What is the function of vehicle sensors?

In automotive electronic control systems, sensors are widely used in various electronic control systems of the engine, chassis, and body. Automotive sensors are responsible for collecting and transmitting information. The electronic control unit processes this information and then issues commands to actuators to implement electronic control. They can promptly identify changes in the external environment and within the system itself, and then control the system's operation based on the changing information. Sensors can be classified into two major categories based on energy relationships: active and passive. Here is an introduction to sensors: 1. Signals: Sensors primarily output two types of signals: analog and digital. Digital signals can be directly input into the electronic control unit, while analog signals need to be converted into digital signals via an A/D converter before being input. The electronic control unit continuously monitors the signals from various sensors. If an abnormal input signal is detected, the erroneous signal is stored in memory. During fault diagnosis and repair, technicians can read fault information using specialized diagnostic tools or manual methods, and then proceed with repairs based on the fault code information. 2. Electronic Control Unit: For the electronic control unit to effectively manage the system's operation, certain conditions must be met. The accuracy, responsiveness, reliability, durability, and output voltage signals of the sensors play a crucial role in ensuring the stability of the system's control.

How Often Should the Engine Intake Manifold Be Cleaned?

Engine intake system should be cleaned every six months or every 20,000 kilometers. Here is an introduction to the relevant knowledge about the engine intake manifold: 1. Function: The inlet and passage for the air required by an air-breathing jet engine. The intake manifold not only supplies the engine with a certain flow of air, but the intake flow field must also ensure the normal operation of the compressor and combustion chamber. 2. Classification: Modern automobile intake systems are mainly variable intake systems. Variable intake systems are mainly divided into four types: VVT (Variable Valve Timing), CVVT (Continuous Variable Valve Timing), VVT-i (Electronic Variable Timing), and i-VTEC (Electronic Variable Valve Lift).

How to Pay Motorcycle Purchase Tax Online?

Motorcycle purchase tax can be paid online through the electronic tax bureau website of the local state tax administration in your province. After registration, select "Self-declaration by Unit Taxpayer", or "Declaration by Vehicle Dealership" and "Natural Person Declaration". After filling in the information on the page, wait for the tax bureau's system to complete verification before proceeding with payment. Payment notes: 1. Ensure accurate information is filled in: On the declaration page, enter the vehicle identification number, invoice code, and invoice number correctly. When entering the vehicle registration page, select the correct license issuing authority code and your province/city. 2. Taxable amount calculation: Vehicle purchase tax payable = taxable price × 10%. This means the purchase tax rate for small-scale vehicles is 10%.

Does Valve Ticking Need to Be Repaired?

If the valve ticking is only slight, it indicates that the valve clearance is small and no repair is needed; if the valve ticking is loud, it is necessary to check the valve clearance and whether the valve is severely worn to avoid engine damage leading to an overhaul. Symptoms of valve ticking include: difficulty starting the vehicle, lack of power when overtaking, decreased engine power, and carbon deposits on the valve and valve seat cone surfaces. The repair method for valve ticking: the lapping method can be used to clean the carbon deposits on the valve before lapping, and after achieving a certain roundness and cylindricity, install and measure whether the valve clearance is within the normal range.

Does the car count as scrapped if the airbags deploy?

When the airbags deploy, they are considered scrapped, but the car itself is not. Here is some relevant information about airbags: 1. Introduction: Airbags in cars are installed in front of the driver and passengers. When the car collides with an obstacle ahead, they can instantly inflate and expand rapidly due to the enormous inertial force, thereby providing a cushioning effect. Additionally, airbags are equipped with safety valves that automatically release some gas if over-inflation occurs or the internal pressure exceeds a certain level, preventing passengers from being crushed or injured. 2. Function: The primary function of airbags is to prevent injuries caused by collisions between passengers and the interior components of the car during a crash. They typically serve as supplementary safety devices to seat belts.
