Event 1 : At the beginning of January 2010, Shanxi Quzhou netizens sought help from the China Truck Network, saying that he had just purchased the Dongfeng Tianlong heavy truck and the Renault dCi11 engine. Due to the complexity of the local operating conditions, this engine has no engine brakes and it is not safe to operate. Due to the technical limitations of the local service station, there is no way to install it. Therefore, please contact the Chinese truck network to help the manufacturers and hope to install an engine braking device.
Follow-up: With the help of China Truck Network, Dongfeng Commercial Vehicle actively communicated with the user and arranged a special person in charge to handle the problem. Three days later, when the reporter called the Ganzhou netizen again, he had already arrived at Shiyan, and he was installing an engine braking device at the Dongfeng engine plant, which cost him 10,000 yuan. Although the price is high, he is very happy to think that this money is worth it.

Event 2 : On March 31, 2010, "Liberation J6 Aowei 6DM (11L) Series Heavy Truck Launching Ceremony was held in Wuxi Xichai Plaza.
At the conference, Qian Hengrong, the head of FAW Wuxi Diesel Engine Factory, emphasized that the engine braking device with independent intellectual property rights is the standard configuration of Aowei 6DM (11L) diesel engine, and the braking power is higher than that of diesel engines of the same grade.
Since many people do not know engine braking well enough, Qian Hengrong said: Engine braking refers to lifting the accelerator pedal, but it does not disengage the engine. It uses the compression resistance of the engine's compression stroke, internal friction force, and infeed. Air resistance forms a braking effect on the drive wheels. Its characteristics are three: First, due to the role of the differential, the braking torque can be evenly distributed to the left and right wheels to reduce the possibility of side slipping and tail flicking. The second is to effectively reduce the frequency of foot brakes. Avoid the use of brakes for a long time, resulting in brake friction plate temperature increases, brake force, or even lose its effect; Third, the speed is always limited within a certain range, is conducive to timely deceleration or parking to ensure traffic safety.
6DM engine adopts precise design and matching of engine brakes. At 2100 rpm, the braking power reaches more than 200KW, which is at the leading level in China, especially under the common working conditions of 1500 rpm engine, and the braking efficiency is higher; the vehicle is downhill over long distances. Without stepping on the brakes, the wear of the brake pads is significantly reduced, and the brake pads are guaranteed to operate at a relatively low temperature. This improves the safety of the entire vehicle and the reliability of the braking system, enabling the Liberation J6 truck to have a “safe heartâ€.
Xcear's independently developed engine braking technology

The liberation of the J6 aowei 6DM (11L) series heavy truck nationwide launching ceremony, Anhui users of the Jiefang J6 told the China Truck Network reporters have their own experience: When driving on the residua road, muddy ice and snow, it is easy to step on the brakes. Slipping is very dangerous. With the engine brake, it is very easy to stop the car and it is safe and easy. On the rough roads, the brakes are worn for a long time and the wear of the brake pads is very serious. Operating costs, 6DM engine standard engine brake device to solve this problem.
The engine's standard braking device will inevitably increase the process and cost, and because there is no clear requirement for the heavy truck engine to be equipped with a brake device, it increases the annoyance of those who want the engine brake. The following is the whole process of installing engine brakes by users in Luzhou:
1, the engine wiring harness to change. Because there are two solenoid valves on the brake, the original harness is not.
2, the exhaust valve spring to change.
3, is the nut on the valve rocker arm to change.
4, is to fix the injector nozzle wire to be replaced 5, is to install a 7 cm aluminum gasket on the cylinder head. Because the brakes on the valve bay are high, it is necessary to increase the height of the brakes by five.
6, is to change some necessary extension screws.
After the computer board is finished, it is refreshed again and some data of the engine brake is implanted (must be removed).
Looking at this process is a bit of a head start, but it is a must, and engine braking is essential for users.
Safety is an inevitable trend for the development of heavy truck technology in the future. Engine braking is a part of this trend. FAW Xichai sees this trend and also seizes the breakthrough point. The independently developed 6DM11 litre engine has a brake system as a standard and has changed passive safety into active safety. While enhancing its competitiveness, it has been truly dedicated. For the benefit of users.
In Xiao Bian’s view, Blessed Card users are blessed and do not need to experience the complicated process of the above users in Zhangzhou. congratulations!
