TowTimes.com - New Detroit DD13 Gen 5 Engine

[TowTimes]

The Detroit DD13, 13L engine is now available with new features and power ratings. Changes to the engine are focused around efficiency, robustness and thermal management, all of which contribute to a low total cost of ownership (TCO) and maximum uptime.

The DD13 Gen 5 engine is 60 lbs. lighter than its predecessor due to its new aftertreatment system (ATS) and is available with the Freightliner Cascadia for on-highway applications and Western Star 49X trucks for vocational applications such as construction and municipal jobs. Better packaging and more frame rail space ensures clear back of frame for Truck Equipment Manufacturers (TEMs) and upfitters.

ThermoCoasting, which was initially introduced with the Detroit DD15 Gen 5 engine, prevents aftertreatment cool down during a driving regen to keep the system at its optimum temperature and significantly reduces the need for parked regenerations. This is particularly useful for stop-and-go vocational/urban applications where maximum uptime is a must. ThermoCoasting also increases ATS performance and extends Diesel Particulate Filter (DPF) cleaning and maintenance intervals, maximizing TCO.

Many of the key components in the DD13 Gen 5 engine have reduced packaging complexity and are more durable to achieve an even higher level of reliability compared to previous generations.

DD13 Gen 5
With new vocational-focused ratings delivering up to 525 HP and 1850 lb-ft of torque, the DD13 Gen 5 is made for a wider range of jobsite applications including mixers, municipal, vacuum trucks and oilfield. These ratings have additional power at the upper end of the RPM band and more torque at the low end compared to the current DD13.

Additionally, the DD13 Gen 5 has been strengthened to handle higher compression ratios, while its new swirl piston design improves combustion and efficiency. A new asymmetric, fixed geometry turbocharger delivers rapid response while also using new thermal management strategies to keep heat in the aftertreatment and reduce the amount of system cool down. The new journal bearing turbocharger also features a Thermal Control Valve (TCV) that significantly boosts regen performance, allowing for more completed regens at most engine speeds and loads, especially when utilizing a PTO for vocational applications.

Fuel Efficiency, On-Highway Performance

The new ball bearing, fixed geometry turbocharger allows peak power and torque to be reached faster and delivers more fuel economy gains. Integrated Detroit Powertrain (IDP) ratings further slow engine RPMs while maintaining pulling power, reducing parasitic losses and wear for optimal fuel efficiency. The journal bearing turbocharger with the Thermal Control Valve (TCV) is also available without further downspeeding for on-highway customers.

Detroit Technology

The DD13 Gen 5 engine comes standard with the Detroit Connect suite of connected vehicle services, which provides fleets with remote access to vehicle diagnostic data as well as  fuel efficiency and safety performance insights. Through the Detroit Connect portal, fleet managers can access vehicle fault event and performance data to deepen their knowledge about overall fleet health. Access to the information can be customized so only information relevant to the user’s role is visible.

All Detroit engines are backed by the Detroit service network, which has more than 700 authorized service locations nationwide.
