Cummins has revealed a new generation of ultra-low emission diesel engines that have been engineered to meet forthcoming EU Stage V emissions regulations. The engines include F3.8, B4.5, B6.7 and L9 variants with capacities from 3.8-9litre and spanning 75-321kW. Importantly, all have ditched EGR, creating a mechanically simpler package that delivers more power, more torque and lower fluid consumption, said Cummins - while maintaining the same capacity as the engines they replace.
“Removing EGR allowed us
World events are driving the new focus on fuel economy for diesel engine development Spiralling fuel prices have put a new spin on technological developments in the engine and driveline sector. Recent legislation has been pushing manufacturers to develop cleaner running engines that are quieter and offer drastic reductions in exhaust emissions. For the engine and driveline manufacturers, research and development aimed at reducing engine fuel consumption is in hand but the market conditions have placed fresh
The evolution of the diesel engine continues as ever more sophisticated technologies come into use - Mike Woof writes
A major focus for diesel engine suppliers is for the development of low emission technologies. Tough regulations are in force in North America and Europe with regard to emissions, a programme introduced to help reduce pollution from off-highway machines. These technologies are also being introduced in stages in other territories, with China now rolling out tougher regulations.
