BLOOMFIELD, Conn. — Jacobs Vehicle Systems, a worldwide manufacturer of heavy-duty diesel engine retarding systems and valve actuation systems, has entered into a collaboration with internal combustion controls company Tula Technology.

The two businesses will work closely together to enable Jacobs to further develop cylinder deactivation technologies, which reduce engine fuel consumption and emissions, according to Robb Janak, director new technology, Jacobs Vehicle Systems

Jacobs introduced its Cylinder Deactivation (CDA) technology for medium- and heavy-duty commercial vehicle engines in 2018.

Tula, unusual among engine technology businesses in having headquarters in Silicon Valley, has licensed its Dynamic Skip Fire (DSF) technology onto  major automotive OEM gasoline applications.

The new working partnership between the two companies will utilize Tula’s DSF controls technology to support Jacobs’ expertise in diesel deactivation hardware development.

“Jacobs is very excited to partner with Tula to progress cylinder deactivation technology by combining our companies’ strengths,” Janak said. “Vehicle manufacturers are looking for new and improved technologies to comply with stricter legal limits on CO2 and NOx emissions. New test measures, such as Real Driving Emissions and CARB Low Load Cycle for heavy duty trucks are encouraging the adoption of smarter technologies that address these requirements. Cylinder deactivation is a great solution, technically proven and cost effective.”

With Jacobs’ CDA, Janak said cylinder deactivation mechanisms originally designed for the company’s High Power Density (HPD) engine brake are used in the valvetrain to disable the opening of the intake and exhaust valves. The hydraulically-activated mechanism is integrated in a collapsing valve bridge system for overhead camshaft engines or with a collapsing pushrod system for cam-in-block engines. When this is combined with disabled injection in selected cylinders, multiple cylinders can be deactivated as needed. At low engine loads with three of six cylinders deactivated, fuel consumption can be improved by up to 20%.

Janak said Jacobs’ CDA reduces emissions by achieving higher exhaust temperatures by maintaining after-treatment temperatures for optimal efficiency of SCR (Selective Catalytic Reduction) systems, even when the engine is in idle or low load operation. CDA also enables faster warm-up after engine start-up of the after-treatment system and minimizes cooling of after-treatment during coasting. CDA additionally reduces camshaft friction, reduces pumping losses in part-load conditions, and can reduce or eliminate use of the intake throttle, all of which yields overall improvements in fuel consumption while simultaneously increasing exhaust temperatures.

“Tula is pleased to support our industry partner Jacobs Vehicle Systems in its development of Dynamic Skip Fire-enabling hardware for the diesel engine marketplace,” said John Fuerst, senior vice president of Engineering at Tula. “Tula has developed an infinitely variable cylinder deactivation system, integrating advanced digital signal processing and software with sophisticated engine control algorithms. This technology reduces fuel consumption of gasoline engines by 6-15% on real world drive cycles; the collaboration with Jacobs aims to enable Jacobs to develop and demonstrate deactivation hardware required for diesel engines.”

AUBURN HILLS, Mich. — WABCO Holdings, a global supplier of braking control systems and other advanced technologies designed to improve the safety, efficiency and connectivity of commercial vehicles, Thursday said it has launched the WABCO Service Partner (WSP) program in North America.

Through this initiative, the company will certify vehicle service facilities that meet WABCO’s stringent technical and safety standards in the maintenance and repair of commercial vehicles. This launch represents an enhancement to the company’s aftermarket support offering, which was introduced at Heavy Duty Aftermarket Week (HDAW) earlier this year.

The WSP program creates a network of certified service facilities that have undergone specialized training by WABCO technical experts to attain extensive knowledge of the company’s products and services. Certified WSPs provide service, repair or replacement of WABCO’s suite of products for trucks, trailers, off-road equipment and other vehicles including buses and RVs.

“To become a WABCO Service Partner, a facility must excel in all areas of training and safety standards and be a proven industry leader in the work they do,” said Abe Aon, business leader, North America aftersales, service, support. “Customers can rest assured that if service is done by a WSP, it is done by a highly trained, WABCO-endorsed provider.”

Aon said the WSP program’s goal is to increase uptime for its customers, getting them back on the road as quickly as possible, and providing peace of mind that the service was done by a certified facility. All WSPs have access to WABCO Customer Care Center and expedited warranty claims handling to provide customers with quick and reliable service.

Michigan CAT, based in Novi, Michigan, is the first U.S.-based WSP in North America under this new program.

Michigan CAT is a unit of the MacAllister Machinery Co. of Indianapolis. Both companies are Caterpillar Inc. dealers. Michigan CAT has operations in eight Michigan cities and specializes in selling and servicing construction, off-highway and agricultural equipment, used trucks and trailers and fleet management solutions.

“We are pleased to welcome Michigan CAT as our first WABCO Service Partner,” said Aon. “By combining their commitment to service with their in-depth knowledge of WABCO products and services, Michigan CAT ensures a first-rate customer experience and the relationship will be excellent for us for the long term.”

WABCO expects to soon finalize the certification of two additional service providers and has begun accepting applications for additional shops that meet WABCO’s requirements to join the growing network. The goal is to expand the program to include more than 100 new WSPs by the end of 2020. WABCO currently has over 3,100 WSPs globally, with the highest concentration in Europe.

BLOOMFIELD, Conn. — Jacobs Vehicle Systems, a worldwide manufacturer of heavy-duty diesel engine retarding systems and valve actuation systems, recently celebrated the delivery of its 8 millionth engine brake.

This milestone delivery comes less than two years after Jacobs shipped its seven millionth brake, and nearly 60 years after the company’s first engine brake, invented by Clessie Cummins, was introduced to the trucking industry by Jacobs.

Since the first engine brake was produced, it took Jacobs 31 years to sell its first million engine brakes, which was initially an aftermarket product and sold exclusively in North America.

İn the late 1980s trucking industry interest in the product began to increase significantly and a shift was made to OEM factory installations, according to Steve Ernest, vice president, engineering and business development, who said geographic expansion soon followed and today Jacobs is selling and delivering engine brakes from its locations in North America, China, and Europe to more than 30 customers with locations in Europe, Asia, Africa, North America, and South America.

“This delivery is a fantastic achievement and is a testament to the success our customers have enjoyed around the world with Jacobs’ components,” Ernest said. “The next millionth brake shouldn’t be far off as we continue to find new solutions and technologies that will not only continue to enhance braking performance but also help our customers find new and effective ways to improve fuel consumption and reduce harmful emissions.”

Jacobs Vehicle Systems is headquartered in Bloomfield, Connecticut where is has a design, testing, and manufacturing facility, with support sites in Europe, Japan, and India as well as manufacturing facilities in Suzhou, China, and Brno, Czech Republic.

BLOOMINGTON, Ind. — FTR is reporting preliminary trailer orders for September at 19,000 units, the highest since February.

Trailer order activity rebounded from the recent doldrums as some fleets began placing orders for 2020.  Orders were up 81% month-over-month but minus 66% year-over-year. September’s net orders could have been even higher but were negatively affected by fleet cancellations of excess 2019 orders.

Trailer production should remain sturdy in September but somewhat off recent months with backlogs expected to drop for the ninth consecutive month, FTR said, noting that trailer orders for the past 12 months now total 264,000 units.

“This is a decent order amount for September. It indicates fleets are somewhat optimistic about 2020,” said Don Ake, FTR vice president of commercial vehicles. Orders should rise to healthy levels in October, as more large fleets place their 2020 orders. The increase in September orders signals the trailer market is becoming much more stable and should be settling into historic order patterns, after a turbulent couple of years.

“Trailer sales are expected to dip in 2020 after hitting record volumes in 2019. However, the forecast is still for a solid year based on moderate economic and freight growth, which should provide fleets with enough profits to buy new equipment.”
