analyze the performance of a gasoline engine at various loadsbased on data given and to determine the torque curve, power curveand performance parameters of BMEP, volumetric efficiency, andAir/fuel ratio, plotting the data vs RPM. Making three graphs: onegraphing Torque and Power.
Also address t
a. How do the torque curve and power curve compare (max values @same RPM)?
b. Is volumetric efficiency constant, or varying with RPM..whatis trend?
c. Is BMEP a constant? Does it compare more with torque or poweroutput?
