(b) Identify the following:

(1) the components or subassemblies that impose the limitations.

(2) the most adverse consequence should the limitations be disregarded.

(3) the possible design modifications 'and/or alterations which you believe will permit the diesel engine to overcomo any limitations and to meet its intended function.

(c) With these limitations discussed above, provide the power output versus operating time in either tabular or graphical form over the entire poser output ronde of the diesel units (i.e., 100 percent of rated power to zero power output).
