""

Cummins Turbo Technologies’ big step towards reducing emissions

CEC (Cummins Engine Components) launched its first e-compressor for fuel cell engine in Wuxi, China on Feb 1, 2024. This is a new milestone for Cummins Turbo Technologies and a big step forward in Cummins Inc.'s Destination Zero strategy for reducing carbon and other emissions. Destination Zero is Cummins’ strategy to go further, faster to reduce greenhouse gas and air quality impacts of our products. This also demonstrates Cummins’ commitment to lead the industry in the transition to a decarbonized future.

Features of the E-compressor for Fuel Cell Engine

The key characteristics of the e-compressor are low noise, high speed, and high efficiency. The e-compressor uses a 45kW high-speed motor with the maximum design speed of 110,000 rpm. It is applicable for 150 - 200 kW fuel cell engines and 240 - 260 kW fuel cell engines under turbine energy recovery.

Here are the features of the e-compressor in further detail:

  • Low-inertia rotor design that enables faster start-up and an improvement in acceleration performance. Low-inertia design comes from high pressure ratio design which keeps the package as small as possible.
  • Full blade impeller design in noise reduction and facilitates smoother operations. Since blade pass-through noise is primarily caused by the number of blades, this full-blade design has the potential to lower the frequency of blade pass noise to within safer limits.
  • High-efficient aerodynamic design utilizes less energy and improves the fuel economy. Cummins has used its hundred plus years of development experience to enhance the impeller efficiency based on the fuel cell requirements.
  • Low-thrust loading wheel design offers smoother rotation and higher reliability. Thereby optimizing the two-side impeller sizing to balance thrust load without performance trade off.
  • Robust containment design provides larger design margins from containment testing and improves product safety during the running condition.

Cummins also launched the first test cell for the new e-compressor on the same day

The test cell has been upgraded with dual phase controllable power supply, coolant system and optimized pipeline connections, enabling improved testing of performance and endurance capability for E-compressors. 

Cummins is scheduled to establish e-turbo testing capabilities later this year as part of a Phase II upgrade for this test cell. A separate air-cooling system will be implemented to expand the controllable range of airflow and enhance the turbine inlet system. E-turbo technology is poised to become the preferred choice for high-power node fuel cell development, and Cummins Engine Components (CEC) is actively engaged in its advancement. The establishment of this e-turbo test capability will facilitate rapid validation and product iteration for Cummins' e-turbo offerings.

Cummins Custompaks are being used for water management as Thailand struggles with its water crisis

Water crisis

Sixty Cummins Inc. CustomPaks are in service in Thailand as part of a critical water management plan aimed at easing the country’s water crisis – a crisis that has caused enormous economic and social damage and stirred conflict among communities.

Over the past several decades, Thailand has continually faced water problems caused by severe drought. Water reserves in dams and reservoirs are insufficient while water resources are often contaminated with toxins caused by urban communities and the industrial and agricultural sectors.

Severe flooding is a threat, too, at a time when the realities of climate change are hanging over the country.

As a result, the allocation of precious water resources, which must be shared among various stakeholders including new and existing industry, large and small agriculture, and cities and villages has become a flashpoint.

Kittithanapat Engineering Co. (KTP), has been involved in the water management system since 1996, working closely with authorities such as the Royal Irrigation Department, Department of Water Resources, Bangkok Metropolitan Authority and others.

600 hp CustomPaks

To help KTP meet its often urgent requirements, Cummins DKSH (Thailand) has recently supplied 60 Australian-built CustomPaks – 45 powered by Cummins’ X15 engine rated at 600 hp, and 15 powered by the QSL9 rated at 325 hp. These fully self-contained powerpacks are emissions certified to Tier 3.

The CustomPaks are coupled to hydraulically-driven, large-volume submersible water pumps sourced by KTP from US company Moving Water Industries (MWI); KTP is the exclusive distributor in Thailand for these MWI Hydroflo pumps.

Prior to Cummins’ involvement, KTP was using another diesel engine brand but service support wasn’t up to the standard required.

Long-serving KTP engineer Kittisak Thanasoot says Cummins DKSH’s reputation for technical and aftersales support along with the reliability of the Cummins product were a key reason behind KTP’s decision to specify the CustomPaks for the Royal Irrigation Department.

The ability of Cummins DKSH to respond to short delivery times was also important.

“Supplying large quantities of high horsepower diesel engines for emergency situations such as flash flooding can be a challenge for KTP,” says Kittisak Thanasoot.

“Responding to the needs of the government agencies to manage such problems in a timely manner and with least impact on communities, KTP has found the answer in our partnership with Cummins DKSH.”

Power, pride and passion

The switch back to Cummins power has been beneficial for iconic New Zealand company Uhlenberg Haulage. It's all about whole-of-life costs.

Uhlenberg Haulage is closing in on 60 years in business, having been founded in 1966 by Mike and Carol Uhlenberg.

Based in Eltham, Taranaki, in New Zealand’s North Island, the operation is today owned and operated by their sons Chris, Daryl and Tony Uhlenberg.

Describing the Uhlenbergs as “old school family truckies”, Daryl talks about the company’s time-honored journey with a definite tone of pride, especially the work of his parents in laying the foundations for what is today an iconic fleet in its own right.

Cummins Inc. made its debut in the Uhlenberg fleet in 1971 with an NH250 powering a second-hand Kenworth K923 used in logging. A second Kenworth, a new W924 with a Cummins NTC335, followed soon after hauling an LPG tanker.

The Uhlenberg operation today comprises 40 prime movers and a variety of trailing gear to cater for the myriad of a jobs the fleet is involved in.

A number of Peterbilts feature in the fleet although Kenworth is now the brand of choice with six new units to be delivered over the next 12 months to cater for business growth.

Cummins’ X15 Euro 5 engine rated at 550 or 600 hp is the preferred power specification, with 18 red engines currently in the fleet.

Whole-of-life support

“The switch to Cummins has been a very good experience for us. We have nothing but praise for the Cummins organization,” says Daryl.

“The whole-of-life picture is the key thing for us and we’ve got that nailed with the support we get from Cummins – parts availability, scheduled maintenance, life expectancy and in-frame rebuilds.

“So the red engines turn up, we run them to life, which is 900,000 to 1.2 million kilometers, and then Cummins does an in-frame overhaul in a timely manner. If there’s an issue, parts and support are close by.

“The support we get from Cummins Palmerston North is fantastic, second to none.”

Daryl recently looked under a Kenworth that was in the workshop for a service and was surprised to see no oil leaking from the one-million-kilometer X15. “I remember when I was a fitter we had to wear a raincoat when working under a truck,” he jokes.

Fuel agnostic

Acknowledging that the push to decarbonize is now “very real”, Daryl likes the idea of Cummins’ fuel agnostic concept where one base internal combustion engine, optimized to run on diesel, can also be customized to run on ultra-low and zero-carbon fuels like renewable natural gas and hydrogen.

“My father was a pioneer of linehaul trucking in New Zealand and he always embraced new technology. He was never scared of it,” he says.

“I tend to be a little more cautious but I can see where a 500 hp natural gas or hydrogen engine would work for us in short haul applications,” he admits. “We’re certainly willing to look closely at these alternative fuel technologies when suitable infrastructure is in place.”
