John Deere Power Systems has introduced two new categories to its Tier 3 engine family. The PowerTech E line of engines feature full authority electronic controls and a high-pressure common rail fuel system, which improves fuel mixing for more efficient combustion. The engines are available in sizes from 2.4 to 6.8 liters and power ratings from 45 to 200 horsepower. For lower horsepower applications, the Deere PowerTech M engines use economical designs and mechanical controls plus a new mechanical fuel system that generates higher injection pressures for efficient combustion. PowerTech M engines start at 40 horsepower and will be available in advance of the EPA Tier 3 requirements.
