On the Frequency Response of Engine Speed in Internal Combustion Engines 900615

So far the studies on the dynamic characteristic of internal combustion engines have been mainly carried out on the governor system and have led to development of a mathematical model more efficient for simulation and control purpose. But, there are still uncertain dynamic behaviors of the engine. The experiment and analysis on the transfer characteristic of effective torque and engine speed under a changing fuel feed quantity or brake load were carried out by using the frequency response and step response methods.
Consequently, it was confirmed that the transfer response of effective torque and engine speed to the changes in fuel feed quantity or brake load comprises a response time lag and its time constant is variable with the operating condition of the engine.
