TL;DR: In this paper, the authors applied the method of Lavoie el al. to a spark-ignited carburetted IC engine and incorporated into the computer program the engine variables; fuel type, fuel air equivalence ratio, humidity content of inlet air, % exhaust gas recirculation, inlet manifold temperature, manifold pressure, RPM, compression ratio, piston connecting rod to crank ratio, and duration and position of combustion in the cycle.

TL;DR: In this paper, a model of the four-stroke S.I. engine cycle is developed which predicts fuel consumption, NOx and HC emissions as a function of engine design and operating conditions.

TL;DR: In this paper, a review of the state-of-the-art phenomenological modeling capability of internal combustion engines can be found, which can be used as a baseline for future work, be it of a phenomenological or detailed type.

TL;DR: In this paper, a model for calculating NO emissions for stratified charge engines in which the fuel is completely vaporized prior to combustion was developed. But the validity of the model is limited to single chamber geometry as it does not treat bulk gas motion typical of prechamber or divided chamber designs.

TL;DR: The first phase of the project consists of four months of applied research, starting from September 1, 2005 and was completed by December 31, 2005 as mentioned in this paper, during which time, the project team heavily relied on highly detailed numerical modeling techniques to evaluate the feasibility of the APA technology.
