Cat enhances G3600 series engines

October 14, 2014

  Caterpiller Oil & Gas has updated natural-gas fuelled G3600 engine line, the company’s flagship series for gas compression applications.

  It said the new G3600 gas engine platform will offer customers expanded fuel flexibility, a 5.6% power increase and greater altitude and ambient temperature capabilities. New G3600 engines also will have the latest ADEM A4 engine control unit.

  Engines included in the new design include the G3606, G3608, G3612 and G3616.  hey will be available in power ratings ranging from 1875 bhp (1398 bkW) (@ 1000 rpm to 5350 bhp (3990 bkW) @ 1000 rpm and 0.5 g/bhp-hr (NTE) NOx emissions.

  The expanded fuel flexibility allows operation with more power with fuels rich in heavy hydrocarbons as well as those with a high inert gas content. Other design improvements will improve fuel flexibility and increase power including a lower compression ratio, two stage aftercooler and new turbocharger. A new control strategy increases the load acceptance and robustness to fuel variation.

  Packaging of the engines has been simplified to include standard compressor oil cooler ports, standard JW heater ports, standard coolant and oil sample ports as well as engine mounted thermostats. The new exhaust insulation system features a stainless steel sheet metal structure with an inner insulation layer, minimized fasteners and grab handles.
