Excessive nitric oxide in cars is caused by: clogged or failed three-way catalytic converters, leading to reduced performance. Solutions for excessive nitric oxide in cars: 1. Consistently use high-quality gasoline to ensure its purity; 2. Regularly clean the fuel injectors and three-way catalytic converter to ensure accurate fuel injection; 3. Replace the oxygen sensor. Cars produce nitric oxide because fuel combustion in vehicles occurs through spark plug ignition with air intake, which contains nitrogen and oxygen. During spark plug discharge and ignition, fuel combustion also generates significant heat, promoting a chemical reaction between nitrogen and oxygen.

How many types of gasoline are available in China?

In China, gasoline models include China IV with 90#, 93#, and 97#, and China V with 89#, 92#, 95#, and 98#. Below is relevant information about gasoline models: 1. Gasoline grades: The gasoline grade refers to the ratio of the actual gasoline's anti-knock performance to that of standard gasoline. The higher the grade, the stronger the anti-knock performance. Standard gasoline is composed of isooctane and n-heptane. Higher grades are not necessarily better; the appropriate gasoline grade should be selected based on the engine's compression ratio. In December 2011, Beijing proposed changing the gasoline grades from "90#, 93#, 97#" to "89#, 92#, 95#" and stipulated that the sulfur content should not exceed 0.001%. 2. Gasoline composition: Gasoline appears as a transparent, flammable liquid with a distillation range of 30°C to 220°C. Its main components are C5–C12 aliphatic hydrocarbons and cycloalkanes, along with a certain amount of aromatic hydrocarbons. Gasoline has a high octane number (anti-knock combustion performance) and is classified into grades such as 90#, 93#, 95#, and 97# based on the octane number. Gasoline is produced by refining various gasoline components obtained from petroleum refining, such as straight-run gasoline, catalytic cracking gasoline, and catalytic reforming gasoline, and blending them with high-octane components. It is primarily used as fuel for spark-ignition internal combustion engines in automobiles.

What is the fuel tank capacity of the BYD F0?

The BYD F0 2015 1.0L Yueku model has a fuel tank capacity of 30L. It is equipped with a 1.0L naturally aspirated engine and a 5-speed manual transmission (MT). The drivetrain is front-engine, front-wheel drive. The front suspension is a MacPherson strut type, while the rear suspension is a torsion beam with trailing arm. In the same vehicle class, the BYD F0 2015 1.0L XuanKu model also has a 30L fuel tank capacity, while the Changhe Beidouxing X5 2020 1.4L Comfort model has a 42L fuel tank capacity. During actual refueling, the amount of fuel may exceed the marked capacity. This is because the fuel tank capacity specified by the manufacturer is measured from the bottom of the tank to the safe fill level. There is additional space from the safe fill level to the tank opening, which is designed to allow for fuel expansion due to temperature increases without causing overflow. If fuel is filled up to the tank opening during refueling, the actual amount of fuel added may exceed the marked capacity. To check the remaining fuel level, drivers can observe the fuel gauge on the right side of the instrument panel, which is marked with 'E' (Empty) and 'F' (Full). When the needle is close to 'E,' it indicates low fuel, while nearing 'F' means the tank is nearly full.

What does variable speed limit on highways mean?

Variable speed limit enforcement is an intelligent speed monitoring system designed for foggy traffic conditions. Here is relevant information: 1. Function: Used on roads and highways to promptly alert drivers about their driving speed. The speed limit value can be displayed through the monitoring center based on actual road conditions. Variable speed limits use LED illuminated signs to inform drivers of the current speed limit, which isn't fixed but changes according to actual driving conditions. 2. Components: The equipment for variable speed limit enforcement typically includes high-definition cameras, license plate recognition systems, 3-megapixel high-definition capture devices, narrow-beam radar, LED lights, protective housings, electronic display screens, and consists of control centers with front-end and back-end systems.
