What is the corresponding gasoline octane rating for compression ratio?

Compression ratio can indeed serve as one of the criteria for determining the appropriate fuel octane rating for an engine. Engines with a compression ratio below 8 can use 90-octane gasoline, those below 9 can use 93-octane gasoline, and engines with a compression ratio above 9 should use 97-octane gasoline. Impact of compression ratio: The compression ratio affects the gasoline octane rating required by an engine because the air-fuel mixture generates heat during compression. Higher cylinder pressure leads to increased heat and higher temperatures. Reason why compression ratio affects fuel selection: Lower-octane gasoline has a lower ignition point than higher-octane gasoline and is more easily ignited. Therefore, engines with low compression ratios use lower-octane gasoline, while high-compression engines require higher-octane gasoline.

What to Do If an Accident Occurs with an Un-transferred Used Car Insurance?

The new Insurance Law (2009) stipulates that after the transfer of vehicle ownership, the new owner inherits the rights and obligations of the original insured. This means that as long as the vehicle has been transferred before the accident occurs, regardless of whether the insurance policy has been transferred, the actual insured is the current owner at the time of the accident. You can file an insurance claim with the insurance company. (Refer to the Insurance Law for details) More relevant information is as follows: Note 1: Insurance companies can only refuse to pay claims if the transfer results in a significant increase in the risk level of the subject (vehicle), such as changing from non-commercial to commercial use. (Refer to the insurance terms for details) Note 2: Currently, the China Insurance Regulatory Commission is addressing the issue of difficulties in auto insurance claims. Professional insurance company claims personnel will determine whether to pay based on the aforementioned circumstances, rather than directly refusing payment on the grounds that the policy has not been transferred. This reason is invalid, not recognized by the Insurance Regulatory Commission, and will not be upheld in court.

Will I be charged extra tax for buying another car if I already own one?

Owning one car and buying another will not incur additional taxes; the fees remain the same as for the first car. Below is relevant information about car taxes: 1. Car taxes: Include purchase tax, vehicle and vessel usage tax, comprehensive tax paid when purchasing imported vehicles, among other major components. 2. Vehicle purchase tax calculation formula: Vehicle purchase tax payable = taxable price × 10%. 3. Vehicle and vessel tax: Levied annually per vehicle. It is divided into 7 tiers based on the vehicle's engine displacement, ranging from 1.0 liters (inclusive) and below to over 4.0 liters.

What is the Principle of Modifying a Heavy Car Steering Gear to Light?

Working principles are similar in that they both utilize a hydraulic pump (driven by the engine belt) to provide oil pressure that pushes the piston, thereby generating auxiliary force to move the steering linkage and assist in wheel steering. The difference lies in the driving method of the oil pressure pump. Mechanical hydraulic power steering directly drives the hydraulic pump via the engine belt, while electro-hydraulic power steering employs an electric pump driven by electricity. Below is relevant information: 1. Reasons for a heavy steering wheel: Like other automotive fluids, power steering fluid needs to be replaced. Another scenario is low tire pressure, which can also make the steering wheel feel heavier, and in severe cases, may even lead to a tire blowout due to insufficient pressure. 2. Precautions: While driving, avoid holding the steering wheel at full lock for extended periods, especially during turns and reversing. Prolonged full lock can cause the power steering pump's oil pressure to drop too low, potentially damaging the pump and resulting in a heavy steering wheel condition.

What adhesive should be used for a detached car roof lining?

HY-T160 adhesive can be used. 1. Edge detachment of the roof lining: Edge detachment of the roof lining may be caused by aging of the fabric sponge, leading to the edges coming loose. This issue is relatively easy to fix. You can use a specialized roof lining adhesive by applying it along the detached edge, waiting a few minutes for the adhesive to dry and harden, and then pressing it back into place. 2. Bulging or sagging in the middle of the roof lining: If there is bulging or sagging in the middle of the car roof lining, you can opt for clip repairs. Choose clips that match the color of the lining and fasten them back. The downside is that this method may not look very aesthetically pleasing. 3. Large-scale detachment of the roof lining: If the roof lining has detached over a large area, the only solution is to remove and replace it entirely.
