For the 90° V6 engine operating on a 4-stroke cycle with firing order 1-4-5-2-3-6 (see sketch), cylinders 2, 4 and 6 are on the left bank; cylinders 1, 3 and 5 are on the right bank. 0 is the crank angle measured from the TDC of cylinder 1. Use the following data: Distance between the planes of reciprocation of adjacent pistons = a Mass of equivalent reciprocating unbalance in each cylinder = m Angular speed of the crank = w (clockwise when viewed from the end with cylinders 1 and 2) Length of the connecting rod = L Length of the crank = R (i) Calculate the primary and secondary shaking forces for each bank. (ii) Calculate the primary and secondary axial shaking couples for each bank. (iii) What do you notice compared to the V8 engine analyzed in class? (iv) How easy is it to correct the unbalance on the V6? 90° left bank EEE 2 3 5,6 1,2 right bank HH H
