Homework Help: Calculate the torque, total displacement volume, when stroke and bore are equal

  1. Dec 12, 2016 #1
    1. The problem statement, all variables and given/known data

    A six-cylinder four-stroke internal combustion engine, running at 2,200 rpm, outputs 120 kW of brake power. The stroke is equal to the bore. The brake mean effective pressure is 5.5 MPa. Calculate the torque, total displacement volume, stroke and bore.

    2. Relevant equations T=p/((2*pi*n)/60) <formula for torque , I cant find the rest of the formula , I googled them!

    3. The attempt at a solution
    So for torque I used the above formula t=120x10^3/((2*pi*2220)/60)=516.2Nm
    I have no idea to calculate the displacement volume , stroke and bore but I know the stroke and bore are the same. I checked YouTube , multiple sites and still didn't find any information to calculate these things with the numbers I have been given.
