3.  Dual fuel engines utilize a
combination of diesel and natural
gas to power the combustion
process.
 This innovative technology offers
increased efficiency and lower
emissions, making it a promising
solution for sustainable energy.
Introduction to Dual Fuel Engine

4. • A dual-fuel system is capable of
using two types of fuel at the
same time in a mixture.
• It usually cranks up on one type
of fuel, and a governor built into
the system gradually adds the
secondary fuel source until the
optimal mixture of the two fuels
is achieved for efficient running

6. Reductions
Operation Cost will fluctuate because of the operation conditions of
engines and the price level of fuel oil and natural gas in a project
site.
• Operation Cost Approx. 30%
• CO2 Emission 30% less
• Sox Emission 95% less
• Nox Emission 20% less
• (comparing with diesel oil firing)

7. Less operation cost
→ Main fuel : Natural Gas
 Environmental friendly
→ Drastic reduction of NOx, SOx & CO2
emission
 Stable operation
→ Pilot injection system
→ Operatable on either fuel of natural
gas or diesel oil
 Excellent dependability
→ Main component : Diesel engine
Clean combustion and Less
maintenance cost
Effective utilization of existing
assets
Features of Dual Fuel Engine

8. Application in Industries
Industries such as power generation,
mining,and manufacturing can benefit
from the adoption of dual fuel engines.
The ability to utilize a mix of diesel and
natural gas offers enhanced operational
efficiency and reduced dependency on a
single fuel source.

• In Car • In Truck

10. Conclusion
 The ignition delay in gas-fuel diesel engines of the dual-fuel type depends strongly
on both the quantity and quality of the pilot fuel used.
 Dual-fuel engine performance is improved with the employment of high cetane
number pilots.
 For stationary application, diesel substitution of 70% is possible by using dual fuel
engine which is quite considerable and also economical.
