John Deere Power Systems introduces two new 13.5L generator drive diesel engines for emergency stationary gen-set applications in the 350- to 500-kWe range. The PowerTech E 13.5L Tier 3 and PowerTech 13.5L Tier 2 engines are designed to provide reliable, cost-effective standby power for the 60-Hertz market in the United State and Canada.

The PowerTech E 13.5L 6135HFG84 features higher-output PowerTech E ratings of 401 kW (538 hp) and 460 kW (617 hp) at 1,800 rpm, and meets key power nodes of 350 and 400 kWe standby power. The engine is available with a New Source Performance Standard emergency stationary label for the U.S. and Canadian markets, and is capable of achieving Tier 3 emissions levels as required by emergency stationary regulations.

The PowerTech 13.5L 6135HFG75 offers compact size, increased power density and lower heat rejection when compared to engines requiring a larger displacement, the maker says. It offers a power rating of 563 kW (755 hp) at 1,800 rpm and meets a key power node of 500 kWe standby power. Available with a NSPS emergency stationary label for the U.S. and Canadian markets, this model is certified to meet Tier 2 emissions levels as required by emergency stationary regulations for gen-set ratings above 560 kW (750 hp).

“The new 13.5L engines are the latest additions to our already extensive lineup of gen-set engines providing fast response for standby situations and exceptional load recovery in all applications,” says Xavier Adam, market planning manager for JDPS. “The PowerTech 13.5L models generate maximum power in minimum space for superior performance and installation flexibility.”

The PowerTech 13.5L generator drive engines feature a fixed-geometry turbocharger, electronic unit injector fuel system, 4-valve cylinder head, air-to-air aftercooling and full-authority electronic controls.
