Lab 5 Reciprocating Engine Operation

A valve (sometimes called a swirl flap or tumbler valve) is locat The throttle opening is electronically controlled; the position of When the throttle is fully open, there's a more efficient air suppl Find the following components in the illustration: air filter air temperature sensor e intake manifold (tumbler) valve • mass air flow sensor e throttle control module (TCM)

I am having a hard time understanding C-E on this problem. For C, I know that Th>Ti>Tc. Does that mean that since ec= 1-Tc/Th and Tc is the lowest temp of the system, that it is indeed more efficient with both engines?  The other ones, I just don't know where to start.  Any help or explantions would be appreciated!

Automatic cylinder reciprocation is possible with this circult The cylinter continuously extends and retracts as long as the system is pressurized and valve A is activated. cylinder continues to extend until the ramp depresses the activation mechanism on Valve C. When Valve C is shifted, air is directed to the Retraction pilot of the four-way directional control valve. The pilot shifts the valve to direct air to the rod end of the cylinder. The cylinder begins to retract. The ramp moves off Valve C, which allows the Retraction pilot line to vent. The cylinder continues to retract until the ramp depresses the activation mechanism on Valve B This allows system air pressure to again activate the Extension pilot, beginning another sequence. The cylin- der continues to reciprocate as long as Valve A is held in…

Task 8 - Induction Systems In order for combustion to take place an induction system is required to feed fuel and air into the cylinder of an engine. To improve efficiency and performance spark ignition (SI) engines are now adopting compression ignition (CI) engine technology by injecting fuel directly into the cylinder just before the point of ignition however these engines still require an air induction system. Carburettors: before fuel injection technology had been fully developed carburettors (carbs) were used to create a fuel/air ratio at different engine speeds and loads. A cold start facility was also fitted albeit manually operated. The demand for more performance has meant the fixed choke carb' was no longer suitable. More complex carbs' were developed (twin choke) as well as variable choke (constant depression) carbs which used engine vacuum (during throttle opening) to vary the size of choke according to operating requirements.

A pick and Place machine is being used to transfer a box. The arm is extended (out) by energizing a solenoid valve; when the valve is de-energizes, the arm retracts (in). In the same way, a second valve closes the grip (when energized) or opens the grip (when de-energized). Here's a diagram of this "machine": Grip Air Cylinder Grip open Grip Closed Box Arm Air Cylinder Arm In Arm Out The system is really slow... it actually takes 3-4 seconds for the arm to fully extend. An engineer created the below diagram. Start Pressed Time (seconds) Box Falls - 1 -2 -3 - 4 - 5 -6 –7 -8 – 9 – 10 Extend Arm Close Grip Question (finally!). Which statement is completely true regarding this design? It uses the Master Clock scheme. Given this diagram, the arm will probably start to retract before the grip fully closes. O If the arm takes 4 seconds to retract (return), the box will be dropped "mid-flight" It uses the Domino Scheme. Things can't happen in the wrong sequence. It uses the Master Clock…

Please help me .. answer my Question , I don't want to quote or plagiarize, don't use your handwriting just use MS Word .

i-Use the first law of thermodynamics to determine an algebraic equation for the combustorexit temperature (T 04 ) in terms of equivalence ratio (phi) if the fuel in Problem 2 is used. Hint:find the equation for f in terms of T04 and T03 in the canvas handout, our class notes, or in thetextbook in Chpt 5. Then solve that equation for T04 .Assume that the compressor exit temperature T 03 is 650 K. The heating value (Q R ) of thenew fuel in problem 2 is 39,000 kJ/kg fuel. The effective heat capacity cp of the mixture is constant and is 1.2 kJ/(kg-K). Insert these values into your equation for (T 04 ) in terms ofequivalence ratio (phi)   ii-Now consider values of fuel-air equivalence ratios (phi) of 0.1, 0.2, 0.3, 0.4, 0.5. Use Matlab,Excel or some other program to use your equation from problem 2 to plot a graph of T04versus f. You have just computed the “adiabatic flame temperature”; the turbojet / turbofan engine designer can decide what fuel-air ratio to use to achieve the desired…

The level of liquid in a reboiler on a distillation column is controlled by using feedback control to throttle a valve on the liquid product (see below P&ID). However, the pressure of vapour above the liquid in the reboiler also affects the flow rate of liquid product, as an increase in pressure above the liquid will push the liquid through the product line faster. a) Draw a cascade arrangement where the vapour pressure is measured as the secondary variable. b) Draw a cascade arrangement where the actual flowrate in the liquid product stream is measured as the secondary variable.
