An SI engine operating on a four-stroke air-standard cycle using stoichiometric gasoline is to have a maximum cylinder pressure of 11,000 kPa at WOT. Inlet pressure can be 100 kPa without supercharging, or it can be as high as 150 kPa with a supercharger. Design the engine cycle and pick a compression ratio and inlet pressure combination to give maximum indicated thermal efficiency. Also find out a compression ratio and inlet pressure to give maximum imep. engineering fundamentals of internal combustion enignes - pulkrabek.
One kilogram of air as an ideal gas executes a Carnot power cycle having a thermal efficiency 50%. The heat transfer to the air during isothermal expansion is 50 kJ. At the end of the isothermal expansion, the pressure is 574 kPa and the volume is..
a reactor setpoint wasincreased from 160 psig to 190 psig. the reactor pressure transmitter was recalibrated from 0-200 psig to 0-300 psig. what is the percent span for the old and new setpoints?
Evaluate thermal efficiency of the cycle
Important information about Multipal choice question on mechanics, A machine is supplied energy at a rate of 4,000 W and does useful work at a rate of 3,760 W. What is the efficiency of the machine?
how can this goal be achieved? are there alternative solutions which might also be effective?
design a computer programme using freudestein equation to synthesise a four bar linkage using three precision points also using more than three points.
In a tubular low pressure chemical vapor deposition (LPCVD) reactor, gas is introduced at one end at a rate of 75 torr-L/min. At the other end is a vacuum pump of a speed Sp. If the reactor must operate at 1 torr, what value of Sp is required?
What will the ratio of the angle of twist be to that of the hollow shaft if the maximum shear stress in the material of 75 N / mm ^2 and what is the ratio of actual permissible shear stress?
Design Problem - Piston and Flywheel : Analyze the motion of the crankshaft AB and flywheel for 0 ≤ θ ≤ 4Π (two complete rotations of the crankshaft, or all four cycles, beginning and ending at TDC), for different values of the four design paramete..
