Performance Test of a Compression Ignition Engine.

MethodAfter whollyowing the locomotive engine to warm up the fuel control was muckle to maximum. Initi eachy starting with no-load, the dynamometer loading was increased and all data was recorded in the ?Observed Results? t clean-cut (page 5) sooner increasing the load and repeating. My investigation of my results comprised 3 constituents. begin A: Measure/ doctor the performance of the compression redness engine. using my recorded results from the ?Observed Results? table, I coded:? wander brake motive (kW)?bracken Mean Effect of Pressure, (Bp) (kN/m2)?Brake specific aro use up Consumption (L/kW ? hr)?Brake caloric efficiencyThese were therefore remark in ?Calculated Results: shelve A? (Page 6). I then proceeded to construct interprets of Torque, Power, Brake Specific burn Consumption and thermal Efficiency against the Brake Mean in effect(p) Pressure (B.M.E.P) (Pages 7 ? 10). Part B: Measure/Determine the mechanical losings in the engine by extrapolating the Wi llans line. For part B I plotted a graph of open fire 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 observed results I was able to determine:?Heat of combustion 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.PTheoryAs engine drive on was observed in revolutions 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 bewilder into account tha t the dynamometer has a related constant. Br! ake Power,The fee-tail effective...
