Cummins Power, the powerful inner "core" of the dump truck

In 1973, at the pre-Trex truck factory, a 13.5-tonne R17 off-highway dump truck was built, and most of the time it worked in the Liss quarry in Aberdeenshire, Scotland.

In 2016, 17 Cummins and Terex truck apprentices began repairing the truck in the UK. The successfully modified car was exhibited at the Motherwll factory in Scotland in 2018 and in the recent Buxton, UK. The Hillhead exhibition has received much attention.

This 45-year-old Terex truck has been refitted and still works well. The Cummins N855 engine is highly regarded. This refurbished engine gives you a taste of Cummins power and reliability. Once again, the gaze is focused on this "big monster."

ISM engine

In the truck circle, the card friends are familiar with the Cummins ISM engine "million kilometers without overhaul", which is not only a good reputation, but also a true portrayal of the reliability of the ISM engine. In the front hall of Xi'an Cummins Engine Co., Ltd., there is a dismantled Cummins ISM engine exhibit. This engine has been running nearly 1.2 million kilometers (11,947,20 kilometers). Throughout the dismantling of the parts, we have to admit : ISM's superior reliability is truly well-deserved!

Whether it is the camshaft, the cylinder liner, or the push rod, the inner hole or the lock piece of the single arm of the rocker arm, all the light is as new as the new one. The most important thing is that the carbon deposit of the engine injector nozzle is rare, and the filter screen does not appear. Burnt marks.

In addition to the slight carbon deposit in the engine piston that was removed, some parts were slightly scratched, and most of the parts were basically intact.

This dismantled Cummins ISM engine was provided by Master Jiang of Xinjiang. In 2009, he purchased the ISM Shaanxi Automobile F2000 heavy truck. For this engine, he gave a very high evaluation: "The engine performance is very good, the power is very strong, the fuel consumption is also very low. From the purchase to 2015, it has been running more than 1 million kilometers. The engine has no maintenance except normal maintenance. Repaired. I am very satisfied with Cummins ISM!"

X12 engineering engine

Customers in the Yunnan-Guizhou region are deeply impressed by the reliability of Cummins Power. The person in charge of a coal preparation company in Liushui Shuicheng County, Guizhou Province, evaluated the power of the Cummins X12 engineering version: "The engine performance is stable, the power is strong, the fuel consumption is low, and the future choice of the dump truck power will be more recognized as the Cummins X12 engineering engine!"

The X12 engineering engine has been adjusted for the throttle and booster, resulting in a 10% increase in maximum torque and faster power response. At the same time, the strength of the crankshaft is also increased by 50% to transmit more powerful instantaneous torque.

In order to ensure durability and applicability, the X12 engineering engine is equipped with a three-stage fuel filter, engine chassis protection, and a fuel-saving switch designed for engineering vehicles.
