Dear Narendra,

Write a balance stoichiometric combustion equation.

For example:

a*diesel+b*Biogas+c*Hydrogen +d*(O2+3.76N2) ------------> e*CO2 + f*H2O

Apply atom conservation to find d, e and f.

a,b and c are volumetric fuel percentage of respective compounds such that a+b+c=1.

Hi Narendra, are you asking how to determine the needed air or how to determine the fuel equivalents of each type fuel?

Narendra Khatri

Emmanuel Sandel : I was asking how to determine the equivalence ratio for the CI engine operating on multifuel (diesel, hydrogen and biogas) at the same time, not for individual fuel type.
