What does oil ash content mean?

Oil ash content refers to the inorganic matter obtained by calcining the residue of oil after carbonization under specified conditions, expressed as a percentage by weight. The ash content mainly consists of naphthenate compounds present in the oil. Below is a detailed introduction about automotive engine oil: Overview: Engine oil, also known as engine lubricant, is referred to as Engine-oil in English, with a density of approximately 0.91×10³ (kg/m³). It serves to lubricate and reduce friction in the engine, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption. Composition: Engine oil consists of two parts: base oil and additives. The base oil is the main component of lubricating oil, determining its basic properties. Additives can compensate for and improve the deficiencies in the performance of the base oil, imparting certain new properties, making them an important part of lubricating oil.

How Long Can You Drive After the Engine Oil Expires?

How long you can drive after the engine oil expires depends on the type of oil used in the vehicle. Generally, engine oil is divided into three types: full synthetic, semi-synthetic, and mineral oil. Typically, full synthetic oil should be replaced every 10,000 kilometers or once a year. Semi-synthetic oil is usually replaced every 7,500 kilometers or every 7-8 months. Mineral oil is generally replaced every 5,000 kilometers or every 6 months. Below is a detailed introduction to engine oil: Overview: The condition of the engine oil not only directly affects the engine's performance but also impacts its lifespan. The working environment of engine oil is extremely harsh, as impurities from gasoline combustion contaminate the oil, causing it to oxidize and degrade over time. Other: Engine oil, also known as engine lubricant, serves multiple functions, including lubrication and friction reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, and shock absorption.

How to Determine a Right-Turn Red Light?

When the red light is on while making a right turn, you must not continue driving. Stay where you are, and as long as you are not captured in three photos, you will not be recorded for running a red light. Below is some information about traffic violation handling: 1. Time Frame: The vehicle owner needs to go to the local traffic police station within 15 days of receiving the penalty SMS after the violation. If you fail to handle it within 15 days, a 3% late fee will be charged daily, but the late fee will not exceed double the original fine amount. Handle it early to avoid unnecessary penalties. 2. Confirmation Method: The fastest and most effective way to know if you have run a red light is to check for red light violations at the vehicle management office or traffic police station. You need to bring important documents such as your driver's license, vehicle license, and ID card—all three are indispensable. It is also advisable to prepare some cash (running a red light usually incurs a fine of 200 yuan, and other violations may result in additional penalties). This way, even if a violation is found, you can immediately proceed with the necessary formalities.

Can motorcycles be driven in urban areas?

In general, motorcycles can be driven in urban areas, but a driving license is required. Motorcycles are a special type of vehicle. Below is a detailed introduction about vehicle types: Overview: Vehicle type refers to a form of vehicle, distinguished by common characteristics, intended use, and functions. For example, sedans, trucks, buses, trailers, and incomplete vehicles are all separate types. Others: Heavy-duty vehicles have a length greater than or equal to 6m and a total mass greater than or equal to 12,000kg. Medium-duty vehicles have a length greater than or equal to 6m and a total mass greater than or equal to 4,500kg but less than 12,000kg. Light-duty vehicles have a length less than 6m and a total mass less than 4,500kg. Mini vehicles have a length less than or equal to 3.5m and a load capacity less than or equal to 1,800kg.

What Causes the Engine Fault Light to Illuminate After Wading Through Water?

If the engine fault light illuminates after wading through water, it indicates an issue with the vehicle's engine. This is usually caused by the engine belt slipping due to water ingress, and the problem can typically be resolved by thoroughly drying the water from the engine belt. Reasons for the engine fault light to illuminate include: 1. Fuel quality issues: Poor or substandard fuel quality. If the engine fault light comes on immediately after refueling, it is often due to filling up with low-quality fuel at an unregulated gas station. While this situation does not affect the vehicle's operation, it can cause damage to the engine. 2. Damaged water temperature sensor: When the engine is cold, the water temperature sensor sends information to the ECU to enrich the air-fuel mixture, ensuring stable engine operation. If the sensor fails to indicate the cold engine state, the air-fuel mixture will become too lean, leading to unstable engine performance. Conversely, if the sensor sends a cold engine signal when the engine is warm, the air-fuel mixture will become too rich, also causing abnormal engine operation. 3. Carbon buildup in the engine and spark plugs: Over time, carbon deposits accumulate in the engine, leading to engine damage, difficulty starting, poor acceleration, excessive engine noise, and other issues. The accumulated heat can cause erratic ignition, resulting in engine knocking. In such cases, the engine fault light will illuminate.

Can C1 License Holders Drive All Blue Plate Trucks?

C1 license holders cannot drive all blue plate trucks. A C1 driver's license allows driving small passenger vehicles with 9 seats or fewer (including 9 seats) and all blue plate trucks (with a vehicle length under 6 meters).

Driver's License: The full name is motor vehicle driver's license, also known as a "driving license," which is a certificate required by law for motor vehicle drivers. Driving a motor vehicle requires certain driving skills, and those lacking such skills may cause traffic accidents if they drive recklessly. Generally, individuals cannot drive on the road without a license. However, for those who have acquired safe driving skills, the document that permits them to drive on the road is the "driver's license." 2. Types of Vehicles C1 License Holders Can Drive: According to regulations, a C1 license allows driving small vehicles, including small/micro passenger vehicles, light/micro cargo vehicles, light/small/micro special-purpose vehicles, and the types of vehicles permitted by C2, C3, and C4 licenses.
