However, do you know that vehicle air pollution is more terrible than indoor air pollution? Yes, because the space inside the car is smaller, the ventilation condition is worse, and the concentration of pollutants produced is higher, so it is more harmful to human body.
There are four major culprits in automobile air pollution, including formaldehyde, benzene series and ammonia. , mainly from plastic parts, carpets, linoleum, seats and other decorative adhesives in automobiles. These pollutants are harmful to the skin, breathing, blood and cardiovascular system, ranging from dizziness, chest tightness and respiratory inflammation to human nerve paralysis and even cancer in severe cases.
The Air Monitoring Center of China Interior Decoration Association has tested 200 vehicles, and found that if we refer to the indoor air quality standards, nearly 90% of the vehicles have the problem of excessive formaldehyde or benzene content in the air, and most vehicles have formaldehyde exceeding the standard by more than five or six times, among which the air quality in new cars is the worst. A foreign research test shows that the volatilization time of harmful gas concentration in a new car can last for more than 6 months after it leaves the factory. In the meantime, the car is like a moving gas chamber.
And some car owners will think of using air freshener or perfume to cover up the odor inside the car, but this is a temporary solution. First of all, many pollutants are colorless and tasteless and can't be felt by the sense of smell at all, but the cover-up of odor can't eliminate pollutants; Even many fresheners themselves contain volatile pollutants, which may cause more serious secondary air pollution.
In the face of such an invisible killer who disappeared without a trace, is there nothing we can do? In fact, the country has begun to pay attention to the air quality inside the car, and there are corresponding evaluation procedures. From next year, 65438+ 10 1, the national "Guidelines for the Evaluation of Air Quality in Passenger Cars", will become a mandatory standard, and another evaluation system-China Eco-car Evaluation (C-ECAP) will also be implemented. In fact, it pays attention to three things: health, energy saving and environmental protection, and evaluates it with intuitive and quantitative grades-platinum.
In this evaluation, the air quality inside the car belongs to the most important item of health evaluation. Moreover, according to the evaluation principle of C-ECAP, the evaluation vehicles are randomly selected, not sent for inspection, and the evaluation vehicles are determined without prior notice, thus ensuring the fairness of the inspection process.
Among the evaluated models, only four models, namely, Dongfeng Citroen C4 Sega, Dongfeng Peugeot 308S, FAW Toyota Corolla Twin Engine and FAW Volkswagen Golf, won the highest level of White Gold Award, among which only one of the mainstream cars is Dongfeng Citroen C4 Sega. If we only look at health, C4 Sega scored 36.7 out of 40, which is the highest among the four white gold medal models, while the other three models are higher than C4 Sega in terms of price and level.
In the indoor air quality score with the largest proportion of health, C4 Sega scored 965,438+0.3%. In contrast, the scoring rate of golf, which also won the white gold medal, was 8 1.3%, while the scoring rate of Corolla Twin Engine, as a hybrid vehicle, was only 76.2% in indoor air quality, and it scored high in the total score only because of the low exhaust emissions brought by the hybrid system. This just shows that C4 Sega attaches great importance to the air quality inside the car.
Although the evaluation of C-ECAP is not mandatory at present, considering that the in-vehicle health has been paid more and more attention, the evaluation results are still of great reference significance. Moreover, don't think that this evaluation is very lenient. Before the introduction of the standard, China Automotive Technology and Research Center conducted a bottom-up test, and indicated that only about 22.07% of the products tested from the bottom up could obtain C-ECAP certification, while 77.93% could not obtain certification at all. Although the pass rate is so low, the standard has not been lowered. Therefore, being able to get the highest evaluation is a great affirmation of the health of C4 Sega vehicles.
It is worth mentioning that C4 Sega, which got the highest evaluation of in-car health, lowered the official guide price by 5438+0 1.2 million yuan in June, and the entry-level model has reached less than 1 10,000 yuan, achieving a win-win situation in quality and price, and its competitiveness in mainstream family cars has been significantly improved again, further establishing the benchmark position of in-car health quality of Dongfeng Citroen.
The air quality inside the car can't be ignored, so we must nip the killer of vehicle air pollution in the cradle from the beginning, and add the health inside the car as an important indicator to the consideration of car selection, so as to choose those models with good air quality and health.
