In known pressurized aerosol dispensers with common valve and nozzle construction, that is, during the service life of the aerosol dispenser, especially when the dispenser is running out, the pressure in the tank decreases as the contents gradually run out, so the size of the resulting aerosol droplet tends to increase. The reduction of pressure will result in a significant increase in the size of the aerosol droplet, thus causing damage to the quality of the resulting spray.

It is the core strategy for the development of Dongfeng Commercial Vehicles to develop new energy, improve the industrial chain layout and accelerate overseas development. The development trend of high-power, heavy-duty, and high-end is vividly reflected in Dongfeng commercial vehicle products.
Not long ago, the Ministry of Industry and Information Technology released the deadline for the implementation of State IV emissions, that is, from January 2015 onwards, the country must implement the National IV diesel standard emission. The implementation time is consistent with the previous judgment of Dongfeng Commercial Vehicle's general manager Huang Gang.
In terms of China IV, Dongfeng Commercial Vehicles made early preparations. Three years ago, it had made technical upgrades to meet the requirements of commercial vehicle IV standards. Its National IV heavy trucks mainly use high pressure common rail and SCR technology.
At the recent Beijing Auto Show, Dongfeng Commercial Vehicle Co., Ltd. carried its six models and some powertrains. The Tianlong flagship, Dongfeng Tianlong dangerous chemicals vehicle and Dongfeng Tianlong quasi-heavy vehicle model Daguo IV standard, Dongfeng Hercules and Dongfeng Tianjin are Euro V models, and the emission standards are in line with international standards. It is the representative model for the expansion of Dongfeng commercial vehicle overseas market. . According to the Dongfeng Commercial Vehicle's staff, one right-hand drive model is for the Hong Kong market and the other is for the Brazilian market.
In addition, Dongfeng Commercial Vehicle independently developed an all-aluminum lightweight hybrid bus. To show that the product has high power and heavy load capacity, Dongfeng Commercial Vehicle Company brought DDi11 engine and Cummins 13L high-power engine.
In October this year, the "Dongfeng Team" set off for the world's top sailing events. This is a concrete action for the synergy effect between car companies and event organizers. It is an important part of the global market strategy of Dongfeng brand commercial vehicles. Dongfeng Commercial Vehicle Co., Ltd. actively participates in the Volvo Ocean Race, which will further strengthen the relationship between the partners.
Along the "Dongfeng" trajectory, Dongfeng Commercial Vehicle will also tell the world the wonderful story of Dongfeng Commercial Vehicle going to the world.
All this is done by Dongfeng Commercial Vehicles to open up its pattern in overseas markets. In developing overseas markets, Huang Gang paid more attention to the brand's presence in addition to paying attention to sales.
Due to the late start of the development of China's auto industry, the overseas market is basically the world of European, American and Japanese car brands. In recent years, with the rise of the Chinese automobile market, more and more Chinese auto brands have been exported to overseas markets, but overseas customers still have low awareness of Chinese car brands, and only the overall concept of “Chinese cars†is vague.
Therefore, Dongfeng Commercial Vehicles will pay attention to Dongfeng’s overseas brand building. In addition to establishing a unified overall external image, it also provides quality products and more comprehensive services. Through good after-sales service, more overseas customers have differentiated Dongfeng from the overall concept of Chinese cars and gradually established brand recognition.
In recent years, Dongfeng Commercial Vehicle has made important progress in the development of overseas strategic markets. If it enters the Brazilian market, it has strengthened its layout in markets such as Russia, Southeast Asia, and South Africa, laying the foundation for future work. At the same time, it also strengthened cooperation with domestic Chinese-funded overseas factory projects and jointly developed overseas markets.
As far as the domestic market is concerned, the performance of Dongfeng commercial vehicles has been very steady in recent years. In March this year, Dongfeng Commercial Vehicle Co., Ltd. sold more than 20,000 heavy-duty trucks, an increase of nearly 4.7% year-on-year. In the first quarter, the company sold 38,000 heavy-duty trucks, ranking the top position in the heavy-duty truck market. 
Pressure drop over the life of the dispenser varies with the type of spray used. The pressure drop can be 20-30% in the life of the dispenser if the injectant (e.g., butane) is present in the tank in both liquid and gas form. With this type of spray, more gas is released from the solution as the product runs out and the pressure inside the tank drops. In contrast, the total pressure drop can be 50 per cent or more in the case of the current injection, which is mainly or exclusively for compressed gases.
To facilitate the separation of droplets and to improve atomization, the valve housing of some known aerosol dispensers is fitted with one or more small holes through which the spray gas can be mixed into the liquid product as the liquid product is distributed through the valve. These holes are called gas phase taps (VPT).
