- A six-cylinder engine has a 1 5 3 6 2 4 firing order. Technician A says that after cylinder number 1 begins its intake stroke, the crankshaft will have to travel 240° before cylinder number 3 begins its intake stoke. Technician B says that when cylinder number 3 and 4 are at TDC, cylinders number 5 and 2 are at BDC. Who is correct and explain why? Technician A Technician B Both A and B Neither A nor Barrow_forwardWhat is the main function of the camshaft? Outputs the power created from the piston Move the piston up/down Involved in timing the opening/closing of the intake/exhaust valves with the position of the piston Transfers linear motion from the piston to rotational motion which can then be used to produce workarrow_forwardTrue False?
