John Deere Power Systems introduces three engines for use in gen-set applications — the PowerTech E 9.0L, 9.0L and 13.5L. The compact engines are targeted for the standby gen-set market, but will also be offered to the prime-power gen-set market. The PowerTech E 9.0L engine meets Tier-3 emissions regulations and has a maximum power rating of 315kW (422 hp). This engine features full-authority electronic controls, a fixed-geometry turbocharger and a high-pressure common-rail fuel system. These technologies offer improved cold-start performance and precise engine-speed control. The Stage II PowerTech 9.0L and 13.5L engines are new for 50-Hz gen-sets. The 9.0L engine has a maximum power rating of 304 kW (408 hp). The PowerTech 13.5L engine features the same technologies as the PowerTech E 9.0L except instead of the high-pressure common-rail fuel system it has an electronic unit injector fuel system.
