In this paper a mathematical simulation of a simplified internal combustion engine is presented. To contribute engine kinematics and its geometry, simple relations are derived for constrained motions. The equation of motion for the piston forms a singular boundary value problem. The uniqueness of the solution was studied in the Banach space. For solving governing equations an iterative numerica...

This paper describes the simulative approach to calibrate an already extremely highly turbocharged industrial diesel engine for higher low-speed torque. The engine, which is operating at its cylinder-pressure maximum, achieve close 30 bar effective mean pressure through suitable calibration between compression ratio, piston-bowl shape and injection strategy. basic idea of study lower ratio even...

In this study, the combined effect of piston bowl geometry and fuel injection pressures on combustion, performance emission characteristics compression ignition (CI) engine fueled with baseline Diesel (D100) microalgae-biodiesel (MA100) was studied. paper, comparison study for two different geometry, namely: hemispherical combustion chamber (HCC) toroidal re-entrant (TRCC), carried out various ...

The cylinder working fluid mean temperature, rate of heat fluxes to combustion chamber and temperature distribution on combustion chamber surface will be calculated in this research. By simulating thermodynamic cycle of engine, temperature distribution of combustion chamber will be calculated by the Crank-Nicolson method. An implicit finite difference method was used in this code. Special treat...

In this work we demonstrate that the progress of the combustion cycle in a four-cylinder (in-line) 1.9 1 direct injection Diesel engine can be studied effectively using different laser visualization techniques. Direct optical access to the piston bowl was facilitated by inserting quartz windows in one of the pistons. The flow field at the time of injection was characterized by seeding the flow ...

The present study uses a numerical model to investigate the effects of flow turbulence on premixed iso-octane HCCI engine combustion. Different levels of in-cylinder turbulence are generated by using different piston geometries, namely a disc-shape versus a square-shape bowl. The numerical model is based on the KIVA code which is modified to use CHEMKIN as the chemistry solver. A detailed react...
