What is a car air filter - residential entrance - pipe
The tubes beside the car air filter mainly have the following functions:
Crankcase ventilation system pipeline
It is used to reintroduce the exhaust gas in the engine crankcase into the intake manifold for combustion, balance the crankcase pressure, and prevent the direct emission of exhaust gas from causing pollution. This system is equipped with an oil-gas separator that can separate exhaust gas from oil vapor, preventing oil from entering the combustion chamber.
Waste gas recirculation pipe
Connect the air filter to the exhaust device, allowing the unburned exhaust gas to re-enter the air filter for filtration and then enter the engine for secondary combustion, thereby improving fuel utilization and reducing emission pollution.
Throttle air duct
In some models, this pipe mixes the fresh air after the air filter element with the crankcase exhaust gas, diluting the exhaust gas concentration, preventing the formation of carbon deposits and maintaining the engine's sealing performance.
These pipes work together to ensure the efficient operation of the engine and need to be inspected and maintained regularly to prevent blockage or leakage problems.
Based on your inquiry "Car air filter - Residential entrance - Pipe Function", I understand that you want to know about the functions of car air filters, residential entrance air filtration equipment and related pipes. Now I will introduce it to you in three parts.
The function of a car air filter
The main function of automotive air filters (including engine intake filters and air conditioning filters) is to filter the air entering the engine or the cabin to ensure its cleanliness.
For the engine intake system, it can filter out harmful impurities such as dust and sand particles in the air, prevent these particles from entering the cylinder and causing early wear (such as the "cylinder pulling" phenomenon), and at the same time ensure that a sufficient amount of clean air enters to support the complete combustion of fuel, thereby protecting the engine and extending its life .
For the air conditioning system, it can adsorb fine particles (such as dust, dust) and odors (such as gas smell) entering from the outside, prevent these pollutants from moldy and breeding bacteria in the system, avoid generating odors and causing passenger allergies (such as tearing, itching and other symptoms), thereby keeping the air inside the vehicle fresh .
The function of air filtration equipment at residential entrances
The air filtration equipment at the entrance of a residence (such as a fresh air system or a haze removal fresh air machine) is mainly used to improve indoor air quality. It effectively removes pollutants such as PM2.5, dust and pollen by filtering the air entering from the outside, while introducing fresh air to achieve ventilation and air exchange, thereby ensuring the health and comfort of the living environment.
The function of pipes
In an air filtration system, pipes (such as intake pipes, supply pipes, etc.) play a crucial role in guiding and transporting air. In a car, the intake pipe is responsible for introducing the filtered air into the engine cylinder, and designs such as the resonant cavity can also reduce the intake noise ; In addition, some of the pipes also participate in the crankcase ventilation system to reintroduce the exhaust gas into the combustion . In a residential fresh air system, the ducts are responsible for delivering the filtered clean air to all areas of the room or expelling the stale air outdoors, ensuring the effectiveness of air circulation.
