OBJECTIVE

To find out the best replacement for the fossil fuel if not at least can be offset the total fuel demand

INTRODUCTION

The hydrogen fuel is better:-

Its clean burning system

Low cost technology to produce hydrogen

It can be used in spark initiation, as well as compression engines

COMPARISON OF PROPERTIES OF HYDROGEN WITH GASOLINE

Hydrogen has a wide flammability range in comparison with all other fuels.

Fuel economy is greater and the combustion reaction is more complete when a vehicle runs on a lean mixture.

Hydrogen has very low ignition energy.

Hydrogen has a relative high auto ignition temperature.

High peak flame temperature due to higher enthalpy of combustion, 286 KJ/Mol energy

PERFORMANCE AND EMMISION CHARACTERISTIC

BRAKE EFFICIANCY

ENGINE POWER OUTPUT

The stoichiometric ratio is about 34:1. At this rate the hydrogen will displace 29%, while the air is 71%.

AIR FUEL RATIO

Figure 4 shows the variation of the brake thermal efficiency with the air fuel ratio for various speeds. It can be observed that the brake thermal efficiency is increases nearby the richest condition (AFR 35) and then decreases with increases of AFR and speed. The operation within a range of AFR from 38.144 to 42.91250 ( = 0.9 to 0.8) gives the maximum values for all speeds. It is clear that the hydrogen stochiometric air fuel ratio is within the band. Hence it is capable of producing higher power output invariably for all the speeds and loads.

CONCLUSION

It is the evidence of the study that using hydrogen enriched air as internal combustion engine is more advantageous. It provide significant on SI engine and CI engine on engine brake efficiency and brake power. NOx emission ids lowered it makes the engine move more leaner resulting the emmison of CO2,CO, and HC emits lower than other fuel.
