Study of performance of si engine fueled with supplemented hydrogen to natural gas

Abstract EN

In the near future, hydrogen will be required to supplement and eventually replace rapidly diminishing hydrocarbon fuels resources for internal combustion engines.

Engine variables effects like compression ratio, equivalence ratio, spark timing and speed on combustion properties, engine performance were studied in this paper, when hydrogen supplemented natural gas is used in variable compression ratio, single cylinder Ricardo E6 engine.

The results show that adding hydrogen to natural gas increase compression ratio, brake power and indicated thermal efficiency.

Also this addition reduces brake specific fuel consumption, volumetric efficiency and exhaust gas temperatures.

Optimum spark timing is retarded with adding hydrogen to NG.
