Description
Summary:The first and second law analysis was performed on a Single Cylinder, Multivalve, Electronic Fuel Injection, and high-speed motor fuelled engine with Gasoline and Hydrogen to assess energetic and exegetic performance. The engine was evaluated from 3000 rpm to 6000 rpm with both fuels. All tests are conducted at Wide Open Throttle conditions. The gasoline combustion was at stoichiometric, and hydrogen was lean burn. The most extreme energy and exergy efficiency was observed with hydrogen at 39.06% and 36.58% separately. Gasoline fuel 36.8 % and 34.6 % energy and exergy recorded at the same speed of 6000 rpm. The highest performance of hydrogen is due to high flame speed, and higher flame temperature. This shows that hydrogen converts the most extreme chemical energy to yield more power than gasoline. The coolant energy and exergy are additionally higher with hydrogen fuel. The lowest coolant energy is gasoline. The outcomes are additionally checked with combustion investigation of each fuel and found heat release rate was most extreme with hydrogen, trailed by gasoline. The greatest exergy destruction of 48.57 kW was with gasoline and followed by minimal with hydrogen. The greatest entropy is 49.45 W/K for gasoline and 22.22 W/K for hydrogenengines individually.
