please dinot copy paste from other web i need urgent A petrol engine produces 250 kW while using 1.014 kg of fuel per minute. The fuel has a lower heating value of 45000 kJ/kg, and the engine has bore of 100 mm and the stroke-to-bore ratio of 1.2. The clearance volume of the cylinder is 1.178×105 mm3. The friction power is found to be 10% of the power that engine produces. Sketch (your own) the simple neat and clean block diagram of the engine, clearly indicating the control volume and control surface, with all the given data displayed on it. For air take the value of g = 1.4. Determine the following: The brake thermal efficiency (hb, th ). The indicated thermal efficiency (hind,th ). The mechanical efficiency (hmech ). The brake engine efficiency (hb ). The indicated engine efficiency (hind ). (Hint: Engine efficiency is a function of how the ideal work or power is calculated. Frequently, the air-standard cycle is used for calculating the theoretical work.) Use standard symbols…
During coastdown testing of a family passenger car, the following road load drag force characteristic was derived: FRL = 0.392v²+162 Where FRL is given in Newtons, and v, the vehicle speed in m/s. It is desired that the vehicle should have a top speed of 200km/h. Assuming a transmission efficiency of 90%, which of the following engines would be most suitable?

As a mechanical engineer, you were asked by your supervisor to monitor the operation of 4-stroke engine; as a result you got the following readings: > Imep = 780 kN/ m2 > Engine speed = 800 rpm > Brake Power 30 kW %3D %3D > nm = 85 % > B/S 0.7 You noticed also, that the inlet valve opens 10° before TDC and closes40° after BDC and it takes 0.0035 second after ignition for the charge to gain maximum pressure. Depending on the above readings, find the following engine parameters: a. The crank angle when the spark occursfor the maximum pressure to be at TDC b. The time period in second of inlet valve opening during one cycle c. The diameter of the engine d. The average piston speed 1 Upload file

Assuming nm =80% and an indicated mean effective pressure of 9.5 bar, determine the required bore and stroke. If the compression ratio of the engine is to be 7.5 to 1, determine consumption of petrol in kg/h and in kg/bp.hr. Take the ratio of the indicated thermal efficiency of the engine to that of the constant volume air standard cycle as 0.65 and the calorific value of the petrol as; 44770KJ/kg.

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!
