How to Solve the Problem of Increasing Car Fuel Consumption?

Here are the solutions to the problem of increasing fuel consumption: 1. Regular maintenance: Perform regular maintenance every 6,000 to 10,000 kilometers to reduce the accumulation of carbon deposits in the engine; when refueling, choose gas stations with good fuel quality to prevent the intake manifold walls from becoming rough, which affects the intake efficiency and the quality of the air-fuel mixture, leading to increased carbon deposits. 2. Regular carbon deposit cleaning: Perform periodic carbon deposit cleaning every 40,000 to 50,000 kilometers, such as using drip cleaning, foam cleaning, hydrogen-oxygen carbon removal machines, or manual disassembly and cleaning. 4. Regular replacement of spark plugs: The purpose of regularly replacing spark plugs is to use high-voltage electricity to generate sparks to ignite the air-fuel mixture. If damaged, the ignition energy will decrease, causing uneven combustion of the air-fuel mixture, which slows down acceleration and increases fuel consumption. 5. Frequently check tire pressure and tire wear: Frequently check tire pressure and tire wear. If the tire pressure is too low, the friction between the tires and the ground will increase, leading to greater resistance and higher fuel consumption. The normal tire pressure is around 2.5 bar, and it can be appropriately reduced in summer.

What is the appropriate tire pressure for driving on highways in winter?

For driving on highways in winter, a tire pressure of 2.6 bar is appropriate. Strictly speaking, tire pressure refers to the air pressure inside the tire. The standard tire pressure for cars is 240-250 kPa, where 1 kPa equals 0.01 bar, according to the international GBT2978-2008 standard. The tire pressure for different types of tires is as follows: Standard tires: 2.4-2.5 bar; Reinforced tires: 2.8-2.9 bar; Maximum pressure: should not exceed 3.5 bar. Normal tire pressure in winter: In winter, the tire pressure should be based on the standard tire pressure of the car, with an appropriate increase of about 0.2 bar. Normal tire pressure in summer: Generally, the lower limit of the standard tire pressure for car tires is sufficient. For example, the lower limit for standard tires is 2.4 bar. If the car is often parked outdoors, the tire pressure can generally be about 0.1 bar lower than the standard to prevent tire blowouts due to high temperatures.

Can I Start Learning Subject 2 Only After Passing Subject 1?

Yes, you can only start learning Subject 2 after passing Subject 1. According to the "Regulations on the Application and Use of Motor Vehicle Driving Licenses," the waiting period between Subject 1 and Subject 2 varies depending on the type of license. For a C-class license, you can schedule Subject 2 10 days after passing Subject 1, while for A and B-class licenses, you must wait 20 days. This provides ample time to prepare for Subject 2. Each time you schedule Subject 2, you have two exam attempts. If you fail the first attempt, you can retake it once for free. If you do not take the retest or fail the retest, the exam session ends. Within the validity period of your driving permit, you can schedule Subject 2 no more than five times. If you fail the fifth attempt, all previously passed subjects will be invalidated. To continue learning, you must restart the process from Subject 1. For example, the C1 license Subject 2 exam includes: Completing designated driving tasks within a specified area; demonstrating proficiency in vehicle control; and assessing spatial judgment skills. Subject 2, also known as the "small road test," consists of five mandatory tasks: reverse parking, parallel parking, hill start, right-angle turn, and curve driving. Some regions include a sixth task: highway toll card collection. Subject 2 Exam Tips: After getting into the car, adjust the seat and mirrors to a comfortable position and fasten your seatbelt. For parallel parking, find the correct angle quickly, turn the steering wheel promptly, and coordinate with the car's speed. During hill starts, remember to engage the handbrake, signal left, release the handbrake, and balance the clutch and throttle to avoid stalling or rolling back. For right-angle turns, react swiftly after identifying the turning point and match the car's speed to prevent misalignment. For curve driving (S-turn), slow down. Those with good driving sense can pass smoothly in one go. When reversing into a parking space, control the speed, identify reference points, and make minor adjustments if needed by checking the mirrors. The driving test consists of three subjects: Subject 1 (traffic laws and regulations), Subject 2 (field driving skills), and Subject 3 (road driving skills and safe driving knowledge). The safe driving knowledge test is conducted after Subject 3, often referred to as "Subject 4," though this term is unofficial and not mentioned in the official regulations (Ministry of Public Security Order No. 123).
