Is It Necessary to Clean the Fuel Injector? How Often Should It Be Cleaned?

It is necessary to clean the fuel injector, and it is recommended to clean it every 40,000 to 60,000 kilometers. Below is relevant information about fuel injectors: 1. Abnormal Symptoms: Carbon buildup in the fuel injector can lead to poor performance, resulting in accelerated wear of the cylinder and piston rings. This can cause issues such as unstable idling, increased fuel consumption, lack of acceleration power, difficulty starting, and excessive emissions. If not cleaned in time, the fuel injector may become clogged, and in severe cases, it can damage the engine. 2. Cleaning Methods: Cleaning the fuel injector should be done at a professional repair shop or a 4S store. If cleaned at a 4S store, they usually recommend a full set of cleaning services, which includes fuel system cleaning, covering the fuel injector cleaning. This is typically done using a drip method, where a bottle-shaped tool is hung above the engine, and the cleaning agent is poured into the tool. The cleaning agent is then introduced into the engine through a tube to remove carbon deposits. If the fuel injector is cleaned separately at an external repair shop, the cost is relatively cheaper.

What is the difference between Mobil 1 0W30 and 0W40?

The difference between Mobil 1 0W30 and 0W40 is reflected in two aspects. Here are the relevant introductions: 1. Different viscosity: 0W30 and 0W40 represent that the viscosity of the engine oil at 100°C is 30 and 40 respectively. The smaller the number before W in the engine oil grade, the lower the low-temperature viscosity, and the larger the number after W, the higher the viscosity. Generally, the letter W will appear in front of the engine oil used in winter; the smaller the number before W, the smaller the low-temperature viscosity, the better the low-temperature fluidity, and the lower the applicable minimum temperature. For example, 0W has better low-temperature fluidity than 5W. 2. Different applicable conditions: 0W30 is more suitable for urban driving, with better fluidity and lower fuel consumption, while 0W40 is more stable under high-temperature conditions and is more suitable for long-distance or high-speed driving.

Why Does the Mercedes-Benz Defogger Always Blow Hot Air?

Here are the reasons why the Mercedes-Benz defogger blows hot air: 1. Shortest Time: It aims to reduce the temperature difference on both sides of the glass in the shortest time to achieve the purpose of defogging. 2. Simplicity: Blowing hot air is simpler than blowing cold air, as it utilizes the engine temperature without needing to engage the compressor. Below is additional information about the Mercedes-Benz GLC 2021 Dynamic model: 1. Body Dimensions: Its body dimensions are 4764mm in length, 1898mm in width, and 1642mm in height, with a wheelbase of 2973mm and a fuel tank capacity of 66 liters. 2. Powertrain: It is equipped with a 2.0T turbocharged engine, delivering a maximum horsepower of 197PS and a maximum power output of 145kW.

Is it okay to keep the car air conditioning on for a long time?

It is not advisable to keep the car air conditioning on for a long time. Here are the relevant explanations: 1. Impact on the human body: If the vehicle is driven with the air conditioning in recirculation mode for a long time, the oxygen content in the car will decrease, which may cause symptoms such as dizziness and nausea for the occupants. Therefore, if the air conditioning is used for a long time, it is best to switch between recirculation and fresh air modes to maintain air freshness inside the car. Additionally, if the air conditioning temperature is too low and the outside temperature is too high, the sudden change in temperature can easily cause colds for people with poor physical condition. 2. Impact on the vehicle: Although the power source of the air conditioning system is provided by the engine, the working power of the air conditioning cooling fan is driven by the battery. When the vehicle is idling, the electricity generated to charge the battery cannot keep up with the consumption, which may lead to battery depletion and damage its lifespan over time. Moreover, idling with the air conditioning on for a long time may also affect fuel consumption and increase engine carbon deposits.

How to Deal with Refusal to Move a Vehicle?

If someone refuses to move their vehicle, you can call the police or directly arrange for a tow truck to remove the car. When encountering such unreasonable behavior, it's crucial to stay calm, avoid engaging in arguments, and certainly refrain from any physical altercations. During regular vehicle use, it's advisable to leave a contact number for moving the car on your vehicle. If your car blocks someone else's, they can quickly reach you to request moving it. If no contact number is provided, one can check which insurance company issued the compulsory traffic insurance for the vehicle and then call the insurer's customer service. This way, the insurance company can notify the owner to move the car. When using your vehicle, always park in designated spots and avoid random parking, as it's inconsiderate. Parking haphazardly on the roadside can disrupt traffic flow and even cause congestion. If caught by traffic police, you may receive a ticket. While this doesn't result in demerit points, it does incur a fine of 100 yuan. In smaller residential areas where parking is challenging, always leave a contact number for moving the car. This not only facilitates your own convenience but also that of others. If someone calls requesting you to move your car, cooperate positively and avoid refusing to comply.
