The Yuchai engine demonstrated was the 72 cm bore Wärtsilä 6X72DF

The engine demonstrated was the 72 cm bore Wärtsilä 6X72DF, installed as a technology demonstrator at the Aioi works of Japanese licensee Diesel United.
The engine was developed by WinGD and built in cooperation with Diesel United.
"Diesel United is our long term development partner in Japan; together, we have pioneered a considerable number of technical and product innovations. This large bore technology demonstrator installed in Aioi will enable us to showcase to customers worldwide the advantages of WinGD's unique low-pressure dual-fuel technology offering economic and environmental benefits for their businesses," says Martin Wernli, CEO of WinGD.
"It is our great pleasure to be the development partner of WinGD for the W6X72DF technology demonstrator," says Takashi Nakanishi, President of Diesel United. "We consider the low-pressure dual-fuel technology offers major benefits like low emissions and safe operation to the shipping industry which will make it a success in Japan and worldwide". So far 25 engines with this technology have been ordered.
The low-pressure gas admission system being pursued by WinGD on its two-stroke DF engines is based on the lean burn Otto cycle – i.e. ignition of a compressed lean air-gas mixture by injection of a small amount of liquid fuel.
MAY 4, 2015 — Winterthur Gas & Diesel (WinGD) recently held a demonstration run of the first large bore model from its new range of Wärtsilä brand X-DF low-speed two-stroke engines.
The X-DF technology features dual-fuel (DF) combustion technology with low pressure gas admission.
As the lifespan of vessels is usually measured in decades, and gas is expected to gradually replace liquid fuels in all engine applications, WinGD is also stressing the "future proof" aspect of its Generation X two-stroke diesel engines, which are pre-configured for a later retrofit with the low-pressure X-DF system.
The close cooperation between Diesel United and WinGD has existed since 1948 and many milestones in the history of marine engine development have been achieved jointly.
The demonstration of the Wärtsilä 6X72DF in Japan follows completion of testing and demonstration of the RT-flex50DF low-pressure dual-fuel two-stroke engine at WinGD's testing facility in Trieste, Italy. Together, the tests have confirmed the feasibility of bringing the benefits of low pressure gas admission to all of WinGD's Generation X two-stroke engines for marine propulsion applications.
The technology is characterized by its inherently low NOx emissions allowing a wide margin of compliance with IMO Tier III limits in emission control areas (ECAs) without exhaust after treatment, combined with high overall system efficiencies for low operating costs and significantly lower investment costs compared to competing technologies.
Reducing both first and operating costs, the use of low-pressure gas admission means that the gas fueling system on the X-DF engines does not require a high pressure electrically-driven compressor, considerably reducing energy consumption and giving the potential to dimension a ship's auxiliary plant smaller, saving first costs.
With the Generation X-DF engines, WinGD is responding to demand from the larger generations of LNG carrier vessels being built in response to a global trend to natural gas, as new reserves are brought into production. At the same time, the company is addressing demand from owners of vessels such as tankers and containerships of all sizes, considering LNG fueling.

Facing the new development situation, at Yuchai''''s industrial development debriefing on October 21, Yan Ping, chairman of Yuchai Group, set an overall tone of advancing industrial transformation and upgrading and starting a new undertaking.
Yan said, governments at all levels, including the People's Government of Guangxi Zhuang Autonomous Region and the Yulin Municipal People's Government, attach great importance to Yuchai''''s development and have offered practical support. Since the beginning of this year, relevant leaders of the autonomous region government and municipal government have visited Yuchai many times to give advice on Yuchai''''s future development. Upon elaborate planning by government departments and Yuchai, Yuchai''''s direction, objective and blueprint of "starting a new undertaking" have taken shape.

According to sources, to promote the rapid development of Yuchai, the municipal government will offer strong support in policy and resource reserves, allocate special land to Yuchai to conduct overall planning and lead the construction of Yuchai Industrial Park with large construction scale and top facilities. The park''''s establishment will further enhance the business level of Yuchai Group and promote the fast upgrading of Yuchai''''s industries, thus achieving the goal of starting a new undertaking. 

Hoifu Energy (00007 HK) announced that it would establish a joint venture with Yuchai Group for international investment operations. The company and Yuchai will hold a 51% stake and a 49% stake in the joint venture respectively, with a term of 15 years and a total share capital of 3 million US dollars including 1.53 million US dollars contributed by the company and 1.47 million US dollars contributed by Yuchai.
The joint venture will be mainly engaged in investment holding, covering engine, mechanical equipment, special vehicle, parts, energy and petrochemical product investment and sales.

Yuchai Machinery Co., Ltd. is a holding subsidiary of Yuchai Group. With an annual business turnover of over 20 billion yuan and annual engine sales of 550,000 units, Yuchai Machinery Co., Ltd. is China''s largest independent diesel engine manufacturer. The group concluded the JV agreement with the aim of establishing longstanding relations with its partner in joint efforts to seek opportunities and promising business projects.

It was a dam quandary.
Nearing 50 years ago, two brothers wanted a network of stock dams constructed on the family ranch so they could run more cattle — increasing the operation their dad had turned over to them.
But Emil and Ernie Baranko, on their ranch 20 miles north of Belfield, couldn't find anyone with the expertise or time to do it. So they did it themselves.
The first dam project took about a week — the brothers used two pieces of equipment, a bare-bones Caterpillar tractor and a scraper with no cab to shade them from the sun and heat, said Emil, now 80. The brothers followed a plan that the U.S. Soil Conservation Service had designed for them for a 200-by-300-foot dam, he said.
The dam, finished in 1967, is still there and operational, Emil said.
After the brothers built the dam, a parade of ranchers wanted dams and waterways for their places, too. So, the Barankos established an earth-moving company in a shop on the ranch, about a half-mile commute from the ranch house.
Ernie eventually focused on ranching, while Emil — who had attended college with aspirations of becoming a civil engineer before life and the military draft changed that — would end up overseeing the construction company. Eventually, beyond soil-conservation projects, he would see to fruition such jobs as construction of sections of Interstate 94 as well as airport projects.
But it was Emil's wife, Marcia, who was the backbone of the operation, "making sure I got something to eat," and raising the children, said Emil, who retired for about 15 years ago and is snowbirding in Mesa, Ariz.
One of the Barankos' three children, 41-year-old Glenn Baranko, the current president and CEO of Baranko Bros., remembers helping on company jobs while still in grade school.
Emil said Glenn would carry surveyors' stakes, run errands to the vehicles and perform various tasks, because Glenn "always wanted to be out there."
"I always knew that was what I wanted to do," said Glenn, a self-proclaimed heavy equipment/truck lover.
Glenn's office at the company's headquarters in Dickinson is adorned in heavy-equipment decor: In addition to family and dog photos, there are shelves of die-cast model trucks and hand-made wooden models given to him as gifts. On the walls are prints of vintage Harley Davidson motorcycles.
The company's biggest current undertaking involves 40 employees and is a two-year project that began last year: grading flat the acreage for a new railroad spur on a section of land between South Heart and Belfield for Great Northern Inc., an oil and gas land services company.
Glenn said the family's company — which mainly has North Dakota projects, but has worked in South Dakota and Montana — has all the work it can handle. With the current dip in oil prices, he said there has been a slowdown in new construction, but maintenance and environmental services are still steady.
The company has grown from the two brothers and two pieces of soil-moving equipment to about 200 earthmovers, trucks and trailers — plus the pickups and such — and employs about 100, increasing to 150 employees during construction season, Glenn said. The company still has the original shop on the ranch, as well as facilities in Center — including another company, owned by Glenn.
And there is the 22,000-square-foot Dickinson headquarters. It was substantially expanded in 2013 as the company had additional space needs because of the increase in business brought on by the oil boom, Glenn said.
Forward-thinking family
The company started its cutting-edge ways decades ago. Glenn said he remembers, as a kid, his forward-thinking dad going to computer classes.
Emil said it was in the late 1970s when, at an Oklahoma contractors' convention, he saw a crowd of people gathered around a particular booth, and he went to take a look. Being demonstrated was the future — a computer that could easy calculate a construction-job estimate and then immediately recalculate whenever the demonstrator changed the dollar price of items in that estimate.
Emil wanted that for his company, but couldn't find anyone in North Dakota to provide the service. So he sent two employees to Colorado for computer training, and when Dickinson State College offered computer classes, he took them.
Baranko Bros has continued incorporating other new technology — including, most recently, global positioning systems (GPS) and what Glenn calls "intelligent 'dozers" made by Komatsu, with a price tag each in the hundreds of thousands of dollars.
The operator of an "intelligent dozer" basically plugs in some information on a panel in the vehicle, points the equipment in the right direction and the bulldozer, with GPS-guidance and information from the project's computerized design plan, is pretty much on its own — its hydraulics on automatic, Glenn said.
Also, through GPS, Baranko Bros. can pinpoint the location of an individual piece of equipment and find out whether it's operating or sitting idle — enabling supervisors to know, among other things, if the operator is working or not.
The company has long-time customers who trust Barankos' work, Glenn added. His work day runs from about 7 a.m. to 7 p.m., and then he takes phone calls at night at home. He makes time to help with his son's Boy Scout pursuits, but doesn't do much more extracurricular activity.
Building the future
Recent projects include doing massive earth work for a new Watford City school, and also a major road project and the Watford City bypass completed in 2014. Glenn said that was a relatively easy job because they cut the road across prairie — so there were no traffic-control complications or the need to contend with the rebuilding of existing roads.
Glenn said a past challenging project was welding several thousand feet of pipe next to Nelson Lake near Center, and then placing and submerging the fresh-water pipeline across the lake.
Also, Glenn said a unique situation occurred years ago during construction of an Underwood-area dam when, in a wetlands area, they found a tremendous amount of bison bones. He said he was told Native Americans many years ago would run buffalo into a slough, where the animals would become bogged down and easier to hunt. The dam project was delayed while state archaeologists removed what was considered to be items of historical significance.
A big focus now is the company's environmental work, Glenn said. Baranko bought the assets of an environmental company last year and now specializes in removal of contaminated soils and saltwater, proving 24/7 spill response and related services. The company is also building a special-use landfill south of Belfield for oilfield waste.
Glenn said there is a waste landfill 25 miles north of Belfield, but there is a "definite growing need" for additional landfills to be placed strategically throughout the Oil Patch.
Glenn said, based on his experiences with oil companies, many of them are handling contamination situations responsibly.
"They are good stewards of the land," he said. The company early on moved beyond just stock dams, diversifying during the late 1970s oil boom, building oil-pad sites, roads and doing coal mine reclamation, power plant maintenance work and constructing landfills for fly ash.
As far as the next Baranko generation, Glenn said he doesn't know what his 11-year-old daughter or 9-year-old son will do. But his son's driving passion is very familiar to him.
"He's all boy ... all trucks," Glenn said

News of truck

"All the trucks under R&M have been rectified as standard. Whereas we were doing several intercoolers a month, it's now down to just a handful. That's why we issued the letter to customers that have not yet come forward, so we can close this issue down."
Davies also makes the point that nobody has paid for any high-pressure intercooler or EGR repairs resulting from this problem. "And where crank shaft bearing issues have been identified, we've covered them 100%, unless their workshops hadn't followed manufacturer's guidelines in terms of oil drain intervals."
MAN Truck & Bus UK – which wrote to all customers with Euro 5 D26 engined trucks, suggesting a maintenance check be carried out on the EGR (exhaust gas recirculation) system – says the problem with Van Hool coaches is unrelated. "If vehicles are maintained properly, in line with recommended intervals, then such damage is very unlikely," he says. "Build-up of residues is slow and, if the oil is changed when due, it rarely contaminates the oil enough to create a problem," he asserts.
Problem engines are mostly D26 Euro 5 EGR 440bhp. There are some 6,500 of those operating in UK trucks but, according to Davies, the issues are on pre-2012 built units, bringing the numbers down to some 3,000.
John Davies, MAN's head of UK service and support, explains that the numbers showing problems on buses and coaches are "proportionately very small", compared to those on its trucks.
Further, these engine issues are not the same. Being transversely mounted, the engines are equipped with cooling systems that are "entirely different" to those found in its trucks, he says, and it is the Van Hool cooling system that has been a "major factor in these failures". MAN believes it has been quietly very proactive. "Our dealers have been very aware of the importance of checking coolant strengths and levels, as well as checking oil for contaminants. We have also been using that information to go back to customers where we find problems and suggest they look at the quality of oils they're using," says Davies.
Says Davies: "Trucks are where we have had the bigger issue, the problem being around the high-pressure intercooler on Euro 5 engines built up to the end of 2011, which can leak slightly internally."
He explains that, if undetected over a long period, this leak can lead to residues in the engine oil, which can occasionally impact the lubricant quality enough to result in crankshaft bearing failures.
"The vast majority of those have already had rectification work done, because we've know about the problem since early 2012 when we started replacing the intercoolers with the later version," says Davies.



Maintenance nightmare

“Maintenance nightmare.” “We’re garbage guys. We’re inherently dirty, but we’re problem solvers. We don’t want to be polluters,” Ratto told me.
That’s how Lou Ratto, chief operating officer of a waste and recycling company in Sonoma County, Calif., describes the challenge of keeping his garbage trucks compliant with the state’s air quality standards. He’s since found what could prove to be an economical and eco-friendly solution to his problems. In August the Ratto Group will receive a garbage truck with a battery-powered electric motor, and a turbine generator that will extend the truck’s driving range. Traditional garbage trucks get awful gas mileage, but putting electric motors in them has proved challenging given concerns over the range of the batteries.
He’s seen maintenance costs for his older trucks rise 30 percent as he pays to clean the filters now required for the diesel engines. So a couple years ago he began exploring alternatives to diesel-powered trucks. Ratto looked at natural-gas options and hydraulic propulsion systems, but concluded they were either too expensive or didn’t fit the demands of his business.
Ratto has signed a contract with Wrightspeed to outfit 17 trucks of his trucks with its electric powertrains, which include its new turbine generator, called the Fulcrum. The turbine can run on fuels ranging from diesel to natural gas to propane and kerosene. Ratto will use diesel.
If things go well with the first truck this summer, Ratto will receive three more shortly thereafter.
“When this works I will have significant savings. How much, I’m not sure,” Ratto said. “I’m dying to find out.” FedEx has pilot-tested the technology and placed 25 orders for its fleetwww.yuchaiie.com 
Wrightspeed chief executive Ian Wright believes we’re at a turning point where turbine engines take hold of the market for land vehicles. The turbine charges the battery, which then powers the wheels. This is a crucial distinction, as using turbines in vehicles has traditionally been unappealing because turbines are so inefficient at low speeds. Since the turbine is charging the battery and not powering the wheels at idle, there’s no problem.
“Nobody had all the technology pieces lined up to make that work until now,” said Wright, who previously co-founded Tesla Motors. “There hasn’t been a turbine-generator engine until now that sort of got over the tipping point in terms of cost and efficiency, power to weight, multi-fuel.”



erhaps the most unique thing about the new mill is its all-in-one emissions hardware

Perhaps the most unique thing about the new mill is its all-in-one emissions hardware. Here the company has packaged the selective catalytic reduction module and the diesel oxidation catalyst in one canister with room left over for a DPF, when that becomes necessary to meet the Tier 5 emissions standards in a few years. Kohler is calling the KDI 3404 “Stage V Ready,” using the European term (Stage V). The current configuration of the 3404 doesn’t need a DPF to meet emissions regulations. When that day comes, probably around 2020, all Kohler will have to do to upgrade the line to Tier 5/Stage V is replace the DOC/SCR canister with a same-size DOC/DPF/SCR canister. This will make it easy for OEMs to incorporate the 2020 year model engines without having to reconfigure sheetmetal or engine bay layouts to make room for new hardware. The 3404 has all the choice components you need in a strong, compact, emissions compliant engine: four valves per cylinder, single stage turbo, high pressure common rail, solenoid injectors, and an electronically-controlled EGR valve that is liquid cooled by a water/air heat exchanger. Mechanical versions are available in countries with less strict emissions regulations. For applications where auxiliary power is needed, two power take offs (PTO) (SAE A and SAE B) are designed to simplify integration with the hydraulic system and keep the engine footprint as small as possible. What the company calls “bedplate” architecture on the crankcase and sub-crankcase) stiffen engine and resist twist and movement in the block. Counter-rotating crankshafts reduce noise and vibration. The new engine punches out 134 horsepower at 2,200 rpm and 369 foot-pounds of torque at 1,400 rpm. There are three additional versions of the engine with ratings of 120, 100 and 73 horsepower as well. The 73 horsepower version is the only one that does not use SCR as an emissions strategy. It only needs the DOC. - See more at: www.yuchaiie.com
