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.

Technology development under pressure Achieving major cuts in CO2 emissions and fuel consumption continue to be the big challenges facing the European automotive industry. But are the targets realistic, can emerging technology deliver solutions, is driveability likely to suffer, and will the end-user face higher costs? Pulling power The European industry is creating more (or at least as much) with less for the latest-generation powertrains. Chassis evolution Is it time for suspension system designs--increasingly costly to develop--to be standardized to conform to the ride and handling requirements of particular types and segments of cars instead of constantly being re-invented? The mere idea is anathema to some, but tempting common sense to others. Creature comforts Priorities for interior design are many and include increased safety, reduced noise, greater comfort, less complex ergonomics, and more systems support for the driver.
