Please check engine system refers to the need to inspect the engine to determine if there is a fault in the emission system or an issue with the oxygen sensor. When the engine experiences a malfunction, these faults generate a series of codes. After the ECU reads the fault codes, they will appear as indicator lights on the dashboard, requiring the owner to visit a 4S shop to read the fault codes and identify the specific cause. The engine is a machine capable of converting other forms of energy into mechanical energy, first developed in the UK. It can be used as a power generation device or refer to the entire machine including the power unit. Its types include internal combustion engines, external combustion engines, electric motors, etc.

Why Can't My New Energy Vehicle Charge?

Reasons why a new energy vehicle cannot charge are as follows: 1. The internal fuse of the battery is blown. 2. Poor contact. Poor contact can occur in many aspects, such as between the fuse tube and the fuse holder, between the plug and the socket, or between the charger and the power source. Any of these can affect the normal charging of the electric vehicle, resulting in the battery not charging or not charging fully. 3. The battery has reached the end of its lifespan. The normal lifespan of a battery is about 5 years, but frequent incorrect charging methods can lead to premature battery failure. Solutions for a new energy vehicle that cannot charge: Regardless of the reason, if the vehicle cannot charge, it is advisable to contact a 4S store as soon as possible and seek professional help. Do not attempt to repair it yourself, as this can easily cause secondary damage.

What is the difference between 91v and 94v on tires?

The difference between 91v and 94v on tires: 91v indicates a load index of 615kg; 94v indicates a load index of 670kg. The functions of tires are as follows: 1. Prevent severe vibrations and premature damage to vehicle components, adapt to the high-speed performance of the vehicle and reduce driving noise, ensuring driving safety, handling stability, comfort, and energy efficiency. 2. Support the entire weight of the vehicle, bear the load of the car, and transmit forces and moments in other directions. 3. Transmit traction and braking torque, ensure good adhesion between the wheels and the road surface to improve the vehicle's power, braking, and passability; work together with the vehicle suspension to mitigate impacts during driving and dampen resulting vibrations.

Must the dowry car be brand new?

The dowry car does not necessarily have to be brand new. Here are some relevant considerations regarding the use of new cars: Avoid overloading: Carrying too much weight during the break-in period can damage the mechanical components of a new car. Since the power transmission parts of a new car have not yet fully broken in, aggressive acceleration can cause irreversible damage. Therefore, it is essential to follow the principle of "slow and steady" during the break-in period. Speed limits for new cars: For domestic cars, the speed limit is generally between 40-70 km/h, while for imported cars, it is around 100 km/h. When the throttle is fully open, the speed should not exceed 80% of the maximum speed. The recommended engine speed during the break-in period is between 2,000-4,000 rpm.

Can a Car Still Under Installment Loan Be Used as Collateral for Another Loan?

A car under an installment loan cannot be used as collateral for another loan until the existing loan is fully repaid. Relevant information: Specific reasons: Because the ownership of any mortgaged vehicle belongs to the lending institution, and the car owner only has the right to use it. Since the installment vehicle has not yet been fully repaid, the ownership does not yet belong to the individual, so it cannot be mortgaged. Legal basis: Article 33 of the "Guaranty Law": The term 'mortgage' as used in this Law refers to the act where the debtor or a third party, without transferring the possession of the property listed in Article 34 of this Law, uses such property as security for the claim. If the debtor fails to perform the obligation, the creditor shall have the right to be paid with priority from the proceeds of the discounted price, auction, or sale of the said property in accordance with the provisions of this Law. The debtor or the third party specified in the preceding paragraph is the mortgagor, the creditor is the mortgagee, and the property provided as security is the mortgaged property.

How Many Degrees to Turn the Steering Wheel When Pulling Over?

When pulling over, the steering wheel should be turned by 45 degrees. Below are the steering wheel angles for pulling over: Steering wheel angles: For lane changing when pulling over, the steering wheel should be turned 3-10 degrees, which means rotating it 2-5 centimeters. Avoid sudden steering movements, especially at high speeds, as this can easily cause the vehicle to roll. After entering the permitted parking lane on the right, you can slowly turn the steering wheel 45 degrees to align. Alignment tips: The key to alignment is ensuring the front hood of the car overlaps with the right-side road boundary line, at which point the right side of the car should be about 30 cm from the road boundary line. Then, make slight adjustments to maintain this overlap for a certain distance, and the car body will straighten out. Finally, press the brake to stop, turn off all lights, shift to neutral, engage the handbrake, and turn off the engine before leaving.
