The Cummins QSL8.9-G4 is a 235 kW prime / 258 kW standby diesel generator set optimized for prime, standby, and continuous duty in commercial, telecom, healthcare, industrial, and remote applications. Powered by the DCEC QSL8.9-G4 engine—a 6-cylinder in-line, turbocharged, charge air-cooled industrial diesel with high-pressure common rail (HPCR) and electronic controls—it delivers robust, stable power at 50 Hz, 1500 RPM while emphasizing fuel economy, low emissions, and ease of ownership.

Feature	Customer Benefit
8.9L 6-Cylinder Turbocharged Engine with HPCR Fuel System	Outputs 235 kW prime / 258 kW standby in a durable package; ~210 g/kWh efficiency saves 15–20% fuel vs. mechanical models, ideal for extended runtimes.
235 kW Prime / 258 kW Standby @ 50 Hz	Handles medium-heavy continuous loads up to 500 hrs/year with 110% overload for 1 hour; perfect for hospitals, telecom hubs, or small factories without excess capacity.
Fuel Consumption: ~210 g/kWh @ 100% Load	Approx. 65 L/hour full load; strong partial-load economy (220–235 g/kWh) lowers OPEX and extends fuel autonomy during outages.
Electronic ECU Governor & Advanced Controls	Ensures ≤5% frequency and ≤±1% voltage regulation; fast response protects sensitive IT, medical, and telecom equipment from instability.
Brushless Alternator (Stamford/Leroy Somer)	<2% THF, ≤6-second recovery, up to 84% efficiency; minimizes harmonics and maintenance, delivering clean power for precision loads.
500-Hour Service Intervals	50% fewer stops than 250-hour units; 16.4 L oil, ≤4 g/kWh oil burn—saves labor and boosts uptime by 30%.
EPA Tier 3 / China III / Euro III Compliance	No aftertreatment required; simplifies permitting and reduces TCO while supporting global fuel flexibility.
Open-Type: ~3,200 × 1,150 × 1,750 mm, ~1,900 kg	Fits tight spaces—rooftops, containers, trailers; enhances mobility for construction and mobile power needs.
Soundproof Canopy Option (~70–75 dB(A) @ 7m)	Meets urban noise limits; low vibration suits hospitals, data centers, and commercial zones.
24V DC Start with Battery Charger	Reliable cold-start to –20°C (with optional 2–4 kW heater); ensures instant emergency response in any climate.
Deep Sea / PowerCommand® Panel (Optional)	Auto start/stop, diagnostics, alarms, RS232/GSM remote access—enables unattended operation and predictive maintenance.
ATS & Paralleling Ready (PMG Option)	Seamless mains failover; scalable with multiple units for growing industrial or telecom loads.
50°C Ambient Rating, Water-Cooled	Full power in extreme heat (Middle East, tropics); low back pressure (≤10 kPa) allows flexible exhaust routing.
Cummins Global Warranty & Support	2-year/2,000-hour coverage, parts in 24–48 hrs; delivers lowest total cost of ownership and peace of mind.
