A4.2 l spark ignited v6 engine operates on a four-stroke cycle at 4200 rpm. the compression ratio is 10.5, the length of the connecting rod is 17.5 cm, and the engine is over square (with bore-to-stroke ratio of 1.3).at this speed, combustion ends at 15° atdc. calculate: a. cylinder bore and stroke length, b. crank offset, c. average piston speed, d. clearance volume of one cylinder, e. total volume of all cylinders at bdc. f. piston speed at the end of combustion, g. distance the piston has traveled from tdc at the end of combustion, h. volume in the combustion chamber at the end of combustion.
