Is There 98-Octane Gasoline?

Gas stations all have 98-octane gasoline. Differences in gasoline grades: The octane rating varies. 98-octane gasoline is a mixture of 98% isooctane and 2% n-heptane, while 95-octane gasoline consists of 95% isooctane and 5% n-heptane. Performance of different gasoline grades: 98-octane gasoline offers higher anti-knock performance and power output, whereas 95-octane gasoline has average anti-knock combustion capability. Gasoline appears as a transparent, flammable liquid, refined from various petroleum-derived components such as straight-run gasoline, catalytic cracking gasoline, and catalytic reforming gasoline. After refining, it is blended with high-octane components and primarily used as fuel for spark-ignition internal combustion engines in automobiles.

What is the Chinese equivalent of Euro IV?

Euro IV emission standard is equivalent to China's National IV emission standard. Emission standards: National 3 and National 4 standards are based on Euro 3 and Euro 4 vehicle emission standards. Compared with National 2, National 3 further reduces the limits of pollutant emissions. The exhaust pollutant emission limits of China's Phase 3 standard are 30% lower than those of Phase 2 standard, while China's Phase 4 standard will further reduce them by 60%. Euro IV: The Euro IV standard refers to the Euro IV emission standard, which was implemented at the end of 2005 and is an important standard for vehicle exhaust emissions, currently implemented in most countries. This standard requires that diesel cars emit no more than 250 milligrams of nitrogen oxides per kilometer; vans and SUVs emit no more than 390 milligrams of nitrogen oxides per kilometer.

Is there a big difference between year-end and year-beginning vehicle registration?

Mainly the difference lies in the vehicle age and used car price. Different vehicle age: The calculation of a vehicle's age is based on the registration date of the new car. Therefore, there will be a one-year difference in vehicle age between year-end and year-beginning registrations. Different price: Year-end registration is more expensive than year-beginning registration. The longer the vehicle age, the lower the depreciation rate. Therefore, when purchasing a car, try to choose the registration date at the beginning of the year, which will provide some advantages when disposing of the used car later. License plate: It serves as the numbering and information registration for vehicles. Its main function is to identify the vehicle's region through the license plate, and also to trace the vehicle's owner and registration information based on the plate.

What is the principle of an oil pressure sensor?

The principle of an oil pressure sensor is: pressure directly acts on the diaphragm of the sensor, causing the diaphragm to produce a micro-displacement proportional to the medium pressure. This changes the resistance of the sensor, and electronic circuits detect this change and convert it into a standard signal output corresponding to the pressure. Relevant information about oil pressure sensors is as follows: 1. Suitable for automatic weighing measurement, overload protection, and workload management of loaders (including forklifts). It can measure coal or coke, non-ferrous ores, earthwork, granite or marble, sand, crushed stone bricks, industrial and domestic waste, excavation materials, and construction additives. 2. According to the operational characteristics of loaders, the signal acquisition part generally includes three types: weighing sensors, pressure (oil pressure) sensors, and pressure (oil pressure) transmitters. It is important to emphasize that the sensor should have good performance in terms of overload protection, vibration resistance, insulation, and anti-interference.
