i am calculating the properties of an internal combustion engine, however, for efficiency i am getting a value of 0.2%.This seems too low to be correct. please see attached table of values and point out any figures that seem incorrect

thanks

What are your units of time, fuel flow rate and engine specific fuel consumption?
 
Time: Seconds
Fuel Flow Rate: kg/s
SFC: kg/kW/h
 
In calculating engine efficiency, did you multiply by 100 to convert a decimal to a percentage?
