SORL Awarded Patent for New Electric Air Dryer

ZHEJIANG, China - SORL Auto Parts, Inc. (NASDAQ: SORL) ("SORL" or "the Company"), a leading supplier of brake and control systems to the global commercial vehicle industry, today announced that the Company obtained a patent in the People's Republic of China ("PRC") for a new proprietary electric air dryer that is specifically designed for new energy electric buses and specialty commercial vehicles. Equipped with an internal electronic control unit to achieve continuing desiccant regeneration, SORL's new electric air dryer has a prolonged useful life and improves the working environment of the vehicle's air control system. As a result, the dryer extends the operating life of the entire air control system and improves the vehicles' safety performance. The patent will be in effect from 2012 through 2030.

Desiccants in the air dryer are used to absorb moisture and dust to make sure the compressed air is clean when it goes into the air control system. Eventually the desiccants can become full of moisture and dust so the dryer becomes ineffective. Desiccant regeneration prevents moisture and dust saturation to ensure continued dryer operation.

A traditional air dryer controls desiccant regeneration through the cut-off pressure within the drying cylinder. However, due to the higher consumption of gas, some municipal buses cannot generate sufficient cut-off pressure over a long operational period, thus rendering the dryer ineffective. The functionality of the whole air control system is affected.

The new electric air dryer's electrical control unit consists of a built-in chip (ECU), a sensor and three electrical valves, providing additional control methods for the regeneration of the desiccants, such as cumulative time, differential pressure, etc. These new methods avoid the risk of not regenerating desiccants due to insufficient cut-off pressure, resulting in the continued operation of the air dryer and of the whole air control system.

Huaping Wang, the chief engineer of the SORL, commented: "China's automobile strategy is to develop new energy, electric vehicles. We are continuously making technological innovations and breakthroughs to meet or exceed the new demands of our clients. Through innovation we are maintaining our leadership position in the traditional brake and control systems as we provide new solutions targeting new energy vehicles to sustain our Company's growth."

The State Council issued the "energy-saving and new energy automotive industry development plan (2012-2020)" directive identifying that pure electric drive is the main strategic orientation of new energy vehicles. SORL's mission is to help industrialize pure electric and plug-in hybrid vehicles, promote and popularize non-plug-in hybrid vehicles, and enhance energy-saving combustion engine vehicles, to increase the overall technological level of China's automotive industry.

According to the plan, by 2015, the cumulative production and sales of pure electric and plug-in hybrid vehicles will reach 500,000 units. By 2020, the production capacity of pure electric and plug-in hybrid vehicles will reach 2 million units, while cumulative production and sales are expected to exceed 5 million units. Development of battery-powered and hydrogen-powered technologies will increase with the growing acceptance of new-energy vehicles globally.
