Much like the GTA5.9 Gas Series, these light GTA8.3 spark ignited engines deliver world-class durability and reliability. Offering designs in both standby and continuous applications, these engines are fully integrated to meet your power needs. Our continuous gas engines guarantee continuous run time, while our standby engines offer extreme transient capability by picking up block load and meeting NFPA 110 requirements. While the GTA8.3 Gas Series offers the flexibility to run on fuels between 33MN (methane number) and natural gas including well-head gas and non-standard fuels, it also offers the ability to run down to 800 BTU/ft^3.
