2. ABSTRACT
Diesel engines are prime movers for transport, agriculture, power house etc….
Diesel engines have high emissionrate&limited reserve. Hence we want to find an alternative fuel
Hydrogen is expected to be the most important fuel in near future
Hydrogen reduces the emission of HC,CO,CO2,etc…..

3. INTRODUCTION SCOPE AND BACKGROUND Limited reserve of fossil fuel
High vehicular pollution
Emission legislations getting strict
Dual-fuel Technology

4. What Is A Dual Fuel ENGINE?
A dual-fuel diesel engine is a diesel engine that utilize hydrogen as a supplemental fuel
Automatically able to run on 100% diesel when Hydrogen is not available
Reduces emissions , improve performance
Various gaseous fuels can be used

5. What Is A Dual Fuel ENGINE?
Air and Hydrogen enter the cylinder
The Air and Hydrogen
gas mixture is compressed
What Is A Dual Fuel ENGINE?
As the piston reaches top dead centre a reduced amount of diesel is injected into the cylinder
The air and hydrogen gas mixture combusts as a result of the diesel injection

6. WHY HYDROGEN IS BEST ALTERNATIVE FUEL?
No harmful emissions
Environmentally friendly
Efficient
Produced from many primary energy sources
NEED OF HYDROGEN DIESEL DUAL-FUEL
High auto-ignition temperature
Very low cetane number

7. How Can Hydrogen Burn Cleaner than Diesel?
Diesel fuel, Oil, Coal, the other fossil fuels, are chemically complex. They contain higher proportions of carbon and hydrogen.
Hydrogen gas is a Diatomic molecule (H2) - 2 protons, 2 electrons.
That's what makes hydrogen burn so cleanly.

8. EXPERIMENTAL SETUP Single cylinder 4 stroke engine
Eddy current dynamometer
Fuel burette-fuel consumption
5 gas analyser
Opacimeter- Smoke

9. Hydrogen Induction Circuit
Timed manifold injection (TMI) systems
Inbuilt flame arrestor
Emergency shut off valve
Flame trap
Mass flow rate of hydrogen kg/h
Timed manifold hydrogen induction circuit

10. procedure Diesel operation Fired at no load Constant speed-1500 rpm
Taken to full load through 20% increments
Hydrogen diesel dual-fuel
Mass flow of hydrogen set to .15kg/h
Taken to 80% full load through 20% increments

11. CONCLUSION CO emission was reduced by up to 67.5% and CO2 by 71%
Maximum reduction of smoke up to 64.28%
Reduction in specific energy consumption up to 41.4%
Successful to operate the existing diesel engine without any flashback of hydrogen
NOx emission get increased

12. FUTURE SCOPE Study working engine at various flow rate of hydrogen
varying the induction period of hydrogen for different cam profiles or dedicated electronic hydrogen injection systems
analyse the dual-fuel engine based on cost benefit
