Jetta valve noise is caused by: 1. Excessive wear of the valve guide inner hole; 2. Insufficient oil pressure in the cylinder head; 3. Excessive clearance between the hydraulic lifter and the cylinder head. Taking the 2020 Jetta as an example, its body dimensions are: length 4419mm, width 1841mm, height 1616mm, wheelbase 2630mm, fuel tank capacity 51l, and trunk capacity 482l. The 2020 Jetta features a front McPherson independent suspension and a rear multi-link independent suspension. It is equipped with a 1.4L inline 4-cylinder turbocharged engine, delivering a maximum horsepower of 150ps, maximum power of 110kw, and maximum torque of 250nm, paired with a 6-speed automatic transmission.

Where is the USB port in the Volkswagen Santana?

The USB port in the Volkswagen Santana is located below the air conditioning controls on the center console. The USB interface is a type of vehicle transmission cable known for its fast data transfer, ease of use, support for hot-swapping, flexible connectivity, and independent power supply. It is typically a universal port for connecting USB devices such as flash drives and MP3 players. Below is more information about car USB ports: 1. Car USB ports are primarily designed for transmitting audio data. The current output of car USB ports can vary, with some providing 5V/2.1A and others 5V/0.5A. Many smartphones require an input current of 5V/1A, so a 5V/2.1A car USB port can safely provide 1A to a phone and 2A to a tablet. 2. A car charger is a device that converts the 12V from the cigarette lighter to 5V USB power, allowing it to charge phones and tablets. There is also another type that converts the 12V DC from the cigarette lighter to 220V AC, which can be used with low-power appliances when connected via a power strip.

How to Deal with Fogging Inside the Car During Summer Rain

Solutions for fogging inside the car during summer rain are as follows: 1. Preventive methods like spraying anti-fog agents: Spray a small amount of defogger on the car windows (inner side) and wipe it clean to remove dirt and stains from the glass. While polishing the glass, it forms a thin transparent protective film that effectively prevents moisture from condensing on the glass and forming a fog layer. 2. Air conditioning cooling method: Use the air conditioning's dehumidification function to reduce air humidity and remove fog. 3. Air conditioning warm air method: During summer rain, you can also blow warm air onto the glass to quickly raise the temperature of the front glass, reducing the temperature difference between the inner and outer surfaces of the window. This can promptly prevent excessive fogging on the windshield. However, it should be noted that the rear and side windows heat up more slowly, so it takes longer to completely remove all the fog.

What are the three braking methods of motor vehicles?

There are mainly three braking methods in automobiles, which represent service braking, parking braking, and engine braking respectively. They are the braking methods used in different scenarios. Detailed introduction to the three braking methods of motor vehicles: 1. Service braking: commonly known as 'foot brake'. It is the braking method used during normal driving, mainly by converting the mechanical force of the brake pedal into hydraulic pressure, which is then transmitted to the brake and applied to the four tires of the vehicle to achieve the braking effect. 2. Parking braking: also commonly known as 'hand brake'. It is the braking method used when the vehicle is parked, preventing the vehicle from sliding when stationary. The main working principle involves connecting a steel wire cable to the brake shoe to apply braking, generally acting on the rear wheels of the vehicle. 3. Engine braking: compared to service braking and parking braking, engine braking is somewhat more special. It mainly utilizes the compression resistance, exhaust resistance, and internal friction generated during engine operation to brake the drive wheels. It is generally used in special environments, such as muddy roads and icy conditions.

Will there be penalties for not displaying a temporary license plate on a motorcycle?

There will be no penalties if you have a temporary license plate and it is within the validity period. Details are as follows: 1. Do not let it expire: The use of temporary license plates for new vehicles must not exceed 15 days. The owner should promptly apply to the vehicle management authority for a formal license plate. After expiration, penalties may include temporary vehicle seizure, a fine of 200 yuan, and a deduction of 12 points. 2. Temporary license plates: These are paper motor vehicle license plates that allow temporary road use of motor vehicles, also known as temporary driving license plates. They are temporary vehicle driving certificates issued by the public security vehicle management department for newly purchased vehicles before formal registration. 3. Four types of plates: The validity period of temporary license plates generally does not exceed 30 days. There are four types: temporary license plates for administrative jurisdictions, temporary license plates for cross-administrative jurisdictions, temporary license plates for testing purposes, and temporary license plates for special-type motor vehicles.

What is the load capacity of a car?

Generally, the load capacity of a family car ranges from 375 to 500 kg. The national standard is 375 kg, meaning the production load capacity of a car cannot be lower than 375 kg. Detailed introduction is as follows: 1. There are two types of vehicle load standards: One is the vehicle load standard based on traffic regulations, where two-axle vehicles should not exceed 20 tons, front four rear four vehicles 24 tons, and front four rear eight vehicles 34 tons. Exceeding these limits results in fines calculated per thousand. The other is the vehicle load standard in the eyes of traffic police, based on the vehicle's registration certificate, which is the tonnage specified on the factory certificate. Exceeding this limit results in fines calculated per hundred. 2. For the maximum passenger load of a five-seat car (rough estimate, the specific value should refer to the manual): Generally, each person is calculated at 75 kg, and the total luggage weight at 100 kg, so 5*75 + 100 = 475 kg.

What Are the Causes of Insufficient Oil Pressure?

The causes of insufficient oil pressure include the following points: 1. Insufficient oil quantity in the oil pan. When the oil quantity is insufficient, the oil pump's pumping capacity decreases, and it may even suck in air. The oil should be replenished according to the specified amount. If the insufficient oil is caused by oil burning or leakage, the issues of oil burning or leakage should also be addressed. 2. The oil quality does not meet the requirements. Different engine models require different grades of oil, and even the same engine model may use different brands of oil in different seasons. Using the wrong oil often leads to issues such as excessively thin oil viscosity and insufficient lubrication. Always use oil as specified. 3. Fuel or water mixing into the oil. If fuel mixes into the oil, it will dilute the oil; if water mixes into the oil, it will cause the oil to emulsify and deteriorate. Both scenarios reduce the oil's lubrication effectiveness. The oil must be replaced, and the causes of fuel or water mixing into the oil should be identified and resolved. 4. Excessive oil temperature. When the cooling system has severe scaling, poor heat dissipation, or prolonged overload operation leading to high engine temperatures, the oil may become thin. If the clearance between the cylinder liner and piston is too large, high-temperature gas from the cylinder can enter the crankcase, raising the oil temperature and thinning it, making it easier to leak from the friction pair's clearance. 5. Clogged oil filter screen or air leakage in the oil intake line. When the oil strainer screen is clogged, the oil pump cannot draw in enough oil. If the oil intake pipe has cracks, the gasket is uneven or not tightened, or the joint surface between the pump body and the engine block is uneven or the gasket is damaged (as in single-cylinder diesel engines), the oil pump may suck in air. These issues can all lead to insufficient oil pressure.
