- Abstract:
- Hydrogen is one of the favorite substitute for fossil fuels due to various properties including the flammability, ubiquity, and easy extraction from plain water. These properties have made it an appropriate alternative source of energy that can be used in internal combustion engines. Compared with fossil fuel energy, in addition to much lower emissions, hydrogen has proved to be much more efficient when applied as a clean source of energy. The main purpose of the present project is to study the effect of applying hydrogen on performance of compression - ignition as internal combustion engines as an alternative fuel. These studies encompass the results derived from the experiment of using hydrogen in the pure form and/or combined with different amount of LPG. CHEMKIN and Theoretical model is used to get predicted results. In this model a reciprocating internal combustion engine is simulated to study engine performance such as Instantaneous in cylinder Pressure, Fuel Consumption , Temperature, Thermal Efficiency, Mean Effective Pressure, Volume efficiency and polluting emissions. In the end, the predicted results obtained from the model is compared with the existing experimental data published in the literature in order to measure the accuracy and competency of the model .
