combustion of fuel problem

Recommended Posts

octane is burnt with 80% air


if it is theoritical air ,the equation wiill be



and form that equation we can find the coefficient a,x,y.

for x=8;

2y=18, so y=9;

2a=2x+y, so 2a=2*8+9, a=12.5


but when it comes to less than theoritical air there should be co present ,shouldn't it?

then what will be the equation



if i give some coefficient to co my question is how i can find the value coefficient of co here ?

i tried .lets see...

if we declare another coefficient d for co then




2y=18, so y=9;



we get 3 variable and two equation.but we need 3 equations to solve for 3 variable...

if you're sure with the equations then let's try...

First having equations less than the number of variables doesn't mean there is no solution.

I guess you should write d or x interms of 'a' then insert any number that satisfy the equation.
