A engine develops power output for each two engine revolution. * Your answer It is the difference in expansion amounts between the cylinder head and pushrod that effectively increases the space between the valve stem and the rocker's arm. * Your answer On a four-stroke cycle reciprocating engine, which strokes are both valves close? * Intake Power Ignition Compression Exhaust It represents the net power output of the engine at the crankshaft. * Your answer If the fuel/air ratio is proper and ignition timing is correct, the combustion process should be completed just after center at the beginning of the power stroke. * Your answer

Design a five-liter car engine that operates on a four-stroke cycle. Decide what the design speed will be, and then give the number of cylinders, bore, stroke, piston rod length, average piston speed, imep, brake torque, fuel used, AF, and brake power, all at design speed. All parameter values should be within typical, reasonable values and should be consistent with the other values. State what assumptions you make (e.g., mechanical efficiency, volumetric efficiency, etc.)
