Unveiled at the 2018 Detroit auto show, the 2019 Ram 1500 has shed 100kg and added e-torque power. Available with a 5.7-liter Hemi V8 or a second-generation 3.6-liter Pentastar V6 engine, the 1500 uses mild-hybrid capability to recapture energy during deceleration to enable start/stop function as well as short-duration torque addition.

BorgWarner introduces new EGR coolers tech for LCVs

To support commercial vehicle manufacturers in meeting current and future emissions regulations, BorgWarner has developed an economical new series of multi-platform exhaust gas recirculation (EGR) coolers.

The new units feature a compact floating core, and unlike conventional solutions, which must be specifically designed for each application, the new modular cooler family includes four highly adaptable standard designs. BorgWarner states that this flexibility enables the new designs cover a wide range of engine sizes from 2.0- to 16.0-liter displacement. The new EGR solution is also said to offer high robustness against thermal fatigue and enhanced coolant distribution for durable performance even with minimum coolant flow, while also helping reduce NOx emissions.

"With lower production volumes and high durability requirements, the commercial vehicle segment needs an EGR solution that provides outstanding performance and reduces complexity at the same time," said Joe Fadool, president and general manager, BorgWarner Emissions & Thermal Systems. "Offering high flexibility and durability, our newly developed EGR coolers have already piqued the interest of several manufacturers that see the potential for a cost-effective solution to help meet increasingly stringent emissions regulations."

Featuring hybrid tube heat transfer technology and a floating inner core, BorgWarner’s EGR coolers are designed to resist high levels of thermal load. In addition, the system provides enhanced coolant distribution, which enables durable performance even with minimum coolant flow. BorgWarner integrated a thermomechanical damper into the design to facilitate complete decoupling of the shell and inner core components to absorb longitudinal and angular differences for improved durability.

The damper also provides some initial extra cooling for the inlet gas to reduce thermal shock and allows better gas distribution to the tubes to resist thermal fatigue. In addition, cooling the damper and inlet gas box reduces the overall temperatures achieved, which in turn helps lower thermal stress. When the system is operated at an exhaust gas temperature of 1,562°F (850°C), the inlet gas box temperature is kept below 392°F (200°C), compared to more than 1,292°F (700°C) without cooling.
