What are the general items included in car maintenance?

Car maintenance items include: 1. Changing the engine oil and oil filter; 2. Air filter; 3. Fuel filter; 4. Transmission fluid; 5. Tire maintenance. Below is additional information on car maintenance: 1. Major maintenance builds upon regular maintenance, requiring the replacement of the air filter and fuel filter in addition to the engine oil and oil filter. 2. Major maintenance and regular maintenance can be alternated, with intervals varying by car brand, and should follow the manufacturer's recommendations. Engine oil is the lubricant for the engine, and to ensure optimal performance, it should be replaced periodically. The replacement cycle depends on the oil's effective lifespan. During operation, the engine draws in a large amount of air, and the dust in the air can accelerate wear on the piston group and cylinder. The air filter's role is to remove dust and particles from the air, ensuring that sufficient and clean air enters the cylinder.

What Causes Vehicle Shaking at Low Speeds?

Vehicle shaking at low speeds may be caused by the following reasons: 1. A dirty throttle body or excessive carbon buildup in the fuel injectors. A dirty throttle can prevent it from closing properly or cause the idle stepper motor to stick, both of which can result in excessively high engine idle speed. Carbon deposits generated during engine operation can also lead to vehicle shaking. 2. Worn engine mounts. Engine mounts are responsible for absorbing minor vibrations during engine operation. If the mounts are faulty, these vibrations can transfer to the steering wheel and cabin, causing shaking at idle. 3. The engine may experience increased load when electrical systems are turned on, leading to a drop in idle speed. To compensate for the shaking caused by this drop, the engine automatically increases the RPM slightly. 4. When replacing tires or rims, a tire balance should always be performed. Otherwise, uneven weight distribution can easily cause steering wheel shaking. Deformed rims, uneven rim weight distribution, or incorrect rim angles can all cause shaking while driving.

Under what conditions do cars emit the highest levels of carbon monoxide?

Idling with the engine running produces the most carbon monoxide emissions. Principle: When a car engine's combustion chamber operates at high temperatures, it is more prone to producing carbon monoxide. When idling with the engine running but no load, the fuel burns without doing work, causing the combustion chamber temperature to remain high, thus increasing carbon monoxide production. Here are methods to reduce vehicle emissions: 1. Turn off electrical devices after exiting the car: including the radio, air conditioning, and window heating systems. 2. Proper tire pressure saves fuel: Insufficient tire pressure shortens tire lifespan. Tests show that maintaining manufacturer-recommended tire pressure can reduce fuel consumption by approximately 3.3%. 3. Accelerate gently: A single hard acceleration versus gentle acceleration at the same speed can result in a 12mL difference in fuel consumption, leading to an extra 0.4g of CO2 emissions per kilometer.

How to Shift Gears at a Red Light in an Automatic Transmission Car?

When waiting at a red light in an automatic transmission car, the appropriate gear to shift into depends on the duration of the red light. The shifting recommendations are as follows: 1. If the red light is less than 30 seconds, it is recommended that the driver simply keep their foot on the brake. 2. If the red light lasts between 30 seconds and 1 minute, the driver should shift into N (Neutral) gear and engage the handbrake. 3. For red lights longer than 1 minute, it is advisable to shift into P (Park) gear and engage the handbrake. Below are some general driving tips for automatic transmission cars: 1. Shifting gears at a red light: For short red lights, it is recommended to shift into P or N gear for lower fuel consumption; on a slope, shifting into P gear is advisable; on flat roads, remember to engage the handbrake when in N gear to prevent accidents. 2. Starting the car in P gear: When starting the car, shifting from P to D gear passes through R (Reverse) gear, which can cause a reverse impact on the transmission, potentially damaging it over time and harming the vehicle.

How long does the battery of an ETC device last?

Generally, the battery of an ETC device can last for 3 years under normal usage. For solar-powered ETC devices that are not frequently used, it is recommended to charge them every 3 months to prevent natural discharge of the internal battery. The ETC device has an internal battery and is charged externally via solar power, so it does not require regular charging. ETC stands for Electronic-Toll-Collection, which means electronic toll collection system. To apply for an ETC, the following documents are required: the vehicle owner's valid ID card and vehicle registration certificate (original and photocopy). If the application is handled by a proxy, the proxy's valid ID card is also needed. The photocopy of the vehicle registration certificate should include the page with the most recent annual inspection stamp. Additionally, a bank card for deducting highway tolls is required. Applicants must be between 18 and 60 years old, and the vehicle must be registered under an individual's name. For company vehicles, the required documents include: a letter of introduction from the vehicle owner (with official seal), a photocopy of the organization code certificate or business license (with official seal), the proxy's original ID card, the original vehicle registration certificate, and the vehicle that needs to be equipped with ETC. How ETC works: The vehicle-mounted electronic tag installed on the windshield communicates with the microwave antenna in the ETC lane at the toll station. Using computer networking technology, the system settles the payment with the bank in the background, allowing vehicles to pass through highway or bridge toll stations without stopping to pay the toll. Benefits of installing ETC: Time-saving: Eliminates the hassle of waiting in line. Green and eco-friendly: Reduces noise and exhaust emissions by allowing vehicles to pass through toll stations without stopping. Cost-saving: Reduces vehicle wear and fuel consumption by minimizing the frequency of starting and braking. Users can also enjoy toll discounts. Efficiency improvement: ETC lanes can theoretically increase traffic efficiency by 2-3 times, making traditional ETC systems more advanced and high-tech. Compared to license plate payment, ETC technology is more mature and advantageous.

What Are the Benefits of Antifreeze?

Antifreeze prevents the coolant from freezing and cracking the radiator or damaging the engine cylinder block or head when the vehicle is parked in cold winter conditions. Antifreeze should not be diluted with water. As an alcohol-based chemical reagent, antifreeze provides freeze and rust protection, and adding water alters its properties, reducing its effectiveness. Functions of Antifreeze: Antifreeze is a coolant containing special additives, primarily used in liquid-cooled engine cooling systems. It offers excellent performance in preventing freezing in winter, boiling in summer, and resisting scale and corrosion year-round. Composition of Antifreeze: The main components of antifreeze are 50% purified water, 40% methanol, and 10% other substances. Types of Antifreeze: Antifreeze is generally categorized into three types: ethanol-water, glycerol-water, and ethylene glycol-water. Can Different Antifreezes Be Mixed? Only antifreeze of the same brand should be used. Different brands may have varying production formulas, and mixing them could cause chemical reactions between additives, rendering them ineffective.
