Dongfeng Liuqi Longlong 609 equipped with EGR engine "paradox"

EGR Engine... Why is EGR Engine?

This is the first question that emerged from the minds of reporters after they saw Long 609.

On October 20th, 2009, Dongfeng Liuzhou Automobile's latest-generation medium truck platform faded away at the 6th China-ASEAN Expo, and was given the name “Chong Long 609”—609, taking the “2009 6th Generation Product”. ".

contradiction?

As early as a few months ago, there was a report on the new generation of Chinese card products from Long Long. For the time being, positioning middle-grade and high-quality products is the main product information obtained by reporters.

What is high grade? The basic judgement of most people is that they do not have a moderate appearance, push the common track, and focus on the urban medium and short-distance logistics or urban consumer special vehicle chassis market segments. In terms of appearance, there is no suspense in Liuzhou's Dragon 609. The shape of the Pa Lung 507 is enough to rival competing products; but on the power technology route, it is rather puzzling.

It is understood that Liuchuan Longlong 609 is still in the road test stage, that is, has been a logistics user in Nanning, as many as 20 orders. To this end, Liuzhou also deliberately held a grand ceremony for the delivery of new products on the same day.

However, the reporter noted that the vehicles delivered this time, the powertrain are Yuchai EGR medium-duty diesel engines. A card platform that was first positioned in the mid-to-high end market and the CK of the latest generation of models in the mid-to-the-medium card market, adopted the EGR route at the beginning of the listing. You know, its competitors, Dongfeng Tianjin D530, Auman Bing 3 Series and 5 Series, and JAC Geerfa L Series, from the beginning of the listing to the present, are mainly electronically controlled common rail or single pump technology. The route (typically represented by Tianjin and Auman Qibing) shows its uniqueness in distinguishing itself from the low-end mid-tier card platform.

Is the market positioning of Longxuan 609 changed, or is its product positioning and assembly configuration self-contradictory?

Problems followed.

Not contradictory?

At the unveiling ceremony of the new car, Liu Zhigang, Minister of Liuzhou Automobile Market, told reporters that the positioning of Longxuan 609 has not changed, and it is still taking the medium to high-end market line. Its “medium-grade” foothold is not located in the technical platform itself.

According to reports, the Long 609 Series was developed from the development of the Balong 507 heavy truck platform introduced by Dongfeng Liuzhou in 2007. Therefore, its technical indicators in all aspects are relatively close to heavy truck products. “This car is mainly used for safety and comfort. For example, the Bawang 507's cockpit frame structure continues to be used on the Long 609. The passive safety performance during collision is better. Because it is a heavy truck platform developed in the card, the long The cabin space of the 609 is also about 15% larger than the M10 cab of the light truck of the "Dragon Prince" of Liuzhou Automobile.

In the interview, the person in charge of the Liuzhou Automobile Technology Center further explained this. He believes that the reliability of the new Long 609 is a major feature of it. Due to the latest heavy-duty platform, and through rigorous 3D digital-analog development and optimization design, Chenglong 609 achieves higher vehicle reliability and lower failure rate. At the same time, in order to achieve the design goals of “European technology, safety and comfort” that were initially established in the second half of 2007, Liuzhou has also made considerable efforts in lightening the body and reducing engine noise. “After comparison and experimentation, The cab has less noise than the competition."

According to Liu Zhigang, the Chonglong 609 common rail product will be launched next month, adopting a pricing strategy that is slightly higher than that of the Auman Qibing and Geerfa, and is basically equivalent to Dongfeng Tianjin. The reporter's speculation is that this car will form a high and low match and division of labor with Liuzhou Automobile's “Dragon Prince”, and the short-term main market will still be Liuzhou’s dominant regions—South China, Southwest China, Jiangsu, and Shanxi. The goal is to gradually switch the Dragon Prince to the new generation of China Card platform.

Thus, in what appears to be "contradictions," Chenglong 609 has found its own market segmentation and clear positioning.

Extended reading

The Longsheng 609 is a third-generation dragon product, which is in line with the European high-end product Balong 507 heavy truck. The cabin uses the keel frame structure for the first time in the domestic light truck field, with semi-floating suspension as standard. High-strength steel plates are used as the key parts. The door and door frames are formed by integral stamping and the door has high-strength steel anti-collision beams. The shape of the tall, bold lines, and the unique design without side windows all reflect the European style of Long 609.

Longxu 609 is mainly equipped with Yuchai and Cummins two branded engines, including 4×2, 6×2 double forward steering and 6×4, power coverage of 120 to 220 hp, and no-load speed of up to 115 km/h. It is suitable for high-speed demand of modern logistics and transportation.

Because the back of the cab of the Long 609 is a vertical plane, the flat intake pipe is tightly attached to the cab, so that the design of the carriage can be maximized. The 9-meter long vehicle can be equipped with 6750mm long and 2400mm wide carriages.

The Long 609 galvanized steel plate has been subjected to cathodic electrophoretic paint, midway paint, metallic paint, varnish and many other coating process procedures, so that the Long Long 609 cab has strong corrosion resistance, and the metallic paint cab is not durable. Rusty. The lightweight double-frame girder with lightweight design technology combines the inner and outer beams closely and is strong and durable. It inherits the long-standing reputation of “Long-life Durable Truck”.

High-pressure Desorption Electrolysis

This series of equipment is oriented to the gold-loaded carbon in the gold cyanide carbon slurry process for gold desorption and electrolysis, and the gold adsorbed on the gold-loaded carbon is produced in the form of high-grade gold mud.

This series of equipment has 3 patented technologies and 5 proprietary technologies. Sodium cyanide is not used in the desorption liquid, which reduces the lean carbon grade below 100g/t. The key technology of this equipment is to ensure the balance of metal content, avoid the phenomenon of equipment "accumulation" and "floating gold", and ensure the stable and stable technical indicators of the equipment. The cost is low, and the content of technological advancement has been broadcast on the Spark Science and Technology column of CCTV in 2000. The technology passed the technical appraisal in 2003 and won the second prize of Science and Technology of the China Gold Association. The overall technical level is domestically leading. In 2006, it was designated as an energy-saving technology for gold production by the National Development and Reform Commission. In 2007, it was designated as an industry standard equipment by the National Development and Reform Commission. The equipment has obtained 3 Chinese patents, the patent numbers are: 01241537.5 01241538.5 200620029209.1
