The paper presents a new method for diagnosing an internal combustion engine with compression ignition under traction conditions. The gist lies in determining the engine torque on the basis of acceleration recording in traffic conditions. The results of extensive preliminary and basic experimental studies have been discussed. Three options have been developed of the internal combustion engine diagnostic model, using the trivalent assessment of states. State control and engine damage localization algorithms have been proposed. The new method has been examined under traction conditions. The probability of the internal combustion engine correct diagnosis ranges between 0.85÷1.

The results of numerical analysis the combustion process in turbocharged CI engine 6CT107 are presented in the paper. Engine was installed on the ANDORIA’s power generator of 100 kVA/80 kW. The results of modelling the combustion process for different angle setting fuel injection, compared with the results obtained by indicating the real engine. Numerical analysis was performed in two programs, designed for three-dimensional modelling of the thermal cycle the piston internal combustion engine, namely AVL FIRE and the KIVA-3V.

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.

The piston secondary motion significantly influences the tribologicalcharacteristics in an internal combustion engine, such as the piston slapphenomenon and the frictional power loss.An analytical treatment was conducted to investigate piston motion and a computer program was written to predict optimum designs for high mechanical efficiency. This paper focuses on an analysis of the piston dynamic response. By coupling FDM for thehydrodynamic pressure field with the FEM for the piston deformation, wenumerically approximate the lubricantstructure interaction in an internalcombustion engine.
