A/f Ratio and BSFC

  1. Nov 12, 2011 #1
    I have few questions as i am bit confused

    Q1. I want to know what are the influence of the air/fuel ratio on engine output and Brake specific fuel consumption (BSFC).

    Q2. why bsfc increases at low engine output?

    Q3. why bsfc improves as engine output increases?

    Q4. what are the effects of early and late injection timing?
