Heavy-duty designs on aftertreatment The introduction of stringent EPA 2015 regulations for locomotive/marine engines and IMO 2016 Tier III marine engines precipitated the need to develop large diesel engine aftertreatment systems. Gaining control of damping Strong nonlinearities of hydraulic systems and the unpredictable operating conditions of the specific application (e.g., uneven ground, varying loads) are the main challenges to the development of satisfactory general vibration damping methods and controls. Getting real about test cycles Fuel consumption of working machines is strongly influenced by machine specification, working environment, and operator behavior, therefore a mix of several test cycles is necessary. The case for Class 8 hybrids Hybrid technology may not be the best solution for all heavy-truck applications, but a Caron Engineering expert explains how it can still benefit Class 8 vehicles.
