Car change news? On July 30th, 20021China's research report on the odor inside the car was released in Beijing, which included the release of 20021China's research report on the odor inside the car and the study on the health impact of volatile organic pollutants inside the car.
As we all know, in-car health, as an important indicator of automobile quality, has attracted wide attention from all walks of life in recent years. The air quality in the car directly affects the physical and mental health of drivers and passengers. With the enhancement of social health awareness, people put forward more requirements for the cockpit environment. In-car health has gradually covered air quality (including odor and VOCs emissions), particulate matter filtration, noise, prohibited substances, electromagnetic radiation, microorganisms, anti-allergy and other fields, in which the odor inside the car is the focus of consumers' attention on the models.
In order to help enterprises improve the technical level of odor control in the car and promote the green and healthy development of the automobile industry, it is particularly important to publish the research results of the odor report in the first half of 200212002 to the public, including consumer complaints about the odor in the car, source analysis and comprehensive analysis results of key models.
According to statistics, the number of complaints about the smell in cars in China is increasing year by year. In order to clarify consumers' demands for improving the smell inside the car, deeply analyze the present situation of odor performance in the industry, and guide enterprises to develop automobile products with more comfortable smell, China Consumer Products Quality and Safety Promotion Association (hereinafter referred to as "China Consumers Association") and China Automobile Data Co., Ltd. (hereinafter referred to as "China Automobile Data") jointly initiated the compilation of "China Automobile Smell Research Report", and conducted research from the perspective of consumers' odor.
At present, there are still several difficulties in controlling the odor in the car. Due to seasonal factors, supply cycle, storage conditions and other reasons, the odor performance of mass-produced vehicles in some enterprises is worse than R&D or control targets, and there is a lack of effective communication mechanism between automobile R&D and customers. Secondly, the key substances causing odor are not included in the control scope, and the existing evaluation system of car companies is not perfect. In addition, the complexity of the problem of odor in the car, including many harmful substances, large differences in material composition, odor control before detection.
According to the research report, through market research and data analysis, in-depth odor investigation and analysis, odor substance analysis and odor comprehensive analysis are carried out on vehicles with high consumer concern. The research content includes several aspects. Engaged in consumer odor survey can help car companies understand the real demand of consumers for vehicle odor, design and develop low-odor environmentally-friendly cars from the source, and conduct full-spectrum VOCs detection by raising interest rates on odor sources. Lock the key odor substances. For vehicles with high complaint rate, the subjective and objective coupling evaluation of odor is conducted by random sampling, and the odor performance of vehicles is comprehensively analyzed from the aspects of objective odor intensity, odor concentration, odor type and odor pleasure.
In the part of market research, according to the platform research results approved by the State Administration of Market Supervision, as of the end of June 20021year, there were 27,728 complaints about the smell inside cars in China. In terms of automobile brand complaints, independent, joint venture and imported brands are all involved; In terms of complaining about the owner's information, male owners account for more than 90%, which shows that male owners pay more attention to the problem of odor inside the car; Judging from the areas where car owners complain, they are mainly distributed in Guangdong, Jiangsu and Shandong provinces, accounting for more than 30% of the national complaints, indicating that people in these areas are highly sensitive to the odor inside the car.
In the part of data analysis, the odor data of 10 vehicles were collected in the first half of 200210, and the vehicle odor results and typical vehicle performance were analyzed in the past two years.
10 models are elantra, civic, Passat, roewe RX5 MAX, mg EZS, song Pro, outlander, BMW, Tesla Model Y and Mercedes-benz GLC. There are 7 vehicles at room temperature (MG EZS, Civic, Roewe RX5 MAX, Passat, Elantra, etc. ) The number of high-risk substances is better than the average. The objective intensity of odor is better than that of general 5 cars (Outlander, MG EZS, Model Y, Mercedes-Benz GLC, Passat), the odor concentration is better than that of general 5 cars (MG EZS, Outlander, Passat, Roewe RX5 MAX, Civic), and the odor pleasure is better than that of general 9 cars. The quantity of high-risk substances is better than that of the general five vehicles (Model Y, Roewe RX5 MAX). The objective odor intensity of five vehicles (Model Y, MG EZS, Outlander, Mercedes-Benz GLC and Passat) is better than the average value 1 of six vehicles (MG EZS, Passat, Civic, Model Y, Roewe RX5 MAX and Outlander).
From the above research results, it can be seen that the odor inside the car is an important factor affecting consumers' car purchase, and auto companies should continue to pay attention to it; The compliance of the eight VOCs in the industry is not optimistic, and auto companies should continue to strengthen the air quality control inside the car to ensure that the products meet the standards; There is still room for improvement in the performance level of odor in the industry, and individual models are extremely disgusted by consumers, such as paint smell, which is easy to cause odor complaints and should be controlled.
In addition, odor data of 30 models will be collected in the second half of the year, including SAIC- Volkswagen Tiguan L, FAW-Volkswagen Sagitar/Tan Yue/Golf, SAIC-GM Yinglang, Great Wall Haval H7, Geely Job/Geometry A, Dongfeng Nissan Qi Jun/Hacker, Changan UNI-T, < A class = "hidden" href = "/ Dongfeng-27.
