Engine and Performance Specifications

The RS50 uses a 5.9-liter naturally aspirated inline engine with a cast-iron block designed for durability under continuous load.

Key Engine Features:

• 5.9L liquid-cooled engine

• 1800 RPM operating speed

• Inline multi-cylinder configuration

• 12V starting system

• 850-amp cold start capacity

• Spin-on oil filter with relief valve

Operating at 1800 RPM reduces engine wear compared to high-speed portable generators. This lower speed significantly improves longevity, fuel efficiency, and maintenance intervals.

Fuel Flexibility: Natural Gas or LP Propane

Fuel selection can be configured in the field.

Fuel Consumption:

Natural Gas:

• 806.3 cu ft/hr at full load

• 481.6 cu ft/hr at half load

Propane:

• 8.84 gallons/hr at full load

• 5.63 gallons/hr at half load

This flexibility makes the Cummins RS50 Quiet Connect 50kW Generator 120/208 Volts 3 Phase ideal for remote properties, commercial buildings, and agricultural facilities.
