Navistar has launched its Worldwide S13 Built-in Powertrain for the vocational market, providing it within the Worldwide HX Collection.

First launched for the on-highway market final August within the Worldwide LT and RH Collection fashions, the S13 Built-in Powertrain consists of three distinct elements — an engine, a transmission, and an aftertreatment system — designed and developed concurrently to make sure most integration.

“The S13 Built-in Powertrain is probably the most superior powertrain we have ever produced and the lightest vocational powertrain obtainable available on the market,” stated Mark Stasell, vp, Vocational Truck Enterprise, in an announcement. He additionally touted the advantages of efficiency, simplicity, serviceability, and working financial system.

The powertrain maximizes efficiency and capitalizes on effectivity made potential by way of its modular design in international collaboration with Navistar mother or father firm the Traton Group.

Extra Gas Effectivity, Fewer Regens

The 13L Worldwide S13 engine achieves superior gas effectivity and efficiency by way of a clean-burn combustion technique and a discount of friction and pumping losses, in accordance with Navistar.

The S13 engine is Navistar’s first engine designed with selective catalytic discount (SCR) know-how as the first emissions discount know-how. The absence of an exhaust gasoline recirculation (EGR) cooler on this engine permits for almost 100% of exhaust to move to the fixed-geometry turbocharger, equating to extra energy and improved engine efficiency. Moreover, the engine operates on low revolutions and excessive torque, which equates to fewer gas injections and fewer gas consumption, delivering as much as 515 hp and 1,850 lb-ft of torque.

The compact design of the Twin Stage Aftertreatment offers easy accessibility for serviceability, in addition to considerably improved emissions management and gas effectivity. To maintain temperatures at an optimum vary and lengthen service intervals, the aftertreatment system features a dual-stage SCR catalyst system in a one-box design.

Since an EGR cooler was eradicated from the combustion course of, much less soot and particulate matter are generated. This cleaner combustion cycle permits for prolonged service intervals and eliminates the necessity for the diesel oxidation catalyst (DOC) and energetic regeneration.

“Vocational vans usually spend fairly a little bit of time idling on a job website, which has traditionally required extra frequent energetic regens,” Stasell defined. “The aftertreatment system of the S13 Built-in Powertrain, mixed with the engine combustion technique, vastly reduces the necessity for each energetic and parked regens.”

Transmission, PTO Choices For Vocational Buyer Wants

The Worldwide T14 Transmission, a 14-speed automated handbook transmission, combines the transmission’s low vary and 6 reverse gears by way of using a planetary gear set.

The T14 combines two deep crawler gears and a large 26.7 total ratio to supply slow-speed maneuverability, distinctive startability and enhanced efficiency operating to and from the job website, stated Navistar.

Vocational-specific drive modes embody off-road mode, handbook mode and paver mode. These drive modes are enhanced with different vocationally targeted functionalities, similar to split-shaft mode and rocking mode (which breaks the truck free when caught.)

Shifting logic and built-in software program controls maximize effectivity and efficiency, leading to gear shifting that’s completely matched to engine revolutions. The T14 additionally makes use of an digital clutch actuator with controls built-in with the engine to ship quicker, smoother shifting.

A number of spec’ing choices can be found for numerous vocational buyer purposes, together with front-engine energy take-off (FEPTO), rear-engine energy take-off (REPTO) in addition to single and twin output transmission PTOs.

Multiple spec'ing options are available for various vocational applications, including frear-engine power take-off (REPTO), shown.  -  Photo: Navistar

All PTO choices are factory-installed at Navistar’s Built-in Powertrain Plant in Huntsville, Alabama, and carry the guarantee of the T14 transmission.

The S13 Built-in Powertrain additionally takes benefit of Navistar’s Diamond Logic electrical system to optimize physique integration, comfort and security options. This offers each chassis upfitters and prospects most flexibility, simplicity, and performance.

Warranties and Companies

The Worldwide S13 Built-in Powertrain consists of a number of buyer advantages outdoors of the product itself, together with seller built-in software program, built-in service merchandise and restore upkeep contracts.

Navistar’s linked answer, OnCommand Connection, comes normal on all Worldwide automobiles, together with these outfitted with the S13 Built-in Powertrain. Mixed with Worldwide 360, OnCommand Connection offers fleet monitoring and preventive upkeep scheduling to extend uptime. The OCC Go cell app permits fleets to watch their automobiles in actual time.

When spec’d for vocational purposes, the S13 Engine and Twin Stage Aftertreatment system comes normal with a two-year, limitless miles and limitless hours guarantee, and the T14 Transmission and factory-installed PTOs characteristic a three-year, limitless miles guarantee. A collection of further warranties and prolonged service contracts are additionally obtainable.
