Xi’an Cummins ISM11 Engine Leads Heavy Trucks into the Era of Engine Braking
In winter, the weather conditions are complex and changeable, with frost and snow coming, wind and fog, and the frequency of road traffic accidents rises suddenly. Since October 2010, truck traffic accidents have been reported frequently, with heavy casualties and shocking losses. According to the latest statistics from the Traffic Management Bureau of the Ministry of Public Security, in the analysis of the causes of truck traffic accidents, driving violations are the first, followed by vehicle mechanical failures. Among the mechanical failures of various vehicles, brake failure occupies an absolutely high proportion.
During the transportation of trucks, they are always faced with various severe road conditions: long downhills, sharp turns, narrow mountain roads, and slippery ground. At this time, if the whole vehicle only relies on traditional brake pads for braking, in order to control stability If the driving speed is high, you have to continuously step on the brakes for a long time; the heavy truck itself has a large self-weight, plus the load weight, it is very easy to cause the brake pads to overheat during the braking process, resulting in brake failure or even tire fire, which seriously threatens the driver and surrounding people. life safety.
At present, in order to solve the safety problem of heavy truck braking, engine braking technology is widely used in the world. Its working principle is to accurately prevent the injector from injecting fuel into the cylinder through the electronic control system, and change the power stroke of the piston into a vacuuming process, so that the The engine that normally drives the vehicle forward becomes the air compressor that prevents the vehicle from moving forward. It can effectively control the vehicle speed within a constant range, greatly shorten the braking distance and time, and avoid the wear and overheating of the brake pads caused by the long-term braking.
Among similar products in China, the performance of Xi’an Cummins ISM11 engine braking system is second to none, with mature technology, easy operation, reliable braking, fuel saving and money saving. Widely praised by heavy truck drivers. The ISM11 engine with engine braking system launched by Xi’an Cummins on the Chinese market has experienced more than ten years of experience in the North American market, adapting to various severe working conditions, mature and reliable technology, and perfect performance matching. Proven and mature models. The use of the ISM11 engine braking system is different from the traditional exhaust brake. Its operation is very simple. As long as the switch is turned on when the brake is felt, and the clutch and accelerator are released at the same time, the engine braking system starts to work instantly; step on The lower clutch or accelerator engine braking system stops working instantly, and the reaction time does not exceed 0.1 seconds; after the ISM11 engine braking system is turned on, the engine continues to provide resistance, the braking power is as high as 326 horsepower, and the vehicle speed is reduced from 90 kilometers per hour to 90 kilometers per hour on flat roads. 70 kilometers, which is 9.8 seconds less than the braking time of the same configuration heavy truck without the engine braking system, which can help the driver to effectively control the speed: as fast as you can, you must stop and brake.
In addition to escorting driving safety, the ISM11 engine with braking system can also effectively improve engine economy. When the braking system is working, the engine does not inject fuel, which is especially suitable for use when going down long slopes; it can also avoid stepping on the brakes for a long time. Reduce brake pad wear and significantly extend the brake pad replacement cycle. It weighs only 25 kilograms, which can replace the water irrigation, effectively reducing the weight of the whole vehicle, and pulling more than 1 ton of goods. The engine braking system is maintenance-free for life.
If the round-trip distance is 1000 kilometers, 15% of the journey needs to be braked, and the engine brake is used instead of a 1-ton water tank. The standard fuel consumption per 100 kilometers is 45 liters. After one trip, the fuel cost can be saved by 10*15%*45*6.5=438.75 yuan, and 975 kilograms of cargo can be added to increase the income by 0.3*0.975*1000=292.50 yuan. This minus one plus one trip is better than no engine braking. The car saving of the system is 438.75+292.50=731.25 yuan. According to the calculation of one trip every two days, it will save 731.25*13=9506.25 yuan in one month, and 9506.25*12=114075.00 yuan in one year. This is not to mention the cost of adding water to the water tank on the vehicle and the labor caused by it. Time cost, compared to the engine braking system, which is maintenance-free for life.
The Xi’an Cummins ISM11 engine, which saves money and worry, inherits the outstanding advantages of strong power and reliable performance of this engine, and has a mature and reliable engine braking system. Travel and save money.
