Filing is required. Below is the relevant information about installing a car spoiler: 1. Reason: Installing a car spoiler is considered an alteration of the car's appearance, and the owner must file for registration with the vehicle management office in advance. If the car spoiler is installed privately without filing, the public security traffic management department will detain the vehicle, confiscate the illegal device, order restoration to the original state, and impose a fine according to the law. After the modification is completed, the vehicle license must be re-photographed and replaced to ensure that the photo on the license matches the modified vehicle, ensuring that the car can pass annual inspections and routine safety checks after modification. The requirement for installing a spoiler is that after installation, the spoiler should not exceed the overall dimensions of the vehicle. 2. Main function of a car spoiler: The main function of a car spoiler is to provide sufficient downforce, reduce the lift at the rear of the vehicle, and ensure that the car remains firmly on the road, maintaining sufficient stability during driving.

Regarding the matter of adding a spoiler to a car, I personally believe that it indeed requires registration in China. According to traffic regulations, modifications to the vehicle's body structure must be registered with the vehicle management office, otherwise, it is considered illegal modification. I have helped a friend with this process, and it's quite simple: bring the vehicle registration certificate, ID card, and the spoiler's instruction manual to the vehicle management office for declaration. They will arrange an inspection to check if the spoiler's dimensions comply with regulations and if the installation is secure, then proceed with registration and stamping. If not registered, you may be fined 500-2000 yuan and receive penalty points from traffic police, and the vehicle will fail the annual inspection. Worse, in case of an accident, insurance claims might be hindered, or there's a significant risk of the spoiler detaching during high-speed driving. Therefore, I recommend not being lazy—legal modifications are more worry-free and ensure the vehicle's safety performance meets standards. After registration, you can enjoy your modifications with peace of mind. Before modifying, it's best to check the specific procedures with the local vehicle management office.

What does ECM mean on a car?

Automobile ECM refers to the Engine Control Module, which has the function of continuously monitoring and controlling the normal operation of the engine. Below is a detailed introduction to automotive ECM: Importance of ECM: The automotive engine control module is one of the most important automotive electronics. It can provide the engine with the optimal air-fuel ratio mixture and the best ignition timing according to different engine conditions, ensuring the engine always operates in the best state. The engine's performance, power, fuel economy, and emissions are optimized. Working principle of ECM: During operation, the ECM collects information about various working states of the engine through various sensors (including temperature sensors, pressure sensors, rotation sensors, flow sensors, position sensors, oxygen sensors, knock sensors, etc.), and sends this information to the ECU via transmission lines.

What is the purpose of recycling automotive three-way catalytic converters?

The reason for recycling three-way catalytic converters is that they contain many rare metals. These metals have the potential for recycling and reuse, so to avoid waste, there are specialized individuals who recycle three-way catalytic converters. Appearance: The three-way catalytic converter looks like a metal can from the outside, but inside it has a 'substrate' for purifying exhaust gases. This honeycomb-shaped ceramic substrate is coated with a precious metal slurry, primarily composed of platinum, rhodium, and palladium. Function: The precious metals act as catalysts, reducing hydrocarbons (HC) and carbon monoxide (CO) in the exhaust into water and CO2, while breaking down nitrogen oxides (NOx) into nitrogen and oxygen. This is the exhaust purification function of the three-way catalytic converter.

What is the normal engine RPM at 120 km/h?

At 120 km/h, most vehicles' engine RPM ranges between 2500-3000. This specifically relates to engine displacement and the manufacturer's power tuning. The relationship between RPM and vehicle speed, along with influencing factors, are as follows: Relationship between RPM and vehicle speed: Generally, the higher the engine RPM, the higher the vehicle speed, showing a proportional relationship. The specific calculation formula is: Vehicle speed = RPM × Transmission ratio × Tire circumference. Influencing factors: Besides RPM affecting vehicle speed, the transmission ratio and tire circumference also influence it. Additionally, friction and air resistance are significant factors. It's noteworthy that once the engine reaches its rated power, increasing RPM won't raise the vehicle speed further, as the onboard computer will cut off fuel supply.
