Paccar Adds Drive Axle, Updates Engines

Heavy Duty Trucking / October 2, 2016

In a step toward more integrated drivetrains in Kenworth and Peterbilt trucks, Paccar announced a new 40,000-pound tandem axle that saves weight and improves fuel economy.

This axle is “really helping us make steps toward an integrated powertrain,” Landon Sproull, Paccar vice president, told reporters at the American Trucking Associations Management Conference & Exhibition.

The new axle is designed for line haul, regional haul and pick-up and delivery customers, rated at 40,000 pounds and supporting a gross combination weight of 80,000 pounds. It offers ratios from 2.47 to 3.70 with engine torque compatibility up to 1,650 lb-ft and multi-torque rating compatibility up to 1,750 lb-ft.

The Paccar axle features a pinion-through-shaft design that simplifies power flow in the axle for maximum efficiency. A laser-welded carrier design eliminates internal fasteners, and reduces oil churn and weight. Overall the axle offers up to 150 pounds of weight savings, according to the company. Sproull did not specify the fuel economy improvements, noting that it would vary by application.

Kenworth and Peterbilt will begin offering the axle to customers in January 2017. It carries a warranty of five years or 750,000 miles.

Also available in Kenworth and Peterbilt trucks in January will be new power, torque and fuel efficiency enhancements to Paccar MX-13 and MX-11 engines for North America. Nearly 50% of Peterbilt and Kenworth heavy-duty trucks currently are produced with Paccar MX engines, according to Sproull.

Paccar increased the MX-13 engine’s output to 510 hp and 1,850 lb-ft of torque and increased the MX-11 engine’s output to 430 hp and 1,650 lb-ft of torque. The enhanced Paccar MX-11 engine also adds a new 335 hp and 1,150 lb-ft torque rating in the lower end of the power range. Paccar’s MX engines now deliver peak torque at 900 rpm for the majority of engine ratings, supporting increased performance and driving flexibility and supporting downspeeding strategies for fuel economy.

PACCAR preaches engines, axles and integration

Fleet Owner / October 2, 2016

Company may factory-fill MX engines with new FA-4 oil but won’t decide until tests are completed by year’s end.

Enhancements to the MX-11 and MX-13 engines, a new proprietary tandem axle, and how integrating those components together with the trucks built by Kenworth Truck Co. and Peterbilt Motors Co. will drive efficiency improvements were the high points of a press event held here by PACCAR at the American Trucking Associations ATA) annual conference.

Landon Sproull, vice president of powertrain for PACCAR and formerly chief engineer for Peterbilt, noted to reporters the company expects some 135,000 MX engines to be in operation in commercial trucks by year’s end, with the mix of MX displacements within Kenworth and Peterbilt orders at 50% or higher.

Sproull noted that 2017 model MX engines are getting several enhancements not only to comply with greenhouse gas (GHG) regulations but to deliver better “optimization” for Kenworth and Peterbilt truck customers:

The MX-13 engine rating will increase to 510 hp and 1,850 lb.-ft. of torque, with a weight trim of 50 lbs. due to the use of a higher performance turbocharger;
The rating for the MX-11 engine – introduced almost one year ago this week – jumps to 430 hp and 1,650 lb.-ft. of torque.

The MX-11 also gets a new rating for the lower end of its power range: 335 hp and 1,150 lb.-ft. torque.

A majority of the MX engine line’s ratings will deliver peak torque at 900 RPMs starting in January 2017, making them a better fit for downspeeding applications, said Sproull.

Other design enhancements to the 2017 model MX-13 and MX-11 engines include a new single cylinder air compressor, variable displacement oil pump, and variable speed coolant pump.

The MX engines will also come equipped with a new “single canister” aftertreatment system that reduces weight by 100 lbs.

Oil and fuel filter change intervals for the MX-13 and MX-11 engines will be extended from 60,000 miles to 75,000 miles for the 2017 model year; an extension PACCAR believes will save up to $1,000 per truck over 600,000 miles of operation.

Sproull added that PACCAR conducted 2 million miles of testing with its enhanced 2017 model MX engines and based on oil analysis is “confident” in the new extended oil change intervals.

“We’ve seen less soot in the oil and less degradation; that’s why we’re confident in the extended interval,” he said.

Though the new 2017-compliant engines are expected to deliver better fuel economy compared to current products, Sproull would not say by how much.

“I don’t want to commit to a percentage just yet,” he said.

Sproull added that PACCAR is also currently testing the new FA-4 engine oil blend in its MX products and may decide to factory-fill with it once tests are completed by year’s end.

“I believe we’ll recommend both oils [CK-4 and FA-4] for 2013 model year engines and beyond but we need to finish our tests first,” he noted.

Sproull also provided insight into a new proprietary tandem axle PACCAR will begin offering on its Kenworth and Peterbilt branded trucks in January primarily for line haul, regional haul and pick-up and delivery customers.

The new axle is rated at 40,000 pounds, supporting a gross combination weight of 80,000 lbs., and is expected to shave 150 lbs. off of total vehicle weight.

Sproull noted that his new PACCAR axle features a pinion-through-shaft design that simplifies “power flow” and reduces weight by eliminating a gearing and attendant fasteners.

“Fewer gears means less loss of energy from the engine to the axle; that’s the tick to efficiency,” he explained.

Thus integrating the new tandem axle with PACCAR’s MX engines will help drive further fuel efficiency improvements for Kenworth and Peterbilt customers, he said.

PACCAR’s new tandem also axle comes with a five year/750,000 mile warranty and offers ratios from 2.47 to 3.70 with engine torque compatibility up to 1,650 ft.-lb. and multi-torque rating compatibility up to 1,750 ft.-lb.

Peterbilt Adds Fuel-Efficient Day Cab

Heavy Duty Trucking / October 2, 2016

Peterbilt has added a day cab version of its aerodynamic, fuel efficient Model 579 Epiq day cab, officials announced during the ATA Management Conference & Exhibition.

It’s aimed at fuel-conscious day-cab fleet customers in regional, tanker and bulk haul applications.

“Fuel-efficient day cabs have been an underserved market up till now,” said Darrin Siver, Peterbilt general manager.

The Model 579 Epiq day cab offers up to 14% improved fuel economy compared to the predecessor Model 386 day cab, Siver said, and that number can be enhanced further by using a drivetrain featuring the Paccar MX engine and Eaton Fuller Advantage automated transmission.

Among the aerodynamic enhancements on the Model 579 Epiq day cab are:

- Multi-piece aerodynamic hood available in both 117- and 123-inch lengths;

- A three-piece collapsible roof fairing;
- Chassis fairings with rubber skirts from the quarter fender to the back of the cab and aerodynamic rubber closeouts under the sides of the cab;
- A three-piece aerodynamic bumper;
- A bumper air dam and bumper-to-hood seals;
- Front wheel closeouts and fender liners; and
- Chassis fairing kickouts.

Customers can specify the full aero package through Peterbilt dealerships for simplified ordering or customize it for specific needs, such as an aero bumper-to-back-of-cab package or an aero bumper-to-front-tandem package. The aerodynamic components and packages are also available through Peterbilt dealerships for aftermarket installation.

Peterbilt’s Model 579 Epiq day cab is available with the fuel-efficient Paccar MX-13 or MX-11 engine in a wide range of horsepower and torque ratings.

The three-piece collapsible roof fairing is an industry-unique design that in a few minutes allows the roof fairing to be lowered, according to Peterbilt. This allows the truck to be transported without the need to completely remove the roof fairing, as is common with most day cabs.

Other features of Peterbilt’s Model 579 Epiq package include low rolling resistance tires, the SmarTire Tire Pressure Monitoring System and a single horizontal exhaust configuration.

Kenworth rolls out a variety of enhancements

Fleet Owner / October 2, 2016

Its “Advantage” configuration will become the standard powertrain package for the T680 model in 2017.

Mike Dozier, general manager for Kenworth Truck Co., detailed a long list of enhancements and new offerings being introduced by the OEM this year and on into 2017 at the at the annual American Trucking Associations (ATA) conference.

First up: a new 52-in. mid-roof sleeper package for Kenworth T680 models in Advantage powertrain configurations, aimed at regional haul and LTL customers, that should help deliver up to a 6% improvement in fuel economy.

New aerodynamic elements on the 52-in. mid-roof sleeper help redirect airflow around the chassis and sleeper include a front air dam to redirect around versus under the tractor, mini “kickout” fairings to force air around the trailer and drive tires, and lower fairing extenders, Dozier said.

He added that the OEM is also going to start offering the FlowBelow Tractor AeroKit as an option for its T680 models starting in the first quarter of 2017.

That “Aerokit” features fairings fitted on each side of the truck between the T680’s tandem axles, a fairing directly behind the rear drive axle, and quick-release aerodynamic wheel covers that reduce turbulence within the wheel itself, according to Kenworth, with the fairings constructed of a durable yet flexible thermoplastic polyolefin (TPO) for long life.

Dozier added that Kenworth is also going to make its “Advantage” configuration the standard package for its T680 line. That configuration includes a PACCAR MX-13 or MX-11 engine mated to an Eaton Fuller Advantage series 10-speed automated mechanical transmission (AMT) plus Meritor MT40-14X drive axles rated at 40,000 lbs.

Dozier added that Kenworth is going to add the Bendix Wingman Advanced radar-based collision mitigation system as an option for its medium duty T270 and T370 models, noting that the Wingman system is “already popular with our Class 8 customers” and should be ideal in the heavy start/stop traffic flows experienced by medium-duty fleets.

Other new offerings and enhancements introduced by Kenworth include:

- Beginning in 2017, Kenworth will expand its onboard TruckTech+ diagnostic package and PACCAR Solutions portal to include a service management system powered by Decisiv that will allow fleets to monitor the service status for their individual trucks in real-time.

- The Kenworth power management system, available on its T680 and T880 models, will be upgraded to add cab temperature monitoring to the system’s auto start and stop capability.

- The addition of the Espar Airtronic D4 fuel-fired bunk heater that produces nearly double the BTUs [British Thermal Units] of Espar’s previous generation heater. The Airtronic D4 heater has a BTU rating up to 13,650, and is available for the Kenworth T680 and T880 specified with either the 76-in. or 52-in. sleepers

- The 8.9-liter Cummins Westport ISL G Near Zero NOx [oxides of nitrogen] emissions natural gas engine, rated at 320 hp and 1,000 lb.-ft. of torque, will become available as an option for the Kenworth T680 and T880 models in early 2017. NOx emissions from the ISL G are 90% lower than the current NOx limit of 0.2 gram per brake horsepower-hour, and meet the 2017 EPA greenhouse gas emission (GHG) requirements, Kenworth said.

Kenworth Offers 52-Inch Mid-Roof Sleeper on T680 Advantage

Heavy Duty Trucking  /  October 6, 2016

Kenworth has introduced the fuel-efficient T680 Advantage Package with 52-inch mid-roof sleeper for regional haul and less-than-truckload operations.

The new T680 Advantage configuration features an optimized powertrain with the 2016 Paccar MX-13 engine or Paccar MX-11 engine and Eaton Fuller Advantage series 10-speed automated transmission. This powertrain is combined with more fuel-efficient Meritor MT40-14X drive axles, rated at 40,000 pounds.

The 52-inch sleeper features aerodynamic elements to help redirect airflow around the chassis and sleeper to improve fuel economy. They include a front air dam to redirect around versus under the tractor, mini-kickout fairings to force air around the trailer and drive tires, and lower fairing extenders.

Other fuel-efficient features include Kenworth’s Predictive Cruise Control, Neutral Coast, Driver Performance Assistant and FlowBelow wheel covers.

“Our expanded Kenworth T680 Advantage lineup now provides three excellent Advantage choices – day cab, 52-inch mid-roof sleeper and 76-inch sleeper – to those regional haul, LTL fleets and truck operators in constant pursuit of achieving greater fuel economy and lower operating costs,” said Jason Skoog, Kenworth assistant general manager for sales and marketing. 

The 52-inch mid-roof sleeper is especially suited to regional hauling applications – including tank, bulk, flatbed, heavy haul and lowboy – where drivers may spend just two or three nights on the road during a typical week. The sleeper features a liftable lower bunk and upper storage units on the back wall with enough space for drivers to hang their clothes and jackets, plus an optional upper bunk for driving teams.

The optional passenger swivel seat expands the living space into the cab to provide more comfort for the drivers when parked. The design also provides sufficient head room for a driver or passenger up to 6-foot-4 to easily stand up between the seats. It features a 2.1-meter wide cab, with reduced interior noise levels, adjustable advanced suspension seats with climate control, air-assisted hydraulic clutch, ergonomic dash, the Driver Performance Center, and LED interior lighting.
