Abstract An advanced computational fluid dynamics package, REFLEQS, has been adapted to calculate the flow in the induction system of an internal combustion engine. Results of complex flow fields in multi-valve engine intake/exhaust ports and cylinders, including moving valves and piston, are calculated. The body-fitted structured grids generated with partial differential equations method have been applied to represent complex engine components configuration such as engine intake/exhaust ports, ducts, valves and cylinders. An upwind scheme combined with SIMPLEC method is employed to solve the Navier-Stokes equations. Several 2D and 3D flows in engine ports/cylinders are simulated. Complex flow fields involve separated flows near the entry of cylinder head, vortices near the corner and behind the valves and the valve/stem generated swirling and tumbling flows. The present work aims at establishing a generalized computational environment for analyzing the physical mechanisms and design parameters controlling internal flows in automotive air/fuel induction systems.

Ozone combustion-supporting is an effective means of internal combustion engine energy-saving. The theory of plasma method to produce ozone is mature, and how to improve the efficiency of ozone reaction becomes the key point. The chemical reaction process under the conditions of plasma involves the physical parameters and problems of gas discharge. Withal, research on the DBD (dielectric barrier discharge) experiments is carried on. And the key factors of improving the efficiency of the reaction, such as the physical parameters of discharge uniformity and the discharge power, are examined.

Abstract The performance of an internal-combustion engine may be influenced favorably or unfavorably by the vibration of the gas in the manifold. The analysis of this complicated action involves techniques which are not generally established nor widely known. This paper gives an introduction to these various techniques and their co-ordination. Included is a discussion of the vibration characteristics with damping for a tube, details as to numerical computations, and an outline of the analysis for a simple induction system.
