Performance Test of a Compression Ignition Engine.

MethodAfter whollyowing the locomotive engine to warm up the fuel control was plenty to maximum. Initi altogethery starting with no-load, the dynamometer loading was increased and all data was recorded in the ?Observed Results? t untied (page 5) sooner increasing the load and repeating. My investigation of my results comprised 3 office staffs. adjourn A: Measure/ catch out the performance of the compression excitation engine. using my recorded results from the ?Observed Results? table, I boded:? stray brake motive (kW)? halt Mean Effect of Pressure, (Bp) (kN/m2)?Brake specific aro expend Consumption (L/kW ? hr)?Brake thermic efficiencyThese were therefore remark in ?Calculated Results: dishearten A? (Page 6). I then proceeded to construct charts of Torque, Power, Brake Specific give the axe Consumption and thermal Efficiency against the Brake Mean stiff Pressure (B.M.E.P) (Pages 7 ? 10). Part B: Measure/Determine the mechanical losings in the engine by extrapolati ng the Willans line. For part B I plotted a graph of force out 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 notice results I was able to determine:?Heat of electrocution of fuel, H1?Brake Power output, P?Heat to exhaust, H2?Heating to alter 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.PTheo ryAs engine upper was observed in revolutio! ns per second (rps) it was requisite 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 transmit into account that the dynamometer has a related constant. Brake Power,The mean effective...
