Research on automotive fragrance/air purification: With surging installations, automotive olfactory interaction is being linked with more scenarios

As users require higher quality of personalized, intelligent and scenario-based car life, the healthy air in cars receives ever more attention. At present, automotive air conditioning systems mainly use air conditioner, air filters (filter elements, PM2.5 filter devices, AQS, physical adsorption, etc.), air purification systems (negative ion/plasma generator, ultraviolet generator, photocatalyst technology, etc.), and fragrance systems to bring pleasant fragrance to cockpits, remove formaldehyde and odor, purify harmful gas particles with negative ions, and kill and inhibit bacteria.

Chinese standards for monitoring and managing in-car air quality include the national standard GB/T 27630-2011 'Guideline for Air Quality Assessment of Passenger Car', the association standard 'Passenger Cars - In-car Air Quality Measurement and Odor Evaluation Methods', the industrial standard QC/T 998-2023 'Cabin Air Filter for Automobiles', the association standard 'Testing Specifications for Automotive Fragrance Capsules', the association standard 'Technical Specifications for Automotive Fragrance Systems" and the association standard "Key Chemical Substances Controlled by REACH in the Automotive Industry Part 2: Testing Specifications'.

In the aspect of air quality health certification, besides the CN95 healthy cockpit certification of China Automotive Technology & Research Center (CATARC) & CAQC (by the particle filtration efficiency index of automotive air conditioner filters, the certified products are divided into five grades: CN60, CN70, CN80, CN90 and CN95, of which CN95 is the highest grade, that is, the filtration efficiency of 0.3m non-oily particles exceeds 95%), there is also 'China Automotive Health Index' introduced by China Automotive Engineering Research Institute Co., Ltd. (CAERI), covering five evaluation dimensions, namely, volatile organic compounds (VOC), vehicle odor intensity (VOI), electromagnetic radiation (EMR), particulate matter (PM) and vehicle allergy risk (VAR).

The installations of automotive air conditioning devices have increased, especially automotive fragrance having seen exponential growth.

At present, automotive air conditioning devices mainly include fragrance systems, air purifiers, PM2.5 filter devices and negative ion systems.

From 2021 to May 2024, the installations of automotive air purifiers and fragrance systems rose rapidly. In 2023, 821,000 cars were equipped with fragrance systems as standard; from January to May 2024, fragrance systems as a standard configuration were installed in 489,192 cars, a year-on-year spike of 122%. It is expected that over 1.1 million cars will carry such systems in 2024.

Meanwhile, the installations of air purifiers made steady growth. It increased by 14.8% year on year in 2022 and 22.4% year on year in 2023 as standard. From January to May 2024, 2.451 million vehicles were equipped with air purifiers as standard, a year-on-year increase of 7.8%. It is expected that air purifiers will be installed in over 7 million vehicles in 2024. From January to May 2024, 6.3336 million vehicles were installed with PM2.5 filters, a year-on-year increase of 12.1%; 1.0256 million vehicles carried negative ion systems, a year-on-year decrease of 5.7%.

Air purification technologies such as photocatalyst and ultraviolet ray are applied to more models.

On mainstream models, air purification systems are mainly used for disinfection and sterilization, for example, plasma purification, photocatalyst purification and ultraviolet sterilization. At present, air purification systems are often matched with air filters to build a complete automotive air purification management system. An automotive air purifier is an air purification device specifically used to purify PM2.5, toxic and harmful gases (formaldehyde, benzene, TVOC, etc.), odor, bacteria, viruses and other in-car pollutants.

For in-car air purification, ever more OEMs are trying to apply such technologies as ultraviolet disinfection and photocatalyst to improve the in-car air health index, in addition to negative ions/plasma. For example, AITO M9 uses UVC photocatalyst disinfection technology, and the high-configuration model of GAC Toyota Camry is equipped with photocatalyst air purifiers and Panasonic nanoeT X, a nano negative ion air moisturizing purification system.

Photocatalyst, represented by nanometer titanium dioxide (TiO2), is a collective name for semiconductor materials that does not change under the irradiation of light but can promote chemical reactions and has catalytic function. The biggest feature of photocatalyst is that it strongly absorbs ultraviolet rays in light. After absorbing ultraviolet rays, the molecules of photocatalyst move violently and become active, but its substance remains unchanged. When odorous substances (formaldehyde, acetic acid, ammonia, etc.) in the air pass through the photocatalyst net, they collide with the active photocatalyst, absorb some energy, and become active as well. The molecules move violently and unsteadily, a series of chemical reactions (which are called photodissociation reactions) occur, and the odorous substances are transformed into odorless substances.

For example, AITO M9 uses a UVC photocatalyst disinfection system combined with air conditioning to not only efficiently filter out tiny particles such as PM2.5 and dust, but also actively eliminate viruses and bacteria in the air conditioning duct and internal air. According to the testing report issued by the authoritative organization "National Center of Quality Inspection and Testing on Air Purification Products", the photocatalyst air sterilizer assembled into AITO M9 can effectively kill the common influenza virus H1N1, with the removal rate higher than 99.99% within 15 minutes. The killing rate of Staphylococcus albus in 15 minutes goes beyond 99.9%. The extinction rate of natural bacteria in the air surpasses 94% within 30 minutes.

In addition, the principle of ultraviolet disinfection is to destroy the molecular structure of DNA or RNA in microbial cells by using ultraviolet rays with appropriate wavelength, resulting in the death of growing cells and/or regenerative cells, thus accomplishing disinfection. The automotive ultraviolet sterilization systems on market generally adopt the UVC wavelength band (200~275 nm).

Fragrance systems are heading in the direction of multimodal control.

The fragrance system releases the fragrance to the whole vehicle through the air conditioning system. The automotive intelligent fragrance system can control the switch according to the settings, and adjust the fragrance concentration, mode and working time interval through various intelligent methods such as WeChat applet, voice control or smart control panel. In general, an automotive intelligent fragrance system is composed of a fragrance container, IVI display, audio control system, fragrance controller and fragrance actuator.

Automotive olfactory interaction is linked with more scenarios.

In the future, in-vehicle air conditioning is not only about air purification, odor removal and pleasant fragrance, but also about matching the users' application scenario through various scenario modes and intelligently adapting to meet the individual needs of users. In-vehicle olfactory interaction will enable scenario interaction, releasing different scents according to scenarios, for example, releasing appropriate fragrance (e.g., AION LX Plus' Chinese fragrance) in scenarios with babies or elderly people, and sending out the corresponding scent (e.g., the earthy smell when it is sunny after rain) according to the ambient atmosphere and music style.
