fuel filtration is essential for maintaining engine
efficiency and helping to drive economic fleet
operation by minimising that downtime,”
Donaldson says.
With good filtration and water separation, fuel
cleanliness at the injector remains high and
engine performance and efficiency will remain at
consistent levels, according to the company. Poor
filtration will lead to excessive wear and damage
of injectors, reducing efficiency and putting
equipment at high risk of downtime.
“When we talk about fuel filtration and jobsite
efficiency, it's important to discuss bulk filtration
as well as onboard filtration,” DeGuelle said. “By
pumping fuel through a high-efficiency bulk tank
filter, any problems with fuel can be dealt with
before being pumped into the equipment. Also,
removing contaminants allows onboard filtration
systems to do their job better and remain
problem-free until regularly scheduled
maintenance can be performed.”
Donaldson recommends a four-tiered
approach for this:

equipment is the final failsafe against
contamination that happens within the tank;
n And, use effective onboard filtration as your
final line of defence against injector and fuel
system problems.

olls-Royce Power Systems and XCMG, the multinational heavy machinery manufacturing
company based in Jiangsu, China, just last month formed a strategic cooperation alliance to
further develop the Chinese domestic and export mining equipment markets, providing
optimised solutions to customers worldwide.
A strategic cooperation agreement was recently signed in Xuzhou, headquarters of XCMG, by
senior executives of the both companies. According to the agreement, Rolls-Royce Power Systems
and XCMG will commit to joint efforts in exploring opportunities to integrate Rolls-Royce Power
Systems’ MTU power and propulsion systems, including MTU Series 2000 and 4000 engines, into
XCMG equipment for Chinese local and international mining projects. This brings together both
parties’ technical strengths and business insights, in order to enhance product competitiveness
and gain market share, Rolls-Royce Power Systems said.
With annual revenue of $7.5 billion in 2018, XCMG is currently the largest market player in the
Chinese construction and industrial sector, and ranks sixth in the world’s construction machinery
industry, according to Rolls-Royce Power Systems. Rolls-Royce Power Systems has, since 2012,
supplied MTU S2000 and S4000 diesel engines to power XCMG’s XDE series mining trucks ranging
from 120-400 ton (109-363 t).
Both parties see great potential in further exploring the market with mining equipment built in
China powered by high performing, reliable MTU diesel engines that meet Chinese and global
emission standards today and in the future, according to Rolls-Royce Power Systems.
Andreas Schell, CEO, Rolls-Royce Power Systems, said: “It is a great pleasure to strengthen our
partnership with XCMG, a valued customer with a strong market position and business ambition.
The agreement demonstrates commitment of both our companies to deliver world-class solutions
to the world’s mining industry.”
Tobias Ostermaier, President, Rolls-Royce Power Systems, Greater China, said: “I am confident
that the agreement will allow better integration of MTU products and services into XCMG
equipment, to achieve higher efficiency and optimised support to customers. It will also enable
collaboration at different levels across each of our organisations to deliver highly completive and
compelling offers to the market.”
Li Zong, XCMG Mining Machinery, General Manager, said: “The win-win cooperation is aligned
with our development strategy to continue to enhance technology and market leadership at home
and abroad. The combined force of MTU and XCMG will allow us to leverage synergies and create
shared value.”
The two companies also agreed to collaborate on the validation and testing of new power and
propulsion technologies, including gas engines and hybrid solutions, as well as applications of
digital technologies, to drive low-carbon, sustainable development of the mining industry.

Komatsu and Cummins recently celebrated the
delivery of the 100th modular common-rail
system (MCRS) repower engine module to
partner Rio Tinto.
This program is aimed at delivering major
savings in fuel efficiency, more engine
horsepower and lower service costs.
Since mid-2017, Rio Tinto, Cummins and
Komatsu have been working together on a new
technology roadmap that will see Komatsu 830E
and 930E haul trucks – including autonomous
trucks operating in the Pilbara region of Western
Australia – upgraded with the latest Cummins
QSK60 MCRS Advantage Plus engines.
“This new technology allows the engines to
achieve higher horsepower with fewer
turbochargers, while service life between
repowers is predicted to be 36,000-40,000
hours, up from 28,000-36,000 hours, delivering
lower lifecycle costs,” Komatsu Australia said.
According to Glenn Swift, Komatsu’s GM
Western Region, the project reflects Komatsu’s
philosophy of advancing, through technology
and continuous improvement, the safety and
operational efficiency of its product lines.
“It demonstrates how we aim to continually
support our customers with their specific and
ever-changing requirements. This highly
successful project is testament to the approach
and technical ability of key people from each
company, working together initially to
demonstrate their faith in the product
capabilities – and which has been borne out by
the results achieved so far,” he said.
According to Andrew Hardy, Komatsu’s Project
Support Manager for Rio Tinto’s engine module
program, the delivery of the 100th repower
module is a significant milestone for a number of
reasons. “Apart from being the 100th MCRS
module delivered, the date of the installation,
May 27, is exactly 560 days since we delivered
the first MCRS module in November 2017,” he
said.
“And, from the installation of the first MCRS
engine module, Rio Tinto’s dump trucks have
been in service with this new engine
configuration for more than 26,500 days
cumulatively across the fleet, with the first truck
being in service for 555 days as of May 27, 2019
