Parented from the legendary KTA50, the QSK50 EPA Tier 2 drilling power modules are designed, developed, assembled and tested inhouse by Cummins. Every component from the engine to the alternator is built to provide optimum performance, reliability, and versatility for oil and gas drilling applications requiring EPA Tier 2, China Stage 3 or non-emissionized standards. The complete power module package is backed by Cummins service network and warranty, ensuring greater uptime availability and increased rig efficiency.
The QSK50 engine uses the Cummins MCRS Fuel System technology to deliver ratings of 1480bhp (1103kWm) at 1200rpm and 1780bhp (1328kWm) at 1500rpm, while meeting US EPA Tier 2 and China Stage 3 Emissions standards. These engines are coupled with a form-wound alternator sized for drilling rig service with electrical ratings or 1000kWe at 60Hz and 1200kWe at 50Hz.
The QSK50 EPA 1200rpm (60Hz) Tier 2 drilling power modules are available with an optional Dual Fuel package that has been developed and tested by Cummins that allows customers to power their operations with 100 percent diesel or a mixture of diesel and natural gas whilst still meeting EPA Tier 2 emissions when a Diesel Oxidation Catalyst is installed.
The Dual Fuel controller provides dynamic system status and control with instantaneous feedback. Full FMEA (individual and with system integration), multiple alarm (high/low, shutdown) levels to improve uptime, cylinder bank balancing and Multipoint monitoring for the following:
- Load signal from power meter (current & voltage)
- Engine speed monitoring from engine controller
- Exhaust gas temperature monitoring
- Vibration monitoring
- Ambient temperature monitoring
- Reference gas pressure monitoring (ZPR to mixer inlet)
