What are the most obvious symptoms of cylinder scoring in a diesel engine?

Cylinder scoring is characterized by noticeable jerking of the vehicle, accompanied by significant abnormal noises from the engine, reduced RPM, and a clear drop in power output. Traditionally, when cylinder scoring occurs, the cylinder needs to be bored, meaning the cylinder is enlarged to remove the worn-out areas. After boring, oversized pistons must be used, as standard pistons can no longer be employed. Below is relevant information: 1. Cylinder Scoring: Cylinder scoring refers to severe surface damage caused by the relative motion between the piston and the cylinder. The primary cause is often the localized destruction of the lubricating oil film in the moving parts, leading to scratches, scoring, or seizure. Although the extent of damage may vary, these conditions are collectively referred to as cylinder scoring. 2. Causes: Insufficient clearance between the piston and cylinder; poor lubrication between the piston and cylinder, or the use of inappropriate engine oil; piston ring breakage or seizure on the piston, or failure of the piston pin retaining ring; misalignment of the piston and piston rings, causing excessive pressure on the cylinder wall.

Will the insurance company compensate for a car catching fire spontaneously?

Purchasing spontaneous combustion insurance will result in compensation. A vehicle catching fire spontaneously falls within the coverage of spontaneous combustion insurance. Only if the car owner has insured against spontaneous combustion will the insurance company compensate according to the terms agreed in the contract. However, if the insured vehicle catches fire due to modifications or failure to undergo annual inspections on time, the insurance company will also refuse to compensate. Coverage of car spontaneous combustion insurance: Coverage one: Losses to the insured vehicle caused by fires due to issues with the vehicle's electrical system, wiring, fuel system, gas supply system, cargo itself, or friction during vehicle operation. Coverage two: Necessary and reasonable rescue expenses incurred by the insured to reduce the loss of the insured vehicle during the insurance incident. Coverage three: The victim bears the burden of proof for spontaneous combustion caused by the vehicle's own issues. If the victim can prove that the product had a defect, the use of the defective product caused damage, and there is a legal causal relationship between the defective product and the damage, then product liability is established. The producer must then provide evidence for statutory exemptions. If they cannot prove the existence of exemption circumstances, they shall bear the liability for damages.

What to Do If a Vehicle with Only Compulsory Traffic Insurance Is Involved in an Accident?

If a vehicle with only compulsory traffic insurance is involved in an accident, the owner can negotiate with the responsible party through traffic police mediation; the owner can exercise the right to claim compensation independently or the insurance company can exercise the right of subrogation. Mediation and Negotiation: Once a traffic accident occurs, according to Article 89 of the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China," if both parties jointly request mediation, the traffic police can mediate on the spot regarding the dispute over damages. Therefore, at this time, the traffic police need to coordinate, first determining the liability for the accident, and then resolving the compensation issue. Exercising the Right to Claim Compensation Independently: According to Article 18 of the "Tort Liability Law," the owner can list the responsible party and the insurance company that underwrites the compulsory traffic insurance as co-defendants and file a lawsuit in court. If the other party only has compulsory traffic insurance but it is insufficient to cover the losses, legal action can be taken directly to pursue legal liability. This method is also very effective, although it may take a longer time.

Can You Still Drive with a Fuel Tank Leak?

A fuel tank leak means you should not drive. Oil leakage is a common issue during vehicle operation. Once leakage occurs, it leads to excessive waste of lubricating oil and fuel, resulting in more severe power loss. In serious cases, it can cause inadequate engine lubrication and cooling. When a vehicle is found to be leaking oil, immediate repair or inspection may not always be possible. In most cases, people continue driving. However, continuing to drive poses significant safety hazards and reduces the vehicle's lifespan and durability. Upon detecting a leak, immediate inspection is necessary, along with regular maintenance and checks. If a fuel tank leak is not repaired promptly, exposure to open flames—even a cigarette butt that isn't fully extinguished—can cause the vehicle to catch fire or explode. The original engine contains oil, so even with a leak, it may still operate for a certain distance. The exact distance depends on the oil fault warning light; when the light comes on, the engine must be stopped immediately. Oil leaks leave stains, and the severity can be judged by these stains. Vehicles typically contain several fluids, including gasoline, engine oil, brake fluid, gear oil, and power steering fluid. Gasoline and engine oil differ in color and smell, so it's important to learn how to distinguish between them.

What is the reason for the sudden increase in idle speed when stepping on the brake?

The reason for the increase in engine speed when stepping on the brake may be due to a faulty ignition coil, resulting in insufficient ignition energy; a dirty throttle, leading to abnormal air-fuel mixture; a vacuum booster system leak, causing insufficient system vacuum; or a transmission or engine electronic control system malfunction, resulting in unstable operation when braking. Below is relevant information: 1. Engine speed: The higher the engine speed, the more work is done per unit of time, so the power is greater. However, higher speeds accelerate the entire cycle, causing fuel to be expelled before it has enough time to fully combust. Therefore, fuel consumption increases exponentially. Thus, higher speed is not always better. The speed should mainly be determined by the vehicle's speed and gear. Maintaining around 3000 RPM is sufficient. Additionally, avoiding low-gear high-speed and high-gear low-speed driving is essential, as both are harmful to the engine. 2. Emergency braking: When performing emergency braking, press the brake pedal firmly. Most vehicles without ABS systems are not recommended to brake with full force at once; instead, brake in two separate steps to prevent wheel lock-up, which can lead to skidding and steering lock. However, ABS systems are now standard in vehicles, so in emergency situations, it is crucial to press the brake pedal with full force.

What is Tire Pressure Monitoring?

Tire pressure monitoring is the real-time automatic monitoring of tire pressure during vehicle operation, with alerts for tire leaks and low pressure to ensure driving safety. There are three commonly used methods of tire pressure monitoring: Direct Tire Pressure Monitoring: Direct tire pressure monitoring devices use pressure sensors installed in each tire to directly measure tire pressure. The pressure information is transmitted wirelessly from inside the tire to a central receiver module, which then displays the pressure data for each tire. The system automatically alerts when tire pressure is too low or there is a leak. Indirect Tire Pressure Monitoring: When the pressure in a tire decreases, the vehicle's weight causes the rolling radius of that wheel to become smaller, resulting in a faster rotation speed compared to other wheels. By comparing the differences in rotation speeds between tires, the system monitors tire pressure. Indirect tire alert systems essentially rely on calculating the rolling radius of tires to monitor pressure. Introduction to Tire Intelligent Monitoring System (TPMS): This system combines the advantages of the two aforementioned systems. It is equipped with direct sensors in two diagonally opposite tires and includes a 4-wheel indirect system. Compared to using only a direct system, this hybrid system reduces costs and overcomes the limitation of indirect systems in detecting simultaneous low pressure in multiple tires. However, it still cannot provide real-time data on the actual pressure in all four tires as effectively as a direct system.
