+   The acausal bond graph of system \textbf{DieselCycle} is
+   displayed in Figure \Ref{DieselCycle_abg} and its label
+   file is listed in Section \Ref{sec:DieselCycle_lbl}.
+   The subsystems are listed in Section \Ref{sec:DieselCycle_sub}.
+
+
+The Diesel cycle is a simple closed thermodynamic cycle with four parts:
+\begin{enumerate}
+\item Isentropic compression
+\item Heating at constant pressure
+\item Isentropic expansion
+\item Cooling at constant volume
+\end{enumerate}
+
+The subsystem \textbf{Cycle} (Section \Ref{sec:Cycle}) is a two-port
+component describing an ideal gas. It has two energy ports which, with
+integral causality correspond to
+\begin{enumerate}
+\item Entropy flow in; temperature out
+\item Volume rate of change in; pressure out
+\end{enumerate}
+
+In contast to the Otto cycle (see Table
+\Ref{tab:cycles} where each table entry gives the causality on the
+heat and work ports respectively). The ideal Diesel cycle has
+derivative causality on the {\bf [Work]} port for one part of the
+cycle.
+
+To avoid this causality change, the Diesel cycle is approximated by
+applying the volume change from a pressure source via a resistance
+{\bf R} component. During the {\em heat injection\/} part of the
+cycle, the resistance parameter $r\approx 0$, but during the other parts of
+the cycle, the resistance parameter $r\approx \inf$.
+
+The simulation parameters appear in Section
+\Ref{sec:DieselCycle_numpar.txt}. The results are plotted against time
+as follows:
+\begin{itemize}
+\item Volume (Figure \Ref{fig:DieselCycle_odeso.ps-DieselCycle-cycle-V})
+\item Pressure (Figure
+\Ref{fig:DieselCycle_odeso.ps-DieselCycle-cycle-P})
+\item Entropy (Figure \Ref{fig:DieselCycle_odeso.ps-DieselCycle-cycle-S})
+\item Temperature (Figure
+\Ref{fig:DieselCycle_odeso.ps-DieselCycle-cycle-T})
+\end{itemize}
+
+These values are replotted as the standard PV and TS diagrams in
+Figures
+\Ref{fig:DieselCycle_odeso.ps-DieselCycle-cycle-V:DieselCycle-cycle-P}
+and
+\Ref{fig:DieselCycle_odeso.ps-DieselCycle-cycle-S:DieselCycle-cycle-T}
+respectively.
