With the introduction of Stage V/Tier 5 emissions regulations set for 2019-2020, depending on engine power output, FPT Industrial says that it will build upon its SCR-only strategy, remaining one of the few manufacturers not adopting Exhaust Gas Recirculation (EGR) to meet the standard. The Italian firm’s Hi-eSCR after-treatment system, already in use on Stage IV/Tier 4 Final engines, maximises in-engine combustion technology without using EGR. This saves weight, cost and space for the equipment manufacture

Cummins has taken a major leap forward with engine design as it ditches cooled exhaust gas recirculation for its newest heavy-duty six-cylinder engine platform launched at bauma – the 12-litre QSM12. As its Tier 4 Final/Stage 4 engine solution in the 250-383kW sector, the QSM12 benefits from higher efficiency air handling and an advanced in-cylinder combustion process, allowing a return to using a straightforward wastegated turbocharger.
