cause reading failure. Insufficient balance on debit cards linked to ETC will also cause payment failure.

Can I turn left if the light turns red after entering the waiting area?

No. When in the left-turn waiting area, generally both directions of traffic have a green light for going straight, and the left-turn arrow is red, so you cannot turn left. You must wait until the left-turn signal turns green to proceed. If the left-turn signal changes from green to red, vehicles intending to turn left must stop before the stop line, but vehicles that have already crossed the stop line and entered the waiting area must continue to turn left and should not remain in the waiting area. More details are as follows: 1. Drivers should be reminded that the left-turn waiting line is not a "stop line." If both the straight and left-turn signals are red, all vehicles must wait behind the previous stop line. 2. If a vehicle has just crossed the stop line when the light turns red but stops immediately, this will not be penalized as running a red light. However, if there is noticeable movement after crossing the line, penalties will apply. 3. The three photos taken by traffic cameras for running a red light are: the vehicle crossing the stop line, followed by two more showing the vehicle moving to the center of the intersection and reaching the opposite side of the intersection.

What are the differences between China IV and China V emission standards?

The differences between China IV and China V emission standards for vehicles are: different nitrogen oxide (NOx) emission standards, different non-methane hydrocarbon (NMHC) emission standards, and different particulate matter (PM) concentration emission standards. Different nitrogen oxide (NOx) emission standards: The China IV NOx emission standard is 0.08; the China V NOx emission standard is 0.06. Different non-methane hydrocarbon (NMHC) emission standards: China IV has no NMHC emission standard; the China V NMHC emission standard is 0.068. Different particulate matter (PM) concentration emission standards: China IV has no PM concentration emission standard; the China V PM concentration emission standard is 0.0045. Methods to distinguish between China IV and China V vehicles include: checking the vehicle fuel consumption label; inspecting the vehicle nameplate; and examining the vehicle engine model. The China V motor vehicle pollutant emission standard, known as the 'China V standard,' has an emission control level equivalent to the European Union's fifth-stage emission standard currently in effect. The EU has been implementing this standard since 2009, imposing very stringent limits on vehicle emissions such as nitrogen oxides, hydrocarbons, carbon monoxide, and suspended particles. From China I to China V, each upgrade in the standard reduces vehicle pollution by 30% to 50%.

Where to Install Car Door Vibration Damping Pads?

Door vibration damping pads should be installed at the closest point between the door and the car body panel when the door is closed. These pads are harmless to the door. Firstly, they are made of rubber material and are attached to the car body using adhesive, which is generally very mild and won't damage the car's surface. Here's some relevant information: Function: Car noise and vibration have always been the top enemies of driving comfort, so many car owners choose to install door vibration damping pads on their vehicles to enhance driving comfort and protect the doors. These pads prevent door friction during vibrations, which can cause loosening and noise, and also avoid paint chipping when doors are closed forcefully. Precautions for using car doors: Avoid using excessive force when closing the door, as this can damage the door's sealing strip and even cause deformation, making it difficult to open or close the door properly. Additionally, pay attention to the door's limiter; if it shows any abnormalities, promptly visit a repair facility for inspection. Always check your surroundings before opening the door when exiting the vehicle to ensure safety.

What is the problem when the car won't start?

The reasons why a car won't start generally include: a dead battery or an empty fuel tank; incorrect gear position or a locked steering wheel preventing startup; automotive circuit or electronic failures, such as damaged spark plugs, blown fuses, or fuel pump malfunctions. Fuel quality issues, such as using poor-quality fuel that prevents the engine from operating properly, etc. Below are specific causes: Human operational reasons: dead battery, empty fuel tank, incorrect gear position. For automatic transmission cars, the gear must be in P (Park) or N (Neutral) to start; if it's in R (Reverse) or D (Drive), the car won't start. Some manual transmission cars won't start if the clutch isn't depressed. Vehicle usage reasons: improper fuel, lack of antifreeze, excessive carbon buildup. A dead battery could be due to leaving headlights on for a long time, causing power drain, or the battery's lifespan has expired. Installing xenon headlights, high-power audio systems, or DVD players can also lead to vehicle circuit failures.
