How many horsepower is 1kw of engine power equal to?

Engine power of 1kw is approximately equal to 1.36 horsepower. This conversion is artificially defined, taking a value very close to the imperial horsepower. It is stipulated that 1 metric horsepower is the work done to move 75 kilogram-force meters in 1 second, which equals 75 kilogram-force meters per second or 735 watts. The engine's power is not equal to the vehicle's power. In mechanical transmission, there are intermediate power losses. Additionally, designs that thicken and reinforce the vehicle body for safety reasons can also lead to engine power losses. Therefore, vehicles equipped with small-displacement engines are not necessarily slower or inferior in performance compared to those with high-power engines.

What is the working principle of a differential?

The working principle of a differential is essentially a rolling diagram of a wheel. Its function is to allow the left and right wheels to rotate at different speeds when the car is turning or driving on uneven road surfaces, ensuring that both driving wheels perform pure rolling motion. The differential is designed to adjust the speed difference between the left and right wheels. A standard differential consists of components such as planetary gears, the planetary carrier (differential housing), and axle shafts. The engine's power is transmitted through the driveshaft into the differential, directly driving the planetary carrier, which in turn drives the left and right axle shafts via the planetary gears, thereby powering the left and right wheels respectively. The design requirements of the differential must satisfy the condition that the speed of the left axle shaft plus the speed of the right axle shaft equals the speed of the planetary carrier. When the car is moving straight, the speeds of the left wheel, right wheel, and planetary carrier are equal, maintaining a balanced state.

How long do electric vehicle batteries generally last?

Electric vehicle batteries generally last about 3 years. Improper usage can shorten the battery's lifespan. As the number of charge and discharge cycles increases, the performance of the electric vehicle battery will decline, and the battery will need to be replaced periodically. A battery consists of a positive electrode, negative electrode, and electrolyte. The chemical reactions inside the battery are reversible—the direction of the reaction reverses during charging and discharging. The shallower the depth of discharge each time the battery is used, the longer the battery's lifespan. Therefore, regardless of the capacity of the battery pack, it's advisable to develop the good habit of charging immediately after use. Frequent charging keeps the battery in a saturated state as much as possible. Avoid carrying passengers when possible, switch to pushing when encountering slopes, and try to minimize frequent braking and starting during operation.

Why is traffic violation code 10871 not handled on the spot?

Violation code 10871 refers to unauthorized modification of a motor vehicle's appearance, with a penalty of 0 demerit points and a fine of 500 yuan. According to regulations, the fine should be issued with a unified receipt from the provincial, autonomous region, or municipal finance department; if such a receipt is not provided, the party involved has the right to refuse payment. Generally, traffic police do not carry receipts with them, so this violation is not handled on the spot. Relevant regulations on vehicle modifications are as follows: The style of the wheel rims can be changed, but the specifications must match those on the motor vehicle registration certificate. The height-to-width ratio of a modified roof rack must be controlled within 300mm, and the width of side steps cannot exceed 5cm beyond the vehicle body's side profile. The vehicle's color can be changed through painting or wrapping, but within ten days of the change, the vehicle must be taken to the vehicle management office to update the vehicle information. It is important to note that colors similar to those used on emergency vehicles such as police cars or fire trucks are prohibited. Illegal vehicle modifications can pose safety hazards and increase the risk of accidents. Therefore, modifications must be legal and promptly registered. There are four common ways to check for motor vehicle violations: Visit the office halls of traffic departments in various districts and counties to use touch-screen terminals for inquiries. Log in to the public service websites of local public security traffic management bureaus, locate the vehicle violation query section, enter the license plate number and engine number, and click to query. Call the inquiry hotline (area code + 114). Use the "Traffic Management 12123" app to check. Violations related to unauthorized modification of a vehicle's appearance can be handled through the "Traffic Management 12123" app as follows: Step 1: Log in to the "Traffic Management 12123" app, navigate to [Business Center] → [Violation Handling], and enter the violation handling process. Step 2: Select the vehicle with the violation to view the list of unprocessed violations. Click on a specific violation to see detailed information. Step 3: After selecting the violation to process, click [Handle and Pay], read the terms carefully, and click [Read and Agree] to proceed to the confirmation and payment method selection page. Step 4: Click [Confirm] to proceed to the payment page and complete the payment.

Can I change the license plate number without transferring ownership?

You cannot change the license plate number without transferring ownership. If the vehicle owner's residence moves out of or into the jurisdiction of the vehicle management office, they should apply for a change of registration at the registration office, which requires replacing the vehicle license plate. Generally, once a vehicle is licensed, it is very difficult to change the license plate. If a change is absolutely necessary, it can only be done through vehicle ownership transfer. There are two forms of transfer: one is transferring it as a used car—selling the vehicle as a used car first and then purchasing a new one with a new license plate; the other is transferring ownership between spouses—changing the vehicle registration to the spouse's name and then purchasing a new vehicle and selecting a new license plate.

Do I Need to Contact the 4S Store After Paying Off My Car Loan?

After paying off your car loan, it is not necessary to contact the 4S store. It depends on where the loan was applied for, and you need to find the institution that issued the loan. Once you locate the lending institution, obtain a loan clearance certificate. Take this certificate to the vehicle management office to complete the vehicle lien release registration. Only after the lien is released does the purchased vehicle fully belong to the borrower. The process for releasing the mortgage contract is as follows: 1. Inquire about the repayment status to confirm that all payments have been made; 2. Bring your ID card, vehicle registration certificate, bank repayment details, etc., to collect the vehicle registration certificate; 3. Go to the local municipal vehicle management office to complete the vehicle lien release procedures; 4. Change the primary beneficiary of the car insurance.
