The simulation of gas flows in a reciprocating engine requires solution of the equations of gas dynamics because of the pressure waves in the manifolds, for example. The method of characteristics provides a means for solving hyperbolic partial differential equations. We propose in this paper a new way to implement this using ACSL software. After presenting an outline of the method of characteristics and ACSL software, we present a program to solve a simple case: a pressurized pipe with a gradually opening valve. The state event mechanism allows the boundary conditions and the intersections of the characteristics emitted from both ends of the pipe to be dealt with precisely while the solution of the differential equations is realized in a continuous fashion.

“…The quasi-dimensional thermodynamic simulation model has been used to simulate closed power cycle of CI engine comprising, injection timing, delay period, combustion, and expansion. The models developed by Whitehouse and Sareen [19], and Kumar et al [20], are being applied to simulate the Diesel engine working process and its spray mixing model. This model devides the mixture charge into burnt and unburnt zones; the burned zone corresponds to injected fuel and unburned zone corresponds to surrounding air.…”

Fuel burning rate plays a major role in optimizing the performance of internal combustion engine with reduced emission. In an attempt to optimize the performance of internal combustion engine, a novel empirical correlation is developed for fuel burning duration in tune with the methodology proposed by an earlier investigator for spark-ignition engine. The correlation was integrated with the quasi-dimensional mathematical model to analyse the combustion, performance and emission characteristics of engine. Engine speed and fuel injection timing were varied to assess the performance and corresponding exhaust emission of engine. Predictions relating to variation of burning duration with compression ratio at different equivalence ratios are in reasonable agreement with the published data on burning duration. The simulated results show that the optimum injection timing lies in the range of 23 °bTDC to 13 °bTDC for brake power and indicated power both, and the lowest brake specific fuel consumption and indicated specific fuel consumption were found close to 13 °bTDC. A sharp decrease in peak cylinder pressure was also observed with retarding injection timing, whereas both the retarding injection timing and increased engine speed accrue to reduced nitric oxide exhaust at exhaust valve open.
