Into the winter, the weather conditions are complex and changeable, with frost and snow falling, strong winds and fog, and the frequency of road traffic accidents has suddenly risen. Since October 2010, truck traffic accidents have frequently appeared in newspapers, resulting in 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 traffic accidents on trucks, the number one priority is driving violations, followed by vehicle mechanical failure. In the mechanical breakdown of various vehicles, brake failure occupies an absolute high proportion.

During the transportation of goods vehicles, they always face severe road conditions: long downhills, sharp corners, narrow mountain roads, and slippery ground. At this time, if the vehicle only relies on traditional brake pads, it needs to be stabilized. The driving speed will have to continue to step on the brakes for a long time; the weight of the heavy truck itself will be large, coupled with the weight of the cargo, the braking process will easily lead to overheating during braking, resulting in brake failure or even tire fire, a serious threat to drivers and the surrounding population Life safety.

Thousands of years of travel, family members worry. For heavy-duty truck drivers who are traveling around the clock, what worries their families most is driving safety. Is there any advanced braking technology that can improve the brake performance of the vehicle and control the severe brake accident?

Currently, in order to solve the safety problem of heavy-duty truck brakes, engine brake technology is widely used internationally. Its working principle is to accurately prevent fuel injectors from injecting fuel into cylinders through electronic control systems, and to change the piston's power stroke into a vacuum process. The engine that normally drives the entire vehicle becomes an air compressor that prevents the entire vehicle from advancing. It can effectively control the vehicle speed within a constant range, greatly reducing the braking distance and time, and avoiding the brake pads wear and overheat caused by long brake pedals. The road can be quickly braked and the slope can be safely downhill.

Among domestic similar products, the performance of Xi'an Cummins ISM11 engine braking system is second to none: technology is mature, operation is simple, braking is reliable, and fuel economy is saved. Widely praised by heavy truck drivers. The author had the privilege of understanding the Central Plains Committee: Xikang launched the ISM11 engine with an engine braking system on the Chinese market. It has undergone more than ten years of experience in the North American market, adapting to a variety of severe working conditions, and being mature and reliable with perfect matching of performance. It is a proven model that is truly proven; the use of the ISM11 engine braking system differs from conventional exhaust braking, and its operation is very simple, as long as the switch is turned on when it feels necessary to brake and it is loosened at the same time. When the clutch and throttle are engaged, the engine brake system starts working instantly; the clutch or throttle engine brake system stops working instantly, and the reaction time does not exceed 0.1 second; after the ISM11 engine braking system is turned on, the engine continues to provide resistance and braking power. Up to 326 horsepower, flat road conditions The vehicle is reduced from 90 kilometers per hour to 70 kilometers per hour, which is 9.8 seconds less than the same configuration heavy truck brake without an engine braking system. This helps the driver to effectively control the speed: Brake to live. It can be described as intimate and handy. It is no wonder that more and more older drivers are enamored of using the ISM11.

In addition to escorting driving safety, the ISM11 engine with a braking system has its cute “cheats”—effectively increasing the economy of the engine: the engine is not fuelled when the brake system is in operation, and is particularly suitable for the next long slope. Use; can also avoid long brakes, greatly reducing brake pad wear, significantly extended brake pad replacement cycle; its weight is only 25 kilograms, can replace the water irrigation, effectively reduce the vehicle's weight, multi-pull goods nearly 1 ton. The engine brake system is maintenance-free for life.

The author's mental calculations are as follows: travel distance of 1,000 kilometers, 15% of the way on the way to step on the brakes, such as the use of engine brakes to replace a 1 ton tank, the standard load of 100 km fuel consumption of 45 liters, oil prices by 6.5 yuan / liter, tons and kilometers The freight is calculated according to 0.3 yuan: After running down, the fuel cost is saved by 10*15%*45*6.5=438.75 yuan, and the goods can be increased by more than 975kg. The income is 0.3*0.975*1000=292.50 yuan. It would be 438.75+292.50=731.25 yuan less than a car without an engine brake system. Calculated on a two-by-one basis, one month down to the province of 731.25*13=9506.25 yuan, a year is 9506.25*12=114075.00 yuan, do not know not to, a calculation startled, but this saves the money of a small half of the tractor Ah! This is not to mention the cost of adding water to the water tank of the truck and the time cost it can bring. Compared to this, the engine braking system can be maintenance-free for life.

"Saving money and worry," the Xikang ISM11 engine adhering to the engine has always been strong, reliable performance outstanding advantages, more mature and reliable engine braking system, even more powerful, to provide safety for the majority of users, allowing you to drive A trip to save money and peace of mind.
