Can the original owner deregister a used car if the ownership is not transferred?

If the buyer of a used car does not complete the ownership transfer, the seller cannot apply for vehicle deregistration. Below is relevant information about the car purchase contract: 1. Introduction: The car purchase contract is a formal sales agreement signed between the buyer and the dealer, serving as a basis to protect the rights and interests of both parties. According to the "Motor Vehicle Registration Regulations", the requirements for deregistration are as follows: Article 27 states that for motor vehicles that have reached the national mandatory scrapping standards, the owner must submit an application form when selling the vehicle to a recycling company. School buses, large passenger vehicles, trucks, and other commercial vehicles must be dismantled under the supervision of the vehicle management office. 2. Signing: During the transaction of a used vehicle, it is mandatory to sign the purchase contract supervised by the industrial and commercial department, known as the sales contract, which is made in duplicate with each party holding one copy.

Can Automotive Engine Oil Be Used in Motorcycles?

Automotive engine oil should not be used in motorcycles. The reasons why automotive oil cannot be used in motorcycles are as follows: 1. In cars, the engine and transmission are separate, whereas in motorcycles, the transmission mechanism is integrated with the engine. Using automotive oil in motorcycles can cause clutch slippage. 2. The load on a motorcycle engine is much higher than that on a car engine. Car engines typically operate at a few thousand RPM, while motorcycle engines run at much higher RPMs, with some scooters even exceeding 3,000 RPM at startup. 3. The intensity of a motorcycle engine is usually 3-4 times higher than that of a car engine. Due to their lightweight design, motorcycles often operate at the RPMs corresponding to maximum power or torque output, resulting in higher engine temperatures and greater wear.

Should You Turn Off the Air Conditioning Before Turning Off the Car?

Turn off the air conditioning before turning off the car. If you turn off the car first and then turn on the air conditioning, the engine will start with the load of the air conditioning the next time the vehicle is started, which can damage the engine due to the high load. Additional information: 1. Principle of car air conditioning: The working principle of car air conditioning involves the refrigeration system, which consists of components such as the compressor, condenser, liquid storage dryer, expansion valve, evaporator, and blower. These parts are connected by copper pipes (or aluminum pipes) and high-pressure rubber hoses to form a closed system. 2. The compression process of car air conditioning: The compressor sucks in the low-temperature and low-pressure refrigerant gas at the outlet of the evaporator and compresses it into a high-temperature and high-pressure gas, which is then discharged from the compressor.

What Causes Excessive Short-Term Fuel Trim Values?

Excessive short-term fuel trim values are caused by a lean air-fuel mixture. Here is additional information: 1. Lean mixture: When the air-fuel mixture is too lean, the oxygen sensor's output voltage decreases, causing the short-term fuel trim to increase. This means the fuel injection pulse width will lengthen. An increase in short-term fuel trim indicates that the values read on the diagnostic tool will be greater than 1. 2. Difference between short-term and long-term trim: Short-term fuel trim is a real-time correction control of the fuel injection quantity based on the oxygen sensor's feedback regarding the richness or leanness of the mixture in previous working cycles. On the other hand, changes in the long-term fuel trim coefficient are qualitative changes formed by the ECU based on quantitative changes from the continuous correct feedback of short-term fuel trim. This is the key difference.
