heal.abstract	A two-dimensional multi-zone model for the calculation of the cycle of direct injection diesel engines with swirl is presented, the fuel spray being divided into small packages. The effect of air velocity pattern on spray development is taken into account, the air entrainment into the fuel packages being governed by their penetration. The influence of the expansion-induced diffusion after ignition is included. Application of the mass, energy and state equations in each zone yields local temperature and cylinder pressure histories. In order to calculate the concentration of constituents in the exhaust gases, a complete chemical equilibrium scheme is adopted for the C-H-O system of the eleven species considered together with chemical rate equations for the calculation of nitric oxide (NO). A model for the evaluation of soot formation and oxidation rates is incorporated. The evaluation of swirl intensity variations during the cycle is based on a solid body rotation scheme. A comparison is made between the theoretical results from the computer program implementing the analysis with experimental results from the literature.	en
