How to Remove the Rearview Mirror Rain Guard Film?

The methods to remove the rearview mirror rain guard film are: 1. Use the warm air setting of a heater to blow warm air on the film for a while before peeling it off; 2. Locate the edge of the rain guard film at the corner of the rearview mirror and slowly peel it off. The methods to apply the rearview mirror rain guard film are: 1. Clean the outer surface of the vehicle's side mirror thoroughly; 2. Apply the rain guard film to the middle area of the outer rearview mirror. The rearview mirror rain guard film is made of nano-material, and its functions are: 1. Raindrops will not adhere to the lens to form water beads, allowing the driver to clearly see the traffic behind; 2. It buffers light, providing a soft reflection and reducing interference with visibility.

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.
