Engineering write-up
A professional farming operation requested a fuel-efficiency calibration across their John Deere 6.8L fleet to reduce operating costs during long-hour field cycles. We adjusted the injection timing and rail pressure maps to optimize combustion efficiency at mid-load, where the tractors spend most of their operating hours. Torque was increased by 45Nm to maintain PTO performance under load. Field testing over a 200-hour cycle showed an 11% reduction in fuel consumption with no change in reliability or fault activity.
