Can a Car Be Sold After Being Mortgaged?

After a car is mortgaged, it can be bought and sold, but the ownership cannot be transferred. Chinese law clearly stipulates that mortgaged cars can be traded, but the transfer of ownership is not allowed. The reason a mortgaged car cannot have its ownership transferred is that the car has already been mortgaged, and the property rights temporarily do not belong to the owner. Therefore, the owner does not have the right to transfer the ownership of a car that temporarily does not belong to them to someone else. Thus, purchasing a mortgaged car does not grant ownership rights, only the right to use. Only after the mortgage is fully repaid and the mortgage is lifted can the transfer of ownership be processed. The term 'mortgage' refers to a situation where a debtor or a third party does not transfer the possession of the property listed herein, but uses the property as collateral for a debt. If the debtor fails to fulfill the debt, the creditor has the right to prioritize repayment by either converting the property into money or through auction or sale of the property, as stipulated by law. The debtor or third party mentioned in the preceding paragraph is the mortgagor, the creditor is the mortgagee, the property provided as collateral is the mortgaged property, along with interest, penalty fees, compensation for damages, and the costs of enforcing the mortgage. If the mortgage contract stipulates otherwise, those terms shall prevail.

What Causes the Car Dashboard Lights to Illuminate?

There are several reasons why the car dashboard lights may illuminate, including ECU CAN bus failure and poor contact at the ECU CAN interface. Excessive dirt and carbon deposits can obstruct airflow, preventing accurate control of normal air intake, leading to unstable gas content and poor engine performance. Low fuel pressure combined with poor constant pressure performance results in inadequate system atomization, making the car difficult to start. Dashboard indicator lights can generally be categorized into three types. Daily Indicators: These are the most common lights encountered while driving, such as turn signal indicators, light indicators, seat belt indicators, cruise control indicators, and parking indicators. They serve to indicate the operational status of various vehicle functions. Warning Indicators: Examples include the fuel level indicator and windshield washer fluid level indicator. These lights alert the driver to promptly replenish the corresponding fluids to resolve the issue. Fault Indicators: These include the engine (exhaust system) warning light, oil system warning light, battery and charging system warning light, among others. Fault indicators rarely illuminate under normal circumstances, but when they do, they indicate that the vehicle has encountered a malfunction or abnormality. Minor issues may affect driving safety, while severe ones could potentially damage the vehicle. Immediate inspection and repair are necessary, or contact the vehicle's brand 4S store for assistance.

What is the normal range for a car's coolant temperature gauge?

Generally, the coolant temperature of a regular household car during normal operation is around 95 degrees Celsius, while some high-performance cars or vehicles with higher thermal efficiency may operate at around 110 degrees Celsius. Cars with higher operating temperatures include BMW models, whose engines can even exceed 110 degrees Celsius under normal working conditions. The vehicle's cooling system is not solely designed for heat dissipation but to help the engine maintain an optimal operating temperature range. Many drivers pay close attention to coolant temperature, and some car dashboards are equipped with a coolant temperature gauge. However, besides coolant temperature, oil temperature is equally important. Excessively high oil temperature can cause the oil to thin, leading to oil film rupture, which results in engine wear. Conversely, if the oil temperature is too low, the oil becomes too viscous, preventing it from adequately lubricating the necessary components. Therefore, oil temperature is also crucial. When driving, it's advisable to avoid prolonged high-speed operation, as this can cause the oil film to rupture, leading to abnormal engine wear. Engine oil also plays a role in heat dissipation. If the engine is low on oil, it can easily overheat, potentially causing cylinder scoring.

Can a car's mileage be adjusted?

Car mileage can be adjusted. There are two types of car odometers. For mechanical odometers, the mileage adjustment method involves removing the instrument panel and manually turning the mechanical gears to change the mileage. For digital display odometers, the adjustment method involves modifying the mileage data stored in the microcontroller within the instrument panel that displays the mileage on the LCD screen. Car mileage is calculated based on the number of rotations of the tires (front wheels), which is computed by sensors and the car's computer and then displayed on the odometer. The total mileage of a car refers to the total distance the car has traveled, and the number displayed on the odometer in the car's dashboard represents the car's mileage. Locate the odometer sensor plug on the car's clutch housing (the position varies by car, sometimes found on the transmission or driveshaft), and gently pull it out by hand. Then insert the output clip of the mileage adjuster into the signal socket of the pulled-out sensor plug. Adjust the small knob on the mileage adjuster to set the car's speed to the desired level.

What is the principle of car gear shifting?

The principle of car gear shifting is achieved by changing the transmission gears. There are gears of different speeds on the tire rotation shaft. When the engine speed remains unchanged, if gears of different speeds are engaged with the engine, the circumferential speed obtained by the larger gear will be less than that of the smaller gear. In low gear, the gear is larger, and the engine drives a larger radius with a smaller radius, allowing the car to obtain greater driving force. In high gear, the engine drives a smaller radius with a faster circumferential speed, resulting in less driving force. The gearbox is essentially a gearbox containing many gears. The driving gear (connected to the engine via the main clutch) receives power from the engine to drive the driven gear (connected to the wheels via the main reducer and drive shaft), thereby driving the rotation of the wheels. Each gear has a pair of driving and driven gears. Engaging a specific gear means that particular pair of gears is combined to transmit power. As the gearbox shifts to higher gears, the transmission ratio continuously decreases. By fifth gear, it is generally less than 1, meaning the output speed of the gearbox is higher than the engine speed. The output speed of the gearbox is directly proportional to the vehicle speed. Therefore, lower gears provide greater power but lower speed (under a certain engine speed), while higher gears offer less power but higher speed.

What Causes the Engine Light to Illuminate in a Car?

There are several reasons why a car's engine warning light may illuminate, including sensor malfunctions, maintenance issues, and fuel/oil quality problems. Sensor malfunctions: Sensors such as coolant temperature, crankshaft position, air flow, intake air temperature, and oxygen sensors can trigger the engine light when damaged, experiencing poor contact, or signal interruption. In such cases, the vehicle's ECU cannot accurately obtain engine data. Maintenance issues: Poor engine maintenance is the most common cause of engine warning light activation. Vehicles have specific maintenance schedules, and failure to adhere to these schedules combined with poor driving habits can increase the engine's operational burden, eventually triggering the warning light. Fuel/oil quality problems: This refers to both fuel and engine oil quality. Automobiles typically require specific fuel grades, while engine oils are categorized as semi-synthetic or fully synthetic. Manufacturers usually recommend appropriate fuel grades and oil types. Failure to follow these recommendations over time can lead to engine wear.
