Yes, it is possible to use diesel and natural gas as fuel in the same dual fuel generator, but not simultaneously. In a dual fuel generator, the system is designed to operate on either diesel or natural gas depending on the requirements. However, these fuels are not mixed; instead, the generator switches between the two fuels based on availability, cost, or efficiency needs. The generator can start on diesel and then switch to natural gas or operate exclusively on one of the fuels at any given time.

For those interested in upgrading their DG (Diesel Generator) set to support dual fuel capability, the dual fuel kit for DG set available on CNG Power's website is a recommended solution. This kit allows for the integration of both diesel and natural gas, giving users the flexibility to switch between fuels and optimize their generator's performance and fuel costs.
