Performance Test of a Compression Ignition Engine.

MethodAfter whollyowing the railway locomotive to warm up the fuel control was batch to maximum. Initi totallyy starting with no-load, the dynamometer loading was increased and all data was recorded in the ?Observed Results? t dependent (page 5) sooner increasing the load and repeating. My investigation of my results comprised 3 conk outs. portion A: Measure/ modulate the performance of the compression inflaming engine. using my recorded results from the ?Observed Results? table, I enumerated:? dress brake motive (kW)? halt Mean Effect of Pressure, (Bp) (kN/m2)?Brake specific aro occasion Consumption (L/kW ? hr)?Brake thermal efficiencyThese were therefore remark in ?Calculated Results: add-in A? (Page 6). I then proceeded to construct interprets of Torque, Power, Brake Specific raise Consumption and thermal Efficiency against the Brake Mean utile Pressure (B.M.E.P) (Pages 7 ? 10). Part B: Measure/Determine the mechanical losings in the engine by extrapolating the Willans line. For part B I plotted a graph of dismiss Consumption versus the B.M.E.P which allowed me to account the mechanical losses in the engine (page 11). Part C: Measure/Determine the shake up losses. From my spy results I was able to determine:?Heat of flame of fuel, H1?Brake Power output, P?Heat to exhaust, H2?Heating to cool water, Q1?Other losses, Q2These values where say in Calculated Results: Table B: Heat losses (page 12).

These values allowed me to further calculate the percentage values of where heat losses occurred and to plot the graph of Percentage Heat losings against B.M.E.PTheoryAs engine f number was observed in revolutions per second (rps) it was req! uisite to convert this into revolutions per minute (rpm) to use in further calculations. This was achieved by multiplying the rps value by 60;Engine Speed, (rpm)Brake Power is the intersection of torque and engine speed (N). However calculation of Brake Power must work into account that the dynamometer has a related constant. Brake Power,The recall effective...
