The following data refers to the Otto-cycle: The stroke length is the same as the bore size. The clearance volume is 0,13 times the swept volume. The rotational speed is 3500 revolution per minute. The operation is on a four-cylinder, four-stroke principle. The indicated mean effective pressure is 700 kPa. The brake power is 85 kW with a mechanical efficiency of 85 percent. The relative efficiency based on the brake power circumstances is 54 percent. Calculate the following: = uz 3.3 3.4 3.5 The bore size and stroke length in mm.
