What is Gasoline Additive?

Gasoline additive, short for fuel additive, is designed to compensate for the inherent quality issues of fuel and the limitations in automotive mechanical manufacturing. It enables gasoline engines to overcome the cold shock effect and crevice effect, serving to remove carbon deposits from intake valves and fuel injectors. The composition and functions of gasoline additives can be categorized into: 1. Maintenance-type fuel additives: They envelop carbon deposit particles formed through oxidative condensation reactions at high temperatures, preventing them from growing larger; 2. Cleaning-type fuel additives: When carbon deposits accumulate on the surfaces of fuel injectors and intake valves, cleaning-type additives utilize surfactants to penetrate the pores of carbon deposits, disrupt their structure, segment and envelop the carbon particles, and dissolve them for expulsion through exhaust emissions.

My car used to always lack power, and a friend recommended gasoline additives, saying they are chemical substances added to gasoline that can clean the inside of the engine, remove carbon deposits and sludge. After using them, the car runs much smoother, accelerates more powerfully, and even the fuel consumption has decreased a bit, saving money in the long run. Some premium additives can also increase the octane rating, making combustion more complete and reducing emissions. Now, during maintenance, I regularly add them, choosing reliable brands and not going for cheap options to avoid harming the engine. Small car maintenance can't do without it, especially for older cars.

Gasoline additives are liquid chemicals mainly categorized into cleaning and performance types. Cleaning types remove carbon deposits from fuel injectors to prevent clogging, while performance types improve combustion efficiency. I do a lot of city driving with frequent starts and stops, leading to rapid carbon buildup, so adding additives helps keep the engine clean. Many modern cars come with built-in additives, but extra doses can enhance the effect. Be sure to follow the dosage instructions and avoid overuse. Regular use can extend engine life, and adding some before long trips is especially beneficial for stability.

When on a tight budget, fuel additives are a real money-saver. After adding them, fuel efficiency improves, saving a few cents per kilometer, which adds up to significant savings over a year. They clean the internals, reducing repair costs, especially for cars over ten years old, preventing stalling issues caused by carbon buildup. I bought cheap additives online, and they worked well—the car runs smoother now. Maintaining a car requires careful budgeting, and this is a small investment with big returns.

What Are the Reasons for a Car Not Starting in Winter?

In winter, if a car fails to start, it can be analyzed from four aspects: spark plugs, oxygen sensors, throttle and intake passages, and fuel injectors: 1. Spark Plugs: During operation, especially in winter, symptoms like reduced power, engine shaking, and difficulty starting may occur. This could be due to carbon deposits on the spark plugs or loose ignition coils, leading to starting difficulties. Simply replacing the spark plugs can resolve this issue. 2. Oxygen Sensor: If the oxygen sensor is faulty, it can cause inaccurate fuel injection, resulting in a suboptimal air-fuel ratio in the engine. A significant deviation from the optimal ratio can make the engine hard to start. 3. Throttle and Intake Passages: Dirty throttle and intake passages can also lead to carbon buildup and blockages. In summer, this might manifest as noticeable shaking at idle, while in winter, it can cause difficulty starting the engine. 4. Fuel Injectors: Carbon deposits clogging the fuel injectors or impurities blocking the fuel pump's filter can both lead to the car not starting or having difficulty starting in winter.

Does an eight-year-old car require an annual inspection?

An eight-year-old car requires an inspection every two years. The Ministry of Public Security issued new regulations for vehicle inspections in 2021, stipulating that for vehicles older than 6 years but less than 10 years, the inspection cycle has been relaxed from once a year to once every two years. This means that private cars only need to undergo two on-site inspections within 10 years, specifically in the 6th and 8th years. Below is relevant information: Introduction: Vehicle inspection refers to a mandatory test for all vehicles that have obtained official license plates and registration certificates. It is equivalent to an annual physical examination for the vehicle based on the technical conditions for safe operation of motor vehicles. Vehicle inspections can promptly eliminate potential safety hazards, encourage enhanced vehicle maintenance, and reduce the occurrence of traffic accidents. Purpose: Vehicle inspections can promptly eliminate potential safety hazards, encourage enhanced vehicle maintenance, and reduce the occurrence of traffic accidents.

How to Deal with ETC Overcharging Issues?

Solutions for ETC overcharging issues: Visit the bank for consultation and resolution. First, print out the transaction details and travel records of your personal ETC card, then carefully verify each fee item. If incorrect charges are confirmed, you can request a refund from the bank. Precautions for ETC usage: The ETC transaction sensing range is 8 meters. When encountering a stationary vehicle ahead, maintain a distance of over 10 meters to prevent automatic fee deduction for the vehicle in front, in case its ETC device is faulty or absent. The ETC lane recognizes vehicle speeds up to 20km/h. Speeding may result in failure to read the vehicle's device information and unsuccessful fee deduction. Unauthorized removal or movement of the OBU device, detachment, or loosening of the ETC electronic tag can render the tag invalid. It can be taken to the bank where the ETC card was issued or to a highway service center for inspection. If the detachment or loosening is not due to human intervention, reactivation may suffice. When using a debit card linked to ETC, insufficient balance can lead to fee deduction failure. Follow the guidance of on-site staff to use the manual MTC lane with cash or card payment. Excessively thick car windshields may cause poor signal reception. This is particularly important for vehicles that have had their windshields replaced after accidents or for those with modified front windshields.

What are the dimensions of a bus parking space?

Bus parking space dimensions are as follows: Minibus (small space) parking space: width 2.5 meters, length 5.5 meters. Coach parking space: width 3.5 meters, length 12.5-14.5 meters. Parking spaces can be categorized by size and arrangement. Parking spaces are divided into two types by size: Large parking space: length 15.6 meters, width 3.25 meters, suitable for medium and large vehicles; Small parking space: length 6 meters, width 2.5 meters, suitable for small vehicles. Parking spaces are divided into three types by arrangement: Parallel parking space: standard length of 6 meters, width of 2.5 meters. Angled parking space (30°, 45°, 60° angle): diagonal length of 6 meters, width of 2.8 meters, with a perpendicular distance between two diagonal lines maintained at 2.5 meters. Perpendicular parking space: length ≥5 meters, usually set at 6 meters, width of 2.5 meters, with 2.5x5.3 meters being the optimal standard parking space size. Large vehicle parking spaces should not use angled or perpendicular arrangements.

Does Heavy Rain Affect Cars?

Heavy rain has little impact on cars, but it is still necessary to pay attention to waterproofing, otherwise the car may malfunction and become a flooded vehicle. The following is a detailed introduction about flooded vehicles: Overview: A flooded vehicle refers to a vehicle that has been soaked in water, generally meaning that the engine and transmission have been submerged, with the water depth exceeding the wheels and body seats, and the bottom components of the body have been in prolonged contact with water. The risk factor is very high, as the electrical circuits can easily cause short circuits, fires, and other accidents. Others: "Flooded vehicles" can be repaired to a certain extent, but even after repair, there are serious hidden dangers. The longer the soaking time, the higher the probability of malfunctions, and they cannot be completely repaired.
