Cummins on dual fuel

摘要

Cummins inc plans to produce dual fuel engines with ratings from 597 to 2610kW for high-horsepower markets. The first engine in the product portfolio, the QSK50 Tier 2 for oil and gas well servicing applications, will begin production in the middle of 2013, with other QSK Series engines to follow, including engines capable of meeting upcoming EPA Tier 4 Final emissions regulations. Cummins high-horsepower dual fuel engines will operate with common integrated controls, making a seamless transition from diesel fuel to dual fuel operation. By default, an engine will run on diesel fuel until the operator selects the option on the control panel to run the engine on a blend of diesel and natural gas fuel. The engine will switch to dual fuel mode and automatically select the substitution rate for the operator.
