DESIGNPROBLEMS2-10. Design a six-liter race car engine that operates on a four-stroke cycle. Decide what thedesign speed will be, and then give the number of cylinders, bore, stroke, piston rodlength, average piston speed, imep, brake torque, fuel used, AF, and brake power, all atdesign speed. All parameter values should be within typical, reasonable values andshould be consistent with the other values. State what assumptions you make (e.g.,mechanical efficiency, volumetric efficiency, etc.)2-20. Design a six-horsepower engine for a snowblower. Decide on the operating speed,number of strokes in cycle, carburetor or fuel injectors, and total displacement. Givethe number of cylinders, bore, stroke, connecting rod length, average piston speed,brake torque, and brake power. What special considerations must be made knowingthat this engine must start in very cold weather? All parameter values should be withintypical, reasonable values and should be consistent with the other values. State allassumptions you make.2-30. Design a small four-stroke cycle Diesel engine to produce 50 kW of brake power atdesign speed when installed in a small pickup truck. Average piston speed should notexceed 8 m/sec at design conditions. Give the design speed, displacement, number ofcylinders, bore, stroke, bmep, and torque. All parameter values should be withintypical, reasonable values and should be consistent with the other values. State allassumptions you make.
