when did ford start using the 6.7 diesel
Ford Power Stroke engine Emissions controls include exhaust gas recirculation, Denoxtronic-based selective catalytic reduction (SCR) from Bosch, and a DPF. Output was originally 390 hp (291 kW) and 735 lb·ft (997 N·m).[6] but shortly after production started, Ford announced that they made an update to the 6.7L diesel. The new engine control software makes the engine capable of 400 hp (298 kW) at 2,800 rpm and 800 lb·ft (1,085 N·m) at 1,600 rpm while achieving better fuel economy and without any physical changes to the engine. [7] The 2015 engines are rated at 440 horsepower (330 kW) and 860 lb·ft (1,166 N·m).[8] Ford claims the bump in horsepower is from a new turbo, new injector nozzles and exhaust improvements. For 2017, the torque has risen to 925 lb·ft (1,254 N·m) at 1800rpm, Horsepower remains the same..[9]
Ford F-Series In 1975, the F-150 was introduced in between the F-100 and the F-250 in order to avoid certain emission control restrictions. For 1978, square headlights replaced the previous models' round ones on higher trim package models, such as Lariat and Ranger, and in 1979 became standard equipment. Also for 1978, the Ford Bronco was redesigned into a variant of the F-series pickup. 1979 was the last year that the 460 big block engine was available in a half ton truck.
