330T Passat requires approximately 4.5L of engine oil for an oil change. Below are the relevant introductions about engine oil: 1. Reduce wear: There is rapid relative sliding between the piston and cylinder, as well as between the main shaft and bearing shells. To prevent excessive wear of parts, an oil film of sufficient thickness needs to be established between the two sliding surfaces to separate the relatively sliding parts and reduce wear, thereby extending mechanical life. 2. Cooling: Engine oil helps the radiator cool the engine by dissipating heat away from the engine. 3. Sealing and leak prevention: Engine oil can form a sealing ring between the piston ring and piston, reducing gas leakage and the entry of pollutants. 4. Shock absorption: When the pressure at the engine cylinder port rises sharply, it suddenly increases the load on the piston, piston chips, connecting rod, and crankshaft bearings. This load is transmitted and lubricated through the bearings, cushioning the impact load.

What is the fuel tank capacity of Jinbei Haise?

The fuel tank capacity of Jinbei Haise is 55 liters. It is a microvan under Huachen Renault Jinbei. Among similar vehicles, the Fengjing G7 has a fuel tank capacity of 65 liters, while Jinwei has a fuel tank capacity of 55 liters. If the owner wants to know the remaining fuel level, they can observe the fuel gauge on the right side of the dashboard, which is marked with E and F. When the pointer is close to E, it indicates that the fuel is almost empty, and when it is close to F, it means the fuel level is sufficient. The maintenance of the fuel tank is as follows: Drain accumulated water and sediment from the fuel tank, and check for any fuel leakage at the fuel pipe joints and switches. For fuel tank caps equipped with air valves and steam valves, also check if the vent holes are clear. The filter screen at the fuel filler port should remain intact to prevent impurities from entering the fuel tank during refueling and clogging the fuel lines. The sealing gasket on the fuel filler cap should also be intact to prevent fuel from spilling out during driving.

How to Deal with Delayed Car Delivery by a 4S Store?

If a 4S store delays car delivery, compensation can be claimed according to the contract. Below are the relevant methods for complaint and compensation claims: 1. Negotiate with the 4S Store: Engage in negotiations with the 4S store and demand that they deliver the car within a specified time. Generally, to minimize damage to their external image and avoid paying double the deposit, 4S stores will strive to deliver the vehicle as soon as possible or offer some form of compensation. 2. Telephone Complaint: Call the manufacturer to file a complaint. Since car manufacturers conduct strict qualification reviews and operational assessments of 4S stores, and 4S stores largely represent the brand image of the manufacturer, most 4S stores will not dare to neglect such reasonable claims when the manufacturer is involved. 3. Call 12315: Dial the 12315 hotline to file a complaint and seek assistance from the Market Supervision Bureau. Specialists will help mediate, and under circumstances where the 4S store is at fault, they usually won't act too arrogantly, making the probability of successful mediation very high. 4. File a Lawsuit Against the 4S Store: Collect all necessary evidence and notify the 4S store in writing, setting a deadline for car delivery. Otherwise, the contract will be terminated, and double the deposit will be claimed as compensation. If the 4S store still fails to fulfill its promise, legal action may be the only option to protect one's legitimate rights and interests through the law.

What are the solutions for clogged sunroof drainage holes in the Magotan?

The solutions for clogged sunroof drainage holes in the Magotan are as follows: 1. Air Pressure Method: Use an air gun to direct high-pressure airflow into the drainage holes of the two front drainage pipes inside the sunroof to clear the blockage. 2. Flushing Method: Use a syringe to flush the drainage pipe, which has proven to be very effective and simple in practice. Functions of the car sunroof: 1. Opening the sunroof in traffic jams prevents exhaust fumes from entering the car: During traffic jams, all vehicles are stationary, and exhaust fumes inevitably disperse in the air. Opening the sunroof and closing the side windows will expel the exhaust fumes inside the car and complete the exchange of fresh air through the car's air conditioning filter. 2. Opening the sunroof after exposure to sunlight balances the interior temperature: In the hot summer, after the car has been exposed to the sun, the interior temperature becomes very high. Opening the sunroof promptly is advisable. Experiments have shown that the ideal way to achieve a balanced interior temperature is to turn on the air conditioning and open the sunroof, ensuring optimal oxygen supply for the comfort and safety of the driver and passengers. 3. Opening the sunroof at high speeds reduces wind noise: At high speeds, drivers are often troubled by the noise and side wind blowing on their faces when the side windows are open. Opening the sunroof and closing the side windows can effectively prevent such issues.

Is Engine Oil Cleaning Fluid Useful?

Engine oil cleaning fluid is useful. Here are the reasons why cleaning fluid should be used: 1. Older car engines have significant wear and more sludge. When cleaning agents are used, the sludge is effectively removed. 2. The sealing performance between the engine piston and cylinder wall may not be as good as before, and the engine oil passages become clearer: For vehicles with normal wear, cleaning is beneficial as it prevents increased sludge buildup, which can lead to greater engine wear. Regular maintenance based on time and mileage, using branded and guaranteed engine oil and oil filters, will minimize sludge formation, as engine oil itself contains cleaning additives.

What is the tariff on imported cars?

Currently, the tariff on imported cars is 15%. Starting from July 1, 2018, the import tariffs on complete vehicles and auto parts were reduced. The tariff rates for 135 tariff lines on auto parts with a 25% rate and 4 tariff lines with a 20% rate were lowered to 15%. The tariff rates for 79 tariff lines on auto parts with rates of 8%, 10%, 15%, 20%, and 25% were reduced to 6%. The reduction in import car tariffs has the following benefits: 1. Promote the development of the domestic automotive industry: After several stages of development, the industry has reached a level where it can further integrate and compete internationally. It is time to relax protective mechanisms, encourage competition between domestic and foreign automakers, and accelerate structural adjustments and transformations, thereby promoting better development of China's automotive industry under more open conditions. 2. Promote supply-side structural reform in the automotive industry: With this tariff reduction, competition in the domestic automotive market will undoubtedly intensify, significantly increasing pressure on domestic automakers. Many independent brands will accelerate their transformation and upgrading, also driving supply-side structural reform in the automotive industry. 3. Stimulate consumption: With the deepening of reform and opening-up, reducing import car tariffs helps expand imports and domestic demand while meeting the needs of domestic consumption upgrades. The reduction in the terminal prices of imported cars will inevitably pose a certain threat to joint venture and independent brands in the same segment. Therefore, lowering prices and improving product quality will be the path for joint venture and independent automakers, which is clearly more beneficial to consumers.

Why does the electric vehicle charger keep showing a red light and not fully charge?

If the electric vehicle charger keeps showing a red light and fails to fully charge, it could be due to a damaged charger or a problem with the battery. Here are some relevant explanations about electric vehicles: 1. Charging Principle: After the light turns green, continue charging for 2-3 hours. The principle of charging is to charge frequently with shallow discharges. Charge when the battery level drops to around 50%, but avoid charging too frequently as it will shorten the battery's lifespan. If the vehicle is not used for a long time, charge it periodically (once a month). For batteries that are frequently shallow-discharged, perform a deep discharge every 3 months or so, which means discharging completely before recharging. This helps activate the inactive substances deep inside the battery. Discharging completely means until the controller's low-voltage protection is triggered. 2. Precautions: Generally, after 8-10 months of use, new batteries should be inspected and maintained. Chargers that come with well-known brand vehicles are usually pre-screened and do not require testing. However, for non-matching chargers purchased separately from the market, it is essential to test the aforementioned three parameters. There is a type of thyristor charger without a power frequency transformer that directly rectifies the mains power to charge the battery. The current can reach 30A, and the voltage is adjustable from 12V to 80V. Never touch the battery before the mains power is completely disconnected. Customers using such chargers for freight tricycles should pay special attention to safety.
