Natural Gas Engine
Spark-Ignited Gas Engine - Uses spark ignition to burn natural gas and convert combustion energy into mechanical power for the alternator.
Electronic Fuel Control - Regulates gas and air delivery to maintain the required air-fuel ratio during changing load conditions.
Turbocharged & Aftercooled System - Supplies compressed, cooled intake air to support engine output and combustion performance.
Engine Monitoring - Continuously monitors key operating parameters including oil pressure, coolant temperature, and engine speed.
Gas Supply System
Gas Pressure Regulation - Reduces incoming gas pressure to the level required by the engine fuel system.
Gas Filtration - Removes contaminants from the gas supply before fuel enters the engine.
Gas Shut-Off - Stops fuel flow during generator shutdown and critical fault conditions.
Gas Train Assembly - Integrates the regulator, filter, shut-off valve, and connecting components into the engine fuel supply circuit.
Low-Emission Gas Power
Low Particulate Emissions - Natural gas combustion produces substantially lower particulate emissions than conventional diesel combustion.
Low Sulfur Emissions - Natural gas contains little sulfur, reducing sulfur-related exhaust pollutants during operation.
Lower Carbon Emissions - Natural gas generation produces lower CO₂ emissions per unit of electricity than conventional diesel generation when comparing equivalent electrical output.
Emission-Control System - Exhaust treatment equipment can be integrated to control regulated pollutants where required by the applicable emission standard.

FAQ
Q: What is the difference between a natural gas generator and a diesel generator?
A: A natural gas generator uses a spark-ignited gas engine, while a diesel generator uses compression ignition. Natural gas generation is suited to sites with an available gas supply and offers lower particulate and sulfur emissions.
Q: Can a natural gas generator replace a diesel generator for backup power?
A: Yes. A natural gas generator can serve as a standby power source for commercial, healthcare, industrial, and infrastructure facilities when a suitable gas supply is available.
Q: Does a natural gas generator need an ATS?
A: An ATS is required when automatic transfer from utility power to generator power is needed. It detects a utility outage, starts the generator, and transfers the connected load automatically.
Q: What happens if the natural gas supply is interrupted?
A: The generator stops when fuel pressure falls below the engine's operating requirement. A properly configured control system provides an alarm or shutdown signal for the fuel-supply fault.
Q: Can a natural gas generator power large electric motors?
A: Yes. Pumps, compressors, HVAC systems, and other motor-driven loads can be powered when the generator has sufficient capacity for both the running load and motor-starting demand.
Q: How is natural gas generator fuel consumption measured?
A: Fuel consumption is normally stated as the volume of natural gas consumed per hour at a specified electrical load. The actual consumption should be evaluated together with generator output and engine efficiency.
Q: Can a natural gas generator operate in parallel with the utility grid?
A: Yes. A grid-parallel system uses synchronization and control equipment to match generator voltage, frequency, and phase with the utility before connecting the generator to the grid.
Q: What maintenance does a natural gas generator require?
A: Routine maintenance includes engine oil and filter service, spark plug inspection or replacement, air-filter service, cooling-system inspection, gas-system checks, battery maintenance, and inspection of ignition components.
Q: How do you size a natural gas generator for a building?
A: Generator sizing should be based on the connected electrical load, maximum demand, motor-starting requirements, critical loads, and required operating mode rather than the building's total installed electrical capacity alone.
Q: Can natural gas generators be used for CHP applications?
A: Yes. A natural gas generator can be integrated with a heat-recovery system to produce electricity and recover usable heat for hot water, heating, or industrial processes.
