You must answer all questions. Question 1:For the 90° V6 engine operating on a 4-stroke cycle with firing order 1-4-5-2-3-6 (see sketch), cylinders2, 4 and 6 are on the left bank; cylinders 1, 3 and 5 are on the right bank. 0 is the crank angle measuredfrom the TDC of cylinder 1. Use the following data:Distance between the planes of reciprocation of adjacent pistons = aMass of equivalent reciprocating unbalance in each cylinder = mAngular speed of the crank = w (clockwise when viewed from the end with cylinders 1 and 2)Length of the connecting rod = LLength of the crank = R(1) Calculate the primary and secondary shaking forces for each bank.(ii) Calculate the primary and secondary axial shaking couples for each bank.(ii) 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°leftbankrightbank4623, 41, 25, 68.

In a six cylinder in-line two-stroke cycle Diesel engine, the cylinders are pitched 150 mm apart. The crank length is 100 mm and the ratio of connecting rod to crank is 4.5. The reciprocating mass per line is 1 kg. The engine speed is 2121 rpm. Two possible firing order for this engine are 1-5-3-6-2-4 and 1-4-5-2-3-6. As a young engineer, you have been tasked to evaluate the most suitable firing order for this engine. Your evaluation should include examination of the engine for balance of primary and secondary forces and couples for the given firing order. Apart from examining the engine, you need to justify why one firing order is superior to the other.
