[ Preface ] Weichai Group, holding fast to innovation as a " bull's nose" or a gripper, adhering to the international vision, aligning with world first-class standards, and focusing on its main business, has build a strong and respected international enterprise.
[Text] Not long ago, Weichai Group delivered the first eco-tourist bus carrying the Weichai Euro VI powertrain to Hong Kong Daly Bus Group. This marked the European VI engine that Weichai has been developing for eight years has officially entered the high-end market. In order to meet the emission standards, a particulate filter system is added to the engine. Since the filter system cannot be disassembled, it is necessary to achieve self-cleaning by high-temperature combustion of the fuel injection, which imposes extremely precise requirements on the control system.

Less or more spray is not acceptable. If the spray is less, the carbon inside will not be completely digested. If the spray is too much, the temperature will be high and it will burn it. This is a core point. It is also the most difficult part of this technology.
ext] In order to smash this hard bone, the Euro VI engine and aftertreatment system on the Hong Kong bus has experienced more than 6000 hours' of bench test. Each experimental sample is worth more than 200,000 yuan, and an average of one such suite will be costed each week.

Each box needs to be loaded with forty or fifty such sensors. It is specially designed to measure the temperature distribution.A temperature point must be measured every centimeter to collect these reliability data, including doing some destructive experiments. After doing a destructive experiment on the box, the box and all the sensors were scrapped, and the investment and cost was great.
[Text] In the past ten years, Weichai has invested more than 15 billion yuan in engine research and development, and has formed more than 3,000 independent technologies and patents. This greatly speeds up product iteration and productivity. The intelligently transformed production line can meet the individual needs of customers, and one production line can produce 3,000 different types of products.

We now have more than 3,000 orders for the No. 1 Factory, and the orders for daily production can be as many as seven or eight hundred types. When we first built the factory in 2005, we assembled an engine in two and a half minutes. Now within ninety-five seconds, an engine can be assembled.
[Text] In the past ten years, the annual income of Weichai has increased from 50 billion yuan to 230 billion yuan, and the profit has increased from 2.9 billion yuan to over 10 billion yuan. Now, Weichai has already launched its endeavor to achieve its the 2020-2030 strategy.

What is the 2020 strategy? It means our traditional business will surpass the world-class when it is 2020, that means we will transform a chaser to a industry leading runner. By 2030, our new energy business will lead the industry.
