A digital computer model of a diesel engine and load is developed
which takes into account in cycle calculations the input temperature and
pressure, mass of fuel injected, angle of injection, and cylinder temperature
and pressure, and gives as outputs the average torque and speed. A
typical heat release curve from a practical engine test is used with
ignition delay considered constant in time. Results from the program are
validated by comparison with data taken from laboratory engine tests.
This model is subsequently linearized to obtain the transfer function
matrix relating input manifold pressure, mass of fuel injected, and angle
of advance to output torque and speed.
The design of a feedback controller is then investigated using pole
and zero placement techniques, the system inputs and outputs being demanded
and achieved torque and speed .
