How to Handle Speeding by 20%?

Driving a motor vehicle on the highway at a speed exceeding the limit by less than 20% will result in a deduction of 3 points and a fine; speeding by more than 20% but less than 50% will result in a deduction of 6 points and a fine. Here is some relevant information about speeding: 1. Article 42 of the "Road Traffic Safety Law of the People's Republic of China" stipulates that motor vehicles driving on the road shall not exceed the maximum speed indicated by speed limit signs. On road sections without speed limit signs, a safe speed shall be maintained. 2. Speeding refers to the situation where the driver operates the vehicle at a speed exceeding the legal or regulatory limits. A turbine overspeed accident is a serious and malignant accident caused by faults in the speed regulation and protection system or inherent defects of the turbine itself. Speeding by less than 10% will not be penalized for the time being, while speeding by more than 10% but less than 20% will result in a fine and a deduction of 3 points.

Why does the speedometer fluctuate up and down?

The speedometer fluctuates up and down due to a malfunction in the vehicle speed sensor. A faulty vehicle speed sensor can also cause unstable engine idle, momentary stalling or engine shutdown when starting or decelerating to stop while driving, as well as reduced engine acceleration performance. Here is more detailed information: The speedometer consists of two gauges: the speedometer and the odometer. The odometer is a digital instrument that calculates rotation through the engagement of components on the calculator's gear. It primarily obtains mileage signals from the speed sensor and can retain data even without power. The vehicle speed sensor is a device used to detect the speed of electronically controlled vehicles. The control computer uses this input signal to regulate engine idle speed, torque converter lock-up in automatic transmissions, automatic transmission gear shifting, engine cooling fan operation, cruise control, and other functions. The output signal from the vehicle speed sensor can be a magnetoelectric AC signal, a Hall-effect digital signal, or a photoelectric digital signal. The vehicle speed sensor is typically installed inside the drive axle housing or transmission case. The sensor signal wires are usually housed in shielded jackets to eliminate electromagnetic and radio frequency interference caused by high-voltage ignition wires, car phones, or other electronic devices.

Is it normal for the car's idle speed to drop from 800 rpm to 600 rpm?

If the car's idle speed used to be 800 rpm and has now dropped to 600 rpm, this situation is not normal. Common causes for this phenomenon include a dirty or clogged intake system, engine misfire or poor working conditions, and a clogged three-way catalytic converter in the exhaust system. Dirty or clogged intake system: During vehicle use, components such as the throttle body, air filter, and idle air control valve can easily accumulate dirt and become clogged. Once clogged, the engine's idle speed will become lower and unstable, making it harder to start and more prone to stalling. The solution is to inspect the intake system for clogs every one and a half to two years and clean it promptly if necessary. Engine misfire or poor working conditions: Check the aging level of the ignition coils and spark plugs, inspect whether the fuel injectors are clogged or damaged, and check if the control unit wiring is damaged. Faults in the ignition system can lead to sluggish acceleration and engine shaking at idle. The solution is to inspect and repair the ignition system, replacing components if needed. Clogged three-way catalytic converter: When the engine operates under poor conditions for an extended period, it can cause the three-way catalytic converter to clog. Symptoms include low idle speed and a muffled engine sound. The solution is to replace or clean the three-way catalytic converter.

What are the consequences of changing tires from 65 to 60?

Introduction to the consequences of changing tires from 65 to 60: First, driving the vehicle on the road is considered illegal because it involves unauthorized modification, and the vehicle will not pass the normal annual inspection. During vehicle use, it has a significant impact on fuel consumption, increasing the vehicle's fuel usage. The driving stability of the vehicle will be affected, and comfort will also be somewhat compromised. It is not recommended to make such a change. Here is some related information about tires: 1. Car tires can be categorized into more than 10 types based on their purpose, including passenger car tires, heavy-duty vehicle tires, and off-road vehicle tires. Structurally, they can be divided into radial tires, conventional bias tires, full-size spare tires, and non-full-size spare tires. 2. As one of the most important components of a car, tires support the vehicle's weight and enable it to drive on various road conditions. Different types of tires have distinct characteristics based on their intended use. Passenger car tires offer higher comfort, while off-road tires provide stronger road passability. When selecting a car, it is essential to consider the road conditions it will be driven on to avoid choosing the wrong type, which could affect tire performance.
