Abstract(E) | In order to protect the environment, the engines should be fuel-efficient with zero emissions, this is possible by using lean-burn engines as the combustion temperature is less and NOx emissions are reduced. SI engines have a narrow window for equivalence ratio thus it mandates for alternate fuels such as compressed natural gas (CNG) and hydrogen This experiment is conducted on a single-cylinder, digital three spark-ignited electronic fuel injection (DTSI-EFI) high-speed engine using gasoline, CNG and Hydrogen as fuels by varying the equivalence ratio ( ). Gasoline and CNG fueled engines achieved the highest power at Φ=1 and maximum brake thermal efficiency (BTE) at lean conditions, however, there is a reduction in the power output on lean and rich conditions. While operating the engine at lean condition H2 fueled engine released the lowest emissions. At a low equivalence ratio, the maximum combustion pressure, cumulative heat release rate and exhaust gas temperature are reduced. This is because lower Φ values decreased the flame development angle and total combustion occurs with low flame speed. |
