Alcohol can be used to disinfect the interior of a car, as it has sterilizing and disinfecting properties. However, it is recommended to use a wiping method instead of direct spraying. Precautions for using alcohol to disinfect a car include: 1. Alcohol is a flammable and explosive product, so it should be wiped dry immediately after spraying; 2. Ensure good ventilation by opening the car windows, and try to spray on the surface of objects, avoiding hidden or hard-to-reach areas inside the car; 3. After disinfecting the car, avoid smoking inside or closing the windows, as rising temperatures can reach the ignition point of alcohol, increasing the risk of explosion or fire; 4. After wiping with alcohol, special attention should be paid to leather seats, as they may be damaged.

I did this last time when there was a strange smell in my car, and it almost caused a disaster. While 75% alcohol can indeed kill germs, spraying it directly in the car is like planting a time bomb. Alcohol vapor is highly flammable in an enclosed space, and even static sparks can crackle when opening the car door after wiping the steering wheel with alcohol. Moreover, the genuine leather seats and plastic dashboard in our cars can turn white and crack after alcohol spraying—my car’s navigation screen’s touch layer was ruined this way. Now, I’ve switched to using automotive disinfectant wipes for spot cleaning and always open the windows immediately afterward. If deep disinfection is necessary, I’d rather spend a bit more for professional ozone sterilization, which is safer and can also treat hard-to-reach areas like the AC ducts.

Is a tire pressure of 2.2 a bit low in summer?

Tire pressure of 2.2 is slightly low. Here is relevant information about tire pressure: 1. Function: Tire pressure, strictly speaking, refers to the air pressure inside the tire. In terms of car maintenance, the engine is the heart of the car, and damage to the engine will lead to the end of the car's life. Similarly, tire pressure is the blood pressure of the car, and the level of tire pressure plays a crucial role in the performance and power of the car. 2. Indicator: Tire pressure is an indicator of the car's load capacity. The load capacity of the car depends on the level of tire pressure. According to the relationship between the tire's load index, tire pressure, and load capacity, the higher the tire pressure, the greater the load capacity; the lower the pressure, the smaller the load capacity.

How to Turn On the Heater in the 10th Generation Civic?

The method to turn on the heater in the 10th generation Civic is to open the air conditioning system and then adjust the temperature setting higher using the temperature control knob. The 10th generation Civic is equipped with an automatic temperature control air conditioning system. The air conditioning circulation system consists of major components such as the compressor, condenser, expansion valve, and evaporator. The refrigerant circulates within the system, absorbing heat from the car's interior through the principle of heat transfer in the evaporator to achieve cooling. The heater system operates on a different principle from the air conditioning system. The heater utilizes the temperature of the coolant from the engine's cooling system, and a blower transfers heat from the heater core to the interior. Therefore, turning on the heater does not require activating the air conditioning. The 10th generation Civic has a body length, width, and height of 4649mm, 1800mm, and 1416mm respectively, with a wheelbase of 2700mm.

What does the ECO button in a car mean?

ECO refers to the car's economic driving mode. ECO is an English abbreviation formed from the words Ecology (environmental protection), Conservation (energy saving), and Optimization (power). The Eco mode is further divided into active Eco driving mode and non-active Eco driving mode. When the Eco indicator light on the dashboard illuminates, it indicates that the vehicle's economic mode has been activated. Eco mode can be either active or non-active. The difference lies in the fact that the active mode has its own dedicated button, allowing the driver to choose whether to enable it. When the driver presses the Eco mode switch, the dashboard indicator light immediately turns on, and the vehicle automatically begins adjusting settings such as throttle opening, transmission shift logic, and air conditioning output power. Non-active Eco mode does not have a dedicated button. When the Eco indicator light on the dashboard illuminates, it serves merely as a reminder function. The Eco system automatically evaluates your driving behavior. If your current driving operation achieves the optimal fuel supply, the dashboard will simultaneously display the Eco indicator light. Most vehicles employ the active Eco driving mode, meaning they have a dedicated switch button. Therefore, during daily driving, the Eco mode can generally be enabled. However, it is unnecessary to activate Eco mode when driving at speeds exceeding 120 km/h, during idle parking, in N/P gear, or in manual mode—especially when climbing hills. Doing so would not only fail to demonstrate the fuel-saving characteristics of Eco mode but could also negatively impact the vehicle's power. Additionally, the Eco mode typically becomes ineffective under the following circumstances: When the vehicle speed exceeds 120 kilometers per hour, the car prioritizes speed, causing the Eco mode to automatically deactivate. During idle parking or when in N/P gear or manual mode, the Eco mode may also become ineffective. When high torque output is required, such as when climbing a hill, the engine control unit prioritizes ensuring sufficient power to drive the vehicle, and the Eco mode will not function in such scenarios.

How to Prove Your Vehicle's Color Modification?

After completing the color modification, it is essential to obtain a receipt or invoice from the modification shop. When questioned by traffic police, proactively providing this document usually avoids complications. If unsure whether the modified color complies with filing standards, it's advisable to first call or visit the local vehicle management office for clarification. Generally, as long as the color isn't unconventional like chameleon or electroplated, it can usually be filed. Below is additional information: 1. Regulations on vehicle color modification: According to the relevant provisions of the "Road Traffic Safety Law Implementation Regulations", vehicle color can be changed. The body, frame, engine, or entire vehicle can also be modified if they are damaged and unusable. However, other vehicle components are prohibited from unauthorized modifications. Regarding vehicle colors, three types cannot be approved: red, reserved for firefighting; yellow, for engineering rescue; and white upper with blue lower, for national administrative law enforcement. For color modifications, relevant documents must be submitted to the vehicle management office for change registration within 10 working days post-modification. Failure to register the color change as required incurs a 200 yuan fine. 2. Documents required for color modification: Materials needed for the color change procedure include: original "Motor Vehicle Change Registration/Record Application Form", original and copy of the vehicle owner's identity proof, vehicle license, original and copy of the vehicle registration certificate, original vehicle inspection record form (with standard photos of the vehicle after color change and frame number imprint), one standard photo of the vehicle after color change. If a friend is handling the process on your behalf, their ID must also be brought.

What is the displacement of 230tsi?

230tsi is a 1.4-liter displacement. The meaning of 230tsi is an engine model with TSI technology and a torque of 230N·m. TSI stands for Turbocharged Stratified Injection, and 230tsi represents models equipped with the low-power version of the 1.4-liter turbocharged engine. This is Volkswagen's tail badge labeling method. Volkswagen's labeling format is 'Torque grade marker value + engine technology type.' Volkswagen has divided torque into five grades, with each grade differing by 50N·m. Each torque grade uses a 'marker value,' which is derived by rounding the average torque value of that grade. For example, the marker value for the 200-250N·m torque grade is 230. Currently, there are five grades: 180, 230, 280, 330, and 380, corresponding to Volkswagen's 1.4, 1.8, and 2.0-liter displacement engines. Displacement is a specialized term in hydraulic transmission, referring to the volume of fluid inhaled or expelled per stroke or cycle. Generally, a larger displacement means the engine releases more energy per unit time (converting chemical energy from fuel into mechanical energy), resulting in better performance. Therefore, SUVs and sports cars usually have relatively larger displacements. Most domestically produced cars have a model number consisting of pinyin letters and Arabic numerals on the rear. Some domestically produced cars do not have this model number, but their displacement is usually indicated on the body or rear. Take the Volkswagen Lamando as an example: The Lamando uses two engines: one is the low-power version of the 1.4-liter turbocharged engine, and the other is the high-power version of the 1.4-liter turbocharged engine. The model equipped with the low-power 1.4-liter turbocharged engine is the 230tsi, with a maximum torque of 225 N·m. The model equipped with the high-power 1.4-liter turbocharged engine is the 280tsi, with a maximum torque of 250 N·m. Volkswagen also has 330tsi and 380tsi models. The 330tsi indicates models with the low-power 2.0-liter turbocharged engine, while the 380tsi indicates models with the high-power 2.0-liter turbocharged engine. Volkswagen also has 200tsi models, which indicate models equipped with the 1.2-liter turbocharged engine. Volkswagen's tail badges are quite easy to distinguish—the larger the number, the stronger the power.

There are national regulations regarding vehicle dimensions. According to the national standard 'GB1589-89', the total width of a vehicle does not include side mirrors. The limitation on vehicle width is to provide sufficient lateral clearance for overtaking between adjacent lanes. In other words, the significance of vehicle width data in national standards is to ensure enough space during overtaking, preventing accidents due to excessive width or situations where road markings are narrower than the vehicle's width. Additionally, national regulations stipulate that the total width of a vehicle must not exceed 2.5m to meet the usage requirements of public roads.
